  • Patent number: 8646350
    Abstract: The actuator has a gear unit with a gear housing and a motor unit with a motor housing and an internally located rotor with a drive shaft, and a cylindrical bearing housing on the drive side. The bearing housing protrudes, along with a bearing and the drive shaft ducted therein, into an opening in the gear housing. The motor housing is flange-mounted, along with a drive shaft mounted therein, to the gear housing. The outside of the bearing housing and the inside of the opening in the gear housing have been geometrically mutually harmonized such that clamping points and tension-free places will form between them when the actuator has been assembled. The pretensioning force resulting therefrom produces a permanent frictional engagement between the outer circumference of the bearing and the bearing support or the bearing shell located opposite it. The operating life of an actuator of such type is increased.

  • Publication number: 20090243273
    Abstract: The invention relates to a belt tensioning drive which has an electric motor, a gear shaft and an output wheel. The electric motor drives the gear shaft via a first gear which is a worm gear. The gear shaft, for its part, uses a second gear to drive the output wheel which is connected in a rotationally fixed manner to the winding shaft of the seatbelt. This second gear is also a worm gear.

  • Publication number: 20090121580
    Abstract: A brush system for a motor vehicle actuating drive has two carbon brushes, of which each is fixed to a leaf spring. Each of the leaf springs is for its part fixed to a punched contact. Furthermore, the brush system contains a printed circuit board which has conductor tracks and on which interference suppression components are placed. Electrical contact is made with the leaf springs by in each case one of the conductor tracks.

  • Publication number: 20070013248
    Abstract: The electric machine has a stator, a rotor with a rotor shaft and a bearing. One end of the rotor shaft is guided in the bearing which is inserted into a clamping nut in the axial direction. The clamping nut is fixed into a housing together with the bearing. The clamping nut forms a pot bearing, which axially limits the end of the rotor shaft guided by the bearing. The pot bearing is an axially tapered cylindrical appendage of the clamping nut which forms a springing element acting essentially axially for a possible axial movement of the pot bearing. The clamping nut effects the attachment of the engine-side bearing in the housing of the electric machine and at the same time an axial limitation of the rotor shaft in the sense of a tolerance compensation or axial compensation. The component and assembly complexity for the electric machine are hereby reduced.
