Description

Technical Field

[0001] This invention relates to the field of gear maintenance technology, specifically to an automatic grease application device for speed reducers. Background Technology

[0002] Gear reducers play a crucial role in industrial equipment, increasing torque by reducing output speed. Proper lubrication is essential to ensure their normal operation and extend their service life.

[0003] During use, a suitable grease should be selected. The selection of grease should be based on the working conditions of the gear reducer, such as temperature range, speed, and load. Before adding new grease, the inside of the reducer should be thoroughly cleaned and the old grease or lubricating oil removed. The amount of grease should be moderate. Too much grease will cause heat accumulation, while too little grease will not provide sufficient lubrication. For enclosed gear reducers, it is generally recommended to fill the bearing space to between 1 / 3 and 1 / 2. However, existing lubrication equipment is not convenient for controlling the amount of grease discharged, and manual adjustment by the operator is still required, which can easily lead to grease waste. Therefore, we propose an automatic grease application device for reducers to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic grease application device for speed reducers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic grease application device for speed reducers, comprising a mounting base, a receiving cavity disposed on the top of the mounting base, a limiting mechanism installed inside the receiving cavity, and auxiliary cleaning and lubrication mechanisms disposed on both sides of the receiving cavity, wherein a positioning cover is installed on the top of the receiving cavity, the positioning cover being located directly above the limiting mechanism, and the limiting mechanism being used for gear auxiliary limiting clamping;

[0006] The mounting base has sliding grooves at both ends. The auxiliary cleaning mechanism and the lubrication mechanism are both located inside the sliding grooves and are symmetrically arranged. The auxiliary cleaning mechanism and the lubrication mechanism can clean, maintain and lubricate the gears that are stuck on the limiting mechanism. During use, the reducer can be disassembled and the internal gear parts can be cleaned and maintained. When the gears are stuck inside the receiving cavity, they can be limited by the limiting mechanism. With the help of the auxiliary cleaning mechanism and the lubrication mechanism, they can be quickly cleaned and maintained, ensuring the processing efficiency of the equipment. The amount of grease can be adjusted according to the different gear models to avoid the need for secondary maintenance by the operator due to excessive or insufficient grease.

[0007] Preferably, the receiving cavity is used for auxiliary sealing to ensure the cleanliness of the processing environment. Rectangular grooves are provided at both ends of the receiving cavity, and the positions of the rectangular grooves correspond to the positions of the auxiliary cleaning mechanism and the lubrication mechanism, respectively.

[0009] Preferably, the limiting mechanism includes a positioning plate that is locked inside the storage cavity and a clamping tube that is rotatably disposed on the top of the positioning plate. The positioning plate is installed at the bottom of the inner wall of the storage cavity. The top of the positioning plate is provided with a circular groove. The clamping tube is rotatably disposed inside the circular groove. Multiple limiting frames are inserted inside the clamping tube. A pneumatic pipe is installed at the bottom of the positioning cover and is inserted inside the clamping tube to limit the limiting frames and thus clamp the gear.

[0010] Preferably, a snap-fit ​​rod is installed on the side wall of the positioning disk, a snap-fit ​​groove is opened at one end of the snap-fit ​​rod, an arc-shaped plate is installed between the snap-fit ​​rods, a docking plate is provided at the top of the snap-fit ​​rod, one end of the docking plate is arc-shaped, a clamping block is fixedly connected to the inner wall of the arc-shaped end of the docking plate, and the clamping block is snapped into the groove, a gap is provided between the bottom of the docking plate and the snap-fit ​​rod, and multiple adsorption shafts are installed at the top of the docking plate;

[0011] Multiple auxiliary positioning shafts are provided between the locking rods. The auxiliary positioning shafts are arc-shaped and are movably locked on the top of the arc-shaped plate. Multiple movable rollers are provided on the top of the auxiliary positioning shafts.

