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 suitable for the field of motors, and discloses a commutator and a motor. The commutator comprises a commutator body and a positioning protrusion structure, wherein the positioning protrusion structure is convexly arranged at one axial end of the commutator body and is used for axially positioning a first bearing; the commutator body comprises a commutating sheet and a molded part; the molded part is molded at the inner side of the commutating sheet in an injection manner; and the positioning protrusion structure is fixed at the end part, toward the first bearing, of the molded part. The positioning protrusion structure is additionally arranged on the commutator body, so that the axial positioning effect on the first bearing is realized; and the displacement phenomenon of the first bearing is prevented. The positioning protrusion structure is fixed at the end part of the molded part, so that the support coordination relationship between the positioning protrusion structure and a rotating shaft does not need to be specially designed; the problems of great installation difficulty and low installation efficiency of the commutator due to the fact that the positioning protrusion structure and the rotating shaft are in over-tight fit are avoided; and meanwhile, the problems of vibration and abnormal noise generated by the motor in the running process due to the fact that the positioning protrusion structure and the rotating shaft are fitted too loosely 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] like 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 pro...
