Embodiment Construction

[0035] figure 1 An electric machine 100 in the form of a starter or starter motor is shown in section with a relay 42 arranged as a switching relay or switching relay. The starter housing 10 of the starting device comprises a cylindrical housing part 11 and a housing cover or housing cover 13 which are connected to each other by screws (not shown). The cylindrical housing part 11 is closed at the rear by said cover 13 . In the central area of ​​the cover 13 is formed a hub or (drive) collar 121 directed towards the outside of the starter. A bearing region is formed on the inside of the collar 121 , in which the armature shaft of the electric starter motor 18 , the rotor shaft or the rear end 17 a of the drive shaft 17 is supported. The armature of the electric starter motor 18 is identified with the reference numeral 19 . Radially outside the armature 19 , a plurality of (permanent) magnets 20 of the electric starter motor 18 are arranged on the wall of said housing part 11...

Abstract

The object of the invention relates to a method for manufacturing and / or mounting an electrical machine (100) and an electrical machine (100), in particular a starting mechanism as a starter, for starting a combustion engine, comprising an armature shaft (17), which is at one end floating mounted in an commutator bearing, comprising the steps: moving an armature shaft section (17b), defined by an armature shaft shoulder (117b), into the commutator bearing, so that said armature shaft section (17b) at least partly protrudes from the commutator bearing wherein an abutment device (130) is arranged at and / or on said armature shaft section (17b) and is abutted against one side of the commutator bearing and said armature shaft (17) is moved against and relatively to said abutment device (13), until a desired axial play (AP) between said armature shaft shoulder (117b) and said commutator bearing is reached.

Description

technical field [0001] The invention relates to a method for producing and / or assembling an electric machine, in particular a starter mechanism for starting an internal combustion engine, comprising an armature shaft mounted floating at one end on a commutator In a commutator bearing, the method includes the steps of moving an armature shaft section defined by an armature shaft shoulder into a commutator bearing such that the armature shaft section extends at least partially from the commutator bearing It is noted that a bearing device is arranged at and / or on the armature shaft section, and the bearing device abuts on one side of the commutator bearing. [0002] Furthermore, the invention relates to an electric machine, in particular a starter mechanism for starting an internal combustion engine as a starter, said electric machine comprising an armature shaft mounted floating at one end in a commutator bearing, said The armature shaft includes at least one armature shaft sec...
