Embodiment Construction

[0018] Refer below figure 1 and 2 A motor according to a first preferred embodiment of the present invention will be described in detail.

[0019] figure 1 A partial sectional view of an electric machine 1 is shown with a housing 2, a shaft 3 and a rolling bearing 4 with an inner ring 5, an outer ring 6 and a plurality of rolling bodies 7, of which only visible in the sectional view Two rolling elements 7 have been produced. The outer ring 6 of the rolling bearing 4 resting on the housing bottom 9 of the housing end region 8 of the housing 2 is fixed by means of first and second welded connections 10 , 11 arranged in parallel on the housing 2 that run all the way around. The rolling bearing 4 thus forms the floating bearing of the electric machine 1 , the outer ring 6 of which is fastened to the housing 2 and the inner ring 5 of which supports the shaft 3 in a rotatable manner. Alternatively, a design as a fixed bearing can also be provided, in which the inner ring 5 is ad...

Abstract

The invention relates to a motor, which comprises a housing (2), a shaft (3) and a rolling bearing (4) for bearing axial force. A welding connection is provided between the rolling bearing (4) and the housing (2) and / or between the rolling bearing (4) and the shaft (3).

Description

technical field [0001] The invention relates to an electric machine. Background technique [0002] In the prior art, conventional rolling bearings are used in permanently excited electric machines for transmitting axial forces, which are fastened axially on the shaft and / or in the housing with a positive or non-positive fit. Conventional connection types require either cumbersome process steps that lengthen or interrupt the production sequence or additional components that increase the number of process steps and increase the manufacturing costs. Contents of the invention [0003] The electric machine according to the invention has the comparative advantage that a welded connection is produced between the rolling bearing and the housing and / or a welded connection is formed between the rolling bearing and the shaft. In this way, a cost-effective connection can be formed in a simple manner between the outer or inner rolling bearing ring and the housing or the shaft of the e...
