Problems solved by technology

This leads to increased wear of the motor, especially the commutation system, which shortens the service life of the motor
The favorable vibration characteristics of helical teeth are opposed to the deterioration of efficiency and higher design costs

Embodiment Construction

[0030] figure 1 The starter device 10 is shown in longitudinal section. The starter device 10 has, for example, a starter motor 13 and a pre-engagement actuator 16 (eg relay, starter relay). The starter motor 13 and the electric pre-engagement actuator 16 are fastened to a common drive end bearing shield 19 . The starter motor 13 is functionally used when the starter pinion 22 is engaged to figure 1 The ring gear 25 of the internal combustion engine, not shown, drives the starter pinion 22 in the center. The starter motor 13 has a pole tube 28 as a housing, which supports on its inner circumference a plurality of pole shoes 31 , which are each wound by a field winding 34 . For starters of smaller power classes, permanent magnets are also conceivable here instead of pole pieces 31 and field winding 34 . The pole piece 31 in turn encloses an armature 37 which has an armature lamination stack 43 consisting of laminations 40 and an armature winding 49 arranged in a plurality o...

Abstract

The invention relates to an electric machine, in particular a starter device (10) for an internal combustion engine. The electric machine comprises a noise-optimized toothing system (232, 234) of two gearwheels (22, 25) which can be brought into engagement with one another. The noise-optimized toothing system (232, 234) is configured as an extra-deep toothing system on at least one of the gearwheels (22, 25). The extra-deep toothing system has an asymmetrical toothing profile (214).

Description

technical field [0001] The invention relates to a noise-optimized toothing. Background technique [0002] DE 10 2008 042 434.5 relates to a retarder and a starter for an internal combustion engine. By means of this reduction gear, a speed-reducing coupling between the drive shaft and the output shaft is achieved by means of at least two mutually engaging gear wheels. The gears are designed as straight teeth, wherein the toothing between the two gears is designed as high teeth. The toothing is realized as a high-tooth configuration, which significantly increases the degree of contact of the toothing elements engaging with each other. A high tooth is a toothing in which the toothing has a degree of overlap ≥ 2.0 by reducing the normal meshing angle, and preferably keeping this normal meshing angle smaller than 20°. In the design of the toothing as a high toothing, the result is a steeper tooth flank, a greater degree of tooth contact and less radial forces occurring on the ...
