Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0026] It should also be noted that the orientation terms such as left, right, up, down, top, and bottom in the following examples are only relative concepts or refer to the normal use status of the product, and should not be ...

Abstract

The invention is applicable to the field of electric motors, and discloses a commutator and a motor, wherein the commutator includes a commutator body and a positioning device protruding from one end of the commutator body in the axial direction for axial positioning with the first bearing The protruding structure, the commutator body includes a commutator piece and a molded part injection-molded inside the commutator piece, and the positioning protruding structure is fixed on the end of the molded part facing the first bearing. The present invention realizes the axial positioning effect of the first bearing by adding a positioning protrusion structure on the commutator body, and prevents the first bearing from being displaced. Since the positioning protruding structure is fixed on the end of the molded part, there is no need to specially design the supporting relationship between the positioning protruding structure and the rotating shaft, which avoids the difficulty in installing the commutator caused by the tight fit between the positioning protruding structure and the rotating shaft The problem of large size and low installation efficiency occurs, and at the same time, the problems of vibration and abnormal sound caused by the loose fit between the positioning protrusion structure and the rotating shaft are avoided.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a commutator and a motor with the commutator. Background technique [0002] In a traditional motor with a commutator, there is no positioning structure such as a shaft shoulder or a collar for positioning the bearing between the commutator and the bearing on its side, so that the bearings on the side of the commutator It is prone to displacement, which seriously affects the performance of the motor. [0003] Such as Figure 5 As shown, in order to solve the above problems, the prior art proposes a scheme of adding a positioning sleeve 6' between the commutator 1' and the bearing 2'. Although this scheme effectively prevents the displacement of the bearing 2', the , which also poses the following problems: [0004] 1) The number of components of the motor is increased, and the structural complexity of the motor is increased; and in the manufacturing process of the motor, the manufacturing ...
