LIMIT MOMENT COUPLING Russian patent published in 2017 - IPC F16D7/10 

FIELD: machine engineering.

SUBSTANCE: coupling comprises a body, configured to be rigidly connected to the drive shaft. The outer bearing collars of radial-thrust bearings with conical rollers are connected with the body. The inner collar of one of the bearings is rigidly fixed to the driven shaft. The inner collar of the second bearing is mounted on the driven shaft with the possibility of axial movement without rotation with respect thereof by means of an adjusting nut. Between the adjusting nut and the inner collar of the second bearing, there is an elastic element in the form of disc spring with a compliance that exceeds the compliance of the driven shaft when the bearings are heated during rotation.

EFFECT: stability of the torque value transmitted to the driven shaft.
