Why does the reducer make noise? What are the main causes?
What are the reasons for the loud noise of the reducer?
1. Bearing: damaged or the gap is large or small.
2. Gear: low accuracy or damaged.
3. Motor: brake failure or fan problem, etc.
Nowadays, good brands of reducers generally use imported bearings, gear grinding, and motor optimization.
What are the main causes of noise during the running-in period of the reducer? How can I eliminate it as quickly as possible?
1. The noise caused by the running-in of gears cannot be eliminated quickly. It will be fine after the running-in period.
2. Poor alignment will produce noise
3. Noise generated by equipment vibration transmitted to the reducer
4. Noise caused by vibration due to insufficient rigidity of the reducer installation base
5. Noise generated by resonance of the reducer
Once the cause is found, the solution will be much easier
What is the reason for the loud noise in the speed machine?
The loud noise in the reducer is caused by the friction, vibration and collision of the transmission gear. How to effectively reduce and reduce the noise to make it more in line with environmental protection requirements is also a key research topic at home and abroad.
Reducing gear transmission noise when the reducer is running has become an important research topic in the industry. Many domestic and foreign scholars regard the change in gear tooth meshing stiffness in gear transmission as the main factor in gear dynamic load, vibration and noise.
Use the method of modification to minimize the dynamic load and speed fluctuation to achieve the purpose of reducing noise. This method has proven to be a more effective method in practice. However, this method requires process modification equipment, which is often not possible for the majority of medium and small factories.
Before putting the reducer into operation, install the recommended type and value of grease into the reducer. The reducer is lubricated with lubricating oil. For vertically installed reducers, additional lubrication measures are required since the lubricating oil may not guarantee reliable lubrication of the uppermost bearing.
Before operation, inject an appropriate amount of lubricating oil into the reducer. Reducers are usually equipped with oil filling holes and oil drain plugs. Therefore, the installation location must be specified when ordering the reducer.
The working oil temperature cannot exceed 80°C. Combination gearboxes lubricated for life are filled with synthetic oil at the manufacturer. In addition, the gearbox is usually supplied without lubricant and equipped with an oil filling plug and an oil drain plug.
The reducer lubricant quantities listed in this catalog are only estimates. Set the position of the oil level plug according to the installation position specified when ordering to ensure correct oil filling. The oil filling amount of the reducer should be determined according to different installation methods. If the transmitted power exceeds the thermal capacity of the gear unit, an external cooling device must be provided.
