Description

Technical Field

[0001] This invention relates to the field of mechanical engineering, specifically to a rotary reducer transmission gear shaft. Background Technology

[0002] A rotary reducer is a full-circuit rotary speed reduction transmission mechanism that integrates a drive power source. This type of device can be manufactured as a standard mechanical component and applied to various mechanical equipment with rotational requirements. In particular, this type of reducer has the advantages of high precision, compact structure, and large load-bearing capacity, making it suitable for use in relatively harsh working environments.

[0003] In gear transmissions, the meshing between the teeth generates secondary loads and friction, leading to tooth surface wear, stress, and decreased reliability. Tooth surface wear is caused by these secondary loads, and after prolonged operation, microscopic protrusions and depressions form on the tooth surface. Rotary reducers primarily utilize a worm gear structure, which features reverse self-locking and, compared to traditional gear transmissions, can achieve a relatively large reduction ratio. However, worm gear transmissions require greater contact force than other gear transmission structures, making them more prone to wear. Furthermore, the high heat and load generated during transmission accelerate the wear of the worm wheel and worm. Additionally, worm gear transmissions require the dissipation of some axial force during operation, making them more complex than gear transmissions and further increasing the likelihood of wear.

[0004] Meanwhile, particulate lubricating grease is also a significant factor leading to particulate matter in worm gear transmission systems. If the lubricating grease used in worm gear transmissions becomes particulate due to contamination, aging, or high temperatures, these particles may form particulate suspensions or even deposit on the surface of the transmission system, exacerbating equipment wear. Therefore, in practical applications, it is necessary to regularly and frequently replace the lubricating grease to ensure its cleanliness and to clean and maintain the transmission system in a timely manner.

[0005] However, when rotary reducers are used in confined or remote environments where maintenance is difficult, such as in wind turbines, the lubricating grease of the rotary reducer cannot be replaced regularly. This leads to the continuous accumulation of particles, which in turn exacerbates the wear between the worm gear and the worm. Since this wear further increases the amount of debris, a vicious cycle is formed, which damages the worm gear structure. Therefore, this situation will seriously affect the lifespan of the rotary reducer.

[0006] Therefore, a rotary reducer transmission gear shaft is proposed. Summary of the Invention

[0007] This invention provides a transmission gear shaft for a rotary reducer to solve the problem of excessive wear-induced debris particles within the rotary reducer, leading to continuous particle accumulation and accelerated wear. Specifically, as the worm rotates, it drives the slewing bearing to rotate, while a pushing assembly mounted on it moves the piston plate, pushing lubricating oil containing debris particles into a filter assembly for filtration. The filtered lubricating oil is then pumped back to continue lubricating the connection between the worm and the slewing bearing, ensuring that wear-induced particles do not affect the service life of the rotary reducer.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A rotary reducer transmission gear shaft includes: a drive housing, a support housing fixedly mounted on the drive housing, a slewing bearing rotatably connected inside the support housing, a worm gear rotatably connected inside the drive housing to drive the slewing bearing to rotate, and both the drive housing and the support housing are filled with lubricating oil, and a vent cap is installed on the drive housing.

[0010] When in use, the output shaft of the motor is fixed on the worm shaft. The rotation of the motor drives the slewing bearing to rotate through the worm. At the same time, the installed vent cap can prevent the lubricating fluid from expanding due to overheating inside the slewing reducer, which would damage the reducer.

[0011] A piston ring is slidably connected to the worm gear. A pushing assembly is installed at one end of the worm gear shaft to push the piston ring to reciprocate. The worm gear drives the pushing assembly to rotate. A storage cavity is provided at the end of the driving housing away from the pushing assembly. A connecting pipe is fixedly installed between one end of the driving housing and the supporting housing, and the connecting pipe communicates with the storage cavity. A one-way valve is fixedly installed on the connecting pipe. A filter assembly is installed between the storage cavity and the worm gear. A one-way flow unit is provided between the filter assembly and the worm gear, and the one-way flow unit is connected to the worm gear. A lubrication cavity is formed between the one-way flow unit and the piston ring. When the piston ring moves to one side, it pushes the lubricating oil in the lubrication cavity through the filter assembly into the storage cavity. When the piston ring moves to the other side, it draws the lubricating oil back into the lubrication cavity through the connecting pipe and the supporting housing.

