Description

Technical Field

[0001] This utility model relates to the technical field of rolling bearings, and in particular to a rolling bearing with a self-lubricating structure. Background Technology

[0002] As a core component in mechanical transmission, the lubrication effect of rolling bearings directly affects the operating efficiency and lifespan of equipment.

[0003] Based on the technical effects of existing technologies and solutions, there are still areas that need to be optimized: the lubrication method of traditional rolling bearings (such as deep groove ball bearings, cylindrical roller bearings, etc.) mainly relies on manual periodic oiling. By opening oil injection holes in the outer or inner ring of the bearing, lubricating oil is injected into the friction surface using a grease gun or oil pump, which is difficult to adapt to the real-time lubrication needs under high-speed operation or heavy load conditions.

[0004] This application utilizes the centrifugal force generated by the bearing's rotation to achieve real-time lubricant replenishment. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems existing in the above-mentioned rolling bearings with self-lubricating structures, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a rolling bearing with a self-lubricating structure, which aims to achieve lubricant replenishment by utilizing the centrifugal force generated by the bearing itself during rotation.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including an outer rotating ring and an inner rotating ring, wherein a plurality of balls are arranged on the inner side of the outer rotating ring and the inner rotating ring;

[0012] As a preferred embodiment of the rolling bearing with a self-lubricating structure described in this utility model, a pressing plate is provided on the inner side of the oil storage tank, a pressing rod is provided on the right side of the pressing plate, the right side of the pressing rod extends to the outer side of the rotating ring, and a trapezoidal block is provided on the right side of the pressing rod.

[0013] As a preferred embodiment of the rolling bearing with a self-lubricating structure described in this utility model, a spring is provided on the side opposite to the trapezoidal block and the rotating ring, and the spring is sleeved on the surface of the extrusion rod.

[0014] As a preferred embodiment of the self-lubricating rolling bearing of the present invention, a reset groove is provided on the outer side of the rotating ring, and a reset post is provided on the surface of the reset groove.

[0017] The beneficial effects of this utility model are as follows: When the bearing rotates, the centrifugal force generated by the counterweight pushes the trapezoidal block to compress the spring, which in turn drives the extrusion rod to extrude the oil-absorbing pad and release lubricating oil to the ball bearing, thus achieving a self-lubricating function without manual intervention.

[0027] Example 1

[0028] Reference Figures 1-4 This is the first embodiment of the present invention, which provides an oil injection mechanism 200 to realize the storage and controllable release of lubricating oil and provide continuous lubrication for rolling bearings.

[0029] It includes an outer rotating ring 101 and an inner rotating ring 102, and a plurality of balls 103 are provided on the inner side of the outer rotating ring 101 and the inner rotating ring 102;

[0030] The oil injection mechanism 200 includes a rotating ring 201 disposed inside the outer rotating ring 101 and the inner rotating ring 102, and oil injection components 202 are disposed on the left and right sides of the rotating ring 201.

[0031] The oil injection assembly 202 includes an oil reservoir 202a opened inside the rotating ring 201, and an oil injection pipe 202b is provided at the top of the oil reservoir 202a. The right side of the oil injection pipe 202b extends to the outside of the rotating ring 201.

[0032] An oil-absorbing pad 203 is provided on the inner side of the oil storage tank 202a. The oil-absorbing pad 203 is used to absorb lubricating oil.

[0033] Specifically, if the outer rotating ring 101 is in a fixed state during use, the rotating ring 201 is fixedly connected to the inner side of the inner rotating ring 102; otherwise, it is fixedly connected to the inner side of the outer rotating ring 101.

[0034] Furthermore, when lubrication is required, lubricating oil is injected into the oil reservoir 202a inside the rotating ring 201 through the oil injection pipe 202b. The oil-absorbing pad 203 on the inner side of the oil reservoir 202a absorbs the lubricating oil and keeps it moist. When the bearing is running, the oil-absorbing pad 203 contacts the ball 103 and slowly releases the lubricating oil to the surface of the ball 103 under friction, forming an oil film to reduce friction. This design uses the capillary action of the oil-absorbing pad 203 to store lubricating oil, avoiding direct oil leakage. At the same time, it achieves on-demand oil supply through squeezing release, ensuring that the bearing continuously receives lubrication during operation and reducing wear.

[0035] It should be noted that the oil-absorbing pad 203 can be lubricated when it comes into contact with the ball 103; it can also be lubricated when the extrusion plate 204 is pressed inward; a one-way valve can be installed in the oil injection pipe 202b for use in conjunction with this.

[0036] Example 2

[0037] Reference Figures 1-4 This is the second embodiment of the present invention, which provides an automatic extrusion oil injection structure driven by centrifugal force to achieve adaptive quantitative release of lubricating oil without the need for an external power source.

[0038] An extrusion plate 204 is provided on the inner side of the oil storage tank 202a. An extrusion rod 205 is provided on the right side of the extrusion plate 204. The right side of the extrusion rod 205 extends to the outer side of the rotating ring 201. A trapezoidal block 206 is provided on the right side of the extrusion rod 205.

[0039] A spring 207 is provided on the opposite side of the trapezoidal block 206 and the rotating ring 201, and the spring 207 is sleeved on the surface of the compression rod 205;

[0040] A reset groove 208 is provided on the outer side of the rotating ring 201, and a reset post 209 is provided on the surface of the reset groove 208;

[0041] A counterweight 210 is fixedly connected to the right side of the reset column 209, and one side of the counterweight 210 is in contact with the trapezoidal surface of the trapezoidal block 206.

[0042] The surface of the reset groove 208 is provided with an elastic reset member 211, and the upper and lower sides of the reset member 211 are fixedly connected to the inner wall of the reset groove 208 and the top of the reset post 209, respectively.

[0043] Specifically, when the bearing rotates, the centrifugal force generated by its own rotation can be used to drive the counterweight 210 to move, thereby achieving automatic replenishment of lubricating oil through mechanical linkage and providing lubrication to the bearing.

[0044] Furthermore, when the bearing rotates, the counterweight 210 on the outside of the reset groove 208 rotates with the rotating ring 201, generating centrifugal force to push the reset column 209 to move outward. The counterweight 210 on the left side of the reset column 209 contacts the inclined surface of the trapezoidal block 206. When the reset column 209 moves outward, the counterweight 210 presses the inclined surface of the trapezoidal block 206, and the trapezoidal block 206 presses the extrusion rod 205, which drives the extrusion plate 204 to move inward to the oil storage tank 202a, extruding the oil suction pad 203 to release lubricating oil. The higher the rotation speed, the greater the centrifugal force of the counterweight 210, the greater the pressure of the extrusion plate 204 on the oil suction pad 203, and the more lubricating oil is released. When the rotation speed decreases, the spring 207 pushes the trapezoidal block 206 to reset, the extrusion plate 204 releases the oil suction pad 203, and stops the extrusion and oil supply.

[0045] In summary: Through the design of the rotating ring 201, the oil injection component 202 and the counterweight 210, the centrifugal force generated by the bearing rotation drives the extrusion plate 204 to achieve adaptive release of lubricating oil, and the oil supply can be dynamically adjusted according to the rotation speed without manual intervention.
