  • Publication number: 20070001522
    Abstract: The present invention relates to a device for the elastic, vibration-damping accommodation of an assembly with respect to a mounting fixed to a frame, having at least one elastic element that is situated between the assembly and the mounting that is fixed to the frame, the assembly having at least one first support surface, and the mounting having at least one second support surface, and the two support surfaces face each other and run transversely, especially at right angles, to the vibrational plane of the vibration and, as seen in the direction of vibration, the elastic element lies in an overlapping position to the support surfaces. It is provided that the two support surfaces have a lateral clearance from each other, and that the first elastic element bridges the clearance in the form of a first free bridge.

  • Patent number: 6520708
    Abstract: In a device for connecting two parts for the sake of high-precision fixation of the two parts in a defined positioning to one another, two connection pairs are provided, each comprising one wedgelike tab, assigned to the first part and extending in the connection direction, and one wedge-shaped notch, assigned to the other part and extending in the connection direction, with a course of the wedge that is contrary to that to the tab, and into which notch the tab can be pressed, causing deformation. The two connection pairs are oriented such that the press-in directions of the tabs into the assigned notches are opposite one another in terms of the connection direction.

  • Publication number: 20020121836
    Abstract: A bearing plate for a commutator machine according to the related art is made of metal and comprises an applied brush holder made of plastic. Connector elements for electrical components on the brush holder are inserted in corresponding receptacles in the brush holder in a separate working step, however. In the bearing plate (1) according to the invention, the connector elements (4, 8, 11) are formed out of the bearing plate and are partially connected to the bearing plate (1), thereby reducing the number of parts to be installed as well as the production expense.

  • Patent number: 6359363
    Abstract: A small commutator motor (1), in particular a blower motor for motor vehicles, has a rotor shaft (2) rotatably mounted in at least one rotor bearing (12) in a motor housing (8, 9). A commutator (18) and an armature winding (21) electrically connected with the commutator (18) are arranged on the rotor shaft (2) so as to be fixed with respect to rotation relative to it. Further, brush guides (11) for receiving brushes (16) held in sliding contact at the commutator (18) and an end shield (10) which fixes the first rotor bearing (12) in place are provided. The end shield (10) and the brush guides (11) are formed as a one-piece structural component part which is a component part of the motor housing (8, 9) as a first motor housing part (8).

  • Patent number: 6008557
    Abstract: A bearing for a driving shaft of an electrical machine is lubricated by a lubricant. Located between the bearing and rotating parts arranged on the driving shaft is a seal element for lubricant emerging from the bearing. The seal element is configured in the form of a slinger disk by which lubricant emerging from the bearing is returned to the bearing, thus resulting in a closed lubricant circulation. The slinger disk is produced entirely from an elastic material. Lubricant sent off from the slinger disk is returned directly to the bearing.
