[0001] The utility model belongs to the technical field of gears, and specifically relates to a gear assembly that can prevent jamming. Background Technique

[0002] A gear assembly is an important component in a mechanical system, usually used to transmit power and motion. It consists of one or more gears that mesh with each other to change the direction, speed, and torque of rotation. Gear assemblies are widely used in various mechanical equipment, such as automobiles, machine tools, transmission systems, etc.

[0003] When the existing gear assembly operates inside the device, since multiple gears will generate friction when meshing with each other, this friction will not only cause energy loss but also accelerate the wear of the gear surface. Therefore, after long-term operation, the gears may jam due to excessive wear. Most existing devices generally add lubricating oil to the gears to reduce friction, but the coverage range of the added lubricating oil is relatively small, so it cannot fully cover all the gear surfaces that need to be lubricated, which may still cause jamming when the gear assembly is running. Therefore, a gear assembly that can prevent jamming is proposed to solve the problems raised in the background technique. Summary of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 4 shown, the present invention provides a gear assembly that can prevent jamming, including an outer box 1. Inside the outer box 1, there are an oil storage tank 2 and a square box 3. On one side of the oil storage tank 2, there is an oil delivery pipe 4 connected to the square box 3. At the top of the square box 3, a servo motor 6 is fixedly connected. Inside the square box 3, a turntable 7 and a square plate 11 are movably connected. On the surface of the turntable 7, circular grooves 8 are annularly and equally spaced at 180 degrees. At the top of the square plate 11, two circular rods 12 are fixedly connected. Inside the outer box 1, a first inclined block 13 and a second inclined block 15 are movably connected. On both sides of the first inclined block 13, first elastic pieces 14 fixedly connected to the outer box 1 are provided. Inside the second inclined block 15, a limit block 16 is movably connected. On the side of the limit block 16 away from the first inclined block 13, a second elastic piece 17 is fixedly connected. Inside the outer box 1, a hydraulic rod 18 and a button 19 are provided. At the bottom of the inner cavity of the outer box 1, a gear assembly body 20 is movably connected.

[0021] Adopting the above solution: The servo motor 6 drives the turntable 7 to rotate by 45 degrees, so that the circular groove 8 coincides with the oil outlet hole 9, and the sealing of the square box 3 is released. Then, it is convenient for the lubricating oil inside the square box 3 to flow into the nozzle 10. By the abutment of the inclined surface of the first inclined block 13 and the second inclined block 15, it is convenient for the second inclined block 15 to move and squeeze the first inclined block 13 downward, and then drive the square plate 11 to squeeze the lubricating oil inside the square box 3 to be sprayed onto the gear assembly body 20 through the nozzle 10, so as to achieve the lubricating effect on the gear assembly body 20, and then reduce the phenomenon of jamming that may occur during the operation of the gear assembly body 20.

[0022] As Figures 1 to 4As shown in the figure, an oil inlet pipe is provided at the top of the oil storage tank 2. A one-way valve 5 is provided inside the oil delivery pipe 4. The one-way valve 5 is used to allow the lubricating oil inside the oil storage tank 2 to flow unidirectionally into the inside of the square box 3. Oil outlet holes 9 are annularly arranged at 180 degrees at the bottom of the square box 3. The diameter of the oil outlet holes 9 is the same as that of the circular groove 8. The turntable 7 seals the oil outlet holes 9 in the initial state. The turntable 7 is composed of a disc and a cylinder. The output shaft end of the servo motor 6 is fixedly connected to the top of the cylinder. After the turntable 7 rotates, it drives the circular groove 8 to coincide with the oil outlet holes 9 and releases the seal of the square box 3.

[0023] Adopting the above scheme: Since an oil inlet pipe is provided at the top of the oil storage tank 2, it is convenient to supplement the lubricating oil inside the oil storage tank 2. Through the design of the one-way valve 5, it is used to prevent the lubricating oil from flowing back into the oil storage tank 2 through the oil delivery pipe 4 when the square plate 11 squeezes the lubricating oil inside the square box 3, thereby affecting the normal operation of the device.

