Technical Field
[0001] This utility model belongs to the field of gear oiling technology, specifically relating to a single-channel open gear automatic oiling device. Background Technology
[0002] Gear meshing transmission is one of the main methods of mechanical transmission. Open gears are directly exposed to open working conditions and are easily corroded by external dust, water vapor, etc. Lubricating grease is the main way to maintain open gears. Traditional lubricating grease application is basically done manually, and the application effect is inconsistent and varies from person to person, making it impossible to achieve standardized lubrication. In addition, the equipment needs to be stopped when applying lubricating grease, which reduces the efficiency of equipment use and increases labor costs. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of the aforementioned technologies by providing a single-oil-channel automatic oil distribution device for large, heavy-load, low-speed open gears.
[0004] To achieve the above objectives, this utility model provides a single-channel open gear automatic oil distribution device, including a base and an oil distribution component. A sliding platform is connected to the base via a sliding component. A telescopic component is provided on the base, connecting to the sliding platform and capable of moving the platform back and forth. The oil distribution component includes an oil distribution block, a shaft, and a reset component. A cylindrical through-hole is formed on the oil distribution block, and the surface of the shaft conforms to the cylindrical through-hole. The oil distribution block is rotatable relative to the shaft. Two sealing rings are provided on the shaft, located on the upper and lower sides of the oil distribution block, respectively. A through-hole is provided on the sliding platform, and the inner wall of the through-hole is fixedly connected to the side of the shaft. An annular oil channel is formed inside the cylindrical through-hole, and the oil distribution block... A straight oil passage is provided, which is connected to an annular oil passage. The oil distribution block has a through channel, and a movable block is located within the through channel. The surface of the movable block is fitted against the inner wall of the through channel, and the movable block can slide left and right relative to the through channel. Two oil outlet notches are provided on the side of the movable block facing the cylindrical through hole, located on the left and right sides of the movable block respectively. The oil outlet of the straight oil passage is connected to the through channel. An oil injection channel is provided inside the shaft, and the oil outlet of the oil injection channel is connected to the annular oil passage. At least two return springs are provided, one end of which is fixedly connected to the sliding platform, and the other end is fixedly connected to the rear side of the oil distribution block. The reset component is used for the return of the oil distribution block to its original position.
[0005] Preferably, the base is gate-shaped, the telescopic component is located on the horizontal column of the base, and sliding components are provided on both vertical columns of the base.
[0006] Preferably, the sliding component includes a slide rail and a slider sleeved on the slide rail. The slider can move relative to the slide rail. The slide rail is fixedly connected to the base, and the slider is fixedly connected to the sliding platform.
[0007] Preferably, the telescopic component is a push rod.
[0008] Preferably, the bottom surface of the shaft and the bottom surface of the sliding platform are on the same horizontal plane.
[0009] Preferably, the oil inlet of the oil injection channel is located on the bottom surface of the shaft.
[0010] Preferably, the width of the vertical beam between the two oil outlet notches is greater than the diameter of the oil outlet.
[0011] Preferably, the oil-coating block is shaped like a toothed wheel.
[0012] Preferably, the number of reset components is at least two.
[0013] Preferably, the reset component is a return spring, with one end of the return spring fixedly connected to the sliding platform and the other end of the return spring fixedly connected to the rear side of the oiling block.
[0014] The beneficial effects of this utility model are as follows: 1. First, the base is fixedly installed on one side of the open gear to be oiled. The external oil supply pipe is connected to the oil inlet of the oil injection channel. The sliding platform is pushed towards the open gear through the telescopic component, so that the tooth part of the oil distribution block enters the tooth groove of the open gear. When the open gear rotates, it will drive the oil distribution block to rotate around the shaft at a certain angle. The tooth of the open gear will abut against the moving block and move it in the through channel, so that one of the oil outlets is connected to the straight oil channel. At this time, the grease in the oil injection channel first enters the annular oil channel, then enters the straight oil channel, and finally exits to the surface of the open gear through the oil outlet. When the open gear rotates in the opposite direction, the other oil outlet is connected to the straight oil channel, which can be matched with the rotation direction of the open gear to increase the applicable range. Two return springs are set so that the oil distribution block can automatically reset, thereby replenishing oil to multiple teeth of the open gear in sequence. In the natural state, the vertical beam of the moving block is manually pressed against the oil outlet, so no oil will come out.
[0015] 2. The grease is discharged sequentially through the oil injection channel, the annular oil channel, and the straight oil channel, which achieves uniform application of grease to the surface of the open gear to be lubricated. The method of applying grease while the open gear is running eliminates downtime, increases the effective working time of the equipment, solves the problem of poor results when applying grease manually in the traditional way, and also reduces labor costs and safety hazards.

