Description

Technical Field

[0001] The utility model belongs to the technical field of bearing grease injectors, and particularly relates to a bearing grease injector that can ensure uniform grease injection. Background Art

[0002] The designs of many grease injectors fail to effectively achieve uniform release of lubricating grease, resulting in uneven distribution of lubricating grease inside the bearing. Some areas may be over-lubricated and cause oil film rupture, while other areas may experience accelerated wear due to insufficient lubrication. The main causes of these drawbacks are related to the structure of the grease injector and the overall design of the lubrication system. The grease injection holes of many products are small or have unreasonable shapes, restricting the flow of lubricating grease. In addition, during use, since many grease injectors are not easy to disassemble and clean, it is easy to cause the problem of poor grease injection in some grease injection holes.

[0003] Conventional countermeasures include adopting multi-point grease injection design, improving the structure of the grease injector, and selecting suitable lubricating grease, etc., aiming to improve the uniform spreading ability of lubricating grease. However, the disadvantages of these methods are that although multi-point grease injection can improve the distribution of lubricating grease, in practical applications, the complexity of maintenance and installation increases. Therefore, we hope to design a bearing grease injector with a new structure to solve this problem. Summary of the Utility Model

[0011] As a preferred embodiment, a diversity cavity is formed by downward depression at the upper end of the diversity box. The diameter of the diversity cavity is the same as that of the accommodation cavity, and the upper end of the diversity cavity is communicated with the lower end of the accommodation cavity. The setting of the diversity cavity is used to store the lubricating oil flowing into the accommodation cavity, and evenly transport the lubricating oil into a plurality of branch pipes through a plurality of uniformly distributed guide holes on its lower side, which helps to improve the grease injection uniformity of the whole structure.
