Description

Technical Field

[0001] This utility model belongs to the technical field of bearing grease injection heads, and relates to a bearing grease injection head that can ensure uniform grease injection. Background Technology

[0002] Existing bearing grease injection technology has several drawbacks in preventing grease leakage. First, limitations in the design of the bearing sealing structure are the main cause of leakage. The bearing cannot be grease-filled evenly. For example, if the clearance between the sealing lip and the bearing journal is too large, or if the sealing material is aged or hardened, it cannot effectively block the grease, thus leading to grease leakage and uneven grease injection.

[0003] Conventional solutions include using higher-quality seals, improving bearing housing design, and precisely controlling the grease injection volume. However, these methods also have drawbacks. Improving bearing housing design may require replacing or modifying existing equipment, which is not only time-consuming and labor-intensive but may also affect the normal operation of the equipment. While precisely controlling the grease injection volume can reduce overflow, it is difficult to guarantee that the grease injection will achieve the ideal state every time in actual operation, and it also requires a high level of technical skill from the operators. Conventional solutions can alleviate the problem to some extent, but they are often accompanied by increased costs, increased operational complexity, and potential performance limitations. Therefore, there is an urgent need for a bearing grease injector that can guarantee uniform grease injection to solve the above problems. Utility Model Content
