Gear transmission noise reduction method
Jun 14, 2018

In order to avoid that the reducer can not pass the factory test, one of the reasons is that the reducer has intermittent high noise; with the ND6 precision sound level meter test, the low noise reducer is 72.3Db(A), which meets the factory requirements; and the high noise is reduced The machine is 82.5dB(A), which does not meet the factory requirements. After repeated testing, analysis and improvement of the test, the conclusion is that it is necessary to carry out comprehensive treatment of all aspects of production in order to effectively reduce the noise of the gear transmission.


1. Accuracy of Control Gears: Basic Requirements for Gear Accuracy: After practice, the accuracy of gears must be controlled in GB10995-887~8, the line speed is higher than 20m/s, the pitch deviation limit, the radial runout tolerance of the gear ring, Tooth tolerances must be stable to achieve level 7 accuracy. In the case of a 7-degree precision gear, the teeth must be chamfered and root projections must be prevented.


2. Controlling the quality of raw materials: High-quality raw materials are prerequisites for the production of high-quality products. The company's most used materials, 40Cr and 45 steel, make gears. Regardless of the method used, raw materials go through the strict chemical composition test, grain size measurement, and purity evaluation after they arrive at the factory. Its purpose is to timely adjust the heat treatment deformation and improve the quality of the tooth profile machining
