High-speed rolling bearing lubrication device

Abstract

The invention belongs to the technical field of fluid lubrication, and particularly relate to a bearing lubrication device. The invention adopts a technical scheme as following: the high-speed rolling bearing lubrication device comprises a bearing external ring (1), a rolling element (2), as well as a bearing internal ring (3), an oil inlet sleeve (5) and an oil distribution sleeve (6). According to the high-speed rolling bearing lubrication device, a special lubrication oil channel is from in one side of a bearing, so as to enable lubrication oil entering a lubrication system not only to achieve effects of oil spraying and lubricating, but also to retain a certain amount of lubrication oil in the bearing internal ring, that too little lubrication oil is in the bearing internal ring under high-speed centrifugal force is avoided, and excessive temperature rising is prevented; in addition, an oil storage cavity in one side of the bearing internal ring can play a role of bearing cooling.

Description

technical field [0001] The invention belongs to the technical field of fluid lubrication, and in particular relates to a bearing lubrication device. Background technique [0002] The rolling bearings in the high-speed transmission of vehicles will generate a lot of heat when they run at high speed, which will cause the temperature rise of the bearings to be too high. Reasonable lubrication methods and devices can effectively take away the heat generated by the bearings and reduce the temperature rise of the bearings. When the rolling bearing is running at high speed, due to the effect of centrifugal force, the lubricating oil sprayed into the bearing will be thrown to the raceway of the outer ring of the bearing under the action of centrifugal force, so that the amount of lubricating oil in the inner ring of the bearing is reduced or even insufficient, and the inner ring of the bearing In high-speed rotation, the temperature of the inner ring of the bearing is much higher th...

AI Technical Summary

Problems solved by technology

When the rolling bearing is running at high speed, due to the effect of centrifugal force, the lubricating oil sprayed into the bearing will be thrown to the raceway of the outer ring of the bearing under the action of centrifugal force, so that the amount of lubricating oil in the inner ring of the bearing is reduced or even insufficient, and the inner ring of the bearing In high-speed rotation, the temperature of the inner ring of the bearing is much higher than that of the outer ring. If the temperature rise of the inner ring of the bearing is too high, it is easy to cause wear and scorching of the inner ring, which will damage the performance of the bearing and affect the performance of the entire transmission system.
