ASSEMBLY MECHANISM
In the process of repair mechanism is often necessary to its partial
disassembly for replacement parts that fail. The article describes the
assembly sequence that part of the mechanism, which ensures proper
phasing of its work, as well as methods of verification mechanism after
assembly.
The assembly is performed in the following sequence:

1. Fits gear due to a mechanism for loading cassettes and fixed split washer (Fig. 1).
2. Fits lever control efforts freezes podkassetnogo receiving node (Fig. 1).
3. Set the lever position P5 and gear drive clamp rollers (Fig. 1).
4. Installed base lock position P5 and fixed split washer and screw (Fig. 1).
5. Fits latch position P5, the bracket with rollers and opener magazine covers.
6. Supporting software installed gear so that the hole in it
coincided with a hole on the chassis of the mechanism, while the second
(small) hole must be matched with a hole in the gear drive pinch roller.
Position of gear can fix a pin that is removed after final assembly
(Fig. 2). Protrusion on the bracket with a pinch roller to be wound into
a groove on the auxiliary program gear.
7. Install the stator engine drive shaft and fix it with three
screws, keeping the alignment holes. After that, install the rotor
motor. On the drive shaft during installation should be dressed in two
glands (one above the other - at the bottom).
8. Installs the gear, rotating the gear connection with the cassette
loading mechanism so that her teeth did not come into engagement with
the gear program. Give birth to a ledge regulator lever effort freezes
podkassetnogo receiving node in the slot program gears (Fig. 2).

COMMON FAULT

Consider the typical failure mechanisms and their causes.

1. Cassette is not loaded or unloaded:

  • broken cassette holder (VXA4661)
  • "Propylene" teeth on the gear lever boot tape (VXP1339);
  • faulty or improperly installed switch mechanism.

2. Tape is not threaded through:

  • faulty braking mechanism podkassetnyh nodes;
  • broken teeth on the drive gear lever filling tapes;
  • program is broken strap.

3. Does not reach the stop lever filling the tape:

  • dirty guide slot chassis or dry lubrication;
  • defective mechanism freezes podkassetnyh nodes.

4. Press down tape:

  • is defective or not configured the ribbon (often Unstick felt strip);
  • dirty or warped pressure roller;
  • bent arm position P5.

5. Tape is not moving in the playback mode:

  • improperly installed or defective drive bracket with the pinch roller;
  • defective central clutch that transmits rotation podkassetnye nodes. 6. Tape is not at podmatyvaetsya raspravke:
  • faulty braking mechanism podkassetnogo receiving node (VXZ0313).

7. Crashes when you change modes:

  • faulty switch mechanism;
  • crack in program bar (in this case usually fails the phasing mechanism.)

8. Shutter does not open when unloading the cassette tape:

  • broken arm opening blinds (VXL2250);
  • broken shutter (VKF2709).

9. Cover will not open the cassette upon startup:

  • broken arm (VML2680), mounted on the cassette holder;
  • broken opener magazine covers (VDM2101).

It should be noted that the reason of incorrect work may be the
mechanism of its contamination or ingestion of foreign objects. In the
latter case, may damage the gears, the program bars and levers.


ADJUSTMENT MECHANISM
The need for mechanical adjustments tape mechanism occurs after
prolonged use, the replacement of any of its parts, as well as due to
unauthorized repairs.

ADJUSTING THE ARM the ribbon

1. Remove the top panel with the cassette and cassette holder.
2. Rotate the engine load to bring the mechanism to the position filled by the tape.
3. With the holes in the eccentric holder belt controller belt
tension adjusting the position of the lever. The left edge of the lever
must match the left edge of the clip (see Figure 9)..

ADJUSTING THE TENSION BAND

1. Enables playback (mounted on top of the tape length 180 minutes) and give the tape to stabilize (approximately 10 ... 20).
2. Measure belt tension in the area between the head full erase and
fasting P2 (see Fig. 10) with a meter (VFK 0132). Meter reading should
be between 22.5 ... 27.5, the
3. If the belt tension does not fit into these limits, adjust it,
moving the governor spring tension belts on short-or long tooth (in the
original position it is on the average).


