Noise insulation dustproofing motor end cover

Abstract

The invention discloses a noise-insulation dustproofing motor end cover. The noise-insulation dustproofing motor end cover comprises an end cover body, a first boss and a second boss are arranged on the left end face and the right end face of the end cover body, a sealing groove is formed in the outer wall of the first boss, and a sealing ring is arranged in the sealing groove, a first counter bore, a second counter bore, a third counter bore, a bearing seat hole and a shaft outlet hole are sequentially and concentrically arranged in the end cover body from left to right, the diameters of thefirst counter bore, the second counter bore, the third counter bore, the bearing seat hole and the shaft outlet hole decrease gradually, the right end face of the end cover body is concentrically provided with a fourth counter bore, a first sound insulation felt is arranged in the third counter bore in a clearance fit mode, a silica gel pad is arranged in the second counter bore in a clearance fitmode, a rubber pad is arranged in the first counter bore in a clearance fit mode, an annular groove is concentrically formed in the bottom surface of the first counter bore, the right end face of therubber pad is provided with a convex ring in interference fit with the annular groove, and a second sound insulation felt and a lip-shaped sealing ring are successively arranged in the fourth counterbore in a clearance fit mode from left to right. The noise can be effectively isolated, the noise pollution is reduced, and the dustproof performance is good.

Description

technical field [0001] The invention relates to the technical field of motor components, in particular to a noise-insulating and dust-proof motor end cover. Background technique [0002] The motor end cover is an important component of the motor. The functions of the motor end cover are: one is to seal the inside of the motor, and the other is to carry the motor bearing. When the motor is running, the bearing often produces some noise, especially for high-speed motors. Especially large, the motor end cover of the prior art has no sound insulation effect, so that the noise pollution of the workshop is serious, and the dustproof performance is poor, which is in urgent need of improvement. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a noise-insulating and dust-proof motor end cover, which has a simple and reasonable structure, can effectively isolate noise, reduce noise p...
