Reducer Noise Reduction Treatment
The noise generated by reducers mainly originates from friction, vibration, and collision of the transmission gears. How to effectively reduce and minimize noise to meet environmental requirements has become a key research topic both domestically and internationally.
Reducing gear transmission noise during reducer operation has become an important research subject in the industry. Many scholars at home and abroad consider the variation in tooth meshing stiffness during gear transmission as the main factor causing dynamic loads, vibration, and noise. Using profile modification methods to minimize dynamic loads and speed fluctuations has proven to be an effective approach for noise reduction in practice. However, this method requires profile modification equipment in the process, which many small and medium-sized enterprises often cannot implement.
After years of research, a gear design method has been proposed that can significantly reduce reducer gear noise by optimizing gear parameters such as modification coefficient, tooth height coefficient, pressure angle, and center distance. This approach minimizes the meshing impact velocity and maintains the ratio between meshing-out impact velocity and meshing-in impact velocity within a certain range, thereby reducing or avoiding meshing pitch circle impact.
For the noise issue of reducers, Lashing super sealant or lubricant can also be used. It is an excellent gearbox additive that can form an inert material film on components, thereby reducing friction, gear noise, and leakage.
Precautions for Reducer Break-in Period
After leaving the factory, reducers generally have a specified break-in period of about 200 hours (oil must be changed after this time), which is stipulated based on the technical characteristics during the initial use of the reducer. The break-in period is a crucial stage to ensure normal operation, reduce failure rates, and extend the service life of the reducer. Technical personnel from Lashing have provided the following precautions:
1. Properly select lubricating oil, especially for reducer motors with input power greater than 11KW, which must use medium-load gear oil. Pay attention to regularly checking the lubricating oil, hydraulic oil, coolant, oil level and quality, and check the sealing of the entire machine. If oil shortage or excess is found during inspection, the cause should be analyzed. At the same time, lubrication of all lubrication points should be strengthened. It is recommended to add grease to lubrication points weekly during the break-in period (except for special requirements). For vertical reducers with oil pumps, when the pump is powered on before the main power supply, pay attention to the pump’s rotation direction. Clockwise rotation is correct.
2. Keep the reducer motor clean, promptly adjust and tighten loose components to prevent increased wear or loss of components due to looseness.
3. At the end of the break-in period, the machine should undergo mandatory maintenance, with inspection and adjustment work carried out, while also paying attention to oil replacement.
In summary, the requirements for the use and maintenance of reducers during the break-in period can be summarized as: strengthen training, reduce load, pay attention to inspection, and enhance lubrication. As long as attention is paid to and the maintenance and care of the reducer during the break-in period are implemented as required, early failures will be reduced, service life will be extended, production efficiency will be improved, and the reducer will bring you more benefits.