[0012] Preferably, the auxiliary cleaning mechanism includes a sealing baffle 1 movably disposed on the top of the mounting base and a rectangular frame locked inside the sealing baffle 1. The sealing baffle 1 is movably disposed inside a transmission groove on one side. An arc-shaped groove is opened inside the sealing baffle 1. The rectangular frame is locked inside the arc-shaped groove. A fixing groove is opened on the surface of the rectangular frame, and a buffer pressure plate is installed inside the fixing groove. The buffer pressure plate is provided with multiple arc-shaped rods, and multiple cleaning paddles are inserted on the arc-shaped rods for cleaning dirt in the gear gaps.

[0013] Preferably, the cleaning paddle has a rubber shaft on one side and is elastic, so that the cleaning paddle can be replaced individually after it is damaged, which can reduce maintenance costs.

[0014] Preferably, the lubrication mechanism includes a second sealing baffle and a movable shaft rotatably disposed inside the second sealing baffle. The second sealing baffle is movably engaged on the top of the mounting base. The second sealing baffle has an arc groove inside, and a movable frame is movably engaged inside the arc groove. The movable shaft is rotatably disposed inside the movable frame.

[0015] The movable shaft has a mesh-like interior. Multiple discharge plates are installed on the sidewalls of the movable shaft. The discharge plates have multiple fixing holes and are elastic. An arc-shaped pressure plate is provided between the discharge plates. Multiple transmission balls are movably inserted into the top of the movable shaft. A transmission shaft is installed at the bottom of the transmission balls. Multiple staggered elliptical plates are provided on the surface of the transmission shaft. The transmission shaft is rotatably disposed inside the arc-shaped pressure plate. A swing shaft is installed on the discharge plate. Multiple extrusion plates are provided on the swing shaft.

[0016] Preferably, the movable shaft has a fixing hole inside, and a storage tube is inserted into the fixing hole. A fixing cap is installed on the top of the storage tube. The middle section of the storage tube has a grid-like surface. Multiple movable rods are inserted into the storage tube. The movable rods correspond to the positions of the arc-shaped pressure plate. A pressure ring is installed between the inner walls of the movable rods. A compression shaft is opened on the surface of the pressure ring. The compression shaft is elastic and "V"-shaped. When the internal air pressure of the pressure ring changes, the angle between the compression shafts changes. The compression shaft abuts against the inner wall of the storage tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When applying grease to the gear gap, the present invention can adjust the movable shaft of different models according to the gear, so that the discharge plate and one side of the gear are staggered. During the movement, the angle of the extrusion plate can be adjusted according to the actual use needs, so that the extrusion plate is cross-shaped on one side of the discharge plate, and its included angle is less than the angle of the gear gap. This allows the grease to be adhered to the gear during the subsequent lubrication process, ensuring uniform feeding of the equipment and reducing the situation of excessive or insufficient feeding.

[0019] 2. The present invention can also be adjusted and maintained according to the size of the gear through the auxiliary positioning shaft, which plays a supporting role and is used for auxiliary positioning. When the gear rotates with the clamping tube, the bottom of the gear can abut against the top of the docking plate. It can clean one side of the gear during the transmission process to prevent debris and impurities from getting stuck between the moving rollers and ensure the operation process during maintenance.

[0020] 3. In this invention, a sealing baffle is placed against one side of the storage cavity. As the gear moves, the cleaning blade can squeeze and rub against the gap between the gear, which can quickly clean the inside. The generated debris can also fall onto the adsorption plate at the bottom, which is convenient for subsequent unified cleaning. The operator can observe the cleaning status of the gear through the rectangular groove on the other side, thereby ensuring the cleaning efficiency of the equipment.

