Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, and specifically relates to a power-stabilized transmission structure for a gear reducer. Background Technology

[0002] A gear reducer is a power transmission device whose core function is to increase torque by reducing rotational speed, thereby converting the high-speed rotation of a motor or other drive equipment into a low-speed, high-torque output to meet the working requirements of mechanical equipment. When the operating frequency of a gear reducer approaches its natural frequency, a phenomenon called resonance occurs. Resonance leads to a significant increase in vibration amplitude, causing large relative displacement and impact forces during gear meshing, disrupting the normal tooth surface contact state, and potentially leading to transmission instability in the gear reducer. The conventional solution is to use vibration damping pads to absorb and reduce resonance. The advantage of this method is its simple structure, but its disadvantages are also obvious. Vibration damping pads can only effectively reduce vibration in gear reducers operating under low loads, but their damping effect is insufficient under high loads. Therefore, a new structure is proposed to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a power-stable transmission structure for a gear reducer, and solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a power-stabilized transmission structure for a gear reducer, comprising: a vibration damping component, wherein the vibration damping component includes a vibration damping cylinder for docking with a pressure block, a guide cylinder is provided on the inner side of the vibration damping cylinder, and a return spring is sleeved on the outer side of the guide cylinder;

[0005] The top of the pressure block is provided with a pressure plate for fixing to the bottom of the support plate, the bottom of the pressure block is provided with a magnetic cylinder, and the lower inner side of the guide cylinder is provided with a magnetic disk for repelling the magnetic cylinder with the same pole.

[0006] In a preferred embodiment, the reducer body is bolted to the top of the support plate, and a base plate is provided below the support plate, with four guide sleeves at the four corners of the top of the base plate.

[0007] In a preferred embodiment, four guide posts are provided at the four corners of the bottom of the support plate, the distance between the four guide posts matches the distance between the four guide sleeves, and the specifications of the guide posts match the specifications of the guide sleeves.

[0008] A limiting groove is provided on the inner side of the guide sleeve. The radius of the limiting groove is greater than the radius of the opening at the top of the guide sleeve. A limiting block is provided at the top of the guide post that matches the radius and depth of the limiting groove. Through the movable connection of the four guide posts and the guide sleeve, the support plate can be connected to the base plate on the one hand, and the vibration direction of the support plate can be limited on the other hand, so that the vibration is transmitted along the vertical direction, which helps the vibration damping component to absorb and weaken the vibration.

[0009] In a preferred embodiment, four sets of vibration damping components are equidistantly installed on the top of the base plate. Each vibration damping component includes a pressure plate and a vibration damping cylinder. The top of the pressure plate is glued to the bottom of the support plate, and the pressure block below the pressure plate is located inside and above the vibration damping cylinder.

[0010] In a preferred embodiment, the pressure block is made of stainless steel, the bottom of the pressure block is fixed to the top of the return spring, and the return spring is sleeved on the outside of the guide cylinder.

[0011] In a preferred embodiment, the height of the guide cylinder is less than the height of the return spring when it is under maximum compression, the height of the return spring is less than the depth of the damping cylinder, and the bottom of the damping cylinder is fixed to the top of the base plate by screws.

[0012] In a preferred embodiment, a magnetic cylinder is provided at the center of the bottom of the pressure block. The height of the magnetic cylinder matches the depth of the guide cylinder, and the radius of the magnetic cylinder matches the radius of the inner side of the guide cylinder.

[0013] In a preferred embodiment, the bottom of the magnetic cylinder and the top of the magnetic disk installed inside the lower part of the guide cylinder are opposite each other with the same pole. The outer side of the magnetic cylinder is wrapped with a stainless steel protective layer, and the outer side of the stainless steel protective layer is in contact with the inner side of the guide cylinder. The bottom of the magnetic cylinder and the top of the magnetic disk are always in a state of repulsion with the same pole, and the bottom of the magnetic cylinder and the top of the magnetic disk never come into contact. When the distance between the bottom of the magnetic cylinder and the top of the magnetic disk reaches the shortest limit, the return spring is compressed to the limit and begins to rebound. In this way, the magnetic repulsion force reduces the elastic potential energy of the return spring, thereby achieving the effect of vibration reduction, reducing the influence of resonance, and making the gear transmission more stable.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting up a vibration damping component, the vibration damping component includes a pressure block, a magnetic cylinder, a vibration damping cylinder, and a guide cylinder. The guide cylinder is located inside the vibration damping cylinder, and a return spring is sleeved on the outside of the guide cylinder. The pressure block is located above the inside of the vibration damping cylinder, and its bottom is fixed to the top of the return spring. The magnetic cylinder below the pressure block is located inside the guide cylinder, and the bottom of the magnetic cylinder and the top of the magnetic disk below the inside of the guide cylinder are opposite each other with the same pole. When the reducer body is working, it generates vibration. The vibration is transmitted downward to the four sets of vibration damping components through the support plate. The pressure plate drives the pressure block to move up and down along the inside of the vibration damping cylinder and repeatedly squeeze the return spring. At the same time, the magnetic cylinder and the magnetic disk inside the guide cylinder always maintain a state of repulsion between the same pole. Therefore, through the effect of repulsion between the same pole between the magnetic cylinder and the magnetic disk, the compression of the return spring can be buffered, the elastic potential energy of the spring can be reduced, thereby achieving the effect of vibration damping, reducing the influence of resonance, and making the gear transmission effect more stable.