PROVISIONAL ADJUSTMENT POSTS P2 and P3


[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
Fig. 10 Location of posts

1. Remove the top panel with the cassette and cassette holder.
2. Weaken the fixing screws positions P2 and P3.
3. Rotating positions P2 and P3 in a clockwise direction, set them in the lowest position.
4. Pivoted to positions P2 and P3 2 turns counterclockwise.
5. Set the cassette holder and the top panel cassette.
6. Load the tape and start playback. Verify the absence of knee tape
in the upper and lower floors of the restrictive positions P1, P2, P3,
P4.
7. In the case of bending strip remove him adjusting positions P2 and P3.
8. Setting compatibility BM (substitutability tapes).

To configure the compatibility of the VM should do the following:

1. Adjustment positions P2 and P3;
2. Preliminary adjustment of the block of magnetic heads (BMG) in height;
3. Height adjustment BMG;
4. Precise control of BMG;
5. Adjusting the BMG horizontally. Before you begin, you should
disable the auto-tracking. To this end, the microcontroller is converted
into service mode jumper between control points:

  • TP SERV and TP GND for a series of SD;
  • TP 6010 and TP 6011 series HD.

Voltage at NORM / SERV / TEST MCU in this case is 2,5 ... 4 B. At the end of the jumper settings are removed.

If the envelope of the RF-signal at the input tape in contact with
the video heads (when you turn on the video heads) has the form shown in
Fig. 11A or 11B, it is necessary to adjust the position P2 to obtain
the waveform shown in Fig. 11C. If the envelope of the RF-signal at the
output tape from contact with the video heads (when you turn off the
video heads) has the form shown in Fig. 12D or 12E, you should adjust
the position P3 for the waveform shown in Fig. 12F. Adjusting the
tracking in either direction from the central position, you must make
sure that the shape of the envelope corresponds to that shown in Fig.
13.V if necessary, further adjust positions P2 and P3.

Turning the screws B and C, set the database D with respect to the
base E, as shown in Fig. 14. When adjusting the screws B and C are not
allowed to touch the surface with a screwdriver heads.

ADJUSTING THE HEIGHT BMG
In playback mode, rotate the screw A or until the bend ribbon at the
bottom of the post of P4, and then turn the screw in the opposite
direction until the disappearance of knee tape. Attach the oscilloscope
to the output audio channel, and turning the screw C, we achieve maximum
signal. The bottom edge of tape should be above the lower edge of the
magnetic sinhrogolovki BMG approximately 0.25 mm.

EXACT ADJUSTMENT OF THE HEIGHT BMG
If the position of tape does not match the above, then for BMG
lifting screw is rotated a counterclockwise until you bend ribbon at the
bottom of the post of P4. Then turn the screw in clockwise until the
disappearance of the bend the tape, and screw C until the maximum
amplitude of the signal. To lower BMG screws rotate in the same sequence
in a clockwise direction.

ALIGN BMG Horizontal
Set the tracking to the middle position, while pressing the TRACKING
"+" and "-" on the remote while playing a reference recording. Connect
the oscilloscope to the amplifier signal video heads (RF SIGNAL). Weaken
the screws holding the base E BMG to the chassis and turn the base, we
achieve maximum value envelope of the RF-signal.
After that anchoring base E screws.

SERVICE MODE

Service mode allows you to verify the operation of various units of
VM. In this case, the display shows information in the form of
facilities and rooms service mode data service, which allows to detect
faults and, thus, reduce the repair time.
Entry into service mode by simultaneously pressing the "FF" and
"Eject" (or turning the handle to position "FF" and click "Eject") on
the front panel of the VM. Switching service modes implemented in the
same way.
The display shows information in the form of four (or five) digits.
The first digit (a digit hour display) indicates which of the seven
service modes the machine. The second and third digits (digits in
minutes) - this service data indicating a position to verify the scheme
or mechanism. The fourth (or fourth and fifth - 01, 02, etc.) figure (in
the discharge of seconds) - is the number of service data that
indicates in any scheme to be a problem.
Customer information is not dependent on service conditions and
stored in memory after you turn off the VM from the network. Deriving
this information to the display is carried out in service mode 2.
Consider the appointment of service modes.

