Description

Technical Field

[0001] The present application relates to the technical field of gears, and in particular to a low-noise mechanical operating gear. Background Art

[0002] At present, in the field of mechanical transmission devices, with the continuous improvement of industrial automation, the requirements for mechanical equipment are also getting higher and higher, especially in the precision processing and high-end manufacturing industries, which not only require mechanical equipment to have higher precision and stability, but also put forward more stringent requirements on its operating noise.

[0003] An existing patent (publication number: CN218882941U) discloses a low-noise automobile gear, including an automobile gear body, meshing teeth evenly installed on the outside of the automobile gear body, and lubricating oil circulation channels are provided inside the meshing teeth, and lubricating oil circulation channels are provided inside the lubricating oil blocking mechanism, and oil filling holes are evenly installed on the outside of the automobile gear body.

[0004] The above-mentioned comparative document points out that during the rotation of the automobile gear body, the device throws the lubricating grease in the lubricating oil storage tank into the main oil channel due to the action of centrifugal force, and pushes the blocking block downward, that is, the compression reset member is compressed, so that the lubricating oil flows out from the oil outlet and along the oil drain hole to the meshing teeth for lubrication. On the one hand, it reduces the friction and wear of the noise reduction mechanism during the meshing process, which helps to extend the service life of the automobile gear body. On the other hand, it reduces the noise generated by the gear teeth during the meshing process, which plays a noise reduction and protection effect. However, the device is not effective at low speeds. Under low rotation speed, due to the slow rotation speed, the centrifugal force generated is relatively small, resulting in the lubricating grease stored in the lubricating oil storage tank being difficult to be effectively thrown into the main oil channel. Therefore, the blocking block in the lubricating oil blocking mechanism may not be fully pushed, resulting in the lubricating oil being unable to flow out smoothly from the oil outlet and lubricate the meshing teeth. Since the lubricating oil is not thrown out smoothly at low speed, the meshing teeth may not be fully lubricated, which increases the friction and wear of the gears during the meshing process and reduces the transmission efficiency and service life of the gears. At the same time, lack of sufficient lubrication will also increase the noise generated by the gear teeth during the meshing process. Utility Model Content

[0005] In view of the deficiencies in the prior art, the low-noise mechanical operation gear provided by the present application has the advantages of reducing operation noise, etc., and solves the problem that, at low speed, the centrifugal force generated is relatively small due to the slow rotation speed, so that the lubricating grease stored in the lubricating oil storage groove is difficult to be effectively thrown into the main oil passage, thus the blocking block in the lubricating oil blocking mechanism may not be fully pushed, causing the lubricating oil to fail to flow out of the oil outlet hole and lubricate the meshing teeth, the meshing teeth may not be fully lubricated due to the poor throwing of the lubricating oil at low speed, increasing the friction and wear of the gear during meshing, reducing the transmission efficiency and service life of the gear, and the lack of sufficient lubrication also increases the noise generated by the gear teeth during meshing.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a low-noise mechanical operation gear, comprising a gear body and a plurality of pressing blocks, the gear body is internally provided with an oil storage cavity, the gear body is externally provided with a plurality of annularly arranged installation grooves, the inside bottom of each installation groove is fixedly connected with an air bag, the bottom of each pressing block is fixedly connected with a pressing plate, the bottom of each pressing plate is fixedly connected with a first spring, the inside of the gear body is fixedly connected with a plurality of annularly arranged oil outlet holes, one side of each oil outlet hole is fixedly connected with a support, the inside of each support is slidably connected with a sliding rod, one side of each sliding rod is fixedly connected with a sealing plate, one side of each oil outlet hole is fixedly connected with a baffle, the bottom of each baffle is fixedly connected with a second spring, and one end of each second spring away from the baffle is fixedly connected with the support.

[0007] Through the above-mentioned scheme, the device is designed with an internal oil storage cavity and oil outlet hole, cooperated with the air bag and pressing block structure, to realize an automatic lubrication mechanism, when the gear rotates, the pressing block is extruded to drive the pressing plate and the first spring to compress the air bag downward, to inject air into the oil storage cavity, so as to extrude the lubricating oil in the oil storage cavity through the oil outlet hole, to provide continuous lubrication for the gear, reducing the frequency of manual lubrication, and being able to automatically adjust the supply amount of lubricating oil according to the rotation speed of the gear, when the rotation speed of the gear increases, cooperating with the driven gear, the pressing block drives the pressing block to extrude the air bag more quickly, to inject more air into the oil storage cavity, to extrude more lubricating oil to meet the lubrication demand, improving the operation efficiency of the equipment, the setting of the oil outlet hole and the structure of the support, sliding rod and sealing plate connected therewith form an anti-backflow mechanism, when the pressure inside the oil storage cavity reaches a certain degree, the sealing plate is opened by the pressure, the lubricating oil flows out between the sealing plate and the baffle, the sealing plate is reset by the elastic force of the second spring, and the baffle cooperates with the sealing plate to seal the oil storage cavity, due to the good lubrication of the gear, the noise generated by friction is reduced, the continuous lubrication and uniform distribution of the lubricating oil help to reduce the wear of the gear and prolong the service life of the gear.

