[0002] Thin-walled angular contact ball bearings are precision mechanical components that convert the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction losses. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. The inner ring is used to match the shaft and rotate with the shaft. The outer ring is used to match the bearing seat and play a supporting role. The rolling element is evenly distributed between the inner and outer rings with the help of the cage. Its shape, size and number directly affect the performance and life of the rolling bearing. The cage can evenly distribute the rolling element and guide the rolling element to rotate to play a lubricating role.

[0003] When the existing thin-walled angular contact ball bearings are working, in order to prevent the raceways and balls of the main shaft bearings from rubbing against each other too much and generating high temperature and thus being damaged and failing, it is necessary to spray lubricating oil on the main shaft bearings. However, the staff needs to hold the lubricant and spray the inside of the bearings, which is inconvenient. Summary of the invention

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A thin-walled angular contact ball bearing that can be quickly lubricated, such as Figure 1-6As shown, it includes a bearing assembly 100, which includes an outer ring 110. A lubrication assembly 200 is fixedly connected to the interior of the outer ring 110, and a clamping assembly 300 is provided at the upper and lower ends of the inner wall of the outer ring 110. The lubrication assembly 200 includes six groups of piston cylinders 210 fixedly connected to the interior of the outer ring 110, and pistons 220 are slidably connected to the inner walls of the six groups of piston cylinders 210. A piston rod 230 is welded to one side of the piston 220, and a spring 240 is sleeved on the surface of the piston rod 230. A spray pipe 250 is connected to the side of the piston cylinder 210 away from the surface of the outer ring 110, and an oil extraction pipe 260 is fixedly connected to the top of the piston cylinder 210. A connecting groove 231 opened in the interior of the outer ring 110 is provided on the side of the piston rod 230 away from the piston 220, and a ball 270 is slidably connected to the end of the connecting groove 231 away from the piston rod 230.

[0027] The inner ring 120 rotates to drive the connecting frame 130 to rotate, and the connecting frame 130 drives the ball 140 to slide against the outer ring 110. When the ball 140 rotates, it will contact the sphere 270, so that the sphere 270 is forced to move toward the inside of the connecting groove 231. When the air inside the connecting groove 231 is squeezed by the sphere 270, the piston rod 230 moves, and the piston rod 230 drives the piston 220 to stretch the spring 240 and squeeze the lubricating oil inside the piston cylinder 210, so that the lubricating oil is sprayed into the bearing through the spray pipe 250 to lubricate the ball 140, reduce the friction coefficient of the bearing, and extend the service life. At the same time, self-lubrication can be achieved through the rotation of the ball 140 without manual spraying. When the ball 140 releases the squeezing of the sphere 270, the sphere 270 drives the piston 220 to reset under the reaction force of the spring 240, and the lubricating oil can be extracted into the oil storage tank 112 through the oil extraction pipe 260 under the action of the one-way plate.

[0028] See also Figure 1 and Figure 6 The clamping assembly 300 includes a sealing cover 310 that is attached to the upper and lower ends of the inner part of the outer ring 110, and a clamping block 320 is slidably connected to the inner wall of the sealing cover 310. An elastic pad 330 is fixedly connected to the inner wall of the sealing cover 310 on one side of the clamping block 320, and a clamping groove 121 that matches the clamping block 320 is provided inside the inner ring 120.

[0029] By pulling the vertical plates 340 on both sides, the card block 320 is driven to move to both sides and squeeze the elastic pad 330, so that the card block 320 is disengaged from the card slot 121, and the fixation of the sealing cover 310 is released, so that the internal components of the utility model can be replaced easily. At the same time, the sealing cover 310 can prevent external debris from entering the interior of the utility model and affecting the operation of the utility model.

[0030] See also Figure 2 and Figure 6An inner ring 120 is provided on the inner wall of the outer ring 110, and a plurality of groups of balls 140 are arranged in a circular shaft array between the outer ring 110 and the inner ring 120. The balls 140 are slidably connected to the outer ring 110, and a connecting frame 130 rotatably connected to the outer wall of the inner ring 120 is provided on the surface of the balls 140. A vertical plate 340 is fixedly connected to the top of the block 320, and sliding grooves 311 are provided on both sides of the top of the sealing cover 310.

[0031] By providing the ball bearings 140 , the friction coefficient between the ball bearings 140 and the inner wall of the outer ring 110 can be reduced, and the vertical plate 340 can be pulled out of the sealing cover 310 through the sliding groove 311 .

[0032] See also Figure 3 , Figure 4 and Figure 5 An oil filling hole 111 is provided at the top of the outer ring 110, a sealing plug 280 is provided inside the oil filling hole 111, an oil storage tank 112 is provided inside the outer ring 110, and a one-way sheet is provided at the connection position between the oil extraction pipe 260, the spray pipe 250 and the piston cylinder 210, and the top of the oil extraction pipe 260 is connected to the oil storage tank 112.

[0033] The sealing plug 280 is pulled out, and lubricating oil is injected through the oil filling hole 111 to facilitate the subsequent lubrication of the utility model.

[0034] When in use, the inner ring 120 rotates to drive the connecting frame 130 to rotate, and the connecting frame 130 drives the ball 140 to slide against the outer ring 110. When the ball 140 rotates, it will contact the sphere 270, so that the sphere 270 is forced to move toward the inside of the connecting groove 231. When the air inside the connecting groove 231 is squeezed by the sphere 270, the piston rod 230 moves, and the piston rod 230 drives the piston 220 to stretch the spring 240 and squeeze the lubricating oil inside the piston cylinder 210, so that the lubricating oil is sprayed into the bearing through the spray pipe 250 to lubricate the ball 140, thereby reducing the friction coefficient of the bearing and extending its service life. At the same time, self-lubrication can be achieved through the rotation of the ball 140 without manual spraying. When the ball 270 is squeezed, the ball 270 drives the piston 220 to reset under the reaction force of the spring 240, and the lubricating oil can be extracted into the oil storage tank 112 through the oil extraction pipe 260 under the action of the one-way plate; when the internal components of the bearing need to be replaced, the vertical plates 340 on both sides are pulled to drive the block 320 to move to both sides and squeeze the elastic pad 330, so that the block 320 is disengaged from the slot 121, and the sealing cover 310 is released, so that the internal components of the utility model can be replaced. At the same time, the sealing cover 310 can prevent external debris from entering the interior of the utility model and affecting the operation of the utility model. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
