[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0020] Example 1

[0021] See also Figure 1-2 A reducer lubrication device includes an oil storage tank 1 and a return pipe 2 on the reducer housing. The oil storage tank 1 has an oil inlet on the top, and an oil receiving plate 3 is rotatably connected to the other side of the oil inlet. A driving mechanism 4 for driving the oil receiving plate 3 to swing is fixedly connected to the outside of the reducer power shaft, and the driving mechanism 4 is located inside the reducer housing; one end of the return pipe 2 is fixed to the bottom of the reducer housing, and the other end of the return pipe 2 is located above the dry oil inlet.

[0022] The present application is a lubrication device arranged on a reducer. Through the setting of the return pipe 2, the lubricating oil inside the reducer can circulate and flow out at the bottom of the reducer housing. Then, it passes through the return pipe 2 and is discharged into the oil storage tank 1 through the oil inlet. After that, it is periodically opened through the oil receiving plate 3 and flows to various positions inside the reducer, effectively ensuring the smooth use of the device.

[0023] It also includes a peristaltic pump 5, which is driven by a reducer power shaft. The return pipe 2 includes an oil inlet pipe 201 and an oil outlet pipe 202. The end of the oil inlet pipe 201 is fixed to the bottom of the reducer housing, and the other end of the oil inlet pipe 201 is connected to the inlet of the peristaltic pump 5. One end of the oil outlet pipe 202 is connected to the outlet of the peristaltic pump 5, and the other end of the oil outlet pipe 202 is located on the oil inlet.

[0024] The device is provided with a peristaltic pump 5, which can synchronously provide power to the peristaltic pump 5 during the use of the reducer. After the peristaltic pump 5 is driven, the lubricating oil will be sucked in through the oil inlet pipe 201, and then the lubricating oil will be discharged through the oil outlet pipe 202 without the need for additional power.

[0025] Example 2

[0026] See also Figure 1-3A reducer lubrication device includes an oil storage tank 1 and a return pipe 2 on the reducer housing. The oil storage tank 1 has an oil inlet on the top, and an oil receiving plate 3 is rotatably connected to the other side of the oil inlet. A driving mechanism 4 for driving the oil receiving plate 3 to swing is fixedly connected to the outside of the reducer power shaft, and the driving mechanism 4 is located inside the reducer housing; one end of the return pipe 2 is fixed to the bottom of the reducer housing, and the other end of the return pipe 2 is located above the dry oil inlet.

[0027] The present application is a lubrication device arranged on a reducer. Through the setting of the return pipe 2, the lubricating oil inside the reducer can circulate and flow out at the bottom of the reducer housing. Then, it passes through the return pipe 2 and is discharged into the oil storage tank 1 through the oil inlet. After that, it is periodically opened through the oil receiving plate 3 and flows to various positions inside the reducer, effectively ensuring the smooth use of the device.

[0028] It also includes a peristaltic pump 5, which is driven by a reducer power shaft. The return pipe 2 includes an oil inlet pipe 201 and an oil outlet pipe 202. The end of the oil inlet pipe 201 is fixed to the bottom of the reducer housing, and the other end of the oil inlet pipe 201 is connected to the inlet of the peristaltic pump 5. One end of the oil outlet pipe 202 is connected to the outlet of the peristaltic pump 5, and the other end of the oil outlet pipe 202 is located on the oil inlet.

[0029] The device is provided with a peristaltic pump 5, which can synchronously provide power to the peristaltic pump 5 during the use of the reducer. After the peristaltic pump 5 is driven, the lubricating oil will be sucked in through the oil inlet pipe 201, and then the lubricating oil will be discharged through the oil outlet pipe 202 without the need for additional power.

[0030] The driving mechanism 4 includes a swing rod 6 rotatably connected to the reducer housing, the swing rod 6 is rotatably connected to the first connecting rod 7, the first connecting rod 7 is rotatably connected to the crankshaft 8, and the crankshaft 8 is arranged on the reducer power shaft. The bottom of the oil receiving plate 3 is rotatably connected to the second connecting rod 9, and the second connecting rod 9 is rotatably connected to the end of the first connecting rod 7.

[0031] The power shaft of the reducer can also synchronously drive the driving mechanism 4 to move. The crankshaft in the driving mechanism 4 is set on the power shaft of the reducer. When it rotates, it drives the first connecting rod 7 to move. Since the position of one end of the swing rod 6 is limited, it can only rotate, resulting in the upper end of the first connecting rod 7 showing a fixed movement trend, and through the second connecting rod 9, the oil receiving plate 3 is periodically opened to leak the oil downward.

[0032] The bottom of the oil storage tank 1 is also slidably connected to a slider 10, which is rotatably connected to the end of the first connecting rod 7 through a third connecting rod 11. The slider 10 is fixedly connected to an oil diffuser 12, which is located at the bottom of the oil storage tank 1 and is used to disperse the lubricating oil.

[0033] At the same time, under the action of the third connecting rod 11, the slider 10 slides back and forth synchronously, and drives the oil diffuser 12 to reciprocate at the bottom of the oil receiving plate 3. The oil receiving plate 3 can disperse the oil to various places inside the reduction gearbox through the oil diffuser 12 to ensure the lubrication effect.

[0034] A filter element for filtering the lubricating oil is also provided inside the oil storage tank 1. The provision of the filter element can effectively reduce impurities inside the lubricating oil and ensure the use effect of the lubricating oil.

[0035] Working principle:

[0036] The present application is a lubrication device for a speed reducer. The lubricating oil inside the speed reducer circulates through a return pipe 2, flowing out at the bottom of the speed reducer housing. The oil then flows through the return pipe 2 and into the oil reservoir 1 through the oil inlet. The oil receiving plate 3 then periodically opens, allowing the oil to flow to various locations within the speed reducer, effectively ensuring smooth operation of the device. The device is equipped with a peristaltic pump 5, which can synchronously power the speed reducer during operation. Once the peristaltic pump 5 is actuated, it draws lubricating oil through the oil inlet pipe 201 and then discharges it through the oil outlet pipe 202, eliminating the need for additional power. Furthermore, the speed reducer's power shaft can also synchronously drive a drive mechanism 4. The crankshaft in the drive mechanism 4 is mounted on the speed reducer's power shaft, and its rotation drives the first connecting rod 7. Because the swing arm 6 is limited in position at one end and can only rotate, the upper end of the first connecting rod 7 exhibits a fixed motion trend. The oil receiving plate 3 periodically opens via the second connecting rod 9, allowing the oil to leak downward. At the same time, under the action of the third connecting rod 11, the slider 10 slides back and forth synchronously, and drives the oil diffuser 12 to reciprocate at the bottom of the oil receiving plate 3. The oil receiving plate 3 can disperse the oil to various places inside the reduction gearbox through the oil diffuser 12 to ensure the lubrication effect.
