Shimpo VRAL Series Assembly instructions

Thank you for purchasing the ABLE Servo Planetary Gear Reducer. We recommend you read this installation and instruction
sheet before operation to ensure proper performance. For wet environments, please follow the IP65 Protection procedures
on the reverse side.
A. Inspection
B. Mounting the Motor
The ABLE Servo Planetary Gear Reducer
is grease lubricated at the factory prior to
shipment. No additional lubrication is required.
The motor attachment flange and quill shaft (w/ bushing) of
the ABLE is machined for a specific servo motor. DO NOT
attempt to mount the ABLE to a different servo motor than
for the one it is manufactured.
C. Installation
Key is provided
1. Clean the machine surfaces of the motor attachment
flange with light oil, being careful not to disturb the
position of the O-Ring (if supplied).
2. Remove the plug from the access hole.
3. Position the unit vertically output shaft down.
4. Rotate the quill shaft until the clamp bolt in the collet
hub is aligned with the access hole.
5. Loosen the clamp bolt.
Motors with or without Keys
1. Unpack the ABLE and check to see that it is identical
to what is specified in the purchase order. Inspect
for shipping damage. Notify the shipping agent
immediately if damage is discovered.
2. Remove the protective tape from the output shaft and
clean the rust proof material with light oil.
3. An output shaft key is provided.
4. For some configurations, a shaft bushing (or sleeve) is
included to adapt the motor shaft to the reducer hub.
If included, the bushing is attached to the top of the
reducer with red tape. Do not lose the bushing, as it
is required for proper operation.
1. Install the ABLE in a location with plenty of
ventilation.
2. Proper ambient temperature is 32°F - 104°F (0°C -
40°C). Contact SHIMPO Drives Customer Service if the
unit must operate outside of this temperature range.
3. The ABLE should be bolted to a rigid, vibration free
frame.
4. The installation location should be convenient for
maintenance and inspection.

6. Insert the bushing (if supplied) into the quill shaft align-
ing the bushing slit with the slit in the collet hub.
7. Remove the motor key (if supplied) as it is not required
for proper installation and operation.
8. Insert the servo motor, making sure the motor keyway
(if supplied) is aligned with the slits in the collet hub and
bushing (if supplied).
9. Tighten the bolts for servo motor installation to the torque
specified in Table 1.
10. Tighten the clamp bolt in the collet hub to the torque
specified in Table 2.
11. Install the plug into the access hole, insuring that the
plug does not hit the clamp bolt in the collet hub.

1. When starting, check for correct rotational direction
of the output shaft and apply the load gradually.
2. Pay careful attention not to overload the unit.
3. Periodically inspect the unit. Stop the unit for
inspection if the following should occur:
a) Case temperature suddenly rises, or exceeds the
ambient temperature by 122° F (50° C)
b) Noise from the unit becomes louder
c) Vibration becomes abnormal
d) Rotational speed becomes unstable
e) Lubricant leakage
f) Other faults or defects are found
4. The following are possible causes of improper
operating conditions:
a) Faulty operation of the servo motor
b) Unit has become overloaded
c) Lubrication has deteriorated
d) Bearings or gears have been damaged
e) Connection between the ABLE and the servo
motor is improper (the clamp bolt on the ABLE
quill shaft has become loose)
f) Connection between the ABLE and the machine
is improper (set bolts on pulleys, couplings, etc.
have become loose)
G. IP65 Protection
ABLE with the last two characters in the part number
being “WD”, “SP”, or “65” have been factory supplied
with additional modifications for IP65 protection. Apply
ThreeBond 1121 or equivalent liquid sealant at position
“A” (between the motor attachment flange and the servo
motor) and position “B” (on the threads of the access
hole plug) to complete the IP65 protection.

Key
1. When installing couplings, pulleys, gears, etc. on the
shafts, do not apply impact or excessive thrust loads
to the output shaft. Mount all components as close to
the reducer housing as possible.
2. Shafts must be free from vibration, excessive impact,
radial, or thrust loads transmitted from the machine.