[0012] The pushing assembly includes a limiting ring, a moving block, a slide rail, and a ball bearing. The limiting ring is fixedly installed inside the drive housing. The moving block, which is slidably connected to the limiting ring and sleeved on the worm gear, is fixedly installed on one side of the moving block with the piston ring. A slide rail is provided inside the moving block. A ball bearing is fixedly installed on the worm gear shaft and slides on the slide rail.

[0013] When the motor drives the worm to rotate, the rotating worm drives the slewing bearing to rotate, and the balls fixed on it also rotate. The rotating balls roll on the slide rail. When the balls slide to the top of the slide rail, because the moving block slides inside the limit ring, the rotating balls will not drive the moving block to rotate with them. Therefore, the balls will push the moving block to move closer to one side of the worm. When the balls slide to the bottom of the slide rail, the balls will push the moving block to move away from one side of the worm. At the same time, the moving moving block will push the piston ring to move. The moving piston ring will push the lubricating oil at the connection between the worm and the slewing bearing to one side for filtration. At the same time, the installed piston ring and moving block can improve the sealing effect inside the drive housing and prevent lubricating oil leakage.

[0014] The pushing assembly also includes a compression spring installed between the moving block and the limiting ring. The slide rail is arranged in a "Z" shape. When the worm rotates, it can smoothly push the piston ring to move and compress the compression spring. The worm continues to rotate. When the worm drives the ball to the corner of the "Z" shape, the slide rail and the worm are in a parallel state. At this time, the compressed spring will push the piston ring back to its original position. The compression spring can quickly push the hydraulic oil for filtration. The type of lubricating oil can be selected according to the type of lubricating oil used. When the density of the lubricating oil used is high, a wave-shaped slide rail can be used, while when the density of the lubricating oil used is low, a Z-shaped slide rail can be used. Both of the above structures can push the piston ring to move back and forth.

[0015] The filter assembly includes a storage block, a filter box, a filter screen, magnetic pillars, and magnetic strips. The storage block is fixedly installed inside the drive housing. The filter box is placed inside the storage block. The filter screen is fixedly installed inside the filter box. Multiple magnetic pillars are installed inside the filter box, and the magnetic pillars are rotatably connected to the inner wall of the filter box. Evenly arranged magnetic strips are fixedly installed on the magnetic pillars. The filter box is made of plastic.

[0016] The lubricating oil entering the filter box first passes through the magnetic column. Because the magnetic column is magnetic, it will attract metal debris in the lubricating oil, preventing the filter screen from being clogged due to excessive debris. When the magnetic column is in a fixed state, the flowing metal particles will only be attracted to the side of the magnetic column near the liquid inlet. The magnetic strip fixed on the magnetic column can rotate when the lubricating oil flows. The rotating magnetic column can make the flowing metal particles evenly adhere to it. Of course, the installed magnetic strip also makes the adsorption area wider.

[0017] The filter assembly also includes multiple magnetic plates fixedly installed inside the filter box, and the multiple magnetic plates are evenly arranged. During filtration, lubricating oil enters the filter box and passes between two adjacent magnetic plates. The magnetic plates on both sides adsorb the metal particles flowing through, thereby improving the filtration effect on metal particles. Different filter assemblies are selected according to the materials of the worm and slewing bearing. When the carbon content or other metal content of the worm and slewing bearing is high, magnetic columns can be used for auxiliary filtration. When there is too much metal material in the worm and slewing bearing that can be adsorbed by magnets, magnetic plates can be used for primary filtration.

[0018] The unidirectional flow unit includes a fixed ring, a rotating ring, and an arc-shaped connecting block. The fixed ring is fixedly installed inside the drive housing. The worm gear shaft is rotatably connected to the fixed ring. The rotating ring is fixedly installed on the worm gear shaft and is rotatably connected to the fixed ring. Both the fixed ring and the rotating ring have circular holes arranged in a ring. An arc-shaped connecting block is fixedly installed on one side of the fixed ring and is fixedly installed to the storage block. The arc-shaped connecting block, the fixed ring, and the rotating ring are all made of copper, and the magnetic force range of the magnet extends to the connection between the fixed ring and the rotating ring.

