Description

Technical Field

[0001] This utility model belongs to the field of oiling machine equipment, specifically relating to an oiling machine for grease injection into bearings. Background Technology

[0002] During bearing assembly, lubricating grease needs to be applied between parts to reduce friction and lower the coefficient of friction. When applying the lubricating grease, it should be applied as evenly as possible. When applying grease to internal components, some areas require deeper application, making it difficult for operators to reach deep into the components manually. A common method is to apply a large amount of lubricating grease to the surface of the bearing's internal components before installing the parts. However, this method cannot ensure that the lubricating grease is evenly applied to the inner walls of the components. Furthermore, the large amount of lubricating grease is wasteful and can damage areas requiring higher application rates, impairing the bearing's performance. Utility Model Content

In actual use, in order to control the direction of the oil outlet 14, the front end of the oil outlet 14 is a 90° bend. When the lubricating grease flows out from the oil supply pipe 12, the lubricating grease is located at the front end of the oil brush 5. As the oil brush 5 rotates, the bristles of the oil brush 5 evenly coat the lubricating grease on the inner wall of the inner component. The lower end of the oil supply pipe 12 is provided with an oil inlet 13, which is connected to the lubricating grease pump. The outer wall of the oil inlet 13 is provided with threads that are compatible with the oil outlet of the lubricating grease pump.
