Embodiment Construction

[0041] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. This embodiment is an example, and those skilled in the art to which the present invention belongs can realize it in different forms. Therefore, it is not limited to the embodiments described here.

[0042] figure 1 is a cross-sectional view of a traction engine using a bearing-supported rotating shaft according to an embodiment of the present invention.

[0043] As shown in the figure, the traction engine includes a stator assembly 2 arranged in the casing 1, and a rotor assembly 3 surrounded by the stator assembly 2 and having a rotating shaft 31; the left and right sides of the rotating shaft 31 have a pair of supports 10, 20 to support the rotating shaft 31.

[0044] The pair of supporting parts 10, 20 are divided into supporting the left side ( figure 1 ) of the load side support part 10; the support is located on the right side of the opposite ...

Abstract

The invention relates to a traction motor which uses an anti-load side supporting part (20), a supporting part of one side of a rotary shaft (31), as a reference site to fix the rotary shaft (31). Therefore, even if the rotary direction of the motor is changed, the rotary shaft (31) does not move back and forth, thereby greatly reducing noise and vibration of the motor. A load side supporting part (10) used as a supporting part of the opposite side can support thermal expansion movement of the rotary shaft (31), so that the rotary shaft (31) can realize the thermal expansion movement even if an end gap (G) considering the thermal expansion of the rotary shaft is not formed.

Description

technical field [0001] The present invention relates to a traction engine, which is characterized by the use of bearings that can support the rotating shaft; it not only reduces noise and vibration, but also prevents problems such as deterioration of durability, so that it can improve quality. Background technique [0002] A general hybrid car will have a traction engine (Traction Motor) that can drive the rear wheels together with the engine. [0003] The traction engine is a generator that relies on the engine to charge the battery; then the rear wheels are driven through the propulsion shaft connected to the generator and the same power transmission path. This mode of operation is generally referred to as normal mode (Normal Mode). [0004] The traction engine is also the same as the ordinary engine, including the rotor assembly as the rotating part in the casing and the stator assembly as the fixed part. The rotor assembly uses a rotating shaft with a bearing support st...