[0008] Furthermore, the bottom ends of the plurality of installation grooves are fixedly connected with four positioning columns arranged in a ring array, the inner walls of the plurality of pressure blocks are fixedly connected with two positioning seats on both sides, and the plurality of positioning columns are slidably arranged inside the positioning seats.

[0009] Through the above scheme, the positioning column at the bottom of the installation groove and the positioning seat on the inner wall of the pressure block slide together to ensure the precise positioning of the pressure block in the installation groove, which helps to maintain the stability of the pressure block during rotation and reduces noise and wear caused by shaking or misalignment.

[0010] Furthermore, three air inlet holes arranged in a linear array are provided on both sides of the outer walls of the plurality of pressing blocks.

[0011] Through the above solution, the air inlet is provided to provide air to the airbag during rotation.

[0012] Furthermore, the air outlet ends of the plurality of air bags extend into the oil storage cavity and are fixedly connected to a duckbill valve.

[0013] Through the above solution, the air outlet end of the airbag extends to the inside of the oil storage chamber and is fixedly connected to the duckbill valve, which prevents the lubricating oil from flowing back into the airbag, improves the efficiency and reliability of the lubrication system, and ensures that the gears are always fully lubricated during rotation.

[0014] Furthermore, a refueling hole is opened on one side of the gear body, a sealing cover is threadedly connected to the inside of the refueling hole, and a sealing ring is fixedly connected to one side of the sealing cover.

[0015] Through the above solution, the refueling hole opened on one side of the gear body provides the user with a convenient lubricating oil filling channel. The user can easily inject the lubricating oil into the oil storage chamber by opening the sealing cover without disassembling the entire gear device, which simplifies the maintenance process. The sealing cover threaded inside the refueling hole and the sealing ring fixedly connected on one side of the sealing cover together constitute a reliable sealing system. This design ensures that the lubricating oil will not leak from the refueling hole after filling, thereby maintaining the cleanliness and lubrication effect inside the gear device.

[0017] Through the above scheme, through stable spring support and effective airbag compression and release, the device can ensure that the lubrication system always maintains an efficient and stable working state during the gear rotation process.

[0018] Furthermore, the plurality of oil outlet holes are arranged in a Y shape.

[0019] Through the above scheme, the Y-shaped oil outlet hole can spray the lubricating oil onto the gear surface in a more dispersed and uniform manner when the gear rotates, which helps to reduce local friction and wear caused by uneven distribution of the lubricating oil, and improve the overall lubrication effect and service life of the gear. The design of the Y-shaped oil outlet hole increases the spray area and spray angle of the lubricating oil, so that the lubricating oil can more effectively cover the meshing surface and sliding surface of the gear, which helps to improve lubrication efficiency and reduce noise and vibration caused by insufficient lubrication.

[0020] Furthermore, the gear body is made of brass.

[0021] Through the above solution, the brass material has good wear resistance and corrosion resistance, and can maintain the stability and durability of the gear body in harsh working environments. The brass material has high strength and toughness and can withstand large loads and impact forces, which enables the gear device to maintain stable performance when bearing heavy loads or high-speed operation, and is not prone to deformation or breakage.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The invention relates to a low-noise mechanical running gear. The device realizes an automatic lubrication mechanism through the design of the built-in oil storage chamber and oil outlet hole, in conjunction with the air bag and pressure block structure. When the gear rotates, the pressure block is squeezed and drives the pressure plate and the first spring to compress the air bag downward, injecting air into the oil storage chamber, thereby squeezing the lubricating oil in the oil storage chamber through the oil outlet hole, providing continuous lubrication for the gear, reducing the frequency of manual lubrication, and being able to automatically adjust the supply of lubricating oil according to the rotation speed of the gear. When the gear rotation speed increases, it cooperates with the driven gear to make the pressure block drive the pressure block to squeeze the air bag more quickly, thereby injecting more oil into the oil storage chamber. More air can be squeezed out to squeeze out more lubricating oil to meet the lubrication needs, thereby improving the operating efficiency of the equipment. The setting of the oil outlet hole and the structure of the bracket, slide rod and sealing plate connected thereto form an anti-backflow mechanism. When the internal pressure of the oil storage chamber reaches a certain level, the sealing plate is pushed open to allow the lubricating oil to flow out from between the sealing plate and the baffle. The sealing plate is reset by the elastic force of the second spring and cooperates with the baffle to seal the oil storage chamber. Since the gears are well lubricated, the noise caused by friction is reduced. Continuous lubrication and uniform distribution of lubricating oil help reduce gear wear and extend the service life of the gears. BRIEF DESCRIPTION OF THE DRAWINGS

