What is the reason for the loud noise when using a gearbox? In fact, there are several reasons why the gearbox produces loud noise during operation:
The first reason is that the gears of the reducer are damaged or worn out, causing a lot of wear and oscillation between the gears, which leads to a lot of noise during the operation of the reducer. This greatly affects the normal operation of the reducer, resulting in a lot of noise.
The second reason is that the device position of the reducer is not stable, or the ground where the reducer is located is uneven, which causes the reducer to always be in a shaking state during operation, and then presents noise and other phenomena.
The third reason is that there is a mechanical malfunction inside the gearbox. It should be noted that damage or shortage of internal parts of the gearbox can cause it to produce significant noise and even reduce its service life.
The fourth reason is the improper use of the gearbox. The gearbox is a precision instrument that requires professional technicians to operate. If operated improperly, excessive load or speed of the gearbox will produce great noise.
Do you know how to solve the above situation? Let me tell you about the solution to noise!
The noise generated by reducers mainly comes from the friction, vibration, and collision of transmission gears. How to effectively reduce and minimize noise to make it more in line with environmental requirements is also a key research topic at home and abroad. Reducing the gear transmission noise during the operation of reducers has become an important research topic in the industry. Many scholars at home and abroad consider the changes in tooth mesh stiffness in gear transmission as the main factors of gear dynamic load, vibration, and noise. By using shape modification methods, the dynamic load and velocity fluctuations are minimized to achieve the goal of reducing noise. This method has been proven to be a more effective approach in practice. However, using this method requires shaping equipment in the process, which is often not feasible for large, medium, and small factories in Guangzhou.
After years of research, a gear design method has been proposed to reduce or avoid gear pitch circle impact by optimizing gear parameters such as displacement coefficient, tooth height coefficient, pressure angle, and center distance, so as to minimize the meshing impact velocity and keep the ratio of meshing impact velocity to meshing impact velocity within a certain numerical range. This method can also significantly reduce gear noise in reducers. For the noise problem of the gearbox, Maitre super sealant or lubricant can also be used. It is an excellent gearbox additive that can form an inert material film on the components, thereby reducing friction, gear noise, and leakage.
