5. Coupling with Other Machines
CAUTION
●Confirm the direction of rotation before coupling the unit with the driven machine.
Difference in the direction of rotation may cause injury or damage to the equipment.
●When operating the reducer alone (uncoupled), remove the key that is temporarily
attached to the output shaft; otherwise, injury may result.
●Cover the rotating parts; otherwise, injury may result.
●When coupling the reducer with load, check that the centering, the belt tension and
parallelism of the pulleys are within the specified limits. When the unit is directly coupled
with another machine, check that the direct coupling accuracy is within the specified limits.
When a belt is used for coupling the unit with another machine, check the belt tension.
Correctly tighten bolts on the pulley and coupling before operation; otherwise, injury may
result because of misalignment.
(1) The standard output shaft of reducer is straight type. Recommend to use some kinds of
coupling which are not generated backlash at the coupling part.
(2) In case radial load is put on output shaft, do not exceed the value in the attached table,
"Standard model table".
(3) When output shaft is installed in coupling, do not force into it so that bearing may be
damaged.
5—1) Coupling Installation
• When installing a coupling, do not impact or apply excessive thrust load to the shaft;
otherwise, the bearing may be damaged or collar may be left.
• Thermal shrinking is the recommended installation method.
• When chain sprockets, gears or pullers are coupled with the reducer, please use within
the range of the allowable radial axial load, or shaft and bearing may be damaged.

(2) When Using a Chain Sprocket and Gear
• The chain tension angle should be perpendicular to the shaft.
• Refer to the chain catalog for the chain tension.
• Select sprockets and gears whose pitch diameter are three times the shaft diameter or
geater.
•Install sprocket and gears so that their point of load application will be closer to the
recucer side with respect to the length of the shaft. (Fig.3)
(3) When Using a V-belt
• Excessive V-belt tension will damage the shaft and bearing. Refer to the V-belt catalog
for proper tension.
• The parallelism and eccentricity (ß) between two pulleys should be within 20'. (Fig.4)
• Use a matchend set with the same circumferential length when more than one belt is to
be installed.

8. Instructing Motor Installation
This is the construction anyone can connect with motor because the coupling is used at the shaft
coupling part between reducer and motor.
Assemble them as the following instruction.
(1) Put the reducer on the proper table so that the slow speed shaft is facing down.
(2) Put hub(1), spacer, and hub(2) of the coupling which are equipped with the input shaft of
the reducer in order, and push them until clicks of the hub are engaged enough.
(3) Set the position manually so that clamping bolts of the hub(2) are fastened into the hole of
the slow speed end cap.
(4) Put the motor shaft into the center hole of the hub(2) and assemble perpendicularly
cover and motor.
(5) Fasten the motor with the slow speed end cap with motor installation bolt.
(6) Fasten the coupling bolt with hexagon head from the setting hole in the side of the slow
speed end cap referring the clamping torque in the table 3.

Because the special coupling is used at the coupling part between reducer and motor, it is
possible to install either straight shaft, shaft with key groove, or D-cut shaft. Install it as the
following instruction.
(1) Set the coupling unified with primary sun gear into motor shaft. Set the tip of sun gear from
the motor flange side for size in the table 5. (In case the size is out of the designated
range, reducer's life expectancy might be shortened.)
(2) Fasten the coupling bolt with hexagon head by clamping torque in the table 4.
(3) Put the reducer on the proper table so that the slow speed shaft is facing down.
(4) In case motor with shield is used, apply packing in liquid to the flange side of the slow
speed end cap because high speed shaft seal of the reducer is removed.
(5) Put motor primary sun gear is installed into perpendicularly without damaging high speed
end cap.
(6) Rotating primary sun gear along with motor manually and putting it into motor, each cog
meet well. Then, it is convenient to shorten power wire of motor.
(7) Finally fasten flanges of motor and of slow speed end cap with bolt and nuts.
