A lubrication cooling device for a speed reducer

Abstract

This utility model discloses a lubrication and cooling device for a speed reducer, relating to the field of speed reducer lubrication and cooling technology. It includes a speed reducer body, with a cooling assembly on one side of the body. The cooling assembly includes an oil pump installed on one side of the speed reducer body. This utility model filters sludge from the oil using a filter cloth, allowing the filtered oil to form a more uniform protective oil film on the worm gear and worm shaft surfaces, reducing the friction coefficient between them, decreasing waste oil disposal costs, and reducing the frequency of downtime for oil changes. By circulating water in an "S"-shaped flow pattern inside the cooling tank, the oil inside the annular pipe can be effectively cooled.

The cooled oil is sprayed out through nozzles, effectively allowing it to directly cool the worm and worm gear, improving the cooling efficiency of the speed reducer body.

Description

Technical Field

[0001] This utility model relates to the field of speed reducer lubrication and cooling technology, specifically to a lubrication and cooling device for speed reducers. Background Technology

[0002] Speed ​​reducers are common equipment in manufacturing. Used in conjunction with motors, speed reducers match the speed and transmit torque between the prime mover and the driven machine or actuator, aiming to reduce speed and increase torque. The lubricating oil in speed reducers primarily lubricates, cools internal components, cleans the reducer, seals it, prevents corrosion and oxidation, and also reduces noise and vibration.

[0003] A search of existing patents on the China Patent Network (publication number: CN207073566 U) reveals an external cooling device for lubricating oil in a speed reducer. One end of the cooling oil pipe is connected to the return oil pipe through an oil inlet, and the other end is connected to the inlet oil pipe through an oil outlet. This external cooling device for lubricating oil in a speed reducer greatly improves the cooling effect on the lubricating oil and extends the service life of the speed reducer.

[0004] However, the above technical solution still has certain defects. The device extracts the hot oil from the reducer, cools it through a cooling device, and then injects it back into the reducer to mix with the hot oil. During the mixing process, the temperature of the cooled oil will rise again. The heat generated in the reducer is caused by the high-speed rotation of the worm gear, which leads to its high temperature. As a result, the worm gear cannot be effectively cooled directly, reducing the cooling efficiency. Therefore, a lubrication and cooling device for reducers is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a lubrication and cooling device for a speed reducer to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lubrication and cooling device for a speed reducer, comprising a speed reducer body, wherein a cooling component is provided on one side of the speed reducer body;

[0007] The cooling assembly includes an oil pump installed on one side of the reducer body. A connecting pipe is provided on one side of the oil pump. A cooling box is installed at one end of the connecting pipe and at the bottom of the oil pump. An annular pipe fixed to the connecting pipe is provided inside the cooling box. Multiple sets of partitions are arranged longitudinally inside the cooling box. Circular grooves are opened on each of the multiple sets of partitions. A filter box is connected to the end of the annular pipe away from the connecting pipe. Two sets of connecting frames are installed inside the filter box. Filter cloth is provided in the connecting frames. An oil suction pipe extending into the reducer body is connected to one side of the top of the filter box. An oil outlet pipe is connected to the top of the oil pump. A U-shaped pipe is provided at one end of the oil outlet pipe. Nozzles are provided on both sides of the inner wall of the U-shaped pipe.

[0008] As a preferred technical solution, the top of the reducer body is provided with an oil injection hole, and a worm is installed inside the reducer body, with a meshing worm wheel at the bottom of the worm.

[0009] As a preferred technical solution, the cooling box is provided with an inlet pipe at the upper end of one side and an outlet pipe at the lower end of one side, and the inlet pipe and outlet pipe are connected to an external water source.

[0010] As a preferred technical solution, the circular grooves on the multiple sets of partitions are all mirrored.

[0011] As a preferred technical solution, the connecting frame is inclined and fixed to the inner wall of the filter box.

[0012] As a preferred technical solution, the nozzle is positioned directly opposite the meshing point between the worm and the worm wheel.

[0013] In summary, the present invention has the following main advantages:

[0014] This invention uses a filter cloth to filter sludge from the oil, allowing the filtered oil to form a more uniform protective oil film on the surfaces of the worm gear and worm shaft, reducing the coefficient of friction between them. It also reduces waste oil disposal costs and the frequency of downtime for oil changes. Water enters through the inlet pipe and flows out through the outlet pipe, circulating in an "S" shape within the cooling tank. This effectively cools the oil inside the annular pipe. The annular pipe also extends the time the oil spends inside the cooling tank, further improving cooling efficiency. The cooled oil is then sprayed out through nozzles, effectively cooling the worm and worm gear directly, thus improving the cooling efficiency of the reducer body. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A lubrication and cooling device for a speed reducer, such as Figure 1-6 As shown, it includes a reducer body 100, and a cooling assembly 200 is provided on one side of the reducer body 100;

