A transition sleeve of a stepped ring lubricating bearing and its oil supply plate

Abstract

A stepped under-ring lubricating bearing transition sleeve is arranged on a rotating shaft in a sleeving mode and comprises a sleeve body used for being arranged on a bearing in a sleeving mode. The outer wall of the sleeve body is of a three-step structure, and the steps are sequentially arranged as the first step, the second step and the third step with the heights gradually reduced. The bearing is sleeved with the second step, an end cover is fixedly connected to the end, close to the first step, of the sleeve body, and a round oil collecting hole with the diameter larger than the shaft diameter of the rotating shaft is formed in the middle of the end cover. A U-shaped oil groove is dug in the second step in the circumferential direction of the sleeve body, and a plurality of oil spraying channels are dug in the sleeve body and communicate with the oil collecting hole and the U-shaped oil groove correspondingly. The stepped under-ring lubricating bearing transition sleeve is simple in structure, stress concentration cannot be caused in installation, damage to the shaft can be avoided, the splashing direction of lubricating oil can be controlled, and the flowing speed and the recovery rate of the lubricating oil can be increased.

Description

technical field [0001] The invention relates to a lubricating device under a bearing ring, in particular to a transition sleeve for a stepped lubricating bearing under the ring and an oil supply plate thereof. Background technique [0002] Large-diameter high-speed bearings have a high DN value, bear heavy loads, and generate a lot of heat during operation, which will seriously affect the service life of bearings working in high-temperature equipment environments. As far as the bearing is concerned, the key measure to solve its high temperature problem is to adequately lubricate and cool the bearing. In the past, high-speed bearings generally used spraying thin oil lubrication method. This lubrication method is to inject lubricating oil from the end face of the bearing into the gap between the cage and the ring at a certain angle to lubricate the bearing. Under high-speed conditions, affected by factors such as the bearing structure, its lubrication efficiency is low, and i...

AI Technical Summary

Problems solved by technology

However, in the prior art, there has been a lack of an under-ring lubricating device for bearings that is flexible in disassembly and assembly, can be assembled and disassembled without damaging the shaft, and can effectively control the splashing direction of lubricating oil and realize full recovery of lubricating oil.