[0021] 4. The present invention allows for the individual disassembly of the cleaning blade, enabling targeted replacement when localized wear occurs, thereby reducing maintenance costs;

[0022] 5. During the rotation of the movable shaft, the transmission ball can be squeezed against the inner wall of the movable frame, which in turn drives the transmission shaft to rotate. This squeezes the arc-shaped pressure plate, thereby causing the internal movable insert rod to move. This prevents air bubbles in the grease during the internal discharge process from causing uneven feeding. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-7The present invention provides a technical solution: an automatic grease application device for a speed reducer, comprising a mounting base 1, a receiving cavity 2 disposed on the top of the mounting base 1, a limiting mechanism 3 installed inside the receiving cavity 2, and an auxiliary cleaning mechanism 4 and a lubrication mechanism 5 disposed on both sides of the receiving cavity 2, and a positioning cover 21 installed on the top of the receiving cavity 2, the positioning cover 21 being located directly above the limiting mechanism 3, the limiting mechanism 3 being used for gear auxiliary limiting clamping;

[0033] The mounting base 1 has sliding grooves at both ends. The auxiliary cleaning mechanism 4 and the lubrication mechanism 5 are both located inside the sliding grooves. The auxiliary cleaning mechanism 4 and the lubrication mechanism 5 are symmetrically arranged. The auxiliary cleaning mechanism 4 and the lubrication mechanism 5 can clean, maintain and lubricate the gears that are stuck on the limiting mechanism 3. During use, the reducer can be disassembled and the internal gear parts can be cleaned and maintained. When the gear is stuck inside the receiving cavity 2, it can be limited by the limiting mechanism 3. With the help of the auxiliary cleaning mechanism 4 and the lubrication mechanism 5, it can be quickly cleaned and maintained to ensure the processing efficiency of the equipment. The amount of grease can be adjusted according to the different gear models to avoid the situation where there is too much or too little grease and the operator needs to perform secondary maintenance.

[0034] like Figure 2 As shown, in order to ensure the processing efficiency of the equipment, the storage cavity 2 is used for auxiliary sealing to ensure the cleanliness of the processing environment. Rectangular grooves are opened at both ends of the storage cavity 2, and the positions of the rectangular grooves correspond to the positions of the auxiliary cleaning mechanism 4 and the lubrication mechanism 5, respectively. The auxiliary cleaning mechanism 4 and the lubrication mechanism 5 can abut against both sides of the storage cavity 2 to clean and lubricate the gears.

[0035] A pair of dust collection plates are installed at the bottom of the inner wall of the storage cavity 2. The dust collection plates are used to absorb dust and debris generated during the cleaning process. The dust collection plates can be disassembled for cleaning, reducing the splashing of dust and oil during maintenance.

[0036] like Figure 3 As shown, in order to ensure the clamping effect of the device, the limiting mechanism 3 includes a positioning plate 31 that is locked inside the storage cavity 2 and a clamping tube 311 that is rotatably set on the top of the positioning plate 31. The positioning plate 31 is installed at the bottom of the inner wall of the storage cavity 2. The top of the positioning plate 31 is provided with a circular groove. The clamping tube 311 is rotatably set inside the circular groove. Multiple limiting frames are inserted inside the clamping tube 311. A pneumatic tube is installed at the bottom of the positioning cover 21 and is inserted inside the clamping tube 311. It is used to limit the limiting frames and thus clamp the gear. The pneumatic tube can be inserted inside the clamping tube 311 so that the limiting frames can abut against the inner wall of the gear. At the same time, the air pressure plays an adaptive role to avoid the situation of excessive or insufficient squeezing force during the clamping process.

[0037] To improve the positioning efficiency of the equipment, a snap-fit ​​rod 32 is installed on the side wall of the positioning disk 31. One end of the snap-fit ​​rod 32 is provided with a snap-fit ​​groove. An arc-shaped plate is installed between the snap-fit ​​rods 32. A docking plate 33 is provided on the top of the snap-fit ​​rod 32. One end of the docking plate 33 is arc-shaped. A clamping block is fixedly connected to the inner wall of the arc-shaped end of the docking plate 33 and the clamping block is snapped into the slot. There is a gap between the bottom of the docking plate 33 and the snap-fit ​​rod 32. Multiple adsorption shafts 331 are installed on the top of the docking plate 33.