[0019] When the piston ring moves closer to the rotating ring on one side, the worm gear needs to rotate to drive the piston ring, and the rotating ring is fixed to the worm gear. Therefore, the rotating ring will rotate accordingly. Since both the fixed ring and the rotating ring have circular holes, these holes are tangent and overlap, allowing lubricating oil to pass through and enter the filter box. When the piston ring moves away from the rotating ring on one side, the circular holes on the fixed ring and the rotating ring are separated. This prevents the piston block from drawing lubricating oil from the storage chamber through the circular holes. Instead, the lubricating oil is drawn into the support housing through the connecting pipe, which better lubricates the slewing bearing inside the support housing. At the same time, because the magnetic force of the magnet extends to the connection between the fixed ring and the rotating ring, the magnetic force can attract metal particles, allowing them to pass smoothly through the circular holes into the filter box and preventing particles from accumulating on the rotating ring.

[0020] Meanwhile, because the one-way flow unit is a one-way structure, it can achieve the corresponding function through the one-way valve. However, because there are metal particles in the lubrication chamber, the metal particles will block the one-way valve, causing the one-way valve to be damaged. The rotating ring and the fixed ring that rotate with each other can achieve the one-way flow function and also prevent jamming.

[0021] Of course, the arc-shaped connecting block, the fixed ring, and the rotating ring are all made of copper, which not only increases the cooling effect inside the reducer, but also prevents the magnetic column from affecting the fixed ring and the rotating ring, and avoids metal particles from adsorbing on the rotating ring.

[0022] Both sides of the filter box are fixedly installed with snap-fit ​​blocks. The drive housing has an installation groove for installing the filter box. Both sides of the installation groove have snap-fit ​​slots that cooperate with the snap-fit ​​blocks. Conductive blocks are fixedly installed in the snap-fit ​​slots. The two conductive blocks are connected in series with the motor circuit that drives the worm gear to rotate. A metal plate connecting the two conductive blocks is fixedly installed on the snap-fit ​​block.

[0023] Because the conductive block is connected in series with the motor circuit, when the filter box is inserted into the storage block, the metal plate connects the conductive blocks on both sides, so that the motor driving the rotary reducer is energized. When the filter box is removed, the metal plate moves away from the conductive blocks on both sides, causing the circuit to break and the motor to stop operating normally. When the motor stops, the motor control program controls the motor shaft to rotate to a specified angle, so that the round hole on the rotating ring is misaligned with the round hole on the fixed ring, preventing lubricating oil with debris particles from entering the storage box after the filter box is removed.

[0024] A sealing membrane is fixedly installed on the side of the filter box near the arc-shaped connecting block. A magnetic ring is fixedly installed inside the sealing membrane. An iron ring that cooperates with the magnetic ring is installed on the arc-shaped connecting block. An inlet is opened on one side of the arc-shaped connecting block, and an outlet is opened on the other side of the arc-shaped connecting block. The area of ​​the outlet is smaller than the area of ​​the inlet.

[0025] Because the filter box is designed for easy removal, there is always a gap between the filter box and the storage box. When the filter box is pushed into the storage box, the magnetic ring will be attracted to the iron ring due to magnetic force. Since the magnetic ring is installed inside the sealing membrane, the sealing membrane will also be stretched and attracted to the arc-shaped connecting block, which increases the sealing effect between the filter box and the arc-shaped connecting block. This prevents the lubricating oil pushed in by the piston ring from flowing out from the gap at the connection between the filter box and the arc-shaped connecting block, thus improving the filtration effect of the filter box.

[0026] The drive housing contains a metal ball with a through hole. A flexible tube communicating with the through hole is fixedly installed on the metal ball, and the end of the flexible tube away from the metal ball is fixedly installed with the connecting pipe.

