Description

Technical Field

[0001] This utility model belongs to the field of gear technology, and relates to a gear, and more particularly to a self-lubricating gear. Background Technology

[0002] A gear is a mechanical component, typically used to transmit power and motion. It consists of two or more toothed teeth and is widely used in various equipment and machines, such as automobiles, airplanes, and machine tools.

[0003] Existing self-lubricating gears have a device containing lubricating oil inside the gear. When the gears mesh, the meshing teeth push open the device, allowing the lubricating oil to flow from inside the device to the meshing surface. This allows the gears to automatically lubricate, reducing lubricating oil loss, decreasing the frequency of lubricating oil replenishment, and extending the maintenance interval. However, there is a lack of a channel for replenishing lubricating oil. After the lubricating oil is exhausted, the staff has to replenish the lubricating oil into the device one by one, which increases the workload of maintaining the gears.

[0004] For example, a self-lubricating gear with application number 202322907179.6 includes a body and teeth. The teeth are provided with a sliding tooth meshing surface sliding block. The lubrication block is provided with a cavity. A through hole is provided on the side of the cavity near the body. An oil supply chamber is provided in the body. An oil supply hole is opened between the oil supply chamber and the lubrication block. A sealing ring is provided at the bottom of the oil supply hole. A lubrication groove is opened along the meshing surface of the teeth. The lubrication block can slide to the point where the hole and the lubrication groove are connected.

[0005] The aforementioned patent incorporates a lubrication device that allows the gear to output lubricating oil to lubricate the lubrication surface when meshing with other gears. The lubrication grooves ensure that the lubricating oil can fully lubricate the gear. However, the lubrication devices are independently installed inside the gears, making it inconvenient to replenish the gear with lubricating oil. Utility Model Content

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figures 1 to 4 As shown, this utility model can be implemented through the following embodiments: A self-lubricating gear includes a main body 1 and a cover 2. A fixing groove 11 is provided on the main body 1, and the cover 2 is installed in the fixing groove 11. The main body 1 is provided with teeth 12, and sliding grooves 121 are provided on both sides of the teeth 12. A sliding block 3 is installed in the sliding groove 121, and a return spring 4 is provided between the sliding block 3 and the sliding groove 121. An oil storage groove 122 is provided in the sliding groove 121, and an oil delivery hole 123 is provided at the bottom of the oil storage groove 122. An installation groove 13 is provided in the main body 1, and a support plate 131 is formed between the installation grooves 13. An oil delivery channel 14 is provided between the oil delivery hole 123 and the installation groove 13. An oil-absorbing sponge 5 is placed in the installation groove 13, and an oil injection hole 132 is provided in the installation groove 13. An oil injection plug 6 is installed on the oil injection hole 132.

[0022] The fixed groove 11 is used to install the cover 2. At the same time, the fixed groove 11 facilitates the opening of the installation groove 13 inside the gear, so that the installation groove 13 can be used to place the oil-absorbing sponge 5 and store lubricating oil. Sliding blocks 3 are set on both sides of the gear 12 to facilitate lubrication when the gear meshes during forward and reverse rotation. The sliding blocks 3 are used to block the sliding groove 121 to prevent lubricating oil leakage from the sliding groove 121. The oil storage tank 122 is used to store the lubricating oil delivered by the oil supply channel 14, so that the lubricating oil can lubricate in time when the gear meshes. The oil filling hole 132 and the oil filling plug 6 cooperate to ensure the sealing of the installation groove 13 while facilitating the replenishment of lubricating oil to the oil-absorbing sponge 5. The cover 2 is used to seal the installation groove 13 inside the fixed groove 11 to prevent the lubricating oil from flowing out of the fixed groove 11.

[0023] like Figure 1 and Figure 4As shown, the oil filling hole 132 and the oil filling plug 6 are connected by a threaded connection 61. The oil filling plug 6 is provided with a sealing convex ring 62 and an oil filling channel 63 is opened on the oil filling plug 6. A plug 64 is inserted into the oil filling channel 63. The threaded connection 61 between the oil filling hole 132 and the oil filling plug 6 can prevent the oil filling plug 6 from falling out of the oil filling hole 132 and improve the sealing performance between the oil filling plug 6 and the oil filling hole 132. The sealing convex ring 62 improves the sealing performance between the oil filling plug 6 and the oil filling hole 132 by creating a tortuous contact surface. The oil filling channel 63 and the plug 64 cooperate to allow the operator to inject lubricating oil into the oil-absorbing sponge 5 through the oil filling channel 63 by removing the plug 64.

[0024] like Figure 2 and Figure 3 As shown, the sliding groove 121 is provided with a stop 121a, and the sliding block 3 is provided with a corresponding limiting part 31. The stop 121a and the limiting part 31 cooperate to prevent the sliding block 3 from sliding out of the sliding groove 121, thereby reducing the possibility of lubricating oil leakage in the oil storage tank 122.

[0025] like Figure 2 and Figure 3 As shown, a step 7 is formed between the oil reservoir 122 and the sliding groove 121, and a sealing gasket 71 is provided on the step 7. The step 7 and the sealing gasket 71 cooperate to improve the sealing between the oil reservoir 122 and the sliding block 3, preventing lubricating oil from flowing out from the contact surface between the sliding block 3 and the oil reservoir 122 when the gear rotates.

[0026] like Figure 2 As shown, an arc-shaped plate 8 is installed inside the mounting groove 13, and a tension spring 81 is installed between the arc-shaped plate 8 and the mounting groove 13. The arc-shaped plate 8 abuts against the oil-absorbing sponge 5. When the gear rotates, the centrifugal force generated by the gear drives the arc-shaped plate 8 to move towards the tooth 12. The arc-shaped plate 8 and the mounting groove 13 squeeze the oil-absorbing sponge 5, and the oil in the oil-absorbing sponge 5 enters the oil storage tank 122 through the oil delivery channel 14.

[0027] like Figure 1 and Figure 2 As shown, the cover 2 is provided with a countersunk screw hole 22, and the fixing groove 11 is provided with a threaded hole 111. The cover 2 and the fixing groove 11 are provided with a sealing gasket 9. Countersunk bolts are inserted into the countersunk screw hole 22 and the threaded hole 111 to fix the cover 2 in the fixing groove 11; the sealing gasket 9 improves the sealing between the cover 2 and the fixing groove 11 and prevents lubricating oil from flowing out.

[0028] like Figure 1 As shown, a fixing plate 21 is provided on the cover 2, and a corresponding groove 15 is provided on the main body 1. A sealing gasket 3 10 is installed on the fixing plate 21. The fixing plate 21 cooperates with the groove 15, making the contact surface between the cover 2 and the main body 1 zigzag, thereby enhancing the sealing performance; the sealing gasket 3 10 further enhances the sealing performance between the cover 2 and the fixing plate 21.
