Description

Technical Field

[0001] This utility model relates to the field of damper technology, specifically a worm gear drive type damper. Background Technology

[0002] While some existing dampers employ worm gear drives for damping, these structures have significant drawbacks in practical applications. When the worm gear is designed to be quite long, excessive driving force is generated during the worm wheel drive process. This force directly impacts the internal components of the damper, easily leading to deformation, wear, or even complete damage, severely affecting its service life and operational stability. Furthermore, to achieve the buffering effect between the damper and the worm gear, existing technologies often employ tool-assisted fixing or integrated molding connections. However, tool-assisted installations are prone to loosening after prolonged use, and both integrated and tool-mounted structures present inconveniences for later maintenance. When the damper or worm gear malfunctions, effective disassembly and replacement are impossible, necessitating complete scrapping and increasing operating costs and resource waste.

[0003] Therefore, it is necessary to develop a worm gear drive damper. Utility Model Content

[0004] The purpose of this invention is to provide a worm gear drive damper to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a worm gear drive damper, comprising a damper, an output shaft mounted at one end of the damper, and a guide ring mounted on one side of the outer wall of the damper; A worm gear drive auxiliary assembly is installed on one side of the damper. The worm gear drive auxiliary assembly includes a worm, and a worm wheel is installed above the worm.

[0006] Preferably, a pin is installed at one end of the output shaft, and a threaded hole A is provided at the center of the pin.

[0007] Preferably, the teeth on the worm gear mesh with the teeth on the worm, and a socket is installed at one end of the worm.

[0008] Preferably, a threaded hole B is provided at the center of the socket, and a stud is installed inside the threaded hole B.

[0009] Preferably, the outer wall of the stud is threadedly connected to the inner thread of the threaded hole B, and a nut is threadedly connected to the lower part of the outer wall of the stud.

[0010] Preferably, the nut is located below the socket, and a buffer ring is installed at one end of the socket, with the outer wall of the buffer ring slidably connected to the outer wall of the output shaft.

[0011] Preferably, guide posts are provided at four positions on one side surface of the buffer ring, and the outer wall of the guide posts is slidably connected to the inside of the guide ring.

[0012] Preferably, a buffer spring is provided at the center of the buffer ring, and the buffer spring is slidably connected to the outer wall of the output shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This worm gear drive damper, through a dual buffer design of buffer spring and damper itself, can effectively absorb the excessive driving force generated when the worm gear drives a long worm, avoid deformation and wear of internal components of the damper, significantly extend the service life and operational stability of the damper, and meet the usage requirements of long worm gear drive scenarios.

[0014] The worm gear and damper adopt a detachable structure with a pin-socket fit and stud-nut fixation, which can be disassembled and assembled without special tools. This makes it convenient to operate when maintaining, repairing or replacing the worm gear, buffer spring and other parts. It avoids the overall scrapping problem caused by one-piece molding or tool-assisted installation structure, reduces the use cost and resource waste. At the same time, the double fixing structure ensures a stable connection during transmission and eliminates the risk of loosening. Attached Figure Description

Figures 1-4 The damper includes a damper 1, an output shaft 101 is installed at one end of the damper 1, a pin 102 is installed at one end of the output shaft 101, a threaded hole A103 is opened at the center of the pin 102, and a guide ring 2 is installed on one side of the outer wall of the damper 1. A worm gear transmission auxiliary assembly is installed on one side of the damper 1. The worm gear transmission auxiliary assembly includes a worm 3, a worm wheel 301 is installed on the top of the worm 3, and the teeth on the worm wheel 301 mesh with the teeth on the worm 3. A socket 302 is installed at one end of the worm 3. A threaded hole B303 is opened at the center of the socket 302. A stud 304 is installed inside the threaded hole B303. The outer wall of the stud 304 is threadedly connected to the inside of the threaded hole B303. A nut 305 is threadedly connected to the lower part of the outer wall of the stud 304. The nut 305 is located below the socket 302. A buffer ring 306 is installed at one end of the socket 302. The outer wall of the buffer ring 306 is slidably connected to the outer wall of the output shaft 101. Guide posts 307 are provided at four positions on one side surface of the buffer ring 306. The outer wall of the guide posts 307 is slidably connected to the inside of the guide ring 2. A buffer spring 308 is provided at the center of the buffer ring 306. The buffer spring 308 is slidably connected to the outer wall of the output shaft 101.

[0019] The damper 1 is the core damping component, made of high-strength metal material, and has a stable damping energy dissipation function. One end of it is fixedly installed with an output shaft 101 by a coupling or welding. The output shaft 101 is a cylindrical metal shaft used to transmit damping force and connect to the worm gear transmission assembly.

[0020] One end of the output shaft 101 is fixedly mounted with a pin 102 by bolts or welding. The pin 102 is a cylindrical metal block with an outer diameter that matches the inner diameter of the socket 302, used to achieve precise docking between the worm gear 3 and the output shaft 101. A threaded hole A103 is provided at the center of the pin 102 for fixing with a stud 304. A guide ring 2 is fixedly mounted with bolts on one side of the outer wall of the damper 1. The guide ring 2 is an annular metal part with four evenly distributed guide holes inside, used to slide with the guide post 307 to ensure smooth movement of the buffer ring 306.