A sliding platform 2 is connected to the base 1 via a sliding component. The base 1 also has a telescopic component connected to the sliding platform 2 and capable of moving the sliding platform 2 back and forth. The oil distribution component includes an oil distribution block 3, a shaft 4, and a reset component. The oil distribution block 3 has a cylindrical through hole 6, and the surface of the shaft 4 is fitted to the cylindrical through hole 6. The oil distribution block 3 can rotate relative to the shaft 4. The shaft 4 has two sealing rings 7, located on the upper and lower sides of the oil distribution block 3, respectively. The sliding platform 2 has a through hole 8, and the inner wall of the through hole 8 is fixedly connected to the side of the shaft 4. The cylindrical through hole 6... An annular oil channel 9 is provided inside the oil distribution block 3, and a straight oil channel 10 is provided inside the oil distribution block 3, which is connected to the annular oil channel 9. A through channel 11 is provided on the oil distribution block 3, and a movable block 12 is provided inside the through channel 11. The surface of the movable block 12 is set against the inner wall of the through channel 11, and the movable block 12 can slide left and right relative to the through channel 11. Two oil outlet notches 13 are provided on the side of the movable block 12 facing the cylindrical through hole 6, and the oil outlet notches 13 are located on the left and right sides of the movable block 12 respectively. The oil outlet 14 of the straight oil channel 10 is connected to the through channel 11. An oil injection channel 15 is provided inside the shaft body 4, and the oil outlet 16 of the oil injection channel 15 is connected to the annular oil channel 9. The reset member is used to return the oil distribution block 3 to its original position.
[0026] The base 1 is shaped like a gate, with the telescopic component located on the horizontal column of the base 1, and sliding components provided on both vertical columns of the base 1.
[0027] The sliding component includes a slide rail 17 and a slider 18 sleeved on the slide rail 17. The slider 18 can move relative to the slide rail 17. The slide rail 17 is fixedly connected to the base 1, and the slider 18 is fixedly connected to the sliding platform 2.
[0028] The telescopic component is a push rod 19, which drives the sliding platform 2 to move.
[0029] The bottom surface of the shaft 4 is on the same horizontal plane as the bottom surface of the sliding platform 2.
[0030] The oil inlet 20 of the oil channel 15 is located on the bottom surface of the shaft 4, which facilitates the installation of the external oil injection pipe.
[0031] The width of the vertical beam 21 between the two oil outlets 13 is greater than the diameter of the oil drain port 14, ensuring that the oil drain port 14 will not discharge oil when not in use.
[0032] The oil-cloth block 3 is shaped like a gear tooth, which allows it to better fit open gears.
[0033] The number of reset components is at least two. Each reset component is a return spring 5. One end of the return spring 5 is fixedly connected to the sliding platform 2, and the other end of the return spring 5 is fixedly connected to the rear side of the oiling block 3. The oiling block 3 can be reset by the return springs 5 on both sides when it rotates in the forward or reverse direction.
[0034] In use, the base 1 is first fixedly installed on one side of the open gear to be oiled. The external oil supply pipe is connected to the oil inlet 20 of the oil filling channel 15. The sliding platform 2 is pushed towards the open gear through the telescopic component, so that the gear teeth of the oil distribution block 3 enter the tooth groove of the open gear. When the open gear rotates, it will drive the oil distribution block 3 to rotate around the shaft 4 at a certain angle, and the gear teeth of the open gear will abut against the moving block 12, causing it to move within the through channel 11, so that one of the oil outlets 13 is connected to the straight oil channel 10. At this time, the oil is injected. The grease in oil passage 15 first enters the annular oil passage 9, then the straight oil passage 10, and finally exits through the oil outlet 13 to the surface of the open gear. When the open gear rotates in the reverse direction, another oil outlet 13 connects with the straight oil passage 10, which can be matched with the rotation direction of the open gear to increase the applicable range. Two return springs 5 are set to automatically reset the oil distribution block 3, thereby replenishing oil to multiple teeth of the open gear in sequence. In the natural state, the vertical beam 21 of the moving block 12 is manually pressed against the oil outlet 14, so no oil will be discharged.
[0035] The grease is discharged sequentially through the oil injection channel 15, the annular oil channel 9, and the straight oil channel 10, which achieves uniform application of grease to the surface of the open gear to be lubricated. The method of applying grease while the open gear is running eliminates downtime, increases the effective working time of the equipment, and solves the problem of poor results when applying grease manually in the traditional way. It also reduces labor costs and safety hazards.
