Embodiment Construction

[0053] FIG. 1 shows a housing blank 1 for a housing 7 (see FIG. 2 ) of an electric machine 100 . The housing blank 1 is made approximately cylindrical. And it has an inner cavity 10 made approximately cylindrical. The fixing piece 13 extends into the inner cavity 10 . The housing blank 1 , the interior space 10 and the fastening plate 13 are arranged concentrically around the axis 4 . The housing blank 1 extends in an axial direction 41 .

[0054] Fastening tabs 13 are provided for arranging the injection molded part 5 formed from the curable compound 5 (see FIG. 2 ). The injection molded part 5 is provided for forming the bearing 6 (see FIG. 2 ) for the shaft 40 (see FIG. 8( b )) of the motor 100 (see FIG. 8( b )). The shaft 40 extends in an axial direction 41 . The hardened curable compound 5 forms the injection molded part 5 . Therefore, the terms curable mass and injection molded part are used synonymously below.

[0055] A tool (not shown) is required in order to f...

Abstract

The invention relates to a housing used for a motor. The housing comprises a housing blank, which is extended around an axis concentrically, and is provided with an inner cavity. The housing blank is also provided with a fixed sheet, which is extended to the inner cavity. The fixed sheet is provided with an injection molding member, and a bearing is formed in the injection molding member. The invention also relates to a bearing cover used for a motor. The bearing cover is provided with a bearing formed in the injection molding member. The invention also relates to a motor provided with the housing and / or the bearing cover, and an adjustable driving device provided with the motor.

Description

technical field [0001] The invention relates to a housing for an electric machine comprising a housing blank extending concentrically around an axis. Furthermore, the invention relates to a bearing shield for an electric machine, which extends concentrically around an axis. Furthermore, the invention relates to an electric motor with such a housing and / or bearing shield, and to an adjustable drive with such an electric motor. Background technique [0002] The electric machine has a rotating part which is mounted in the stationary component, for example by means of ball bearings or sliding bearings. Noise and vibration occur in its rotation, and the greater the concentricity deviation of the rotating part from the rotation axis, the greater the noise and vibration. The bearings of such electric machines are usually fixed in the surrounding housing or on the housing cover, for example by gluing. [0003] For electrical machines whose stators are axially longer than their ro...
