Feedback coupler for mechanical connection of feedback device, has fastening unit that is provided at stretching and contraction unit such that unit is arranged at feedback device and counter bearing, where unit is realized by bellow

摘要

The coupler has a stretching and contraction unit (1) for compensating axial shaft movements, where the coupler is connected with a motor shaft variably supported in an axial direction. A fastening unit (5) is provided at the stretching and contraction unit such that the unit is arranged at the feedback device and at the counter bearing. The unit is realized by a bellow or a bellow-like device. The bellow is fixed at the feedback device and a motor housing by the fastening unit, and is formed of non-corroding metal or rubber or metal/rubber combination.
