[0027] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0029] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0030] like Figures 1 to 6 The main structure of a bearing grease filling device shown in the figure is a bearing fixing base plate 1 and a bearing grease application arc frame 13. The arc angle of the arc frame 13 matches the arc shape of the bearing to be greased, so that the bearing can be easily filled with grease.

[0031] A circular groove 2 is formed on the top surface of the bottom plate 1, and two arc-shaped plates 3 are symmetrically arranged inside the circular groove 2. A connecting rod 5 is fixedly connected to the outer wall of the arc-shaped plate 3. The connecting rod 5 is slidably sleeved on the rod wall of the connecting rod 5. The limiting cylinder 4 is fixedly connected to the inner wall of the circular groove 2. A spring 18 is fixedly connected to the inside of the limiting cylinder 4. The spring 18 is a damping device.

[0032] The end of the spring 18 is fixedly connected to the connecting rod 5, and the spring 18 pushes the connecting rod 5 to which the end is fixedly connected to push the arc plate 3 tightly to the side wall of the bearing, thereby limiting and fixing the bearing;

[0033] Two vertical plates 6 are symmetrically fixedly connected to the top surface of the bottom plate 1, a cross bar 7 is fixedly connected between the two vertical plates 6, a motor 8 is fixedly connected to the top surface of the cross bar 7, and the rotating shaft of the motor 8 rotates and extends to the bottom of the cross bar 7 and is fixedly connected to a rotating tube 9, the outer wall of the rotating tube 9 is rotatably sleeved with a sleeve 10, and an oil inlet hole is opened on the side wall of the rotating tube 9, and the oil inlet hole is located at the sleeve connection of the sleeve 10. Thanks to the oil inlet hole being located at the sleeve connection of the sleeve 10, it is possible to pass grease into the interior of the rotating tube 9 through the sleeve 10 without affecting the normal rotation of the rotating tube 9;

[0034] An L-shaped tube 12 is rotatably sleeved in the lower opening of the rotating tube 9, and a filling tube 14 is slidably sleeved in the L-shaped tube 12. The top surface of the arc frame 13 is connected to the filling tube 14. Thanks to the sliding sleeve of the filling tube 14 inside the L-shaped tube 12, the position of the arc frame 13 can be adjusted. The position of the arc frame 13 can be adjusted according to the diameter of the bearing, so that grease can be applied to bearings of different diameters.

[0035] A sealing ring is slidably connected between the inner wall of the rotating tube 9 and the outer wall of the L-shaped tube 12, and an O-ring is slidably connected between the inner wall of the L-shaped tube 12 and the outer wall of the filling tube 14. Thanks to the setting of the sealing ring and the O-ring, an effective seal can be formed between the rotating tube 9 and the L-shaped tube 12, and a seal can be formed between the L-shaped tube 12 and the filling tube 14.

[0036] An annular plate 15 is fixedly sleeved on the outer walls of the rotating tube 9 and the L-shaped tube 12, and a push spring 16 is fixedly connected between the two annular plates 15. The push spring 16 installed between the rotating tube 9 and the L-shaped tube 12 pushes the arc frame 13 to be clamped to the top surface of the bearing, so that the arc frame 13 fits tightly with the top surface of the bearing, thereby improving the filling effect of the grease.

[0037] A damping rod 17 is fixedly installed between the annular plate 15 between the rotating tube 9 and the outer wall of the L-shaped tube 12, and the damping rod 17 is slidably sleeved inside the push spring 16. Thanks to the setting of the damping rod 17, it can effectively prevent the device from vibrating during operation, causing the push spring 16 to shake and affect the filling effect of the grease.

[0038] Two limit grooves are symmetrically opened on the inner wall of the limit cylinder 4, and two limit blocks 19 are symmetrically fixedly connected to the side wall of the connecting rod 5. The two limit blocks 19 fixedly connected to the side wall of the connecting rod 5 are respectively slidably connected to the inside of the two limit grooves opened on the inner wall of the limit cylinder 4. Thanks to the setting of the limit blocks 19, the sliding direction of the connecting rod 5 can be effectively limited, and the stability of the connecting rod 5 when sliding can be further improved.

[0039] How it works

[0040] When using the bearing grease filling device, first place the bearing to be greased between the two arc-shaped plates 3, then push the connecting rod 5 fixedly connected at its end by the spring 18 to push the arc-shaped plate 3 tightly to the side wall of the bearing, so as to limit and fix the bearing, and then pass the grease into the interior of the sleeve 10 through the connecting pipe connected on the side wall of the sleeve 10. At this time, since an oil inlet hole is opened on the side wall of the rotating tube 9, and the oil inlet hole is located at the socket of the sleeve 10, the grease is passed into the interior of the rotating tube 9 through the oil inlet hole, and then the grease is passed into the interior of the L-shaped tube 12 through the rotating tube 9. The grease is then passed into the filling tube 14 and the inside of the arc frame 13 through the L-shaped tube 12. At this time, the arc frame 13 is pushed to the top surface of the bearing by the push spring 16 installed between the rotating tube 9 and the L-shaped tube 12. Then, the motor 8 is started to drive the rotating tube 9, the L-shaped tube 12 and the arc frame 13 to rotate while applying the grease to the inside of the bearing. At the same time, thanks to the sliding sleeve of the filling tube 14 on the inside of the L-shaped tube 12, the position of the arc frame 13 can be adjusted, and the position of the arc frame 13 can be adjusted according to the diameter of the bearing, so as to realize the application of grease to bearings of different diameters.