[0015] 2. By setting guide pillars and guide sleeves, four sets of guide pillars are located inside four sets of guide sleeves, and the top of the guide pillar is equipped with a limiting block to limit the guide pillar inside the guide sleeve and prevent it from detaching from the inside of the guide sleeve. Through the setting of guide pillars and guide sleeves, the movement direction of the support plate can be limited, so that it can only vibrate in the vertical direction, thereby making the vibration transmission more thorough. In turn, the four sets of vibration damping components absorb the vibration more thoroughly, which helps to improve the absorption of vibration by the vibration damping components and thus helps to improve the stability of the gear transmission.

[0026] Please see Figures 1 to 4 A power-stabilizing transmission structure for a gear reducer includes: a vibration damping assembly 400, the vibration damping assembly 400 including a vibration damping cylinder 420 for docking with a pressure block 411, a guide cylinder 430 provided on the inner side of the vibration damping cylinder 420, and a return spring 421 sleeved on the outer side of the guide cylinder 430.

[0027] The top of the pressure block 411 is provided with a pressure plate 410 for fixing to the bottom of the support plate 200, the bottom of the pressure block 411 is provided with a magnetic cylinder 412, and the lower inner side of the guide cylinder 430 is provided with a magnetic disk 431 for repelling the magnetic cylinder 412.

[0028] The reducer body 100 is bolted to the top of the support plate 200. A base plate 300 is provided below the support plate 200. Four guide sleeves 310 are provided at the four corners of the top of the base plate 300.

[0029] The support plate 200 has four guide posts 210 at the four corners of its bottom. The distance between the four guide posts 210 matches the distance between the four guide sleeves 310. The specifications of the guide posts 210 match the specifications of the guide sleeves 310.

[0030] A limiting groove is provided on the inner side of the guide sleeve 310. The radius of the limiting groove is greater than the radius of the opening at the top of the guide sleeve 310. The top of the guide post 210 is provided with a limiting block that matches the radius and depth of the limiting groove. By the movable connection of the four guide posts 210 and the guide sleeve 310, the support plate 200 can be connected to the base plate 300 on the one hand, and the vibration direction of the support plate 200 can be limited on the other hand, so that the vibration is transmitted along the vertical direction, which helps the vibration damping component 400 to absorb and weaken the vibration.

[0031] Four sets of vibration damping components 400 are equidistantly installed on the top of the base plate 300. Each vibration damping component 400 includes a pressure plate 410 and a vibration damping cylinder 420. The top of the pressure plate 410 is glued to the bottom of the support plate 200, and the pressure block 411 below the pressure plate 410 is located inside and above the vibration damping cylinder 420.

[0032] The pressure block 411 is made of stainless steel. The bottom of the pressure block 411 is fixed to the top of the return spring 421, and the return spring 421 is sleeved on the outside of the guide cylinder 430.

[0033] The height of the guide cylinder 430 is less than the height of the return spring 421 when it is under extreme compression, the height of the return spring 421 is less than the depth of the damping cylinder 420, and the bottom of the damping cylinder 420 is fixed to the top of the base plate 300 by screws.

[0034] A magnetic cylinder 412 is provided at the center of the bottom of the pressure block 411. The height of the magnetic cylinder 412 matches the depth of the guide cylinder 430, and the radius of the magnetic cylinder 412 matches the radius of the inner side of the guide cylinder 430.

