Description

Technical Field

[0001] The present invention relates to the technical field of worm and worm gear reducers, and specifically to a worm and worm gear reducer with synchronous heat dissipation. Background Art

[0002] In the current industrial manufacturing field in China, with the rapid development of mechanical equipment towards high performance, high reliability, energy conservation and environmental protection, the worm and worm gear reducer, as a key mechanical transmission component, has an increasingly wide range of applications, covering many important industrial fields such as numerical control machine tools, automated production lines, mining machinery, and lifting equipment. However, there are some problems that need to be solved urgently in the actual application of traditional worm and worm gear reducers.

[0003] On the one hand, due to the tight meshing transmission between the worm and the worm gear, a large amount of heat will inevitably be generated during the power transmission process. This will not only lead to a decrease in the working efficiency of the equipment, but also the long-term high-temperature environment will accelerate the wear and aging of components, seriously affecting the service life and operation stability of the equipment.

[0004] On the other hand, the existing heat dissipation technologies are often relatively independent of the transmission system and fail to make full use of the operating power of the equipment itself. Usually, additional heat dissipation equipment and power sources are required, which not only increases the volume and weight of the equipment, but also raises the energy consumption and operating costs.

[0005] In addition, insufficient consideration is given to the coordination and synchronization of heat dissipation and lubrication, making it difficult to achieve an ideal heat dissipation effect. It is impossible to achieve dynamic and efficient heat dissipation and lubrication according to the actual working state of the equipment, thereby restricting the performance improvement of the entire mechanical equipment.

[0006] Therefore, in order to meet the urgent needs of the Chinese industrial manufacturing field for high-performance mechanical transmission equipment, improve the competitiveness of products, and promote industrial upgrading, a worm and worm gear reducer with synchronous heat dissipation is proposed to achieve efficient heat dissipation and lubrication functions, while taking into account structural compactness, energy conservation, and good coordination with the working state of the equipment, which is in line with the development trend of the transformation of Chinese manufacturing towards intelligence, greenness, and high efficiency.

[0012] Furthermore, the recovery gear (503) is in meshing contact with the bevel gear (201).

[0013] Furthermore, the heat dissipation device (6) includes a heat dissipation plate (601) fixedly installed above the housing (1), heat dissipation holes (602) are formed on the surface of the heat dissipation plate (601), a heat dissipation filter screen (603) is fixedly provided below the heat dissipation plate (601), a heat dissipation shaft (604) is movably clamped below the heat dissipation plate (601), heat dissipation blades (605) are fixedly provided on the surface of the heat dissipation shaft (604), and a wind wheel (606) is fixedly provided below the heat dissipation shaft (604).

[0014] Furthermore, the air outlet of the recovery pipe (505) faces the wind wheel (606).

[0015] The beneficial effects of this technical solution are as follows: (1) Through the circulating water pump in the circulating device, the lubricating fluid in the housing can be pumped from the water inlet pipe and sprayed through the water outlet pipe at the contact position between the worm gear and the worm, achieving effective lubrication of key components, reducing friction loss. During operation, the continuous spraying of the lubricating fluid can effectively reduce the heat generated by friction between components, thereby extending the service life of the components and ensuring the long-term stable operation of the equipment. At the same time, the meshing of the bevel gear and the pressurizing gear drives the pressurizing impeller to pressurize the lubricating fluid in the water inlet pipe, so that the lubricating fluid has a higher pressure when sprayed, further enhancing the lubrication and cooling effects, being able to carry away heat more effectively, improving the overall heat dissipation efficiency, and avoiding the decline in equipment performance or failure caused by overheating.

[0016] (2) By utilizing the meshing relationships of the bevel gear with the pressurizing gear and the recovery gear respectively, synchronous transmission is achieved. When the worm rotates, it can drive the pressurizing device and the recovery device to work together synchronously. This synchronous transmission design enables the actions of various components to be coordinated, improving the working efficiency of the equipment, avoiding energy loss and incoordination problems that may occur due to inconsistent working frequencies of different components, and enabling the entire heat dissipation and lubrication system to operate efficiently and stably.

[0017] (3) The recovery fan blades in the recovery device rotate driven by the recovery gear, generating wind and transmitting it into the recovery pipe. The outlet of the recovery pipe is a conical nozzle, making the wind more concentrated. This wind can drive the wind wheel in the heat dissipation device to rotate, and then drive the heat dissipation shaft and heat dissipation blades to rotate, promoting the dissipation of heat in the housing. This design realizes the recovery and reuse of energy. Through the transmission of wind, the energy that might otherwise be wasted is converted into the power to promote heat dissipation, improving the energy utilization efficiency and also contributing to enhancing the heat dissipation effect.

[0018] (4) The filter screen set under the inner wall of the housing can filter the lubricating fluid in the housing, preventing impurities from entering the circulation system, preventing the impurities from causing wear and blockage to each component during the circulation process, ensuring the cleanliness of the lubricating fluid, and extending the service life of each component. The heat dissipation filter screen under the heat dissipation plate in the heat dissipation device can prevent external dust and other impurities from entering the interior of the housing, protecting the internal components from the influence of external impurities, ensuring the stable operation of the equipment in different working environments, and reducing the risk of failures caused by the entry of impurities.

[0019] (5) The present invention integrates multiple functions such as lubrication, heat dissipation, and energy recovery in a worm and worm gear reducer, which has a compact structure, reduces the space required for equipment, and is convenient for installation and use in different mechanical systems. At the same time, the layout of each functional component is reasonable, and through ingenious transmission and connection methods, an organic whole is formed, reducing unnecessary component connections and pipeline arrangements, and lowering the complexity and maintenance cost of the equipment.