When the gear rotates, the pressure blocks 5 are squeezed and drive the pressure plates 6 and the first spring 7 to compress the air bags 4 downward, injecting air into the oil storage chamber 2, thereby squeezing the lubricating oil in the oil storage chamber 2 out through the oil outlet holes 8, providing continuous lubrication for the gear, reducing the frequency of manual lubrication, and improving the operating efficiency of the equipment. , multiple oil outlet holes 8 are fixedly connected to a bracket 9 on one side, multiple brackets 9 are slidably connected to slide rods 10 inside, multiple slide rods 10 are fixedly connected to a sealing plate 11 on one side, multiple oil outlet holes 8 are fixedly connected to a baffle 12 on one side, multiple baffles 12 are fixedly connected to the bottom ends of the second springs 13, and multiple second springs 13 are fixedly connected to the bracket 9 at one end away from the baffle 12. The arrangement of the oil outlet holes 8 and the structure of the bracket 9, slide rod 10 and sealing plate 11 connected thereto form an anti-backflow mechanism. When the internal pressure of the oil storage chamber 2 reaches a certain level, the sealing plate 11 is pushed open to allow the lubricating oil to flow out from between the sealing plate 11 and the baffle 12. The sealing plate 11 is reset by the elastic force of the second spring 13 and cooperates with the baffle 12 to seal the oil storage chamber 2.

[0033] See also Figure 2 、 Figure 4 and Figure 5 The bottom ends of the multiple mounting grooves 3 are fixedly connected to four positioning posts 14 arranged in a circular array, and both sides of the inner walls of the multiple pressure blocks 5 are fixedly connected to two positioning seats 15, and the multiple positioning posts 14 are slidably arranged inside the positioning seats 15. The positioning posts 14 at the bottom of the mounting grooves 3 slide with the positioning seats 15 on the inner wall of the pressure block 5 to ensure the precise positioning of the pressure block 5 in the mounting groove 3, which helps to maintain the stability of the pressure block 5 during rotation and reduces the noise and wear caused by shaking or misalignment. Three air inlet holes 16 arranged in a linear array are opened on both sides of the outer walls of the multiple pressure blocks 5. The air inlet holes 16 are set to provide air to the airbags 4 during rotation, and the air outlet ends of the multiple airbags 4 extend into the oil storage chamber 2 and are fixedly connected to a duckbill valve 17. The air outlet ends of the airbags 4 extend into the oil storage chamber 2 and are fixedly connected to the duckbill valve 17 to prevent the lubricating oil from flowing back into the airbags 4, thereby improving the efficiency and reliability of the lubrication system and ensuring that the gears are always fully lubricated during rotation.

[0034] See also Figure 1 、 Figure 2 and Figure 3The oil filling hole 18 is provided on one side of the gear body 1, and a sealing cover 19 is threadedly connected to the inside of the oil filling hole 18. A sealing ring 20 is fixedly connected to one side of the sealing cover 19. The oil filling hole 18 provided on one side of the gear body 1 provides a convenient lubricating oil filling channel for the user. The user can easily inject the lubricating oil into the oil storage chamber 2 by opening the sealing cover 19 without disassembling the entire gear device, which simplifies the maintenance process. The sealing cover 19 threadedly connected to the inside of the oil filling hole 18 and the sealing ring 20 fixedly connected to one side of the sealing cover 19 together constitute a reliable sealing system. This design ensures that the lubricating oil will not leak from the oil filling hole 18 after filling, thereby maintaining the cleanliness and lubrication effect of the gear device. The ends of the multiple first springs 7 away from the pressure block 5 are fixedly connected to the bottom of the mounting groove 3, and the ends of the multiple pressure plates 6 away from the pressure block 5 are fixedly connected to the upper end of the air bag 4. Through stable spring support and effective compression and release of the air bag 4, the device can ensure that the lubrication system can be lubricated during the rotation of the gear. In order to maintain an efficient and stable working state throughout the process, multiple oil outlet holes 8 are arranged in a Y shape. The Y-shaped oil outlet holes 8 can spray the lubricating oil to the gear surface in a more dispersed and uniform manner when the gear rotates, which helps to reduce local friction and wear caused by uneven distribution of the lubricating oil, and improve the overall lubrication effect and service life of the gear. The design of the Y-shaped oil outlet holes 8 increases the spray area and spray angle of the lubricating oil, so that the lubricating oil can more effectively cover the meshing surface and sliding surface of the gear, which helps to improve the lubrication efficiency and reduce the noise and vibration caused by insufficient lubrication. The gear body 1 is made of brass, which has good wear resistance and corrosion resistance and can maintain the stability and durability of the gear body 1 in harsh working environments. The brass material has high strength and toughness and can withstand large loads and impact forces, which enables the gear device to maintain stable performance when subjected to heavy loads or high-speed operation, and is not prone to deformation or breakage.

