Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically to a speed reducer oil temperature cooling structure. Background Technology

[0002] A speed reducer is a power transmission device that meets the operational requirements of mechanical equipment by reducing speed and increasing torque. Typically located between the power source and the working machine, the speed reducer plays a crucial role in mechanical transmission systems, matching speed and transmitting torque. It not only reduces speed and increases torque but also matches speed and torque, changes the direction of motion, and improves transmission efficiency and system stability.

[0003] Because the friction between gears generates heat during the operation of the speed reducer, it is necessary to cool the oil inside the speed reducer to prevent overheating and ensure the normal operation of the internal parts.

[0004] The cooling structure of a speed reducer is usually activated manually by workers or by a temperature sensor installed inside the equipment, which activates when the temperature rises. However, in actual use, the cooling mechanism may not operate in time, leading to an increase in the oil temperature inside the speed reducer, which causes a decrease in the performance of the lubricating oil and increases wear between gears, thus affecting the performance of the speed reducer. Utility Model Content

[0005] The purpose of this utility model is to provide a speed reducer oil temperature cooling structure to solve the problem mentioned in the background art that the cooling mechanism of the speed reducer is generally controlled by manual operation or temperature sensor to achieve on / off operation. This leads to the situation where the cooling mechanism is not opened in time during the operation of the speed reducer, resulting in high temperature inside the speed reducer, degrading the performance of the lubricating oil, increasing wear between gears, and affecting the operating effect of the speed reducer.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a reducer oil temperature cooling structure, comprising a body, wherein a connecting component for heat dissipation is provided on the outside of the body, the connecting component includes a mounting frame provided on the top of the body, two transmission wheels are provided inside the mounting frame, fan blades are provided on the outside of the two transmission wheels, and a connecting pipe is provided on the outer wall of the mounting frame; An extension frame is provided at the other end of the connecting pipe. A connecting rod and a vertical rod are provided inside the connecting pipe. A drive wheel is provided at one end of the connecting rod. A bevel gear is provided at the other end of the connecting rod and at one end of the vertical rod. A worm gear is provided at the other end of the vertical rod. A worm wheel is provided inside the extension frame. A telescopic rod is provided outside the worm wheel. A roller is provided at the other end of the telescopic rod.

[0007] Preferably, the mounting frame is connected to the top of the machine body by bolts, and has a hollow structure inside that communicates with the inside of the machine body. The two transmission wheel arrays are distributed on one side of the inner wall of the mounting frame and are rotatably connected to the inner wall of the mounting frame by a connecting shaft. The transmission wheels are coaxially connected to the fan blades.

[0008] Preferably, the connecting pipe has an L-shaped structure, and its two ends are respectively connected to the mounting frame and the extension frame. The connecting rod and the upright are located inside the two sections of the connecting pipe and are rotatably connected to the inner wall of the connecting pipe through bearings.

[0009] Preferably, one end of the connecting rod extends into the mounting frame and is connected to the drive wheel. The drive wheel is located inside the mounting frame, and its outer wall abuts and meshes with two transmission wheels inside the mounting frame.

[0010] Preferably, one end of the connecting rod and the top of the upright are engaged by a bevel gear, which links the connecting rod and the upright together, and the other end of the upright is coaxially connected to the worm gear.

[0011] Preferably, the worm gear is located inside the extension frame and is rotatably connected to the inner wall of the extension frame via a connecting shaft. One end of the telescopic rod is connected to the worm gear, and the other end extends to the outside of the extension frame and is coaxially connected to the roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting an additional mounting frame on the top of the reducer and installing fan blades inside the mounting frame, external airflow can be injected into the reducer through the rotation of the fan blades, thereby providing auxiliary cooling for the oil inside the reducer. Furthermore, the fan blades are separate from the original cooling mechanism inside the reducer, making it easy to disassemble and replace them. The fan blades can improve the cooling effect of the reducer during use on the basis of the original cooling mechanism, ensuring that the oil inside the reducer is kept at a low temperature and guaranteeing the normal operation of the reducer.

[0013] 2. The system is connected to the mounting frame via a connecting pipe, with an extension frame at the other end of the connecting pipe. A telescopic rod within the extension frame allows a roller to extend from the extension frame and reach the inside of the belt connected to the reducer, causing the roller to contact the belt. When the reducer drives the belt, friction causes the roller to rotate. Simultaneously, a worm gear, in conjunction with the upright rod, connecting rod, and gear structure, links the roller with the fan blades within the mounting frame. When the reducer drives the belt, it drives the fan blades, thus ensuring that the fan blade cooling mechanism and the reducer switch are synchronized, guaranteeing effective cooling of the internal oil when the reducer is on.

