A leak-proof device for a thin oil lubricated bearing seat

Abstract

The invention provides a leakage-proof technology of a thin oil lubrication bearing seat. The leakage-proof technology comprises a roller, a bearing seat, a rubber sealing ring, an external water seal, a fixed end cover, a spacer ring, compressed gas, lubricating grease and one set of leakage-proof technology; the technology is characterized in that a gap of a combination part of the roller and the bearing seat is in positive pressure all the time when the roller rotates; a sealing technology of the bearing seat is improved, and the dry and clean compressed gas is introduced to the gap of thecombination part of the roller and the bearing seat; the position is located between the water seal and an oil seal, and a gap between the water seal of the bearing seat and an oil seal is at a micro-positive pressure gas sealing state, so that rolling oil can be prevented from entering the bearing seat and the lubricating grease is prevented from being leaked out from the bearing seat. Compared with the prior art, the leakage-proof technology can be used for preventing the rolling oil from entering the bearings eat and also can be used for preventing the lubricating grease from being leaked out from the bearing seat; the consumption amount of compressed air is small, the cost investment of improvement is small and an applicable range is wide.

Description

technical field [0001] The invention relates to a thin oil lubricated bearing seat technology, in particular to a thin oil lubricated bearing seat leakage prevention device. Background technique [0002] At present, thin oil centralized lubrication technology has been widely used in the steel rolling industry due to its many advantages, especially in the lubrication of roll bearings, but it has two disadvantages: 1. Oil leakage problem: rolls (including backup rolls, intermediate rolls, working rolls, etc.) Oil leakage of bearing housings is a common problem. On the one hand, a large amount of oil leakage will greatly increase the cost, and on the other hand, it will cause serious pollution to the roll lubrication system and affect the normal use of rolling fluid; 2. Water inflow: that is, rolling When the liquid / cooling water enters the roll bearing housing, a large amount of water inflow will cause the emulsification of the lubricating oil, reducing its lubricating perform...
