Abstract
A coupling system is configured to axially couple a motor shaft rotating in a motor housing to a gearbox shaft rotating in a gearbox housing. The coupling system has a set screw and a socket. The set screw couples the two housings together. The socket is configured to receive the set screw. The socket being configured to can slide in a first of the motor housing and the gearbox housing in a direction of a second of the motor housing and the gearbox housing under a thrust force of the set screw during tightening thereof, in order to press the socket against the second of the motor housing and the gearbox housing at a mating surface of the second of the motor housing and the gearbox housing, so as to eliminate any play between the second of the motor housing and the gearbox housing at the mating surface.
