Bearing convenient for adding of lubricating oil

Abstract

The invention relates to the technical field of bearings, in particular to a bearing convenient for adding of lubricating oil. The bearing comprises an inner ring and an outer ring, a retainer is arranged between the inner ring and the outer ring, dust covers are arranged at the upper end and the lower end of the retainer, an oil adding opening is formed in the dust cover on the upper portion of the retainer, and a sealing column is arranged in the oil adding opening. By arranging the oil adding opening and the sealing column, lubricating oil can be added into the bearing by pressing the sealing column to separate the sealing column from the oil adding opening, the situation that the interior of a bearing is contaminated with dust when a dustproof cover is detached is avoided, and after the lubricating oil is added, a spring can push the sealing column to be clamped to the oil adding opening, so that the interior of the bearing is sealed, and dust invasion and lubricating oil leakage are avoided; lubricating oil can flow to all balls through oil distribution openings, so that the surfaces of the balls are coated with the lubricating oil, and the lubricating effect is improved; and the situation that a dust cover needs to be detached when lubricating oil is added into a traditional bearing is changed through the design, the dust covers are prevented from being detached, and the situation that dust affects rotation of the bearing is prevented.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing which is convenient for adding lubricating oil. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. In order to reduce the internal friction and wear of the bearing, prevent the bearing from burning, discharge frictional heat, cool down, prevent the bearing from overheating, prevent rust and corrosion, etc., it is necessary to lubricate the bearing regularly to prolong the service life of the bearing. The lubrication methods of bearings are divided into grease lubrication and oil lubrication, and the lubricity of oil lubrication is more effective than grease lubrication. [0003] When using lubricating oil to lubricate the bearing, it is necessary to add lubricating oil peri...

AI Technical Summary

Problems solved by technology

The existing bearing needs to disassemble the dust cover and sealing ring outside the bearing when adding lubricating oil. The disassembly process is cumbersome and affects the efficiency of adding lubricating oil

In addition, after the dust cover is removed, the lubricating oil in the bearing is easily contaminated with dust in the air, which increases the internal friction of the bearing, resulting in a lower service life of the bearing