Mode 1
Checks the tape protection schemes, ie Work
emitting diode and photodetectors beginning and end of the tape by
blocking the radiation on the photocell.
Mode 2
Checks the circuit switch modes in the transition
mechanism from one position to another with an indication of the
mechanism in the form of service data.
Mode 3
Checks the circuit switch mode after completion of the transition mechanism from one position to another.
Mode 4
Checks of the control buttons on the display should
appear on the index (in the ranks of service data), corresponding to
each of the buttons.
Mode 5
Calibrated work of motor control circuit of the drive shaft, ie, transmission of commands from the microcontroller (MC).
Mode 6
Inspects the work of the motor control circuit SHIRBRIG.
Mode 7
Checks of the engine load. When the button is
pressed "Play", the engine load is rotated in the direction of loading.
When the button is pressed "Stop", the motor rotates in the direction of
discharge. This mode can be indicated by an unlimited time with power.

ELECTRICAL ADJUSTMENTS

Depending on the VM, the list of adjustable parameters can be
changed. For electrical adjustment requires the following hardware:

  • dual-trace oscilloscope with a frequency range up to 35 MHz;
  • frequency with a frequency range up to 10 MHz, with the ability to measure the period;
  • digital voltmeter;
  • Generator video sweep signal (video scan);
  • generator of sinusoidal signals;
  • video generator;
  • Measuring videofonogramma VFV8125H3F (PAL), VFM8080HQFP (NTSC);
  • net tape VHS;
  • monitor (TV);
  • DC power supply.

It should be noted that, depending on the model of the VM, the list
of adjustable parameters may vary considerably. Depending on the
location of the adjustment elements may vary their item numbers. May
also differ and the conditions under which carried out one or another
regulation.

G-Mechanism VCR PANASONIC



With what can be compared to assembling G-mechanism? More
all, with the assembly of three-dimensional puzzle, only
error will be noticed immediately, but after switching
VCR. This article will help you
Part Number identify the defective part, and after
replace it quickly and correctly assemble the mechanism.
There are three modifications of G-mechanism:
proper G, G-REV and GII, have small
structural differences, but performed by a single
kinematics. Such a mechanism
manned video recorders (VTR) Panasonic
Series G, H, J, L, etc., as well as some other VMs
firms (in particular, Grundig).
Due to relatively high consumer
qualities, VCR with G-mechanism are in
operation for quite a long
time. In this regard, coming into repair VM
often require the replacement of worn or
broken parts of the kinematics and its subsequent
adjustment, which causes some
difficulties due to the complexity of the mechanism.
In this paper we consider the kinematic
scheme of the mechanism and the assembly sequence of the
part of it, which requires phasing.
KINEMATIC PATTERN MECHANISM


On Fig. 1 shows a view from below
G-REV-mechanism.
Fig. Figure 2 shows the kinematic scheme
bottom, and Fig. 3 - upper part of this
mechanism. The diagram shows the relationship and
phasing of the details of the mechanism for the mode STOP.

Fig. 3. Kinematic diagram of the upper
part of the mechanism
Feature of the mechanism is that
loading cassettes and change regimes mechanism
carried out from the engine drive shaft (in the GII-mechanism
part of the operations carried out additional
engine). Rotation from the engine through
central sleeve and a leading disc is transferred to the
disc clutch. With this disc rotation
transmitted to the central and related
separator and ring gears. Separator
gear transmits rotation to the main
Soft pinion gear and software
filling the tape. The main program gear
a pinch roller drive gear
the moving of the drive mechanism
pinch roller and the mode switch, and
a lever connection - Software straps.
Pinion Software by filling tapes
notched transmits rotation to the gear
filling the tape.
Ring gear transmits rotation to the
Product Wizards gear, and by
it - on the pinion with rack
cassette.
ASSEMBLY and phasing MECHANISM


Consider the assembly sequence
mechanism in a part that requires the phasing.
Incorrect phasing mechanism can lead
its jamming and damage to components, so
after assembly mechanism is recommended that you manually
sweep without a greater effort to
ensure proper functioning.

