B-65262EN/03 SPECIFICATIONS FOR THE αiS/αi SERIES 2.HOW TO USE SERVO MOTORS
- 39 -
A precision sensor is directly connected to the servo motor shaft.
Pay attention to the following items to prevent damage to the sensor.
• When connecting the power transmission elements such as a
gear, a pulley and a coupling to the shaft, take care not to apply a
shock to the shaft.
• Generally, in the case of straight shaft, use a span ring for
connection with the shaft.
• In the case of tapered shaft, match the tapered surface with the
power transmission element and fix by tightening the screw at
the end. When the woodruff key is too tight, don't tap it with a
hammer. Use the woodruff key mainly for positioning, and use
the tapered surface for torque transmission. Machine the tapered
surface of the power transmission element so that over 70% of
the whole surface is contacted.
• To remove the connected power transmission element, be sure to
use a jig such as a gear puller.