[0027] Because the rotary reducer can be used upright or laid down, and a vent cap is installed on one side of the storage chamber, preventing the piston rings from pushing the lubricating oil to fill the storage chamber, the lubricating oil is drawn into the support housing through the connecting pipe. However, if the lubricating oil does not cover the opening of the connecting pipe, the piston rings cannot draw the lubricating oil into the support housing by extraction. When the rotary reducer is used upright, the lubricating oil at the bottom of the storage chamber can be drawn through the hose. However, when the rotary reducer is laid down, the hose is set horizontally, causing the hose to not fall vertically to the bottom of the lubricating oil. A fixed metal ball ensures that the hose is always perpendicular to the ground, so that the hose is always inserted into the lubricating oil.

[0028] The connecting pipe is L-shaped, and the section of the connecting pipe near the support housing is tilted toward the drive housing.

[0029] When the worm gear drives the slewing bearing to rotate, the rotating slewing bearing will bring a small amount of debris into the connecting pipe. At the same time, the movement of the piston ring will also bring debris into the connecting pipe. It should be noted that the one-way valve is installed on the section of the connecting pipe near the bearing housing. At this time, the debris will be blocked at the position of the one-way valve. Of course, because one section of the connecting pipe is tilted towards the drive housing, the debris that enters the connecting pipe due to external force will return to the lubrication chamber of the drive housing due to gravity.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. This invention addresses the problem of excessive wear-induced debris particles in rotary reducers, which leads to continuous particle accumulation and exacerbates wear, thus ensuring the service life of the rotary reducer. Specifically, as the worm rotates, it drives the slewing bearing to rotate, and the piston plate moves through the push assembly installed on it. This pushes the lubricating oil containing debris particles into the filter box for filtration, and then the filtered lubricating oil is pumped back to continue lubricating the connection between the worm and the slewing bearing. This ensures that wear-induced particles do not affect the service life of the rotary reducer.

[0032] 2. Lubricating oil enters the drive housing through the connecting pipe and the support housing to lubricate the connection between the worm gear and the slewing bearing. Because it takes a certain amount of time for the lubricating oil to enter the drive housing, it first enters the support housing to lubricate the slewing bearing inside. Existing mechanisms use the rotation of the slewing bearing to bring the lubricating oil into the support housing for lubrication. However, by using the connecting pipe in conjunction with the lubricating oil, the lubricating oil can more comprehensively lubricate the slewing bearing, reducing wear and extending the service life of the slewing reducer.

[0033] 3. The worm gear drives the rotating ring to rotate, forming a unidirectional structure with the fixed ring. This not only prevents backflow of lubricating fluid into the storage chamber and prevents debris particles from interfering with the normal operation of the rotating and fixed rings, but also extends the magnetic force of the magnets installed in the filter box to the connection between the fixed and rotating rings. This magnetic force attracts metal particles, allowing them to pass smoothly through the channels formed by the round holes on the fixed and rotating rings and enter the filter box. This prevents particles from accumulating on the rotating ring, ensuring the normal operation of the filter assembly and extending the service life of the rotary reducer. Attached Figure Description

[0044] Please see Figures 1 to 9This invention provides a rotary reducer transmission gear shaft, the technical solution of which is as follows:

[0045] When the materials used to manufacture the worm gear 6 and the slewing bearing 5 have a low iron content: when the motor drives the worm gear 6 to rotate, the rotating worm gear 6 drives the slewing bearing 5 to rotate, and the ball bearing 15 fixed on it will also rotate. The rotating ball bearing 15 rolls on the slide rail 17. When the ball bearing 15 slides to the top of the slide rail 17, because the moving block 11 slides inside the limit ring 9, the rotating ball bearing 15 will not drive the moving block 11 to rotate with it. Therefore, the ball bearing 15 will push the moving block 11 to move closer to the worm gear 6 on one side. The moving block 11 pushes the piston ring 10 to move, and the moving piston ring 10 pushes the lubricating oil to move to one side.

[0046] A rubber ring 16 is fixedly installed on the side of the movable block 11 away from the piston ring 10, which is sleeved on the shaft of the worm 6. The rubber ring 16 increases the sealing effect of the rotary reducer.

[0047] When the piston ring 10 moves closer to the rotating ring 12 on one side, the worm 6 needs to rotate to drive the piston ring 10 to move, and the rotating ring 12 is fixed on the worm 6. Therefore, the rotating ring 12 will rotate accordingly. Since both the fixed ring 13 and the rotating ring 12 have round holes, the round holes on the fixed ring 13 and the rotating ring 12 are tangent and coincident, allowing the lubricating oil to pass through the round holes and enter the filter box 7.