[0014] This invention utilizes an additional fan blade structure to assist in cooling the reducer, thereby improving the oil cooling effect. Furthermore, the fan blade mechanism is interlocked with the reducer's switch via a gear set, moving in sync with the reducer's operation to ensure that the internal oil remains cooled during reducer operation, thus guaranteeing the reducer's performance.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 A gear reducer oil temperature cooling structure includes a body 1. A connecting component for heat dissipation is provided on the outside of the body 1. The connecting component includes a mounting frame 2 on the top of the body 1. Two drive wheels 201 are provided inside the mounting frame 2. The drive wheels 201 are connected and linked with fan blades 3, so that when the drive wheels 201 rotate, they can drive the fan blades 3 to rotate synchronously. Fan blades 3 are provided on the outside of both drive wheels 201. When the fan blades 3 rotate, they can draw in the surrounding air and inject it into the gear reducer, thereby cooling the oil inside the gear reducer. A connecting pipe 4 is provided on the outer wall of the mounting frame 2.

[0019] The mounting frame 2 is connected to the top of the body 1 by bolts, and has a hollow structure inside that communicates with the inside of the body 1. Two drive wheels 201 are arrayed on one side of the inner wall of the mounting frame 2 and are rotatably connected to the inner wall of the mounting frame 2 by a connecting shaft. The drive wheels 201 are coaxially connected to the fan blade 3 on the outside.

[0020] In this embodiment: When in use, the mounting frame 2 can be used as an additional cooling mechanism and can be installed and removed from the reducer for easy replacement. The two transmission wheels 201 inside the mounting frame 2 abut against the drive wheel 501 on the inner wall of the mounting frame 2, so that when the drive wheel 501 rotates, it can drive the transmission wheel 201 and the fan blade 3 to rotate, thereby achieving cooling of the reducer.

[0021] Please see Figures 2-4 An extension frame 401 is provided at the other end of the connecting pipe 4. The extension frame 401 is positioned corresponding to the inner side of the belt at the front end of the reducer. A connecting rod 5 and a vertical rod 7 are provided inside the connecting pipe 4. A drive wheel 501 is provided at one end of the connecting rod 5. The drive wheel 501 is located inside the mounting frame 2 and is linked with the connecting rod 5. A bevel gear 6 is provided at the other end of the connecting rod 5 and one end of the vertical rod 7. The bevel gear 6 enables the connecting rod 5 and the vertical rod 7 to be linked. A worm 701 is provided at the other end of the vertical rod 7. The worm 701 abuts against a worm wheel 8 on one side, so that the worm 701 can be driven to rotate when the worm wheel 8 rotates. A worm wheel 8 is provided inside the extension frame 401. A telescopic rod 801 is provided outside the worm wheel 8. The telescopic rod 801 can adjust the extension range of the roller 9 so that the roller 9 can be fully in contact with the belt. A roller 9 is provided at the other end of the telescopic rod 801. The roller 9 abuts against the belt, so that the belt can drive the roller 9 to rotate through friction when the reducer drives the belt.

[0022] The connecting pipe 4 has an L-shaped structure, and its two ends are connected to the mounting frame 2 and the extension frame 401 respectively. The connecting rod 5 and the upright 7 are located inside the two sections of the connecting pipe 4 respectively, and are rotatably connected to the inner wall of the connecting pipe 4 through bearings. One end of the connecting rod 5 extends into the mounting frame 2 and is connected to the drive wheel 501. The drive wheel 501 is located inside the mounting frame 2, and its outer wall abuts and meshes with the two transmission wheels 201 inside the mounting frame 2. One end of the connecting rod 5 and the top of the upright 7 abut and mesh through the bevel gear 6, which makes the connecting rod 5 and the upright 7 move together. The other end of the upright 7 is coaxially connected to the worm gear 701. The worm gear 8 is located inside the extension frame 401 and is rotatably connected to the inner wall of the extension frame 401 through the connecting shaft. One end of the telescopic rod 801 is connected to the worm gear 8, and the other end extends to the outside of the extension frame 401 and is coaxially connected to the roller 9.

[0023] In this embodiment: during use, the telescopic rod 801 drives the roller 9 to extend from the extension frame 401 and extend to the inside of the belt. When the output end of the reducer drives the belt to run, the friction between the belt and the roller 9 can drive the roller 9 to rotate. At the same time, the roller 9 causes the telescopic rod 801 and the worm gear 8 to rotate. The worm gear 8 abuts against the worm 701, causing the upright rod 7 to rotate. At the same time, the bevel gear 6 causes the upright rod 7 to drive the connecting rod 5 to rotate. The drive wheel 501 at the other end of the connecting rod 5 abuts against the transmission wheel 201 on the inner wall of the mounting frame 2, thereby driving the transmission wheel 201 and the fan blade 3 to rotate. Therefore, when the reducer drives the belt conveyor to run, it can drive the fan blade 3 in the mounting frame 2, so that the fan blade 3 can be interlocked with the operation of the reducer to ensure that the reducer can cool the oil in the equipment when it starts.
