Problems solved by technology

Therefore, if it is intended to be compatible with all models, the number of changes in the relative angular positions of the fixing jigs in each assembly device will increase, and it will take time to prepare, and the efficiency will not be high.

no. 1 approach

[0043] like figure 1 As shown, the rotary electric machine 1 of the first embodiment is used for the purpose of transmitting power to the rack and pinion 50 as a steering assist torque motor of an electric power steering apparatus, for example. like figure 2 As shown, the torque of the rotary electric machine 1 in the rack-and-pinion drive device 21 is transmitted from the small-diameter pulley 17 fixed to the shaft 63 included in the rotary electric machine 1 to the large-diameter belt provided on the rack shaft (not shown) via the belt 16 wheel.

[0044] The aforementioned small-diameter pulley 17 , belt 16 , large-diameter pulley, rack and pinion 50 , and the like are accommodated in the gear housing 11 . like figure 1 as well as figure 2 As shown, the gear housing 11 has a rotating electrical machine mounting portion 12 . In addition, the housing 30 of the rotating electrical machine 1 has the gear mounting portion 3 . The gear mounting portion 3 corresponds to an ...

no. 2 approach

[0084] In the second embodiment, as Figure 19 As shown, the gear mounting portion 57 of the rotating electrical machine 28 has a double-sided width portion 65 formed of a pair of flat surfaces 29 parallel to the radial direction of the cylindrical portion 32 . The double-sided width portion 65 can be used as a chuck until the housing positioning hole 5 is machined. In addition, by using the double-sided width portion 65 in common regardless of the model of the rotating electrical machine, the jig for fixing the housing 30 can be shared among the models in the manufacturing process.

Abstract

The invention relates to a rotating electrical machine. The housing (30) has a bottomed cylindrical shape. The stator (40) is fixed to a stator housing section (31) provided on the inner wall of the cylinder section (32) of the housing (30) at an arbitrary relative angular position around the axis of the cylinder section (32). The heat sink (20) is fixed to a heat sink fixing part (33) provided on the inner wall of the cylinder part (32) at an arbitrary relative angular position around the axis of the cylinder part (32). The control unit (10) has a connector unit (2) for external connection, and controls energization of the stator (40). The external mounting portion (3) is a part of a bottom portion (34) of the housing (30) and is integrally formed with the housing (30). The shell positioning holes (5) are formed in the bottom (34) of the shell (30) and located on the circumference concentric with the cylinder part (32) at equal intervals.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application is based on the priority of Patent Application No. 2019-195785 filed on October 29, 2019, and the content of the description is incorporated herein by reference. technical field [0003] The present disclosure relates to rotating electrical machines. Background technique [0004] The allowable space for mounting the rotating electrical machine varies depending on the form of the external device to which the rotating electrical machine is mounted. Therefore, it is desirable to reduce the protruding portion as much as possible, and also to provide a degree of freedom in the relative angle between the external mounting portion of the housing as the protruding portion and the connector around the axis. [0005] For example, Patent Document 1 describes a rotary electric machine in which an external mounting portion and a cylindrical portion of a casing are integrally formed. In addition, in Patent Document...
