Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, specifically a servo motor vibration damping and fixing mechanism. Background Technology

[0002] In industrial automation and numerous mechanical drive fields, servo motors serve as crucial power output and control components, and their operational stability and precision directly impact the performance of the entire system. During operation, servo motors not only generate their own vibrations but are also subject to vibration interference from external equipment and the environment. If these vibrations are not effectively controlled, they will trigger a series of problems, severely affecting the normal operation and lifespan of the equipment. Therefore, how to effectively fix servo motors and reduce the impact of vibration has always been a key research focus in this field.

[0003] Existing servo motor mounting technologies have several shortcomings in addressing vibration issues. Firstly, conventional mounting methods often focus solely on simply fixing the servo motor to the equipment frame, lacking specialized vibration damping design. The mounting base is typically a rigid structure, unable to effectively buffer and absorb vibrations from the ground or other equipment, causing vibrations to be directly transmitted to the servo motor, affecting its operational stability. Secondly, traditional methods fail to adequately balance vibration damping and stability when mounting the servo motor's output shaft. The bearing installation lacks effective vibration damping structures; during motor operation, even minor vibrations of the output shaft can easily cause bearing wear, affecting transmission accuracy. Furthermore, prolonged exposure to vibration can easily loosen and damage internal components of the servo motor, reducing its reliability and lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a servo motor vibration damping and fixing mechanism to solve the problem of poor vibration damping effect of existing servo motor fixing mechanisms mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A servo motor vibration damping and fixing mechanism includes a fixed base, on the top surface of which are mounted several sets of vibration damping brackets for fixing the servo motor and bearing brackets for fixing the output shaft of the servo motor. The bottom of the fixed base is equipped with a first shock-absorbing pad, the cross-section of the shock-absorbing bracket is inverted U-shape, the bottom sides of the shock-absorbing bracket are symmetrically provided with fixed feet, the center of the top surface of the shock-absorbing bracket is equipped with a positioning threaded post and a matching positioning nut, and the top surface of the shock-absorbing bracket is provided with a second shock-absorbing pad. The bearing is mounted on the top of the bearing bracket, and a shock-absorbing ring seat is fitted on the outer ring wall of the bearing.

[0006] Preferably, mounting holes are provided at the four corners of the fixed base and the first shock-absorbing pad, which can quickly and accurately position and fix them, improving installation efficiency and ensuring the stability of the installation, thus laying the foundation for the stable operation of the servo motor.

[0007] Preferably, the fixing feet are installed on the top surface of the fixed base by several sets of connecting bolts, which ensures the firmness of the connection between the shock-absorbing bracket and the fixed base, can effectively withstand the various forces generated by the servo motor during operation, and is easy to disassemble and maintain, making it more convenient when it is necessary to adjust or replace parts.

[0008] Preferably, the bottom of the shock-absorbing bracket is equipped with shock-absorbing blocks that are adapted to the internal cross-sectional dimensions, further enhancing the shock absorption effect. The shock-absorbing blocks can better absorb and disperse the vibration energy transmitted from the servo motor, reducing the impact of vibration on the fixed base and other connected equipment, and improving the stability of the entire system.

[0009] Preferably, reinforcing ribs are provided between the top surface of the bearing bracket and the fixed base, which significantly enhances the strength and stability of the bearing bracket. This better supports the servo motor output shaft and related components, withstands greater loads, prevents deformation of the bearing bracket during long-term use, and ensures the normal operation of the servo motor output shaft.

[0010] Preferably, the bearing has several sets of locking bolts installed on the outer wall of the inner ring for locking the output shaft of the servo motor. This ensures a tight connection between the output shaft of the servo motor and the bearing, prevents axial or radial displacement of the output shaft during operation, improves the accuracy and reliability of the transmission, and guarantees the control precision of the servo motor.

[0011] Preferably, the outer wall of the shock-absorbing ring seat is equipped with positioning bolts for connection to the outer ring wall of the bearing, so that the shock-absorbing ring seat can be firmly fixed to the bearing. In this way, when the servo motor is running, the shock-absorbing ring seat can better perform its shock absorption function, reduce the vibration of the outer ring of the bearing, protect the bearing, extend its service life, and also help maintain the stable operation of the servo motor output shaft.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: In this servo motor vibration damping and fixing mechanism, the fixed base and the first damping pad at its bottom provide a stable foundation for the entire mechanism and effectively reduce the transmission of vibrations from the ground. The cross-section of the damping bracket is inverted U-shaped, and the fixed feet symmetrically arranged on both sides of its bottom ensure the stability of the bracket. The positioning threaded post and matching positioning nut installed at the center of the top surface of the damping bracket facilitate the fixed installation of the servo motor. At the same time, the second damping pad on the top surface of the damping bracket further reduces the vibration generated during motor operation. The bearing installed on the top of the bearing bracket and the damping ring seat fitted on the outer ring wall of the bearing effectively support the output shaft of the servo motor and reduce its vibration during operation, thereby improving the stability and damping effect of the entire mechanism. The bearing cover and the bearing work together to ensure the stable operation of the servo motor output shaft. Attached Figure Description

