AI Technical Summary

Technical Problem

The existing bearing box breathing cap is prone to clogging when high-temperature oil and gas condense, and it is easy to drop debris into the bearing box when refueling, causing lubricating oil to deteriorate.

Method used

A removable bearing box breathing cap is designed, including a disassembled part and an oil storage part. The two parts are connected by a clamp and a clamp slot to form a cooling chamber, and an annular oil storage tank is provided in the oil storage part, and the oil storage tank is connected to the outside to form an oil and gas channel.

Benefits of technology

The disassembly design prevents the top debris from falling into it, and the oil storage tank is regularly cleaned to keep the outside of the breathing cap clean, solving the problem of oil and gas condensation and blockage, and improving the stability of lubricating oil.

Abstract

The detachable bearing box breathing cap comprises an upper part and a lower part, the upper part is a detachable part, the lower part is an oil storage part, the detachable part and the oil storage part are each of a hollow structure, a cooling cavity is formed in the detachable part and the oil storage part when the detachable part and the oil storage part are connected, a clamping block is arranged at the lower end of the detachable part, and a clamping groove is formed in the upper end of the oil storage part. A threaded hole is formed in the lower end of the oil storage part, and an annular oil storage groove is formed in the inner wall of the oil storage part. According to the detachable bearing box breathing cap disclosed by the invention, the problems that high-temperature oil gas is easy to condense and block at the breathing cap and impurities on the top of the bearing box and the breathing cap are easy to fall into the bearing box during oiling to cause deterioration of lubricating oil are solved.
