摘要

#CMT# #/CMT# The drive device has a rotor that is arranged in a stator of an electric motor. A rotor shaft (14) is extended along longitudinal axis of the rotor and connected with rotor of electric motor. The housing is connected to the electric motor. A ball bearing (5) is arranged to support rotor shaft at the housing. The socket (4) is radially arranged along longitudinal axis between ball bearing and rotor shaft to connect ball bearing with rotor shaft. #CMT#USE : #/CMT# Drive device for window lifter installed at door of motor vehicle. #CMT#ADVANTAGE : #/CMT# The socket is radially arranged along longitudinal axis between ball bearing and rotor shaft to connect ball bearing with rotor shaft such that the connection strength between ball bearing and rotor shaft can be improved and axial force can be transmitted sufficiently to the ball bearing during operation of drive device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the rotor shaft. 4 : Socket 5 : Ball bearing 14 : Rotor shaft 51 : Inner bearing 52 : Outer bearing.