[0035] In this embodiment, a low-noise mechanical running gear is provided. The device realizes an automatic lubrication mechanism through the design of the built-in oil storage chamber 2 and the oil outlet hole 8, in conjunction with the air bag 4 and the pressure block 5 structure. When the gear rotates, the pressure block 5 is squeezed to drive the pressure plate 6 and the first spring 7 to compress the air bag 4 downward, injecting air into the oil storage chamber 2, thereby squeezing the lubricating oil in the oil storage chamber 2 through the oil outlet hole 8, providing continuous lubrication for the gear, reducing the frequency of manual lubrication, and being able to automatically adjust the supply of lubricating oil according to the rotation speed of the gear. When the gear rotation speed increases, it cooperates with the driven gear to make the pressure block 5 drive the pressure block 5 to squeeze the air bag 4 more quickly, thereby injecting air into the oil storage chamber 2. More air squeezes out more lubricating oil to meet the lubrication needs, thereby improving the operating efficiency of the equipment. The setting of the oil outlet hole 8 and the structure of the bracket 9, slide rod 10 and sealing plate 11 connected thereto form an anti-backflow mechanism. When the internal pressure of the oil storage chamber 2 reaches a certain level, the sealing plate 11 is pushed open to allow the lubricating oil to flow out from between the sealing plate 11 and the baffle 12. The sealing plate 11 is reset by the elastic force of the second spring 13 and cooperates with the baffle 12 to seal the oil storage chamber 2. Since the gears are well lubricated, the noise caused by friction is reduced. Continuous lubrication and uniform distribution of lubricating oil help reduce gear wear and extend the service life of the gears.

[0036] It should be noted that the device can automatically adjust the supply of lubricating oil according to the rotation speed of the gear. When the rotation speed of the gear increases, it cooperates with the driven gear to make the pressure block 5 drive the pressure block 5 to squeeze the airbag 4 more quickly, thereby injecting more air into the oil storage chamber 2 and squeezing out more lubricating oil to meet the lubrication needs. When the internal pressure of the oil storage chamber 2 increases to a certain level, the lubricating oil will push the sealing plate 11 to overcome the elastic force of the second spring 13 and open, and flow out from the gap between the sealing plate 11 and the baffle 12. When the pressure decreases, the second spring 13 resets the sealing plate 11 to ensure that the lubricating oil does not flow back into the oil storage chamber 2.

[0037] The working principle of the above embodiment is:

[0038] First, open the filling hole 18 by rotating the sealing cover 19, inject lubricating oil into the oil storage chamber 2, and close the sealing cover 19. The sealing cover 19 threadedly connected to the inside of the filling hole 18 and the sealing ring 20 fixedly connected to one side of the sealing cover 19 ensure that the lubricating oil will not leak from the filling hole 18 after filling. When the gear starts to rotate, the pressure block 5 is subjected to the matching pressure with the driven gear, driving the pressure plate 6 and the first spring 7 to compress the airbag 4 downward. When the airbag 4 is compressed, the air inside it enters the oil storage chamber 2 through the duckbill valve 17, increasing the pressure in the oil storage chamber 2. As the pressure in the oil storage chamber 2 increases, when the internal pressure of the oil storage chamber 2 increases to a certain level, the lubricating oil pushes the sealing plate 11 to overcome the second spring 13 The second spring 13 resets the sealing plate 11 to prevent the lubricating oil from flowing back into the oil storage chamber 2. The device can automatically adjust the supply of lubricating oil according to the rotation speed of the gear. When the gear rotation speed increases, the pressure block 5 drives the pressure block 5 to squeeze the airbag 4 more quickly, thereby injecting more air into the oil storage chamber 2 and squeezing out more lubricating oil to meet the lubrication needs. Since the gear is well lubricated, the noise caused by friction is reduced.
