Abstract (en)
A rotary variable electrical resistance device comprises a housing (21); a spindle (22), arranged for rotation in the housing to adjust the setting of the device, and arranged to be rigidly secured to the end of a rotatably supported shaft serving as an extension of the spindle or whose angular rotation is to be monitored by the device and such that the shaft effectively supports the resistance device. The housing (21) is restrained from rotation by a member such as a pin (27) on a disc (23) secured to a support (24) by a ring shaped member (25) and engaging an opening or recess (28) in a flange (29) secured to the housing. Clearance between the members (25) and (29) allows the device to be displaced to follow displacement of the shaft resulting from play in bearings supporting the shaft or misalignment or bending of the shaft and obviates the necessity for the expensive and bulky flexible couplings of the prior art.