[0017] Servo motor vibration damping and fixing mechanism, such as Figs. 1-3 As shown, the system includes a fixed base 10, on the top surface of which are mounted several sets of shock-absorbing brackets 20 for fixing the servo motor and bearing brackets 30 for fixing the output shaft of the servo motor.

Fixed feet 21 are symmetrically arranged on both sides of the bottom of the shock-absorbing bracket 20. A positioning threaded post 23 and a matching positioning nut 25 are installed at the center of the top surface of the shock-absorbing bracket 20. A second shock-absorbing pad 24 is provided on the top surface of the shock-absorbing bracket 20. A bearing 32 is mounted on the top of the bearing bracket 30. A shock-absorbing ring seat 31 is fitted on the outer ring wall of the bearing 32. Through the fixed base 10 and the first shock-absorbing pad 11 at its bottom, a stable foundation is provided for the entire mechanism and the vibration transmission from the ground is effectively reduced. The shock-absorbing bracket 20 has an inverted U-shaped cross-section. Symmetrically arranged fixing feet 21 on both sides of its bottom ensure the bracket's stability. The positioning threaded post 23 and matching positioning nut 25 installed at the center of the top surface of the shock-absorbing bracket 20 facilitate the fixed installation of the servo motor. Simultaneously, the second shock-absorbing pad 24 on the top surface of the shock-absorbing bracket 20 further reduces vibrations generated during motor operation. The bearing 32 installed on the top of the bearing bracket 30, and the shock-absorbing ring seat 31 fitted on the outer ring wall of the bearing 32, effectively support the servo motor output shaft and reduce its vibration during operation, thereby improving the stability and shock absorption effect of the entire mechanism. The bearing cover (labeled 35) works together with the bearing to ensure the stable operation of the servo motor output shaft.

[0018] Furthermore, mounting holes 12 are provided at the four corners of the fixed base 10 and the first shock-absorbing pad 11, so that the entire mechanism can be securely installed on other equipment or structures through these mounting holes 12, thereby enhancing the flexibility and stability of the installation.

[0019] It is worth noting that the fixing feet 21 are installed on the top surface of the fixed base 10 by several sets of connecting bolts 22, so that the shock-absorbing bracket 20 can be firmly fixed on the fixed base 10, while facilitating disassembly and maintenance, thus improving the practicality and reliability of the structure.

[0020] The shock-absorbing bracket 20 has a shock-absorbing block 26 at its bottom that matches the internal cross-sectional dimensions, which further enhances the shock absorption effect of the shock-absorbing bracket 20, effectively absorbs and disperses the vibration generated during the operation of the servo motor, and protects the motor and other equipment from vibration.

[0021] Specifically, a reinforcing rib 33 is provided between the top surface of the bearing bracket 30 and the fixed base 10.

[0023] Working principle of this servo motor vibration damping and fixing mechanism: First, the entire mechanism is securely installed in the predetermined position using the mounting holes 12 at the four corners of the fixed base 10 and the first damping pad 11. Next, the damping bracket 20 is firmly fixed to the top surface of the fixed base 10 using its bottom fixing feet 21 and connecting bolts 22. The damping blocks 26 at the bottom of the damping bracket 20 effectively enhance the damping effect. Then, the servo motor is placed on the damping bracket 20 and fixed using the positioning threaded post 23 and positioning nut 25. Simultaneously, the second damping pad 24 on the top surface of the damping bracket 20 reduces motor vibration.

[0024] Next, the bearing bracket 30 is installed onto the fixed base 10, and the reinforcing rib 33 between it and the base ensures the stability of the support. The bearing 32 is installed on top of the bearing bracket 30, and the shock-absorbing ring seat 31 is fixed to the outer ring wall of the bearing 32 by the positioning bolt 35. Then, the output shaft of the servo motor is passed through the bearing 32 and the output shaft is locked by the locking bolt 34.
