Patent number: 6520708Abstract: 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.Type: GrantFiled: November 24, 2000Date of Patent: February 18, 2003Assignee: Robert Bosch GmbHInventors: Oliver Jung, Hartmut Nitzsche, Heinz Seibert, Gerald Kuenzel, Hans-Peter Seebacher, Bernd Wieland, Peter Litterst, Hansjuergen Linde, Uwe Neumann

Publication number: 20020121836Abstract: 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.Type: ApplicationFiled: April 9, 2002Publication date: September 5, 2002Inventors: Wolfgang Winkler, Gerhard Gross, Hartmut Nitzsche, Bernhard Merschroth, andreas Ewert

Patent number: 6359363Abstract: 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).Type: GrantFiled: March 17, 2000Date of Patent: March 19, 2002Assignee: Robert Bosch GmbHInventors: Josef Foerstera, Hartmut Nitzsche, Bernhard Merschroth, Detlef Prahl, Michael Hermann

Patent number: 6008557Abstract: 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.Type: GrantFiled: July 16, 1998Date of Patent: December 28, 1999Assignee: Robert Bosch GmbHInventors: Gerd Dornhoefer, Hartmut Nitzsche, Bernd Wieland
