[0002] The reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery. The reducer matches the speed and transmits torque between the prime mover and the working machine or the actuator. It is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It has many types and models, and different types have different uses.

[0009] In a further embodiment, the input end of the heat exchange tube is fixedly connected to the output end of the oil guide tube, and the output end of the heat exchange tube is fixedly connected to the output end of the oil inlet pipe, so that the lubricating oil can be delivered into the heat exchange tube and exchange heat with the high-temperature lubricating oil through the cooling fins on the surface of the heat exchange tube.

[0010] In a further embodiment, the oil discharge assembly includes: a connecting pipe that passes through and is fixed between the reducer body and the lower tank, a filter screen is fixed to the middle end of the inner cavity of the connecting pipe; a bearing that is embedded in the central axis of the filter screen, a rotating paddle is fixed to the rotating end of the bearing; and a compression spring is arranged on both sides of the rotating paddle, a brush that fits the lower end surface of the filter screen is fixed to the upper end of the compression spring, so that the propeller can be driven to rotate by the flowing lubricating oil.

[0011] In a further embodiment, the rotating paddle is located below the filter screen and is used to drive the brush to scrape the lower end surface of the filter screen so that the brush can scrape the filter screen.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the lubricating oil in the reducer body can be introduced into the lower bin through the connecting pipe, and then introduced into the lubrication station through the oil outlet pipe. The lubrication station can introduce the lubricating oil into the cooling component through the oil guide pipe, and then send it back to the reducer body through the oil inlet pipe, which can form a recycling of lubricating oil, and the lubricating oil can be cooled through the heat exchange tube and a plurality of heat dissipation fins, changing the previous natural cooling method, improving the cooling effect, preventing the lubricating oil temperature from being too high, and failing to cool the speed change gear in the chassis, thereby improving the safe use of the reducer, and the electric fan can cool the heat dissipation fins with air cooling, so that the cooling effect of the heat dissipation fins is better.

[0017] 2. In the present invention, the pressure in the oil outlet pipe can be monitored by a pressure gauge.

[0018] 3. In the present invention, the lubricating oil discharged from the reducer body into the lower tank can be filtered through the filter to prevent impurities in the lubricating oil from clogging the electromagnetic control valve installed in the oil outlet pipe. When the lubricating oil flows into the lower tank through the connecting pipe, the flowing lubricating oil can drive the rotating paddle to rotate, so that the rotating paddle can accelerate the flow rate of the lubricating oil. At the same time, the rotating paddle drives the brush to scrape the filter to prevent the filter from being blocked.

[0019] 4. In the present invention, when the electromagnetic control valve closes the oil outlet pipe, the lubricant flowing into the lower tank from the reducer body accumulates in the lower tank, and the lubricant level rises, which can drive the floating plate to move upward, thereby attaching the sealing rubber plate to the output end of the connecting pipe, which can block the lubricant in the reducer body from flowing out, thereby preventing the loss of lubricant in the reducer body from causing damage to the reducer body gears.

[0032] Example 2

[0033] See also Figure 4, which is different from Example 1, is that: the oil discharge assembly 12 includes: a connecting pipe 1201 that passes through and is fixed between the reducer body 1 and the lower bin box 4, a filter screen 1202 is fixed at the middle end of the inner cavity of the connecting pipe 1201; a bearing 1203 that is embedded in the central axis of the filter screen 1202, and a rotating paddle 1204 is fixed at the rotating end of the bearing 1203; and compression springs 1205 are arranged on both sides of the rotating paddle 1204, and a brush 1206 that is in contact with the lower end surface of the filter screen 1202 is fixed at the upper end of the compression spring 1205.

[0034] Example 3

[0035] See also Figure 5 , which is different from Example 1, is that the closing component 13 includes: a slide groove 1301 opened on both sides of the inner cavity of the connecting pipe 1201, and a T-shaped slider 1302 is inserted into the inner cavity of the slide groove 1301; a connecting rod 1303 is arranged at one end of the two T-shaped sliders 1302 close to the center line of the connecting pipe 1201, and a floating plate 1304 is fixed to the extended end below the connecting rod 1303; and a sealing rubber plate 1305 is arranged on the surface of the floating plate 1304, and the sealing rubber plate 1305 is perpendicular to the center line of the connecting pipe 1201. When the oil outlet pipe 5 is closed, the lubricant level in the lower tank 4 rises, and the floating plate 1304 will move upward through the buoyancy, driving the sealing rubber plate 1305 to fit the output end of the connecting pipe 1201 to block it.

[0036] The working principle of the present invention is as follows: first, the lubricant in the reducer body 1 flows into the lower tank 4 through the connecting pipe 1201, and the filter 1202 in the connecting pipe 1201 filters the lubricating oil. The filtered lubricating oil flows into the lower tank 4 through the connecting pipe 1201, and the flowing lubricating oil drives the rotating paddle 1204 to rotate through the bearing 1203. The rotation of the rotating paddle 1204 accelerates the flow rate of the lubricating oil. At the same time, the rotating paddle 1204 drives the brush 1206 to scrape the filter 1202, and scrapes the impurities accumulated on the surface of the filter 1202. The lubricating oil in the lower tank 4 is sucked into the lubricating station 6 through the oil pump installed in the lubricating station 6, and then the lubricating oil in the lubricating station 6 is sent into the heat exchange tube 1106 through the oil guide pipe 9 by the oil pump. The lubricating oil is cooled in the heat exchange tube 1106 through a number of heat dissipating fins 1105 and an electric fan 1107, and then sent back to the reducer body 1 through the oil inlet pipe 10 to form a lubricating oil circulation system. The pressure in the oil outlet pipe 5 is monitored in real time by the pressure gauge 7. When the oil outlet pipe 5 is damaged and the pressure changes, the pressure gauge 7 transmits the monitoring data to the central control device. The central control device controls the electromagnetic control valve 8 to close the output end of the oil outlet pipe 5 to prevent the lubricating oil from flowing out. At this time, the lubricant level in the lower bin 4 rises, and the liquid level drives the floating plate 1304 to move upward. The floating plate 1304 fits the sealing rubber plate 1305 to the output end of the connecting pipe 1201, blocking the lubricant in the reducer body 1 from flowing out, thus completing the working principle of the present invention.
