Description

Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to an oil injection device for bearing production. Background Art

[0002] Bearings are important components in mechanical equipment. They are mainly used to support mechanical rotation, reduce the friction coefficient during rotation, and ensure rotation accuracy. Bearings can be divided into two categories: rolling bearings and sliding bearings. Bearings need to be oiled during assembly to play a lubricating role.

[0003] When oiling a bearing, the amount of oil should not be too much or too little. Too much oil will cause too much grease to be added inside the bearing, affecting the running stability of the bearing. Too little oil will cause the protective film to fail to form inside the bearing, affecting the life of the bearing. However, the oiling device for bearing production in the prior art can only oil one surface of the bearing when oiling the bearing, filling the bearing with a circle of grease. However, the grease is not evenly distributed in the bearing steel balls and rings. The uneven distribution of lubricating oil will lead to insufficient lubrication in certain areas, thereby increasing the friction in these areas. In the long run, the wear of the bearing will be aggravated and its service life will be shortened. Therefore, a bearing production oiling device is proposed to solve the above problems.
