Document Type and Number:
WIPO Patent Application WO/2022/089735
Kind Code:
A9
Abstract:
The invention relates to a method and a device (1) for joining a reinforcement sleeve (3) on a rotor (5) of an electric motor. The method comprises the steps of: providing the reinforcement sleeve (3) and the rotor (5), the reinforcement sleeve (5) having a cylindrical inner circumference which has an underdimension in respect of a cylindrical outer circumference of the rotor (5); attaching at least two vacuum suckers (9) on an outer lateral surface (27) of the reinforcement sleeve (3) in such a way that the vacuum suckers (9) adhere reversibly detachably to the outer lateral surface (27) of the reinforcement sleeve (3) by reason of a vacuum generated between the vacuum suckers (9) and the outer lateral surface (27); and joining the reinforcement sleeve (3) to the rotor (5) by pressing the rotor (5) into the reinforcement sleeve (3) in a pressing direction (15), forces acting in the pressing direction (15) being transferred from the vacuum suckers (9) to the reinforcement sleeve (3).