[0024] As Figures 1 to 4 shown in the figure, one end of the first inclined block 13 and the second inclined block 15 opposite to each other are both bevel-shaped. One end of the second inclined block 15 away from the first inclined block 13 is fixedly connected to the hydraulic rod 18. The outer wall of the square plate 11 fits with the inner wall of the square box 3. The top of the round rod 12 penetrates the outer wall of the square box 3 and is fixedly connected to the first inclined block 13. The limiting block 16 is elastically connected to the second inclined block 15 through the second elastic sheet 17. After the second inclined block 15 moves towards the first inclined block 13, it drives the limiting block 16 to abut against the button 19.

[0025] Adopting the above scheme: Through the design of the second elastic sheet 17, its function is that when the hydraulic rod 18 drives the second inclined block 15 to always move towards the first inclined block 13, at this time, since the limiting block 16 abuts against the button 19, when the second inclined block 15 moves, the second elastic sheet 17 is squeezed, thereby ensuring the normal movement of the second inclined block 15. When the hydraulic rod 18 drives the second inclined block 15 to reset, the limiting block 16 releases the extrusion of the button 19. Subsequently, the limiting block 16 resets under the action of the elastic force of the second elastic sheet 17, which is convenient for the operator to use next time.

[0026] The working principle and use process of the utility model are as follows: the hydraulic rod 18 drives the second inclined block 15 to move toward the direction of the first inclined block 13 at a fixed time, so that during the movement of the second inclined block 15, the second spring piece 17 drives the limit block 16 to move toward the direction of the button 19, so that the side wall of the limit block 16 abuts against the button 19, so that the button 19 drives the servo motor 6 to operate. While the servo motor 6 rotates, it first drives the turntable 7 to rotate forty-five degrees clockwise, so that the turntable 7 drives the circular groove 8 to coincide with the oil outlet hole 9, thereby releasing the seal on the bottom of the square box 3, and then the hydraulic rod 18 drives the second inclined block 15 to continue to move, so that the inclined surface of the second inclined block 15 coincides with the inclined surface of the first inclined block 13. The first inclined block 13 is abutted against the second inclined block 15, and then the first inclined block 13 is pressed to move downward until the bottom of the second inclined block 15 is abutted against the plane of the top of the first inclined block 13. When the first inclined block 13 moves downward, the square plate 11 is driven to move inside the square box 3 through the round rod 12, so as to squeeze the lubricating oil inside the square box 3 to flow into the inside of the two nozzles 10 through the oil outlet 9. Subsequently, the pressure generated by the square plate 11 on the lubricating oil in the square box 3 is converted into kinetic energy, so that the lubricating oil is sprayed toward the gear assembly body 20 through the nozzle 10, and then the gear assembly body 20 is lubricated, so as to prevent the gear assembly body 20 from being stuck after a long period of operation, and thus improve the stability of the gear assembly body 20 during operation;

[0027] When the hydraulic rod 18 drives the second inclined block 15 to move in the opposite direction, the servo motor 6 drives the turntable 7 to rotate in the opposite direction by forty-five degrees, so that the turntable 7 re-seals the oil outlet 9. Subsequently, the second inclined block 15 releases the squeeze on the first inclined block 13, so that the first inclined block 13 is reset under the action of the pulling force of the first spring piece 14. While the first inclined block 13 is reset, the square plate 11 is driven upward by the round rod 12, so that the square plate 11 generates a pressure difference inside the square box 3, so that the lubricating oil inside the oil storage tank 2 is unidirectionally sucked into the inside of the square box 3 through the one-way valve 5, so as to replenish the lubricating oil inside the square box 3, so as to facilitate the next operation.

[0028] It is worth noting here that the servo motor 6 is rotated forty-five degrees clockwise through a servo driver and a corresponding control system, and then, when the hydraulic rod 18 is contracted, the servo motor 6 is rotated forty-five degrees counterclockwise. The above belongs to the prior art.