[0035] The bottom of the magnetic cylinder 412 and the top of the magnetic disk 431 installed inside the lower part of the guide cylinder 430 are opposite each other with the same pole. The outer side of the magnetic cylinder 412 is wrapped with a stainless steel protective layer, and the outer side of the stainless steel protective layer is in contact with the inner side of the guide cylinder 430. The bottom of the magnetic cylinder 412 and the top of the magnetic disk 431 are always in a state of repulsion with the same pole, and the bottom of the magnetic cylinder 412 and the top of the magnetic disk 431 never come into contact. When the distance between the bottom of the magnetic cylinder 412 and the top of the magnetic disk 431 reaches the shortest limit, the return spring 421 is compressed to the limit and begins to rebound. In this way, the magnetic repulsion force reduces the elastic potential energy of the return spring 421, thereby achieving the effect of vibration reduction, reducing the impact of resonance, and making the gear transmission more stable.

[0036] Example 1: Please refer to Figures 1 to 4In actual use, the bottom of the reducer body 100 is installed on the top of the support plate 200 by four sets of bolts. Below the support plate 200 is a base plate 300. Four sets of vibration damping components 400 are equidistantly installed on the top of the base plate 300. The vibration damping components 400 include a vibration damping cylinder 420 and a pressure plate 410. The top of the pressure plate 410 is glued to the bottom of the support plate 200. Below the pressure plate 410 is a stainless steel pressure block 411. A magnetic cylinder 412 is located at the center of the bottom of the pressure block 411. The outer side of the magnetic cylinder 412 is wrapped with a stainless steel protective layer. A guide cylinder 430 is provided in the center of the damping cylinder 420. A return spring 421 is sleeved on the outside of the guide cylinder 430. The top of the return spring 421 is fixed to the bottom of the pressure block 411, and the height of the return spring 421 after ultimate compression is greater than the height of the guide cylinder 430. A magnetic disk 431 is provided on the lower inner side of the guide cylinder 430. The radius and length of the magnetic cylinder 412 and the height match the radius and length of the inner side of the guide cylinder 430. The bottom of the magnetic cylinder 412 and the top of the magnetic disk 431 are repelled by the same pole and never come into contact.

[0037] When the reducer body 100 operates under high load, resonance occurs inside. This vibration reduces the stability of the gear transmission. Therefore, the vibration is transmitted downwards to the interior of the four sets of vibration damping components 400 via the load-bearing plate. First, the pressure plate 410 moves downwards, causing the pressure block 411 to move downwards along the inner side of the vibration damping cylinder 420. At the same time, the pressure block 411 compresses the return spring 421, causing it to contract and store force. Simultaneously, the magnetic cylinder 412 moves downwards along the guide cylinder 430 under the action of the pressure block 411. The repulsive force between the bottom of the magnetic cylinder 412 and the top of the magnetic disk 431 increases as the distance between them decreases. When the repulsive force reaches its maximum, the return spring... 421 stops contracting and begins to rebound upwards. It should be noted that vibration is wave-like, and the rebound of the return spring 421 occurs during the interval between two adjacent sets of vibrations. Therefore, as the vibration continues, the return spring 421 is repeatedly compressed and extended by the pressure block 411. As a result, the repulsive force between the magnetic cylinder 412 and the magnetic disk 431 can significantly reduce the elastic potential energy of the return spring 421, thereby effectively reducing the vibration transmitted from the pressure block 411. Subsequently, the vibration transmitted from the reducer body 100 can be effectively reduced through the four sets of vibration damping components 400, reducing the impact of resonance and significantly improving the stability of the gear transmission inside the reducer body 100.

[0038] Example 2: Please refer to Figure 2 and Figure 3The support plate 200 has four guide posts 210 at its four corners, and each guide post 210 has a limiting block at its top. The bottom plate 300 has four guide sleeves 310 at its four corners. Each guide sleeve 310 has a limiting groove on its inner side, and the radius and depth of the limiting groove match the radius and thickness of the limiting block. The radius of the limiting groove is greater than the radius of the opening at the top of the guide sleeve 310. The limiting block is used to limit the guide post 210 and prevent it from detaching from the guide sleeve 310. When the support plate 200 vibrates along with the reducer body 100, the four guide posts 210 move up and down along the inner side of the four guide sleeves 310. By moving the four guide posts 210 and the four guide sleeves 310 together, the movement direction of the support plate 200 is limited to the vertical direction. This greatly improves the vibration transmission efficiency and helps the four sets of vibration damping components 400 absorb and weaken the vibration, thereby improving the stability of the gear transmission.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
