5. INSTALLATION
5 - 7
• Since a precision encoder is directly connected to the motor shaft, be careful not to give shocks to it.
If tapping on the motor is unavoidable for position adjustment or other reasons, tap on the front
flange, if possible, with a rubber or plastic hammer.
• When installing the motor to the machine, make a installing hole precisely so that the motor joint can
be smoothly connected. Also, make the installing surface as flat as possible, or the shaft or the
bearing may be damaged.
• When installing the gear, the pulley, the coupling, etc., avoid giving shocks to them by using the
screw on the shaft edge.
• Since torque is transferred, in the case of the tapered motor shaft, from the tapered surface, take
care that the key can be engaged without being tapped. Also, make a hole so that at least 70% of
the tapered surface is to be engaged.
• When removing the gear, the pulley, etc., use a dedicated extracting tool.
• When performing belt driving, check that the shaft-converted value of the belt tension does not
exceed the allowable value shown in Table 5-1.
● Allowable load of bearing
Fig. 5-1 shows the load which the Servomotor can endure.
Do not apply an excessive thrust or radial load.
The thrust or radial load in the table indicates the value when it is independently applied to the shaft.