  • Install the ring gear, combining
    a hole in it with a hole chassis as
    shown in Fig. 4. Then set
    Product Wizards gear, combining
    a hole in it with a hole in the chassis.
    In this case, a small hole must be
    opposite the holes in the ring gear. After
    This set the lock lever.
    [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
    Fig. 4. Install the ring gear
  • Install the upper side of the chassis
    gear drive pinch roller. Then
    establish a core program gear
    so that the small holes on it and on
    pinch roller drive gear were
    on one line. A large hole in the software
    gear should be in this match with a hole
    in the auxiliary program gear, as
    shown in Fig. 5.>

    tape so that the protrusion auxiliary lever
    Filling tape was combined with the groove (A) in it, as
    shown in Fig. 6. Rotate the gear so
    to a small hole in it was on
    in line with the axis of the ring gear as
    shown in Fig. 7. Then set
    separator gear with three planetary
    gear over the ring gear so that
    holes in it were in front of the holes in the
    Key Policy gear filling the tape. In
    Meanwhile, the hole in the separator gear
    should coincide with the opening in the ring
    gear, as shown in Fig. 8.

"Seals" for gear




Sometimes repairing tape drives
VCRs, camcorders, copiers and
other equipment, "rests" in a broken tooth
some gears (Fig. 1, sector 1).
Gear, this is either very expensive or her
virtually unobtainable. The author hopes
that the method described below, will be available to many
master repairmen.

Figure 1
For a start, made from paraffin
proofing gear. To do this from the paraffin candles
diameter of 25-40 mm cut cylinder of height 15-20 mm.
Then you need a well heated soldering iron with a thin
melt the wax from the end of the cylinder to 1 / 2
diameter and 1-2 mm deeper than the thickness of the pinion.
Further, in liquid paraffin should put that part of the
Gear that has all the integer teeth.
Addressing a soldering iron melted paraffin to
completely fill the entire space between
teeth. For safety you can drop the top 3.4
a drop of melted paraffin, then
must set aside this construction until
cooling and solidification of paraffin.
Once frozen paraffin, a scalpel or
cutter remove thin layers of its surplus with the
top gear (in Fig. 1, Sector 2 paraffin
visibility is covered with a thin layer of paint). Then
neat, a gentle lurch extract
gear from a paraffin cylinder. If something
did not work (defects in the prints, broke
excavation, etc.), the procedure is repeated until
get an even impression of the teeth.
Now you must prepare itself gear.
To do this, it will be convenient to use
mikrodrelyu for drilling circuit boards or small
drilling machine. Dental burs, already
unsuitable for dental treatment, but it is
suitable for such operations,
You can get it from any dentist. Incidentally, there
You can also purchase and mikroabrazivnye stones and
grinding wheels. A small dental bur
opposite the broken tooth in the body gear
milled notch (Fig. 1, Section 3). Depth
cavity is 2 / 3 or 3 / 4 the thickness of the gear.
Further, a gear must be properly
degrease. You can use the
brush and gasoline "Galoshes" or
solvent grade 646-647. While the gear dries
diluted with epoxy glue in traditional
proportions. His need quite a bit, but
should be very thoroughly mixed composite
part of the glue. Then selects the sharpest
imprint of teeth on the paraffin cylinder and a needle
filled with glue. After you do this as soon as possible
rather invest in gear notch up
imprint. Then embedded into the groove
"Fittings" - a piece of steel needles or
thin the broken drill bit. Desirable region
"Reinforcement" to be laying in the
paraffin imprint obtochit small
abrasive or sandpaper to shape the tooth, so
is, give it a wedge shape. After laying
"Reinforcement" to the edges of the recess is filled with glue and
drown in it short pieces of thin threads (Fig. 1,
Sector 4). Better if it would be Mylar,
kamelanovye or silk thread (they have
high strength). Needs to be monitored,
to thread properly impregnated with glue.
Resulting from the addition of adhesive thread bump
best left alone until the setting point.
After curing the adhesive gear removed from the
wax and needle files to remove the bump side
gears. If turned "litnichki"
between the teeth, they can cut blade
safety razor or nail file
(Diamond).
It remains to add that in this way
recovered a variety of traction,
brackets, hooks and gear the program
vehicles with mechanical logic.
