Embodiment 1

[0035] figure 1 It is a perspective view showing the rotating electric machine in the first embodiment of the present invention, figure 2 It is a figure which shows the rotating electric machine in the 1st Example of this invention, (a) is a structural view, (b) is an assembly view.

[0036] exist figure 1 , 2 Among them, 21 is the stator, 26 is the rotating shaft, 27 is the bolt, 28 is the fixed platform, 31a is the rear bracket, 32a is the supporting platform, 33 is the joint, 34 is the rear bearing, 35 is the load side bearing, L3 is the said The axial length of the support stand 32a.

[0037] On the load side of the stator 21, a load side bearing 35 and a support platform 32a are fixed by bolts 27, and a rear bearing 34 and a rear bracket 31a are fixed by bolts 27 on the rear side, and the rear bracket 31a is passed through a joint 33 It is fixed on the support table 32a. Here, the support stand 32a has an axial length of L3 and also serves as a load-side bracket. ...

Embodiment 2

[0042] Figure 4 It is a figure which shows the rotating electric machine in the 2nd Example of this invention, (a) is a structural view, (b) is an assembly view.

[0043] exist Figure 4Among them, a support stand 32b is fixed to the load side of the stator 21, and a rear bracket 31a is fixed to the rear side of the stator. Here, the support stand 32b is formed in the shape in which the support stand 32a and the joint 33 in Embodiment 1 are integrated, and the joint portion 40 is provided at the position where the rear bracket 31a is fixed, and the support stand 32b is supported by The table 32a and the joint 33 are produced by welding, cutting using an NC machine tool, or casting.

[0044] In this way, the number of parts can be further reduced, and the assembly time can be shortened.

Embodiment 3

[0046] Figure 5 It is a figure which shows the rotating electric machine in the 3rd embodiment of this invention, (a) is a structural view, (b) is an assembly view.

[0047] exist Figure 5 Among them, a support stand 32a is fixed to the load side of the stator 21, and a rear bracket 31b is fixed to the rear side. Here, the rear bracket 31b is formed in a shape in which the rear bracket 31a and the joint 33 in Embodiment 1 are integrated, and a joint portion 41 is provided at a position fixed to the support table 32a. 31b is produced by welding the rear bracket 31a and the joint 33, cutting using an NC machine tool, or casting.

[0048] In this way, the bolts used to fix the rear bracket 31b are concentrated on one side, so that the tool cannot be entered due to the interference between the lower part of the rear bracket 31b and the fixing table, or the tool can only be rotated at a small angle. And other issues. As a result, not only at the time of assembly but also at t...

Abstract

To provide a dynamo-electric machine which can downsize and lighten parts and a device without transforming even if downward load adds to a rotating shaft, and can shorten its installation length, and can shorten its assembly time, and can facilitate the removal and attachment work of a bracket on an anti-load side. The bracket on an anti-load side is fixed to a supporting stand by a joint. The supporting stand is provided with a mating part and the bracket on an anti-load side is fixed to it. The bracket on an anti-load side is provided with a mating part, and is fixed to the supporting stand. The supporting stand and the bracket on an anti-load side are provided with mating parts in their opposed sections, whereby both are fixed.

Description

technical field [0001] The present invention relates to a rotating electric machine used as a generator, a motor, etc., and particularly relates to the structure of a traction machine for an elevator. Background technique [0002] Figure 7 It is a perspective view showing the rotating electric machine in the first prior art. [0003] exist Figure 7 Among them, 21 is a stator, 22 is a rear bracket, 23 is a rear support platform, 24 is a load side support platform, 25 is an integral support platform, 26 is a rotating shaft, 27 is a bolt, and 28 is a fixed platform. [0004] On the load side of the stator 21 (the direction in which the rotating shaft 26 protrudes and applies a load), a load-side support stand 24 is fixed, and on the rear side (the direction opposite to the load side), a rear support stand 23 is fixed. 24 and the rear support platform 23 are fixed on an integral support platform 25 which is mounted on a fixed platform 28 . In particular, in an elevator tract...