[0038] Multiple auxiliary positioning shafts 34 are provided between the locking rods 32. The auxiliary positioning shafts 34 are arc-shaped and are movably locked on the top of the arc-shaped plate. Multiple movable rollers 35 are provided on the top of the auxiliary positioning shafts 34, which can press the auxiliary positioning shafts 34 against the bottom of the gear for auxiliary support. During the movement of the gear, the bottom can be squeezed between the bottom and the docking plate 33. The adsorption shaft 331 on the surface of the docking plate 33 can clean one side of the gear to prevent metal shavings or other debris from scratching the surface of the gear during maintenance and causing wear on the surface coating. As the docking plate 33 can swing slightly, the adsorption shaft 331 can deform and trap metal shavings or other debris in its gaps for easy collection and processing later.

[0039] like Figure 4 As shown, in order to reduce the residue of dirt and other contaminants in the gear gaps, the auxiliary cleaning mechanism 4 includes a sealing baffle 41 movably mounted on the top of the mounting base 1 and a rectangular frame 42 fitted inside the sealing baffle 41. The sealing baffle 41 is movably mounted inside one side of the transmission groove. An arc-shaped groove is opened inside the sealing baffle 41. The rectangular frame 42 is fitted inside the arc-shaped groove. A fixing groove is opened on the surface of the rectangular frame 42, and a buffer pressure plate 43 is installed inside the fixing groove. Multiple arc-shaped rods are provided on the buffer pressure plate 43, and multiple cleaning paddles 44 are inserted on the arc-shaped rods for cleaning dirt from the gear gaps. The sealing baffle 41 abuts against one side of the receiving cavity 2. As the gears move, the cleaning paddles 44 can squeeze and rub against the gear gaps, which can quickly clean the inside. The generated debris can also fall onto the adsorption plate at the bottom. The operator can observe the cleaning status of the gears through the rectangular groove on the other side and adjust the cleaning time according to different situations, thereby ensuring maintenance efficiency and quality.

[0040] To reduce costs during use, the cleaning paddle 44 is equipped with a rubber shaft on one side and is elastic, so that the cleaning paddle 44 can be replaced individually if it is damaged, thus reducing maintenance costs.

[0041] like Figure 5 and Figure 6As shown, it is necessary to avoid excessive or insufficient grease on the gears during maintenance. The lubrication mechanism 5 includes a second sealing baffle 51 and a movable shaft 53 rotatably disposed inside the second sealing baffle 51. The second sealing baffle 51 is movably locked on the top of the mounting base 1. The second sealing baffle 51 has an arc groove inside, and a movable frame 52 is movably locked inside the arc groove. The movable shaft 53 is rotatably disposed inside the movable frame 52.

[0042] The movable shaft 53 has a mesh-like interior. Multiple discharge plates 55 are installed on the sidewalls of the movable shaft 53. Each discharge plate 55 has multiple fixing holes and is elastic. An arc-shaped pressure plate 551 is positioned between the discharge plates 55. Multiple transmission balls 531 are movably inserted into the top of the movable shaft 53. A transmission shaft 56 is installed at the bottom of each transmission ball 531. Multiple staggered elliptical plates are provided on the surface of the transmission shaft 56. The transmission shaft 56 is rotatably mounted inside the arc-shaped pressure plate 551. A swing shaft 57 is installed on the discharge plates 55. Multiple extrusion plates 571 are provided on the swing shaft 57. 571 can be adjusted and pressed against the outer wall of the discharge plate 55. It can adjust the movable shaft 53 of different models according to the gear, so that the discharge plate 55 and one side of the gear are staggered. During the movement, the angle of the extrusion plate 571 can be adjusted according to the actual use requirements, so that the extrusion plate 571 is cross-arranged on one side of the discharge plate 55, so that its included angle is less than the angle of the gear side clearance. This allows the grease to adhere in the gear clearance, which not only ensures the stability of the feeding, but also controls the feeding amount and avoids excessive grease adhering in the gear clearance.

