[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support a rotating mechanical body. Among them, a flanged bearing, also known as a flanged or flanged edge bearing, is a special rolling bearing design in which one end of the outer ring or inner ring is curled or folded to form an edge or lip. In order to reduce the friction coefficient during its movement and ensure its rotational accuracy, according to the usage requirements of the product, the bearing must be filled with a certain amount of grease before leaving the factory to ensure that the grease can be evenly and accurately injected into the bearing, thereby improving the working efficiency of the bearing and extending its service life.
[0003] Currently, there are the following defects in the way of greasing bearings:
[0004] 1. Operators manually inject grease into the bearing using a grease injection tube, which increases the workload of the operators and results in low grease injection efficiency for the bearing. Moreover, it is difficult for operators to ensure uniform grease injection and quantitative control of the grease injection volume when manually injecting with a grease injection tube.
[0005] 2. The existing automatic grease filling mechanisms have complex structures and high installation and maintenance costs.
[0006] 3. For the special structure of the flanged bearing, it is difficult for the clamping mechanism of the existing grease filling mechanism to achieve precise adaptation, and the improved design requires a high cost.

The workbench is partitioned, which is convenient for workers to operate and improves the processing effect.
[0033] Below the workbench 1, there is an oil drum 2 and a metering pump 3. Above the workbench 1, there are a fixed greasing head 4 and an induction switch 6.
