Problems solved by technology

[0003] However, the resistance between the apron and the motor is completely provided by mirror friction. The apron can be easily rotated on the motor to change the positioning angle, which leads to many problems in the production line that cause the angle of the apron to change due to human factors, and the motor rotates. Due to inertia and other reasons, it is easy to cause relative rotation between the apron and the motor. After long-term use, there will still be problems with the contact between the outlet bar and the motor gland, which will cause the whole machine to resonate.

Abstract

The invention discloses a motor end cover positioning structure and a motor. The motor end cover positioning structure comprises an end cover body (1) and a rubber ring (2), wherein a mounting bulge (3) is arranged on the end cover body (1); the rubber ring (2) sleeves the mounting bulge (3); the periphery of the rubber ring (2) is provided with a positioning groove or a positioning bulge (4); circumferential concave-convex positioning match is formed between the rubber ring (2) and the end cover body (1); the number of convex parts (5) is smaller than that of concave parts (6); the number of the concave parts (6) is integer multiple of that of the convex parts (5); and the convex parts (5) can be embedded in the concave parts (6) at the same time. According to the motor end cover positioning structure of the invention, relative rotation between the motor and the rubber ring can be effectively avoided, the stability of the motor mounting structure is improved, and the motor noise is reduced.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a motor end cover positioning structure and a motor. Background technique [0002] The lead wires of the plastic-encapsulated motor of the existing air conditioner are led out through the outlet bar, and then connected to the air conditioner control panel after passing through the motor gland. There will be a gap of 5-10mm between the outlet bar and the opening of the motor gland. At this time, due to the inertia of the fan, the motor will be subjected to an opposite force, causing the motor to rotate, and the outlet row will touch the motor gland, which will cause a resonance sound. In order to avoid this problem, most air conditioner manufacturers reserve positioning holes on the frame when designing the air conditioner. The raised rubber ring on the outer wall sleeve of the motor bearing will solve the problem that the motor is prone to rotation when it is started to ...
