The lubrication mode of the bearing mainly comprises oil lubrication or grease lubrication, the current lubrication bearing in the bearing industry accounts for more than 70%, and unconditionally designed oil lubrication systems such as household appliances, motors, textile machinery and the like are designed, most of the lubrication modes adopt grease lubrication, and grease is injected into a raceway of the bearing. When the bearing runs, friction force is reduced, vibration is reduced and service life of the bearing is prolonged due to the action of grease. Because grease is not flowable like oil, has viscosity and poor fluidity, the original grease adding method is to scrape the grease into the bearing by a special tool (such as a saw blade), and then people improve the grease adding method into grease adding by a grease gun, but the grease adding is not easy to control, and the error is larger: if the grease injection amount is too small, grease deficiency or dry friction is easily caused, and the service life is influenced; and excessive grease injection can cause bearing temperature rise, so that a large amount of grease leakage not only pollutes the environment, but also causes waste.

When the grease in the quantifying cavity 35 is filled, the pressure of the grease in the oil inlet passage 31 is increased, so that the stress of the turntable 33 is increased, the limiting damping point 331 of the turntable 33 is extruded to cross the positioning damping point 321 of the positioning disk 32, and finally the turntable 33 rotates, at the moment, the circulating groove 332 is not communicated with the butt joint oil way 34 and the oil inlet passage 31, the pressing plate 36 is pushed to press the grease in the quantifying cavity 35 in the rotating process of the turntable 33, the blocking plate 381 of the oil outlet passage 38 is pushed away, the grease flows out from the oil outlet passage 38 into the oil injection cylinder 40, and the quantified grease is injected into the bearing through the oil injection cylinder 40;
Further, the pressing plate 36 is pulled to reset in the rotating process of the turntable 33, the limiting damping point 331 on the turntable 33 is limited by the positioning damping point 321 of the positioning disk 32 again, and the circulating groove 332 is also communicated with the butt joint oil path 34 and the oil inlet path 31 again, so that the oil inlet path 31 enters the quantifying cavity 35 to accumulate, and the next oil injection barrel 40 is used for injecting grease into the bearing.
When placing the bearing on the mounting platform 10, through pressing the bearing for the elastic head 13 on the external diameter extrusion positioning head 12 of bearing makes elastic head 13 take place to shrink, when the bearing gets into in the mount pad 11, fixes the bearing through elastic head 13 elasticity extrusion, later when annotating the grease to the bearing when annotating oil drum 40, through rotating mount pad 11, makes the bearing take place horizontal rotation, makes grease evenly get into in the bearing.
