Bearing structure with convenient lubricating oil adding

Abstract

The invention relates to the technical field of bearings, in particular to a bearing structure with convenient lubricating oil adding. The bearing structure comprises a bearing inner ring, a bearing outer ring and a roller retainer, the roller retainer comprises an upper annular seat and a lower annular seat, a plurality of upright posts are fixedly arranged on the upper end face of the lower annular seat, and the upright posts are rotatably sleeved with cylindrical rollers; the upper annular seat is fixed to the tops of the upright posts through screws, a set of vertical rods are arranged between every two adjacent cylindrical rollers, the vertical rods are sleeved with lubricating cotton rollers, an annular containing cavity containing lubricating oil is formed in the upper annular seat, an oil injection hole is formed in the upper right end of the annular containing cavity, and a rubber plug is inserted into the oil injection hole; and a flow gathering cavity and a main flow cavity are sequentially formed in each vertical rod from top to bottom, C-shaped flow dividing channels communicating with the main flow cavity are formed in the two sides of the bottom of the flow gathering cavity, and branch flow grooves are evenly distributed in the periphery of the main flow cavity in a crotch-shaped structure. The bearing structure has the effect of supplementing oil in time, the service life of a bearing is greatly prolonged, and the use cost of mechanical equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing structure which is convenient for adding lubricating oil. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support mechanical rotation, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into rolling bearings and bearings. There are two categories of sliding bearings, among which rolling bearings have been standardized and serialized; [0003] The application number is CN202011002092.9 Chinese invention patent A sealed separable cylindrical roller bearing, including an outer ring, an inner ring and a roller ring, the outer side of the outer ring is provided with a first wear-resistant ring, A first sealing ring is fixed on the side and back side, a second sealing ring is f...

AI Technical Summary

Problems solved by technology

However, there are still some problems in the use of the roller bearing;

[0004] Due to the long-term use of the bearing, the lubricating oil inside the bearing is less and less, which makes the wear between the cylindrical roller and the inner ring more and more severe. In order to prolong the service life of the bearing, it is necessary to add lubricating oil to the bearing raceway, but , the above-mentioned bearings are very inconvenient to fill with lubricating oil, and do not have the performance of timely replenishment, which greatly reduces the service life of the bearings and increases the cost of mechanical equipment
