Problems solved by technology

[0006] The use of metal ring gears produced by the sintering process with additional elements made of rubber is expensive on the one hand in terms of the production of the sintered metal and on the other hand in terms of the additional use of elastic elements made of rubber very high
Another disadvantage of elastic elements made of rubber is that the rubber material tends to relax during its service life, so that the elastic properties of the rubber material change slowly but significantly over time

Embodiment Construction

[0022] by basis figure 1 The schematic diagram of the structure and electrical circuit of a starter for an internal combustion engine is known in the diagram.

[0023] by basis figure 1 As can be seen from the illustration in FIG. 2 , a starter 10 for an internal combustion engine has a pinion 12 mounted on an armature shaft of an armature 26 . This pinion can mesh with the ring gear 2 of the internal combustion engine. The meshing of the pinion 12 into the ring gear 14 of the internal combustion engine takes place by means of a clutch lever 18 which is actuated by a starter relay 30 of the starter 10 . A roller freewheel clutch 16 is situated between a coupling lever 18 actuatable via a starter relay 30 and the pinion 12 . Furthermore, an epicyclic gear, in particular a planetary gear 20 , is installed in the starter 10 . The planetary gear 20 generally has the advantage that it has a very compact design while enabling high transmission ratios. Due to the advantageous to...

Abstract

The invention relates to an electrical machine, in particular a starter for internal combustion engines, having a torque support (42, 50, 72) for a transmission component (44) of a planetary gearing (20) on a housing (54, 62). The torque support (42, 50, 72) comprises symmetrically or asymmetrically designed material weakening (64, 70, 74, 84) enabling a dampening.

Description

technical field [0001] The invention relates to an electric machine with integrated damping for transmission components. Background technique [0002] FR2 639,701 relates to a reducer which is a planetary gear transmission. In this solution, the ring gear of the planetary gear is supported in the housing by means of elastic elements. The planetary gear comprises, in addition to the ring gear, at least two planet gears which mesh with the external toothing of the sun gear and with the internal gearing of the ring gear supported by elastic elements. [0003] US 2003 / 0177852 A1 discloses a starter having elastic damping elements for both axial and circumferential vibrations in order to damp vibrations occurring during the starting phase of the starter. The starter according to US 2003 / 0177852 A1 also includes a planetary gear. [0004] DE 43 02854 C1 relates to a starting device for an internal combustion engine. DE 43 02 854 C1 discloses a starter device for an internal co...
