Description

Technical Field

[0001] The utility model relates to the technical field of bearing accessories, in particular to a bearing retainer with a lubricating function. Background Art

[0002] A bearing retainer is a bearing component that partially wraps around all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually guides the rolling elements and retains them in the bearing. To ensure that the bearing balls are stably wrapped by the retainer, the retainer is provided with mounting holes. The balls are located in the mounting holes and rotate with the mounting holes. To reduce ball wear and rolling noise, the balls need to be lubricated after the retainer and balls are mated.

[0003] However, after the ball bearings are lubricated, the lubricating oil on their surface is easily and quickly scraped off when the balls roll, and the scraped off lubricating oil is not easy to be reused, resulting in poor lubricating time of the lubricating oil. Utility Model Content

[0004] The utility model addresses the deficiencies in the prior art and provides a bearing retainer with a lubricating function. The specific technical solution is as follows:

[0005] A bearing retainer with a lubrication function includes a retainer body, a plurality of ball placement holes are provided on the retainer body, an oil guide groove is provided between two adjacent ball placement holes, the ends of the oil guide groove are connected with the adjacent ball placement holes, a plurality of oil flow grooves and a plurality of mounting grooves are provided on the inner wall of the ball placement hole, the oil flow groove is recessed toward the interior of the retainer body, one end of the mounting groove is connected with the ball placement hole, and the other end of the mounting groove is connected with the oil guide groove, a sponge is provided inside the mounting groove, one end of the sponge extends to the side of the ball placement hole, and the other end of the sponge extends to the interior of the oil guide groove.

[0006] As an improvement to the above technical solution: a plurality of comb flow grooves are provided inside the sponge, and the two ends of the comb flow grooves respectively pass through the two ends of the sponge.

[0007] As an improvement of the above technical solution: a plurality of oil filling holes connected to the oil guide groove are provided on the top of the retainer body, plugging covers are provided on the oil filling holes, and the oil guide groove is arranged in an arc shape.

[0008] As an improvement of the above technical solution: a plurality of the ball placement holes are arranged in a circular array on the side wall of the retainer body, one end of the ball placement hole passes through the inner side of the retainer body, and the other end of the ball placement hole passes through the outer side of the retainer body.

[0009] Beneficial effects of the utility model:

[0010] During use, when lubricating the ball installed in the ball placement hole, the ball will contact the ball placement hole during rolling, and part of the lubricating oil in the oil guide groove will be introduced into the ball surface to lubricate the ball. Part of the lubricating oil on the ball surface will be thrown into the oil flow groove during rolling, and part of the lubricating oil will be stored. Part of the lubricating oil will be introduced into the sponge through the installation groove, so that multiple sponges can absorb the lubricating oil, so that the end of multiple sponges close to the ball placement hole can coat the ball with lubricating oil. When there is too much lubricating oil on the ball surface, the lubricating oil will be absorbed by the sponge, and the lubricating oil can be reused, and excessive lubrication can be avoided from overflowing from the ball placement hole. When there is too little lubricating oil on the ball surface, the lubricating oil in the oil guide groove can also be introduced into the ball surface through the sponge, thereby effectively improving the continuous use effect of lubrication and maintaining the performance of the ball.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] Example

[0018] Please refer to Figure 1-Figure 4, a bearing retainer with a lubricating function, including a retainer body 1, a plurality of ball placement holes 2 are provided on the retainer body 1, the ball placement holes 2 are used to facilitate the placement of the balls, the retainer body 1 can be composed of two upper and lower annular blocks embedded to form a complete annular block, the ball assembly can be completed by placing the balls between the two annular blocks before assembly, this is a prior art, and this application will not go into details, an oil guide groove 3 is provided between two adjacent ball placement holes 2, the end of the oil guide groove 3 is connected to the adjacent ball placement hole 2, and the ball placement A plurality of oil flow grooves 5 and a plurality of mounting grooves 6 are provided on the inner wall of the release hole 2. The oil flow groove 5 is recessed into the interior of the retainer body 1. One end of the mounting groove 6 is communicated with the ball placement hole 2, and the other end of the mounting groove 6 is communicated with the oil guide groove 3. A sponge 4 is provided inside the mounting groove 6. One end of the sponge extends to the side of the ball placement hole 2, and the other end of the sponge extends to the interior of the oil guide groove 3.
