An assembly for applying a torque from an output shaft to an input shaft of an apparatus, such as a multishaft extruder, and for measuring the applied torque. The assembly includes a connecting sleeve for torque-transmittingly coupling the output shaft with the input shaft; and a torque measuring device having expansion measuring strips, a signal amplifier, a transmitting ring antenna and a receiving antenna. The connecting sleeve has a first length portion carrying the expansion measuring strips and a second length portion carrying the signal amplifier and the transmitting ring antenna. A torque-transmitting arrangement torque-transmittingly couples solely the first length portion of the connecting sleeve with the output shaft and the input shaft, so that the second length portion of the connecting sleeve is free from a torque-transmitting connection with the input shaft.

Torque measuring device particularly for a multishaft extruder

A throttle device for a twin-shaft screw machine having a housing with two mutually penetrating bores in which respective screw shafts are arranged. Each bore has an outer gap sleeve and each shaft has an inner gap sleeve, the sleeves being mutually axially displaceable in order to generate or modify a throttle gap therebetween. The throttle gaps are formed, in each case, between cylindrical outer circumference on the respective inner gap sleeve and a cylindrical internal bore on the respective outer gap sleeve to provide an annular cylindrical gap of constant width but variable length. Each outer gap sleeve is connected to at least one sliding bolt which passes through an associated slot in the housing and through which the outer gap sleeve can be moved axially from outside the housing.
