Effective Measures to Reduce Gear Transmission Noise
2018-06-26 04:06:37

With the rapid development of the modernization of the machinery industry, in some areas, higher and higher requirements have been placed on the noise indicators of gear transmissions. After years of hard work, Hunan New Era have obtained some measures to effectively reduce gear transmission noise.

1. Guarantee the quality of raw materials

The commonly used materials for manufacturing gears are alloy steels such as 40Cr, 20CrMnTi, 40CrNi, and 45 steel. In order to ensure the quality of raw materials, we adopt a fixed-point purchase method. After going to the factory, we must undergo strict chemical composition testing. The purpose is to facilitate the heat treatment process, control of heat treatment deformation, improve the tooth Shape processing quality.

2. Prevent heat treatment deformation

After rough machining or precision forging, tooth blank must be normalized to eliminate internal residual stress. When in normalizing or quenching and tempering treatment, the uniformity of furnace temperature must be maintained. At the same time, using station fixtures to uniformly heat the workpiece and cool down

3. Improve the precision of gear blanks

①Improve the machining accuracy of the gear hole.

②Control the blank surface runout and radial runout.

4. Measures during cutting gear

① We test all gear cutters. ②Increasing tool life