[0021] A worm gear transmission auxiliary component is installed on one side of the damper 1. The core component is the worm 3, which is made of high-strength alloy material and has precision teeth on its surface. A worm wheel 301 is installed on top of it. The teeth on the worm wheel 301 mesh with the teeth on the worm 3, and the worm 3 is driven to move axially by rotating the worm wheel 301.

[0022] One end of the worm gear 3 is fixedly mounted with a socket 302 by welding. The socket 302 is a cylindrical metal sleeve with a hollow interior, which can be fitted with the pin 102 for positioning. A threaded hole B303 is opened at the center of the socket 302. The threaded hole B303 has the same diameter and corresponding position as the threaded hole A103 of the pin 102, and is used to install the stud 304.

[0023] The stud 304 is a fully threaded metal screw. Its outer wall is connected to the internal thread of the threaded hole B303. One end of the stud can pass through the threaded hole B303 and be screwed into the threaded hole A103 to fix the worm gear 3 to the output shaft 101. A nut 305 is threadedly connected to the lower part of the outer wall of the stud 304. The nut 305 is a metal nut with anti-slip texture, located below the socket 302. Tightening it can further lock the stud 304 and prevent loosening.

[0024] A buffer ring 306 is fixedly installed at one end of the socket 302 by bolts or snap-fit. The buffer ring 306 is a ring-shaped metal part, and its inner wall is slidably connected to the outer wall of the output shaft 101 with a clearance, allowing it to move axially along the output shaft 101. Guide posts 307 are evenly arranged at four positions on one side surface of the buffer ring 306. The guide posts 307 are cylindrical metal rods, and their outer walls are slidably connected to the guide holes of the guide ring 2 to ensure that the buffer ring 306 does not deviate when moving.

[0025] A buffer spring 308 is provided at the center of the buffer ring 306. The buffer spring 308 is a highly elastic compression spring that is slidably connected to the outer wall of the output shaft 101. One end is in contact with one side surface of the buffer ring 306, and the other end is in contact with the end face of the damper 1 or the stepped surface of the output shaft 101, so as to provide elastic buffering force for the buffer ring 306.

[0026] Working principle: When using this utility model, the damper is first assembled: the buffer spring 308 is fitted onto the free end of the output shaft 101, with one end fitting against the end face of the damper 1 or the preset stepped surface of the output shaft 101, ensuring the spring is in a naturally extended state. The buffer ring 306 is then fitted onto the output shaft 101, with one side surface of the buffer ring 306 fitting against the other end of the buffer spring 308. Simultaneously, the four sets of guide posts 307 on the surface of the buffer ring 306 are aligned with the four guide holes of the guide ring 2 and inserted, ensuring that the buffer ring 306 can slide smoothly along the output shaft 101 and the guide posts 307.

[0027] Align the socket 302 at one end of the worm gear 3 with the pin 102 of the output shaft 101, and slowly insert it until the end face of the socket 302 is in contact with the other side surface of the buffer ring 306. At this point, the threaded hole B303 of the socket 302 is precisely aligned with the threaded hole A103 of the pin 102. Screw the stud 304 into the threaded hole B303 from the outside of the socket 302, and continue screwing it into the threaded hole A103 of the pin 102 until the stud 304 is tightened, thus achieving initial fixation between the worm gear 3 and the output shaft 101. Then screw the nut 305 into the lower outer wall of the stud 304 and tighten it until it fits tightly against the bottom of the socket 302, completing the double fixation and ensuring a stable connection during transmission.

[0028] When the damper is working, external power drives the worm gear 301 to rotate. The worm gear 301 drives the worm 3 to move axially through tooth meshing. The worm 3 drives the output shaft 101 to move synchronously through the socket 302 and the pin 102. The damper 1 exerts its own damping effect, consuming kinetic energy to achieve the damping effect. When the driving force of the worm gear 301 driving the worm 3 is too large, the worm 3 squeezes the buffer ring 306 through the socket 302. The buffer ring 306 slides along the output shaft 101 and the guide post 307 towards the damper 1, squeezing the buffer spring 308. The buffer spring 308 undergoes elastic deformation, generating a reverse elastic force, absorbing the excessive driving force, forming a double buffer with the damping effect of the damper 1, effectively weakening the impact force and preventing damage to the internal components of the damper 1 due to excessive force.

[0029] When maintenance, repair, or replacement of parts is required later, disassemble according to the following steps: First, loosen and remove nut 305 counterclockwise. Then, unscrew stud 304 counterclockwise until it is completely disengaged from threaded holes A103 and B303. Hold the worm gear 3 and pull it away from damper 1 to disengage socket 302 from pin 102, completing the disassembly of worm gear 3. Next, pull buffer ring 306 outward along output shaft 101 to disengage guide post 307 from guide ring 2. Finally, remove buffer ring 306 and buffer spring 308 to inspect, repair, or replace each component. After replacement, reverse the assembly steps to restore the device to use. No special tools are required throughout the process, making it convenient and efficient.
