ABSTRACT:
A potentiometer drive for the displacement transducer of a reciprocating unit which uses a timing belt to drive the rotary potentiometer and where one belt pulley serves as a control disc to which the drive shaft of the rotary potentiometer is coupled in a direct rigid connection. The coupling connection is obtained by means of a coupling collet which clamps the end portion of the potentiometer drive shaft to a hollow hub of control disc and the latter to the inner races of two ball bearings. The potentiometer housing is blocked against rotation in a "floating" configuration, using a radial pin on the housing which engages a stationary retaining fork in such a way that only circumferential antirotation forces are transmittable to the potentiometer housing.
