What are the methods to reduce noise of cycloidal reducer?

Reducing the gear transmission noise during the operation of the cycloidal reducer is an important research topic in the industry.Many people at home and abroad regard the change of gear mesh stiffness in gear transmission as the main factor of gear dynamic load, vibration and noise.

By repairing the shape, dynamic loads and velocity fluctuations can be reduced to a very small level, thereby reducing noise.This is a more efficient approach.It is difficult for manufacturers to repair equipment technologically.

When installing couplings, pulleys, sprockets and other couplings on the output shaft of the cycloidal reducer, the direct hammering method cannot be used because the output shaft structure of the cycloid reducer cannot withstand axial hammering. This can be changed to a shaft end tapped hole, a screw in, and a press-in coupling.Through long-term investigation, a gear design method is proposed to reduce the meshing impact speed by optimizing gear parameters, such as displacement coefficient, tooth height coefficient, pressure angle and center distance, and reduce the ratio of meshing impact speed to a certain value. Within the range, it can reduce or prevent meshing pitch circle impact and also effectively reduce gear noise.

Due to long-term high-torque mechanical movement in the gearbox, bearing box, thread seal, mechanical seal and other parts of the cycloidal reducer, the meshing gap of the gearbox becomes larger, causing greater noise and equipment vibration.In addition, the sealing part operates at high speed and high temperature for a long time, and oil leakage from the sealing part often occurs.Due to serious oil leakage during equipment operation, it brings many disadvantages to reliable production. The traditional method requires a long shutdown to disassemble and replace the sealing gasket and process the joint surface. It is impossible to achieve effective control during equipment operation. The traditional method is impossible.

In the 21st century, this problem can be solved by adding new lubricants. Among many materials, Maitre sealants & lubricants have better application effects, which have strong self-lubricating properties and reduce the gaps in the meshing parts. Effectively alleviate equipment noise and oil leakage problems at dynamic sealing parts.Lubricant is a kind of oil additive that will not cause pollution or deterioration of oil. It can solve hidden dangers in production without shutting down the company, and save companies high maintenance or replacement costs.
