[0005] This self-lubricating gear realizes automatic lubrication through the centrifugal force when the gear rotates. However, in the actual use process, since the gear is always in a high-speed rotation state, all the oil outlets are always in an open state, and the lubricant may be continuously released, which is not conducive to the effective management and recycling of the lubricant, thereby reducing the lubrication efficiency and resource utilization rate. Summary of the Utility Model

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Please refer to Figures 1 to 5 , a gear with good lubrication effect, including a wheel body 1, on which a shaft hole 2 and a keyway 3 are provided. The designs of the shaft hole 2 and the keyway 3 enable the entire gear to be simply and quickly installed on the corresponding shaft body, facilitating corresponding operations.

[0028] Gear teeth 4 are fixedly installed on the wheel body 1 at equal intervals and evenly.

[0029] An extrusion mechanism and a distribution mechanism are provided inside the gear teeth 4;

[0030] An elastic oil storage tank 6 is provided inside the gear teeth 4. One end of the elastic oil storage tank 6 is fixedly connected to the gear teeth 4. Both the left and right sides of the elastic oil storage tank 6 are made of rigid materials (one is a movable end and the other is a fixed end), and the middle of the elastic oil storage tank 6 is made of flexible material with accordion-shaped creases. By moving the rigid material at the movable end, the elastic oil storage tank 6 can be extruded.

[0031] As a preference, by setting a slider and a chute, the movable end can only move in one direction, thus ensuring the extrusion effect. Since the inside of the elastic oil storage tank 6 is sealed, the lubricating oil can smoothly flow out through the corresponding holes for lubrication activities.

[0032] An output port 14 is fixedly installed on the elastic oil storage tank 6, and the extruded lubricating oil flows out smoothly. An oil injection mechanism is also provided on the elastic oil storage tank 6 for refueling the elastic oil storage tank 6 to ensure the continuity of lubrication.

[0033] The distribution mechanism includes a delivery pipe 11, which is fixedly connected to the output port 14. Capillary tubes 12 are evenly embedded and installed on the delivery pipe 11 at equal intervals.

[0034] At the corresponding position on the gear teeth 4, there are oil outlets 8 adapted to the capillary tubes 12.

[0035] The extruded lubricating oil flows out smoothly through the delivery pipe 11, and then flows out through multiple capillary tubes 12. The existence of the oil outlets 8 enables the lubricating oil flowing out of the capillary tubes 12 to directly flow onto the surface of the gear teeth 4, facilitating the lubrication of the meshing gears.

[0036] The vertical part of the delivery pipe 11 can prevent the lubricating oil from flowing out smoothly when not being extruded. Cooperating with the extrusion mechanism, it can ensure that the lubricating oil does not flow out when not started.

[0037] The extrusion mechanism includes an extrusion plate 9, which is connected to the gear teeth 4 through a resilient member 10. The extrusion plate 9 can slide inside the gear teeth 4, and a contact block 5 is fixedly installed on the extrusion plate 9, with the contact block 5 protruding from the gear teeth 4.

[0038] When the gears mesh with each other, the contact block 5 will be extruded. Then, the contact block 5 can smoothly drive the extrusion plate 9 to move. The movement of the extrusion plate 9 will cause the elastic oil storage tank 6 to move, thus realizing the extrusion of the elastic oil storage tank 6 and enabling it to discharge oil.

[0039] The resilient member 10 includes a fixed cylinder 17, which is fixedly installed on the side wall of the gear teeth 4. A moving rod 16 is fixedly installed inside the fixed cylinder 17. One end of the moving rod 16 facing the fixed cylinder 17 is fixedly installed with a spring 18, and the other end of the spring 18 is fixedly installed on the gear teeth 4.

[0040] When not meshing, under the action of the spring 18, the moving rod 16 is pulled back to the side facing the fixed cylinder 17, so that the extrusion plate 9 does not contact the elastic oil storage tank 6. The elastic oil storage tank 6 is reset under its own elastic force, facilitating the next extrusion activity.

[0041] Since the elastic oil storage tank 6 is a sealed structure, as the internal lubricating liquid flows out, the pressure gradually increases, and the outflow of the lubricating oil can continue.

[0042] It should be noted that this solution needs to control the rotation speed of the gears so that the centrifugal force does not affect the state inside the elastic oil storage tank 6 and the extrusion mechanism.

[0043] The top view of the delivery pipe 11 is in an "n" shape, and the delivery pipe 11 is in contact with multiple surfaces of the corresponding gear teeth 4. Through the design of multiple capillary tubes 12, the lubricating fluid can flow out evenly through the multiple capillary tubes 12. The multiple capillary tubes 12 are respectively located on different surfaces, which can ensure the synchronous lubrication effect on various parts of the gear teeth 4.

[0044] The oil injection mechanism includes an oil injection pipe 7. The oil injection pipe 7 is fixedly connected to the elastic oil storage tank 6. The other end of the oil injection pipe 7 is fixedly installed with an oil injection port 13, and a blocking block 15 is arranged on the oil injection port 13.

[0045] The blocking block 15 can be installed in ways such as by threads and magnetism, but it is necessary to ensure the sealing effect of the gap at the connection between the blocking block 15 and the oil injection port 13 to ensure that the air pressure inside the elastic oil storage tank 6 can be changed, facilitating continuous oil output activities.

[0046] The connection part of the oil injection pipe 7 and the elastic oil storage tank 6 is at the upper end of the elastic oil storage tank 6, and the connection part of the output port 14 and the elastic oil storage tank 6 is at the bottom of the elastic oil storage tank 6. The design of the height makes the extruded lubricating oil can only be discharged through the output port 14, thus ensuring the delivery effect.

[0047] It should be noted that it is necessary to control the installation orientation of the gear so that the output port 14 is at the bottom to ensure the smooth outflow of the lubricating oil.

[0048] The working process of the present utility model: When in use, after installing the corresponding shaft body, first inject a sufficient amount of lubricating fluid inside, and then block the oil injection port 13 with the blocking block 15.

[0049] When the gears are meshed with each other, the contact block 5 will be squeezed, and then the contact block 5 can smoothly drive the extrusion plate 9 to move. The movement of the extrusion plate 9 will cause the elastic oil storage tank 6 to move, that is, the elastic oil storage tank 6 can be squeezed. The extruded lubricating oil flows out smoothly through the delivery pipe 11, and then flows out through the multiple capillary tubes 12. The multiple capillary tubes 12 are respectively located on different surfaces, which can ensure the synchronous lubrication effect on various parts of the gear teeth 4.

[0050] When not meshed, under the action of the spring 18, the moving rod 16 is pulled back to the side towards the fixed cylinder 17, so that the extrusion plate 9 does not contact the elastic oil storage tank 6. The elastic oil storage tank 6 returns to its original position under the action of its own elastic force, facilitating the next extrusion activity.

[0051] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
