Rotary encoder, has hollow shaft whose front surface and coupling unit are connected with each other, via ring disk having elastic property, along direction of longitudinal axis of coupling unit

摘要

The encoder (3) has a hollow shaft (3), which is rotatably supported in a housing, in which a sensing head and an incremental disk connected with the shaft are arranged. A hollow shaft clasps a coupling unit that encircles the shaft with play. The front surface of the hollow shaft and the coupling unit are connected with each other, via a ring disk having elastic property, along a direction of longitudinal axis of the coupling unit.