[0048] Because it takes a certain amount of time for the lubricating oil to enter the drive housing 2, the lubricating oil will first enter the support housing 1 to lubricate the slewing bearing 5 inside the support housing 1.

[0049] The lubricating oil entering the filter box 7 first passes through the magnetic column 20. Because the magnetic column 20 is magnetic, it will attract metal debris in the lubricating oil, preventing the filter screen 19 from being clogged due to excessive debris. At the same time, because the magnetic column 20 is equipped with magnetic strips, the flowing lubricating oil will push the magnetic column 20 on both sides to rotate, so that the magnetic column 20 can evenly attract metal particles in the lubricating oil. The multiple magnetic strips installed also make the attraction range wider. Meanwhile, the filter screen 19 will filter particles that the magnet cannot attract. When performing maintenance, the filter box 7 is removed, and the debris particles stored in the filter box 7 are removed when changing the lubricating oil.

[0050] Of course, the filter box 7 is fixed inside the drive housing 2 by a knob. The filter box 7 is rotatably connected to a gear fixed to the knob. The filter box 7 has two sliding grooves, and a rack plate that meshes with the gear is slidably connected in each groove. The storage block 18 has holes that cooperate with the rack plate. When fixing the filter box 7, the knob is rotated, and the knob drives the gear to rotate. The rotating gear drives the rack plate into the hole, keeping the filter box 7 fixed. When removing the filter box 7, the knob is rotated to retract the rack plate into the sliding groove.

[0051] When the ball bearing 15 slides to the trough on the slide rail 17, the ball bearing 15 will push the moving block 11 to move away from the worm gear 6 on one side. At the same time, the moving moving block 11 will push the piston ring 10 to move. The moving piston ring 10 pushes the lubricating oil at the connection between the worm gear 6 and the slewing bearing 5 to one side for filtration. At this time, the piston ring 10 moves to the side away from the rotating ring 12. The round holes on the fixed ring 13 and the rotating ring 12 are in a state of separation, so that the piston block cannot draw the lubricating oil in the storage cavity through the round hole. The lubricating oil can only be drawn into the support housing 1 through the connecting pipe 3.

[0052] The connecting pipe 3 is connected to the drive housing 2 and the support housing 1 by welding. The connecting pipe 3 connected by welding is more robust. At the same time, the connecting pipe 3 is made of copper pipe, which can better dissipate heat from the lubricating oil in the rotary reducer.

[0053] When the materials used to manufacture the worm gear 6 and the slewing bearing 5 have a high iron content: a filter box 7 with a magnetic sheet mechanism is used, in which multiple magnetic sheets are evenly arranged and fixed inside the filter box 7. The moving piston ring 10 pushes the lubricating oil into the filter box 7. The lubricating oil entering the filter box 7 passes between two adjacent magnetic sheets. Because the materials of the worm gear 6 and the slewing bearing 5 have a high iron content, there are more iron particles generated by wear. At this time, the magnetic sheets arranged above and below can better attract the metal particles. At the same time, the sheet-shaped magnetic sheets can attract a wider area, which can better utilize the worm gear 6 and the slewing bearing 5 with high iron content.

[0054] Using a worm gear 6 to achieve reciprocating rotation results in significant axial and inertial forces, which not only wastes energy but also easily damages equipment and structures. Therefore, in practical applications, the worm gear 6 should be designed to rotate in a fixed direction to ensure its transmission efficiency and stability. However, in this invention, because the slewing bearing 5 rotates in one direction, and to improve the lubrication effect of the slewing bearing 5, [reference is needed]. Figure 1 When the slewing bearing 5 is used vertically, it can be driven to rotate clockwise. When the piston ring 10 draws lubricating oil into the bearing housing 1, the slewing bearing 5 will also rotate, and the rotation will make the lubricating oil cover the entire bearing housing 1.

[0055] The foregoing has described embodiments of the present invention. However, those skilled in the art can make various changes, modifications, and substitutions to the embodiments based on an understanding of the principles of the present invention. The scope of the present invention is defined by the claims and related content.
