Compared with the prior art, the present utility model omits the step of manually applying grease, thereby improving the greasing efficiency.

[0044] The specific structure of the bearing greasing device is described as follows: It includes a machine body 1, and a cavity 11 is formed inside the machine body 1; a greasing mechanism 2 is arranged at the top of the machine body 1; a main greasing pipe 3 is arranged on one side of the machine body 1, the feed end of the main greasing pipe 3 is located outside the machine body 1, and the discharge end of the main greasing pipe 3 is located inside the cavity 11; a diverter 41 is arranged inside the cavity 11, and the diverter 41 is connected to the discharge end of the main greasing pipe 3; greasing branch pipes 5 are also arranged inside the cavity 11, the inlet of the greasing branch pipe 5 is connected to the diverter 41, and the outlet of the greasing branch pipe 5 is connected to the greasing mechanism 2. Compared with the prior art, the present utility model omits the step of manually applying grease, thereby improving the greasing efficiency.

[0045] In a specific application scenario, as shown in the appendix Figure 1 As shown, a workbench is usually provided at the top end of the machine body 1. The workbench is disc-shaped, and a through hole communicating with the cavity 11 is opened at the top of the workbench. Such a design facilitates the main greasing pipe 3 to transport the grease to the through hole of the workbench through the diverter 41 and the greasing branch pipes 5.

If the specific data reaches the preset value, the branch valve and the main valve are closed, and the grease injection main pipe 3 and the grease injection branch pipe 5 will no longer deliver grease to the workbench, and then reset the data currently detected by the flow sensor to facilitate the next detection; in addition, the grease injection main pipe 3 and the grease injection branch pipe 5 can be pressure-bearing hoses, and these pressure-bearing hoses can withstand the liquid pressure brought by the grease during the conveying process, thereby extending the service life of the present utility model to a certain extent; usually, the pipe orifice size of the grease injection main pipe 3 is larger than the pipe orifice size of the grease injection branch pipe 5. When in use, first place the grease injection main pipe 3 into the grease injection raw material barrel; then, adjust the power of the peristaltic pump to the appropriate range and start the peristaltic pump, and the grease in the grease injection raw material barrel starts to flow into the bearing grease injection device from the grease injection main pipe 3; the grease flows through the grease injection main pipe 3, the diverter 41, and the grease injection branch pipe 5 to the workbench, and the diverter 41 can reduce the liquid pressure generated when the grease in the grease injection main pipe 3 flows to the grease injection branch pipe 5; during this process, the real-time information of the grease flowing from the grease injection branch pipe 5 to the workbench is detected by the flow sensor, and the flow sensor transmits this flow information to the control panel 6 in the form of data, and this data can be displayed on the screen of the control panel 6 for the user to view; after a period of time, when the user finds that the data reaches the preset value by himself, press the button on the control panel 6 to immediately close the branch valve and the main valve, the grease in the grease injection main pipe 3 and the grease injection branch pipe 5 stagnates, turn off the peristaltic pump, and at the same time reset the data detected by the flow sensor. Such a design realizes the purpose of the grease in the grease injection raw material barrel flowing to the workbench.

The grease injection seat 22 includes a convex portion 221 and a concave portion 222, as shown in the appendix Figure 3 As shown; a grease injection hole 2211 is formed in the convex portion 221, and the concave portion 222 is arranged adjacent to the convex portion 221; wherein, the grease injection seat 22 is disc-shaped, and a plurality of convex portions 221 and a plurality of concave portions 222 are arranged in a circumferential array at the top end of the grease injection seat 22; the convex portion 221 is in a convex arc shape, and the concave portion 222 is in a concave arc shape, and the concave portion 222 is adapted to the balls in the bearing. When only the bearing with balls is placed on the grease injection seat 22, the convex portion 221 can separate the adjacent balls, and the balls just fall on the corresponding concave portions 222; usually, a grease injection channel is formed at the top end of the base 21, and the inner wall of the grease injection channel is connected to the discharge port of the grease injection branch pipe 5. The grease in the grease injection branch pipe 5 can directly flow into the grease injection channel; in addition, a plurality of grease injection sub-channels are formed inside the grease injection seat 22, and the number of the grease injection sub-channels is the same as the number of the grease injection holes; the grease injection sub-channels on the grease injection seat 22 are all communicated with the grease injection channel, so that the grease in the grease injection branch pipe 5 can pass through the grease injection channel, the grease injection sub-channels, and finally overflow from the grease injection holes 2211; of course, the user can set a plurality of grease injection mechanisms 2 on the workbench according to his own needs, set the corresponding number of grease injection branch pipes 5 on the diverter 41, open the corresponding number of through holes on the workbench, and also set the corresponding number of sub-valves and flow sensors.

During use, place the bearing to be greased and only containing ball bearings on the grease injection seat 22; at this time, the convex part 221 on the grease injection seat 22 can adjust the spacing between adjacent ball bearings on the bearing to a preset condition, and the ball bearings fall into the concave part 222 on the grease injection seat 22; then, turn on the peristaltic pump, and the grease in the grease injection raw material barrel flows through the main grease injection pipe 3, the flow divider 41, the branch grease injection pipes 5, and the workbench into the grease injection channel in the base 21; then, the grease dispersedly flows from the grease injection channel into the branch grease injection channels in the grease injection seat 22, and the grease in the branch grease injection channels overflows from the corresponding grease injection holes 2211, and the grease adheres to the ball bearings of the bearing; after a period of time, the grease on the bearing reaches the preset value, close the branch valve on the branch grease injection pipe 5 and the main valve on the main grease injection pipe 3 through the operation control panel 6, turn off the peristaltic pump, and at the same time reset the data currently detected by the flow sensor, thus realizing the grease injection operation of the bearing. In addition, considering that multiple grease injection mechanisms 2 are provided on the workbench and are distributed at different positions, it may cause different speeds of transporting grease. When the grease injection of the bearing on one grease injection seat 22 is completed, just close the corresponding branch valve; if the grease injection of all the bearings above the workbench is completed, the user can close the main valve on the main grease injection pipe 3 and the peristaltic pump, and at the same time reset the data currently detected by all the flow sensors, which is convenient for the next detection. Such a design can further improve the grease injection efficiency to a certain extent.
