[0025] The lateral positioning plate 302 is provided to facilitate positioning of the bearing so that the bearing coincides with the top of the grease injection hole 304 and the grease discharge hole 303. The grease injection hole 304 is provided and a grease injection joint 305 is provided outside the grease injection hole 304 to facilitate injection of lubricating oil into the bearing gap. The grease discharge hole 303 is provided to facilitate the use of pressure to squeeze out excess lubricating oil from the grease discharge hole 303 after the bearing is greased. The grease discharge state is determined by observing the grease discharge hole 303.
[0026] See also Figure 3A ball groove 201 is provided on the top of the base 2, and a ball head 202 is rotatably connected inside the ball groove 201. An upper pressure plate 203 is fixedly connected to the bottom of the base 2.

[0028] Working principle: when a bearing grease filling device is used, in the initial state, first, the base 2 is set inside the fixed frame 1, and a ball head 202 is rotatably connected in the ball groove 201 opened on the top of the base 2, and the force screw 102 connected to the top of the ball head 202 is threadedly connected to the adjusting nut 101. At the same time, an upper pressure plate 203 is also set at the bottom of the base 2 to clamp and fix the bearing. A grease discharge hole 303 and a grease injection hole 304 are opened on the grease injection seat 301 set below the upper pressure plate 203. A grease injection joint 305 is connected to the front end of the grease injection hole 304, and a lateral positioning plate 302 is set on the front side of the grease injection seat 301 to facilitate the positioning and grease injection of the bearing;
[0029] When the bearing needs to be greased, first place the bearing on the grease injection seat 301 and fit it against the inner side of the lateral positioning plate 302 for positioning, so that the bearing is located above the oil outlet of the grease injection hole 304, then hold the rotating rod 103 to drive the force screw 102 to rotate clockwise, so that the force screw 102 begins to move downward under the control of the adjusting nut 101, and pushes the base 2 and the upper pressure plate 203 to move downward and contact the top surface of the bearing until the upper pressure plate 203 and the grease injection seat 301 clamp and fix the bearing, so that the outer ring and inner ring of the bearing are pressed tightly with the base 2 and the upper pressure plate 203 without any gap, and the balls and cages in the bearing are slightly lower than the inner and outer rings of the bearing. At this time, connect the external grease injection pipe The grease injection operation is performed on the grease injection joint 305. Since the grease injection hole 304 is opened at the internal position of the inner and outer rings of the bearing, the grease passes through the grease injection joint 305 and the grease injection hole 304 directly into the ball and retaining frame between the inner and outer rings to achieve the grease injection purpose. After the lubricating oil enters the interior of the bearing through the grease injection hole 304 from the grease injection joint 305, the lubricating oil entering the interior of the bearing fills the internal gap of the bearing from front to back until it is completely filled. After the lubricating oil in the bearing is filled, the excess lubricating oil will enter the interior from the top of the grease discharge hole 303 and be squeezed out. After the lubricating oil is discharged from the grease discharge hole 303, it can be determined that the lubricating oil filling in the bearing is completed. The device is convenient for greasing the bearing.