A pressure connecting rod 407 is fixedly arranged below the pressure shaft 405, and a pressure impeller 408 is fixedly arranged below the pressure connecting rod 407. The pressure impeller 408 is adapted to the inlet of the water inlet pipe 402. When in use, the worm 2 is connected to the external transmission structure. When the worm 2 starts to rotate, it will drive the circulating water pump 401 connected thereto to run. The circulating water pump 401 extracts the lubricating fluid in the housing 1 through the water inlet pipe 402, and sprays the lubricating fluid on the contact position between the worm wheel 3 and the worm 2 through the water outlet pipe 403, so as to achieve lubrication and cooling of the components, reduce the heat generated by friction, and ensure the normal operation of the equipment. At the same time, the bevel gear The wheel 201 is meshed with the pressurizing gear 406 and the recovery gear 503 respectively. When the worm 2 rotates, it drives the bevel gear 201 to rotate, and then drives the pressurizing gear 406 and the recovery gear 503 to rotate synchronously. The pressurizing gear 406 drives the pressurizing shaft 405 below to rotate, and the pressurizing shaft 405 further drives the pressurizing impeller 408 to rotate. In this process, the pressurizing impeller 408 will pressurize the lubricating fluid in the water inlet pipe 402. Since the lubricating fluid is pressurized, when it is sprayed on the contact position between the worm wheel 3 and the worm 2 through the water outlet pipe 403, it has better cooling and lubrication strength, can more effectively take away heat, and improve the lubrication and heat dissipation effects. A recovery device 5 is fixedly provided on the inner wall of the shell 1. The recovery device 5 includes a recovery plate 501 fixedly installed on the inner wall of the shell 1.

When the bevel gear 201 drives the recovery gear 503 to rotate, the recovery gear 503 drives the recovery shaft 502 to rotate, thereby rotating the recovery blade 504. The rotation of the recovery blade 504 generates wind force, and the wind force is transmitted to the recovery pipe 505. The air outlet of the recovery pipe 505 is a conical nozzle, which can make the wind force more concentrated. After the wind force is discharged from the air outlet, it will drive the wind wheel 606 in the heat dissipation device 6 to rotate.Above the housing 1, there is a heat dissipation device 6. The heat dissipation device 6 includes a heat dissipation plate 601 fixedly installed above the housing 1. The surface of the heat dissipation plate 601 is provided with heat dissipation holes 602. Below the heat dissipation plate 601, a heat dissipation filter screen 603 is fixedly provided. Below the heat dissipation plate 601, a heat dissipation shaft 604 is movably clamped. On the surface of the heat dissipation shaft 604, heat dissipation blades 605 are fixedly provided. Below the heat dissipation shaft 604, a wind wheel 606 is fixedly provided. The air outlet of the recovery pipe 505 faces the wind wheel 606. After the wind generated by the recovery fan blades 504 drives the wind wheel 606 to rotate, the wind wheel 606 drives the heat dissipation shaft 604 to rotate. The heat dissipation shaft 604 then drives the heat dissipation blades 605 to rotate. The rotation of the heat dissipation blades 605 can promote the air flow inside the housing 1 and accelerate the dissipation of heat. The heat can be discharged to the outside through the heat dissipation holes 602 on the heat dissipation plate 601. The heat dissipation filter screen 603 can prevent external impurities from entering the inside of the housing 1. Below the inner wall of the housing 1, a filter screen 7 is fixedly provided; First, install the worm and worm gear reducer with the same frequency heat dissipation on the required mechanical equipment, and ensure that the worm 2 is accurately connected to the external transmission structure. When the equipment starts, the external power is transmitted to the worm 2, causing it to start rotating. The worm 2 drives the circulating water pump 401 to start working. The circulating water pump 401 extracts the lubricating fluid inside the housing 1 through the water inlet pipe 402 and sprays it onto the contact position between the worm wheel 3 and the worm 2 through the water outlet pipe 403 to achieve initial lubrication and heat dissipation. At the same time, due to the meshing relationship between the bevel gear 201 and the pressurizing gear 406 and the recovery gear 503, the rotation of the worm 2 drives the bevel gear 201 to rotate, and then causes the pressurizing gear 406 and the recovery gear 503 to rotate synchronously. The pressurizing gear 406 drives the pressurizing shaft 405 to rotate, and finally drives the pressurizing impeller 408 to rotate, pressurizing the lubricating fluid in the water inlet pipe 402 and strengthening the spraying effect of the lubricating fluid, improving the lubrication and heat dissipation performance. The recovery gear 503 drives the recovery shaft 502 to rotate, and then drives the recovery fan blades 504 to rotate.

The wind wheel 606 drives the heat dissipation shaft 604 to rotate. The heat dissipation shaft 604 drives the heat dissipation blades 605 to rotate, thereby realizing the rapid discharge of heat inside the housing 1. The filter screen 7 below the inner wall of the housing 1 can filter the lubricating fluid inside the housing 1 to prevent impurities from affecting the lubrication and heat dissipation effects and ensure the long-term stable operation of the equipment; This co-frequency cooling worm and worm gear reducer organically combines the lubrication and cooling systems. The rotation of the worm 2 drives related components to work together, realizing the circulation, pressurization, spraying of the lubricating fluid and the effective dissipation of heat. The components cooperate skillfully through the transmission of the bevel gear 201, forming a complete cooling and lubrication system, solving the problems of the traditional worm and worm gear reducer in terms of lubrication and cooling. It has the advantages of compact structure, perfect function, good cooling and lubrication effects, and can be widely applied to various mechanical systems that require the use of worm and worm gear reducers and have high requirements for equipment performance and stability.
