Embodiment Construction

[0021] figure 1 The electric machine 10 in the form of a starter is shown in longitudinal section. This starting device has a starter motor 13 and a pre-engagement actuator 16 (for example a relay or starter relay). The starter motor 13 and the electric pre-engagement actuator 16 are fastened to the same drive bearing cover 19 . The starter motor 13 is functionally used to drive the starter pinion 22 when the starter pinion engages a ring gear 25 of the internal combustion engine, not shown here.

[0022] The starter motor 13 has a housing 26 which has a pole tube 28 which supports a pole 31 on its inner circumference. The stator 29 is thus formed. The poles 31 in turn surround a rotor 37 (armature) which has an armature pack 43 made of laminations and an armature winding arranged in slots. A commutator 52 is also provided at the end of the drive shaft 44 facing away from the starter pinion 22 . During operation, the commutator 52 or its commutator segments 55 are powered...

Abstract

The invention relates to an electric machine, in particular starting device, and a method for producing a support bearing assembly of an electric machine. The electric machine (10), in particular starting device, has a stator (29), and a rotor (37) which is equipped with a drive shaft and which is arranged radially in an inner side of the stator (29). Support bearing arrangements (66,69) are arranged on a rotating-axial side of the rotor. The arrangement causes bearing forces (Fa, Fr) in radial and rotating-axial direction, and arranged in a bearing cover (60). The arrangement supports a drive shaft (44), and a screw element (91) is held in a retaining thread (94) of the bearing cover by a screw-in thread. The screw element causes radial bearing force and axial bearing force. A cavity i.e. blind hole, is formed in the screw element. An independent claim is also included for a method for manufacturing support bearing arrangement of an electrical machine.

Description

technical field [0001] The invention relates to an electric machine, in particular a starter, and a method for producing an end bearing arrangement of an electric machine. Background technique [0002] An electric motor in the form of a starter is known from German publication DE3216448A1. A device of this type is disclosed, by means of which the so-called axial play of the rotor of the electric drive can be adjusted to a desired level by means of an adjusting screw. A disadvantage of this solution is that the end bearing arrangement is relatively long in the axial direction. Contents of the invention [0003] It is therefore the object of the invention to realize an axially shorter end bearing arrangement. [0004] To this end, according to the characteristic provisions of the first independent claim, the end bearing arranged in the bearing cover, which supports the rotor shaft here, is held in the receiving thread of the bearing cover by means of a screw element by scr...
