Description
Technical Field
The invention relates to a technology of a thin oil lubrication bearing seat, in particular to a leakage-proof device of a thin oil lubrication bearing seat.
Background
At present, the thin oil centralized lubrication technology is generally applied to the steel rolling industry due to a plurality of advantages, and is particularly widely applied to the lubrication of roller bearings, but the technology has two defects: 1. the problem of oil leakage: the oil leakage of a bearing seat of a roller (comprising a supporting roller, a middle roller and a working roller) is a common problem, and the large amount of oil leakage greatly increases the cost on one hand, and causes serious pollution to a roller lubricating system on the other hand, thereby influencing the normal use of rolling liquid; 2. the problem of water inflow: that is, the rolling liquid/cooling water enters the roll chock, and a large amount of water enters the roll chock, so that the emulsification of the lubricating oil is caused, the lubricating performance of the roll chock is reduced, and the service life of the bearing is greatly reduced due to poor lubrication.
A leakage-proof device for a thin oil lubrication bearing seat is characterized in that compressed air is introduced into a gap between a roller and a bearing seat joint part, the gap between the roller and the bearing seat joint part is always kept in positive pressure when the roller rotates, rolling oil can be prevented from entering the bearing seat, meanwhile, lubricating oil can be prevented from leaking out of the bearing seat, the consumption of the compressed air is low, the investment of improved cost is low, and the application range is wide.
Disclosure of Invention
The invention aims to provide a leakage-proof device for a thin oil lubrication bearing seat, which solves the problems that the traditional thin oil lubrication bearing seat is easy to leak oil and enter water.
In order to solve the technical problem, the invention adopts a thin oil lubrication bearing seat leakage-proof device which 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 a set of leakage-proof device and is characterized in that the gap of the joint of the roller and the bearing seat is always kept in positive pressure when the roller rotates, namely, the dry and clean compressed gas is introduced to the gap of the joint of the roller and the bearing seat and is positioned between the water seal and the oil seal by improving the sealing process of the bearing seat, so that the gap between the water seal and the oil seal of the bearing seat is always in a micro-positive pressure gas seal state, and the rolling oil can be prevented from entering the bearing seat and the lubricating grease can.
Furthermore, a gas seal is added between the water seal and the oil seal, the gas pressure of the gas seal is adjustable, the gas seal pressure is adjusted to be proper in a linkage mode at any time according to the rotating speed of rollers of different rolling mills, the gaps are kept in a micro positive pressure state all the time, the oil/water infiltration on the two sides can be sealed, and the gas consumption is low.
Furthermore, the fixed end cover is arranged above the spacer ring, rubber sealing rings are arranged on two sides of the spacer ring, a concave portion is arranged in the middle of the spacer ring, compressed gas can be placed in the concave portion to form a gas seal, and lubricating grease is arranged between the rubber sealing rings and the bearing seat.
Compared with the prior art, the leakage-proof device for the thin oil lubrication bearing block, disclosed by the invention, has the advantages that compressed air is introduced to the gap of the joint of the roller and the bearing block, the gap of the joint of the roller and the bearing block is always kept in positive pressure when the roller rotates, rolling oil can be prevented from entering the bearing block, lubricating oil can be prevented from leaking out of the bearing block, the consumption of the compressed air is low, the improvement cost investment is low, and the application range is wide.

Detailed Description
In the preferred embodiment of the present invention, in order to solve the above technical problems, the present invention adopts a thin oil lubrication bearing seat leakage prevention device, which comprises a roller 1, a bearing seat 2, a rubber seal ring 3, an external water seal 4, a fixed end cover 5, a spacer ring 6, a compressed gas 7, a lubricating grease 8 and a set of leakage prevention devices, and is characterized in that a gap between the roller 1 and the bearing seat 2 is always kept at a positive pressure when the roller 1 rotates, that is, by improving the sealing process of the bearing seat 2, the dry and clean compressed gas 7 is introduced to the gap between the roller 1 and the bearing seat 2, and the position is located between the water seal and the oil seal, so that the gap between the water seal and the oil seal of the bearing seat 2 is always in a micro-positive pressure gas seal state, and rolling oil can be prevented from entering the bearing seat 2 and the.
Referring to fig. 1, a gas seal is added between the water seal and the oil seal, the gas pressure of the gas seal is adjustable, the gas seal pressure is adjusted in a linkage manner at any time according to the rotating speed of the rolling mill roller 1, the gap is kept in a micro positive pressure state all the time, the oil/water infiltration at two sides can be sealed, and the gas consumption is low. The fixed end cover 5 is arranged above the spacer ring 6, the rubber sealing rings 3 are arranged on two sides of the spacer ring 6, a concave part is arranged in the middle of the spacer ring 6, compressed gas 7 can be placed in the concave part to form a gas seal, and the lubricating grease 8 is arranged between the rubber sealing rings 3 and the bearing seat 2.
In conclusion, the leakage-proof device for the thin oil lubrication bearing seat of the invention keeps the gap between the roller and the bearing seat at positive pressure all the time when the roller rotates by introducing compressed air to the gap between the roller and the bearing seat, thereby preventing rolling oil from entering the bearing seat and preventing lubricating oil from leaking out of the bearing seat, and having the advantages of low consumption of compressed air, low improvement cost investment and wide application range.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and those skilled in the art can make many variations and modifications of the present invention without departing from the scope of the present invention as defined in the appended claims.
