<P>PROBLEM TO BE SOLVED: To simply unite a hollow shaft rotary encoder to a shaft with a large retaining torque. <P>SOLUTION: In the hollow shaft rotary encoder 40, a hollow shaft 42 is fitted to its encoder body 41 in such a way as to be rotatable freely. A female thread 45c is formed in the motor shaft 45. One end surface 42a of the hollow shaft 42 is put opposite to on end surface 45a of the motor shaft 45, and a bolt 47 is inserted into the hollow shaft 42 and is screwed into the female thread 45c of the motor shaft 45. Then the hollow shaft 42 is pushed to the motor shaft 45, and a large retaining torque is obtained. Besides, positioning can be performed easily by inserting spring pins 46 into drilled holes 42b, 45b when fitting is performed, and fitting can be performed easily only by screwing the bolt 47 in such a positioned state as this. Only to loosen the bolt 47 is enough to perform detachment. <P>COPYRIGHT: (C)2004,JPO |
