DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0028] Reference Figure 1-Figure 6 A ball lubrication structure of a hidden multi-ball high-speed bearing comprises a bearing body 1, the bearing body 1 comprises an outer ring 2 and an inner ring 3, a plurality of balls 4 are arranged inside the bearing body 1, a lubrication component is arranged inside the outer ring 2, and dustproof components are arranged on both sides of the bearing body 1;

[0029] The lubrication assembly includes a first oil-absorbing cotton 6, and a ball 10 is provided on one side of the first oil-absorbing cotton 6. The number of the balls 10 is set to multiple, and the multiple balls 10 are arranged corresponding to the multiple balls 4. The first oil-absorbing cotton 6 and the multiple balls 10 are used to continuously lubricate the multiple balls 4.

[0030] Reference Figure 1-Figure 3 The lubrication assembly also includes an oil storage chamber 5, which is opened inside the outer ring 2. The first oil-absorbing cotton 6 is located on the side close to the ball 4. A plurality of through holes 12 are opened inside the outer ring 2. Each ball 10 is located inside the corresponding through hole 12. An oil filling hole 7 is opened on one side of the outer ring 2. The oil filling hole 7 is connected to the oil storage chamber 5. A second oil-absorbing cotton 11 is provided on the outer wall of each ball 10. A plurality of grooves 8 are opened on one side of the first oil-absorbing cotton 6. Each groove 8 is matched with the corresponding second oil-absorbing cotton 11. Each second oil-absorbing cotton 11 is matched with the corresponding through hole 12. Each second oil-absorbing cotton 11 is in contact with the outer wall of the corresponding ball 4. A rotating rod 9 is rotatably connected to the inside of each through hole 12. Each rotating rod 9 is fixedly connected to the corresponding ball 10.

[0031] The lubrication component can lubricate the ball 4 when the bearing body 1 is working. The specific operation method is: first, lubricating oil is injected into the oil storage chamber 5 through the oil filling hole 7, and a part of the lubricating oil will be absorbed by the first oil-absorbing cotton 6. When the first oil-absorbing cotton 6 is in a filled state, the second oil-absorbing cotton 11 will absorb the lubricating oil inside the first oil-absorbing cotton 6. When the inner ring 3 of the bearing body 1 rotates, the ball 4 will rotate. Since the ball 4 is in contact with the corresponding second oil-absorbing cotton 11, the ball 10 will be driven to rotate due to friction when the ball 4 rotates. The rotation of the ball 10 can ensure The contact surface of the ball 4 is always filled with lubricating oil, which can ensure that the lubricating oil is transferred to the ball 4 more evenly. Through continuous and effective lubrication, the friction between the ball 4 and other components can be greatly reduced, the degree of wear can be reduced, and the service life of the ball 4 and the entire bearing body 1 can be extended. The heat generated by the friction of the ball 4 can be reduced, and the performance degradation or damage of the bearing body 1 due to overheating can be avoided. Lubrication can also reduce operating noise. Excessive lubrication through the second oil-absorbing cotton 11 plays a certain filtering role, preventing impurities from excessively diffusing with the oil, further ensuring the effective use of the lubricating oil and avoiding waste.

[0032] Reference Figure 3 A sealing plug 13 is inserted into the oil filling hole 7, and the sealing plug 13 is interference fit with the oil filling hole 7. A pull block 14 is provided on one side of the sealing plug 13, and the sealing plug 13 can ensure the sealing of the oil storage chamber 5.

[0033] Reference Figure 4-Figure 6The dustproof assembly includes a dustproof plate 15, the number of which is set to two, and the two dustproof plates 15 are respectively located on both sides of the bearing body 1. Two matching grooves 16 are provided on both sides of the bearing body 1, and a matching block 20 is provided inside each matching groove 16. A slot 21 is provided on one side of each matching block 20. Fixed blocks 17 are fixedly connected to both sides of each dustproof plate 15, and a telescopic block 19 is provided inside each fixed block 17. A telescopic rod 18 is fixedly connected between each telescopic block 19 and the corresponding fixed block 17, and each telescopic block 19 is matched with the corresponding matching block 20, and each telescopic block 19 is plugged into the corresponding slot 21, and each telescopic block 19 is matched with the corresponding slot 21.

[0034] The dustproof component can play a role in preventing dust from falling on multiple balls 4 when the bearing body 1 is working. The specific installation method is to place two dustproof plates 15 close to the bearing body 1. When the telescopic block 19 contacts the matching block 20, it will retract into the corresponding fixed block 17. The telescopic block 19 will be inserted into the corresponding slot 21, thereby completing the installation of the dustproof plate 15. The dustproof plate 15 can effectively prevent external dust, impurities, etc. from entering the bearing body 1 and contacting the balls 4, avoiding dust and other damages such as wear and scratches on the balls 4, thereby extending the service life of the balls 4 and the entire bearing body 1. The dustproof plate 15 can maintain a clean environment inside the bearing body 1, reduce the probability of failures caused by dust, and reduce the cost of repair and maintenance.

[0035] Working principle: first, lubricating oil is injected into the oil storage chamber 5 through the oil filling hole 7, and a part of the lubricating oil will be absorbed by the first oil-absorbing cotton 6. When the first oil-absorbing cotton 6 is in a filled state, the second oil-absorbing cotton 11 will absorb the lubricating oil inside the first oil-absorbing cotton 6. When the inner ring 3 of the bearing body 1 rotates, the ball 4 will rotate. Since the ball 4 is in contact with the corresponding second oil-absorbing cotton 11, the friction will drive the ball 10 to rotate when the ball 4 rotates. The rotation of the ball 10 can ensure that the contact surface with the ball 4 is always filled with lubricating oil, which can ensure that the lubricating oil is more evenly transferred to the ball 4.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