[0026] The cooling assembly 200 includes an oil pump 210 installed on one side of the reducer body 100. A connecting pipe 220 is provided on one side of the oil pump 210. A cooling box 230 is installed at one end of the connecting pipe 220 and mounted at the bottom of the oil pump 210. An annular pipe 240 fixed to the connecting pipe 220 is provided inside the cooling box 230. Multiple sets of partitions 250 are arranged longitudinally inside the cooling box 230, and each set of partitions 250 has a circular groove 251. A filter box 260 is connected to the end of the annular pipe 240 away from the connecting pipe 220. The filter box 260 contains... Two sets of connecting frames 270 are installed, and filter cloth 280 is installed inside the connecting frame 270. The top side of the filter box 260 is connected to an oil suction pipe 290 extending into the reducer body 100. The top of the oil pump 210 is connected to an oil outlet pipe 2910. One end of the oil outlet pipe 2910 is provided with a U-shaped pipe 2920. Both sides of the inner wall of the U-shaped pipe 2920 are provided with nozzles 2930. The upper side of the cooling box 230 is provided with a water inlet pipe 231, and the lower side of the cooling box 230 is provided with a water outlet pipe 232. The water inlet pipe 231 and the water outlet pipe 232 are connected to an external water source.

[0027] When the reducer body 100 operates for an extended period, the internal oil temperature rises. The oil pump 210 is activated, drawing oil into the reducer body 100 via the oil extraction pipe 290. The oil then enters the filter box 260. As the oil passes through the filter cloth 280, it effectively filters out sludge, allowing the filtered oil to form a more uniform protective oil film on the surfaces of the worm gear 120 and worm 130, reducing the coefficient of friction between them. This also reduces waste oil disposal costs and the frequency of oil changes. When the oil passes through the filter cloth 280 and enters the annular pipe 240, an external water source enters the cooling box 230 through the water inlet pipe 231. The water source passes through the baffle 250 from the annular pipe... The water flows out of the trough 251 and into the next set of baffles 250, and finally flows out from the outlet pipe 232, so that the water source can circulate in the cooling box 230 in an "S" shape, which can fully cool the oil inside the annular pipe 240. At the same time, by setting the annular pipe 240, the oil can be extended in the cooling box 230, further improving the cooling efficiency. The cooled oil enters the U-shaped pipe 2920 through the oil outlet pipe 2910, and finally sprays out from the nozzle 2930, which can effectively cool the worm gear 120 and worm wheel 130 directly, improving the cooling efficiency of the reducer body 100.

[0028] Please refer to this carefully. Figure 1 , Figure 2 and Figure 5 The reducer body 100 has an oil injection hole 110 at the top and a worm gear 120 installed inside the reducer body 100. The worm gear 120 has a meshing worm wheel 130 at the bottom.

[0029] Oil can be added inside the reducer body 100 by setting the oil filling hole 110. By having the worm gear 120 and worm wheel 130 arranged in a 90-degree spatial staggered arrangement, the rotation direction of the input shaft can be changed to the vertical output direction.

[0030] Please refer to this carefully. Figure 3 The circular grooves 251 on the multiple sets of partitions 250 are mirrored, and the connecting frame 270 is fixed at an angle to the inner wall of the filter box 260.

[0031] By mirroring the circular groove 251, the water flow in the cooling box 230 can be made to flow in an "S" shape. By tilting the connecting frame 270, the sludge on the filter cloth 280 can be effectively made to slide off in the tilting direction.

[0032] Please refer to this carefully. Figures 4 to 6 The nozzle 2930 is positioned directly opposite the meshing point between the worm gear 120 and the worm wheel 130.

[0033] The cooling effect can be improved by positioning the nozzle 2930 directly at the meshing point between the worm gear 120 and the worm wheel 130.

[0034] During use, the oil pump 210 is started to draw oil into the reducer body 100, allowing the oil to enter the filter box 260. When the oil passes through the filter cloth 280, it effectively filters the sludge in the oil, enabling the filtered oil to form a more even protective oil film on the surfaces of the worm gear 120 and worm 130, reducing the coefficient of friction between them. This also reduces waste oil disposal costs and the frequency of downtime for oil changes. When the oil passes through the filter cloth 280 and enters the annular pipe 240, an external water source enters the cooling box 230 through the inlet pipe 231 and then flows out through the outlet pipe 232. The water source can circulate in an "S"-shaped flow pattern inside the cooling tank 230, which can effectively cool the oil inside the annular pipe 240. At the same time, by setting the annular pipe 240, the oil can be kept in the cooling tank 230 for a longer time, which further improves the cooling efficiency. The cooled oil is sprayed out through the nozzle 2930, which can effectively cool the worm gear 120 and worm wheel 130 directly, improving the cooling efficiency of the reducer body 100. The parts not mentioned in this device are the same as or can be implemented using existing technology.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
