[0002] Bearings are an important and indispensable part of mechanical operation. Grease is added to bearings during use to reduce the friction coefficient and extend their service life.
[0003] According to the existing technology, a large amount of grease is added to the bearing when adding grease, and it cannot penetrate into the bearing during adding, so the grease is unevenly distributed inside the bearing, which will cause some parts of the bearing that are not covered by grease or are less covered by grease, resulting in insufficient lubrication, and excessive lubrication in other parts. In this way, some parts of the bearing will wear out when the bearing is working, and the temperature of the grease will increase when friction occurs in certain positions. The grease will accelerate oxidation and degradation, thereby causing the bearing temperature to rise, and the parts inside the bearing will experience thermal expansion and cracking, thereby reducing the service life of the bearing.

[0022] One end of the rotating rod 3 is rotatably connected to the top center position of the conveying tube 1 in a through-shape, a connecting tube 20 is fixedly connected to the bottom of the conveying tube 1, a handle 8 is fixedly connected to the side wall of the conveying tube 1 in a connected shape, a conveying cylinder 19 is rotatably connected inside the handle 8, a control block 16 is fixedly connected to the top of the handle 8, one end of the handle 8 is fixedly connected to a storage box 17 in a connected shape, a feeding port 18 is provided on the top of the storage box 17, the second bevel gear 5 is hollow, and one side of the second bevel gear 5 is connected to the conveying cylinder 19.
[0023] In the first embodiment, when the motor 2 rotates, the first bevel gear 4 on the rotating rod 3 is driven to rotate. When the first bevel gear 4 rotates, it can drive the conveying cylinder 19 in the second bevel gear 5 to rotate. The rotating rod 6 in the conveying cylinder 19 drives the conveying bar 7 to draw the grease in the storage box 17 into the conveying tube 1. The transportation by mechanical rotation can ensure that the grease is transported at a stable speed and reduce the mixing of gas during transportation. In this way, when filling, the gas will not suddenly spray out to disperse the injected grease, thereby ensuring that the grease can be evenly covered on the inside of the bearing when added, thereby ensuring that the grease is evenly covered in the bearing, which can ensure that the bearing can work normally without excessive wear and tear, thereby ensuring the service life of the bearing.
[0024] A reciprocating screw 10 is fixedly connected to the bottom of the conveying shaft 9, one end of the reciprocating screw 10 is threadedly connected to a diverter block 11 in a through-shape, a moving block 12 is fixedly connected to the bottom of the diverter block 11, a feed block 13 is fixedly connected to the bottom of the moving block 12, a push plate 14 is symmetrically fixedly connected to the outer wall of the reciprocating screw 10, one end of the feed block 13 is slidably connected to a filling pipe 15 in a through-shape, one end of the filling pipe 15 is fixedly connected to a pressure plate 21 in a connecting shape, the filling pipe 15 is annularly arranged on the side wall of the pressure plate 21, the feed block 13 is annularly fixedly connected to the bottom of the moving block 12, and the number of feed blocks 13 corresponds to the number of filling pipes 15.
[0025] In the second embodiment, the grease can be driven to move downward when the conveying shaft 9 rotates, thereby accelerating the speed of the grease movement, which is beneficial to improving the efficiency of filling, and the feed amount during each filling can be controlled when the diverter block 11 is used for diversion. This can avoid excessive grease filling during filling, resulting in excessive lubrication of the bearing. At the same time, it can also reduce the number of times of cleaning the excess grease, reduce the waste of grease, and save costs.
[0026] The working principle and use process of the utility model are as follows: when the motor 2 rotates, it can drive the first bevel gear 4 and the conveying shaft 9 on the rotating rod 3 to rotate. The first bevel gear 4 drives the rotating rod 6 in the conveying cylinder 19 to rotate through the second bevel gear 5. The rotating rod 6 drives the conveying bar 7 to draw the grease in the storage box 17 into the conveying tube 1. At the same time, the conveying shaft 9 pushes the grease in the conveying tube 1 into the connecting tube 20. At the same time, the reciprocating screw 10 at the bottom of the conveying shaft 9 can drive the diverter block 11 to reciprocate. At the same time, the moving block 12 at the bottom of the diverter block 11 can drive the feed block 13 to enter the filling pipe 15. The pushing plate 14 at the bottom of the reciprocating screw 10 can push the grease to the top of the filling pipe 15 and wait for the feed block 13 to be pushed into the filling pipe 15.
