Problems solved by technology

However, high torques cannot or cannot be reliably transmitted by means of such press-fitted components
Thus, eg EP 2 264 872 A1 or US Pat. No. 6,493,923 B1 disclose a cylindrical shaft on which several parts are arranged by means of a press fit, but which are not suitable for reliable transmission of torque, especially large torque

Embodiment Construction

[0032] figure 1 The internal combustion engine electric machine 100 , which is designed as a starting device, is shown in cross section with a relay 42 which is also embodied as a switching relay or switching relay. The housing 10 of the electric machine 100 comprises a cylindrical housing part 11 and a housing 13 , which are connected to each other by screws, not shown in detail. The cylindrical housing part 11 is closed at the rear by a casing 13 , in the middle part of which the outwardly pointing hub is molded. In the hub is a journal in which the rear end 17 a of the armature shaft 17 of an electric starter motor 18 , the armature of which is designated by reference numeral 19 , is supported. Radially outside the armature 19 there are a plurality of (permanent) magnets 28 of the starter motor 18 on the wall of the housing part 11 . The front end of the armature shaft 17 is supported with an end section 22 of the same diameter in a coaxially extending blind hole 23 , not...

Abstract

The invention relates to a method for producing and / or operating an electric machine (100) for starting an internal combustion engine, as well as the electric machine (100), in particular a starting device such as a starter motor, the electric machine comprising a transmission with an armature shaft (17) Chain, on which at least one transmission mechanism (130) is arranged non-rotatably relative to the armature shaft (17), wherein at least one transmission element (135) of the transmission mechanism (130) is directly non-rotatable relative to the armature shaft Arranged on the armature shaft (17) and the other transmission element (136) of the transmission mechanism (130) is arranged non-rotatably on the at least one transmission element (135) arranged non-rotatably on the armature shaft (17) .

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for producing and / or operating an electric machine for starting an internal combustion engine, in particular a starting device such as a starter. [0002] The invention also relates to an electric machine for starting an internal combustion engine according to the preamble of claim 5 , in particular a starting device as a starter. Background technique [0003] The invention is based on a system with a starter or starter motor of the type described in the independent claims. [0004] The subject matter of the invention is a starter and a starter for a vehicle having an internal combustion engine with an electric machine comprising an armature and a commutator, wherein the armature has an armature shaft with a pinion arranged thereon. [0005] The prior art already discloses starters with a starter relay for vehicles with an internal combustion engine, which starters generally includ...
