Closed screening system of rotary support of pneumatic motor

Abstract

The invention discloses a closed screening system of a rotary support of a pneumatic motor. Screening plate equipment comprises an inner ring frame body and an outer ring frame body; the screening plate equipment is hooped on a roller body by the inner ring frame body, and is contacted with the inner surface of an antirust hole by the outer ring frame body; a screening plate is fixedly connected between the inner ring frame body and the outer ring frame body, so that particle impurities flowing from one end of the antirust hole are directly isolated by the screening plate, and antirust liquidin the antirust hole is conveyed to a closing part by the screening plate in real time; and the inner ring frame body and the outer ring frame body are both of plastic block structures. The problems of damage of the rotary support caused by flowing of the particle impurities into the antirust hole and the rotary support and frequent falling of bronze wire at the end from a frame body blockage bodyplacing hole into the rotary support in the prior art are prevented.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a closed screening system for a slewing bearing of an air motor. Background technique [0002] The air motor is equipped with a roller body, which is arranged in the antirust hole of the support table or support plate for placing the slewing bearing through the slewing bearing. Anti-rust liquid, with a sealing device such as a customized rubber ring to seal the gap between the roller body and the anti-rust hole to prevent the anti-rust liquid in the anti-rust hole from flowing out. [0003] However, because the power of the air motor varies greatly and the surrounding conditions are not good, after the rubber ring is frequently damaged, the particles and impurities rush into the anti-rust holes and the slewing bearing, resulting in the destruction of the slewing bearing. However, the existing air motor is equipped with a frame plugging body equipped with end glass bro...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a closed screening system for the slewing bearing of the air motor, which avoids the destruction of the slewing bearing caused by the influx of particles and impurities into the anti-rust hole and the slewing bearing in the prior art, and the glass bronze wire at the end often passes through The problem that the frame blocking body falls out of the hole and falls into the slewing bearing
