Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0022] The invention provides a motor sealing ring structure, such as figure 1 As shown, it includes a sealing ring body 1 and a fixing structure and a waterproof structure arranged thereon. The first end of the sealing ring body 1 is pierced through the end cover 2 to abut against the bearing. The fixing structure can define the sealing ring body 1 degree of freedom relative to the rotating shaft, the waterproof structure can prevent water from entering the mo...

Abstract

The invention provides a motor sealing ring structure and a motor with the same, relates to the technical field of sealing rings, and solves the technical problem of tedious sealing ring installationprocess in the prior art. The motor sealing ring structure comprises a sealing ring body, and a fixing structure and a waterproof structure that are arranged on the sealing ring body; the first end ofthe sealing ring body penetrates through the end cover and abuts against a bearing. The fixing structure can limit the degree of freedom of the sealing ring body relative to a rotating shaft; the waterproof structure can prevent water from entering the motor; the sealing ring body can penetrate through the motor end cover from the outside to be installed after the motor is integrally installed, the fixing structure and the waterproof structure are both arranged on the sealing ring body and can be integrally installed, and the problem that the installation process of an existing sealing ring is complex is solved.

Description

technical field [0001] The invention relates to the technical field of sealing rings, in particular to a motor sealing ring structure and a motor with the same. Background technique [0002] At present, during the production and assembly of electric vehicle motors, the bearing is first pressed into the lower end cover, and then the sealing ring is nested on the bottom wall of the bearing chamber, and the fan blade is installed on the shaft head with a fixing card. The installation process is cumbersome and there are missing parts. Second, the shaft head of the motor shaft is exposed and easy to rust; in order to prevent rainwater from entering the gap between the shaft head and the end cover and the bearings and internal components, fan blades will be installed on the shaft head. The rotation prevents rainwater from invading the motor, but the distance between the fan blade and the sealing ring next to the bearing is large, at least the shaft head is vulnerable to rainwater ...