[0043] like Figure 7 As shown, air bubbles inevitably appear in the grease during the discharge process. The movable shaft 53 has a fixing hole inside, and a receiving tube 54 is inserted inside the fixing hole. A fixing cap 541 is installed on the top of the receiving tube 54. The middle section of the receiving tube 54 has a mesh-like surface. Multiple movable rods 58 are inserted into the receiving tube 54, and the movable rods 58 correspond to the positions of the arc-shaped pressure plate 551. A pressure ring 581 is installed between the inner walls of the movable rods 58. A compression shaft 582 is formed on the surface of the pressure ring 581. The compression shaft 582 is elastic and V-shaped. When the internal air pressure of the pressure ring 581 changes, it can compress the shaft 582. As the angle changes, the compression shaft 582 presses against the inner wall of the receiving tube 54. As the movable shaft 53 rotates, the transmission ball 531 is squeezed against the inner wall of the movable frame 52, causing the transmission shaft 56 to rotate. This squeezes the arc-shaped pressure plate 551, causing the internal movable insert rod 58 to move, preventing blockage during internal discharge. The internal air pressure of the air pressure ring 581 can be adjusted according to the actual situation to change the angle of the compression shaft 582, so that it moves in conjunction with the movable insert rod 58 during discharge, stirring the internal grease and preventing uneven discharge due to large air bubbles.

[0044] Working principle: First, during use, the reducer can be disassembled to clean and maintain the internal gear parts. When the gear is stuck inside the receiving cavity 2, it can be limited by the limiting mechanism 3. With the help of the auxiliary cleaning mechanism 4 and the lubrication mechanism 5, it can be quickly cleaned and maintained to ensure the processing efficiency of the equipment. The amount of grease can be adjusted according to the different gear models to avoid the need for secondary maintenance by the operator due to excessive or insufficient grease. When the gear is stuck on the clamping tube 311, the auxiliary positioning shaft 34 at the bottom can also be adjusted and maintained according to the size of the gear to provide support. At the same time, the pneumatic shaft is inserted inside the clamping tube 311 to push the clamping frame to be stuck on the inner wall of the gear for auxiliary clamping. When the gear rotates with the clamping tube 311, the bottom of the gear can abut against the top of the docking plate 33, which can clean one side of the gear during the transmission process to prevent debris and impurities from getting stuck between the movable rollers 35 and ensure the smooth operation during maintenance.

[0045] Then, when it is necessary to clean the gear gap, the sealing baffle 41 can be pressed against one side of the receiving cavity 2. As the gear moves, the cleaning disc 44 can squeeze and rub against the gear gap, which can quickly clean the inside. The generated debris can also fall onto the bottom adsorption plate for easy subsequent unified cleaning. The operator can observe the cleaning status of the gear through the rectangular groove on the other side, thus ensuring the cleaning efficiency of the equipment. The cleaning disc 44 can be disassembled separately and replaced when local wear occurs, thereby reducing maintenance costs.

[0046] Finally, when it is necessary to apply grease to the gear gap, the movable shaft 53 of different models can be adjusted according to the gear to make the discharge plate 55 staggered with one side of the gear. During the movement, the angle of the extrusion plate 571 can be adjusted according to the actual use requirements, so that the extrusion plate 571 is cross-shaped on one side of the discharge plate 55, and its included angle is less than the angle of the gear gap. This allows the grease to be applied to the gear during the subsequent lubrication process, ensuring uniform feeding of the equipment and reducing the situation of excessive or insufficient feeding. As the movable shaft 53 rotates, the transmission ball 531 can be squeezed against the inner wall of the movable frame 52, driving the transmission shaft 56 to rotate. This can squeeze the arc-shaped pressure plate 551, thereby causing the internal movable insert rod 58 to move and preventing blockage during the internal discharge process.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
