A bearing housing for positioning a vertical lifting shaft

Abstract

This utility model discloses a bearing housing for vertical shaft positioning, relating to the technical field of bearing housings. It includes an upper bearing housing, an oil passage, and a one-way connecting pipe. The upper bearing housing has an oil passage inside, and an oil filling hole on its outer wall. The inner wall of the oil filling hole is fitted with a one-way connecting pipe for easy one-way flow. A lower bearing housing is located below the upper bearing housing. Both the upper and lower bearing housings have their inner walls coated with a high-molecular-weight ceramic polymer coating. The device involves inserting an injection pipe into the one-way connecting pipe and pushing a flipping plate to inject lubricating oil into the oil filling hole. After injecting a suitable amount of lubricating oil, the injection pipe can be pulled out of the one-way connecting pipe. Then, the flipping plate, under the elastic force of a torsion spring, is driven to insert into a sliding groove, preventing lubricating oil backflow and achieving one-way delivery. This solves the problem of oil leakage and backflow in the lubrication channel and improves sealing performance.
