Problems solved by technology

At present, steel ball type venting plugs are generally used. The venting holes of the venting plug are small and easy to block. When the reducer box is tilted, the lubricating oil will leak through the venting holes of the venting plug, which will easily cause the reducer to malfunction. It will damage the reducer; and because the vent hole is close to the lubricating oil surface, it is easy for the lubricating oil to splash into the vent hole, resulting in oil spray

Abstract

The invention relates to an air filter for a reducer, which comprises an upper cover body and a lower cover body, wherein the inner wall surface of the end portion of the upper cover body abuts against the outer wall surface of the lower cover body to form an enclosed cavity, a device inside the cavity is glued with the upper cover body to form a filter paper fixing frame, and filter paper is arranged on the filter paper fixing frame. Ventilating holes and ventilating grooves are distributed on the lower cover body in annular mode. The lower cover body is in thread connection with a ventilating seat, the thickness of the middle wall of the ventilating seat is thickened outwards to form an annular stair, and a first sealing ring and a second sealing ring are respectively arranged on the upper portion and the lower portion of the annular stair. The air filter for the reducer has the advantages of being easy and convenient to install, large in ventilating quantity and not apt to block.

Description

technical field [0001] The invention relates to the field of reducers, in particular to an air filter for a reducer. Background technique [0002] The main function of the vent plug is to discharge the gas generated during the operation of the gearbox in time. At present, steel ball type venting plugs are generally used. The venting holes of the venting plug are small and easy to block. When the reducer box is tilted, the lubricating oil will leak through the venting holes of the venting plug, which will easily cause the reducer to malfunction. It will damage the reducer; and because the air hole is close to the oil surface of the lubricating oil, it is easy for the lubricating oil to splash into the air hole, resulting in oil injection. Contents of the invention [0003] In view of the above shortcomings, the applicant provides an air filter for a reducer, which has the advantages of simple and convenient installation, large air flow, and is not easy to be blocked. ...
