5. Coupling with Other Machines
Common
CAUTION
- Check the rotation direction before coupling with its driven machine. Difference in the direction of rotation may cause injury
or damage to the equipment.
- Remove the key temporarily attached to the output shaft of the gearmotor or speed reducer, when the shaft is unattached to
any other vehicle (i.e.: not loaded);
otherwise the key could fly off, and injury may result.
- Install appropriate protective device around rotating parts; otherwise, injury may result.
- When coupling the gearmotor or speed reducer with other machine, pay attention to the alignment, belt tension, and paral-
lelism of pulleys. Pay attention to the direct coupling accuracy when the unit is directly coupled with another machine. When
a belt is used for coupling, adjust the belt tension correctly. Correctly fasten tightening bolts on the pulley and coupling be-
fore operation; otherwise, injury or damage to the equipment may result due to scattering fragments.
5-1 Confirming Rotation Direction and Location of Oil Filling/Drain Ports
(1) Gearmotor
- Directions of output shaft rotation with wiring shown on P23 - 36 and location of oil filling/drain ports are as shown in P10 - 14.
- When wiring is performed as shown on P23 - 36, the motor shaft rotates to the right as seen from the fan cover side.
- To cause reverse rotation, reverse R and T shown on P23 and P25 - 36.
(2) Speed Reducer
- In the case where the input shaft rotates clockwise, the direction of the output shaft is as the arrow direction shown in P10 to 14.
Check it as well as the position of the oil filling/drain ports.
