      Method of reducing gear transmission noise

      Method of reducing gear transmission noise

       1. Control the accuracy of the gear. If the gear accuracy is accurate, it means that there will be no joint wear between components during transmission, and the possibility of noise can also be reduced.

       2. Control the quality of raw materials. Either way, raw materials must undergo strict chemical composition inspection, particle size determination and purity evaluation after reaching the factory. The purpose is to adjust the heat treatment deformation in time and improve the tooth profile processing quality.

       3. Prevent heat treatment deformation. After rough machining, the gear blank is refined forging, normalized or quenched and tempered to: (1) soften the steel for cutting; (2) Refine grain size, improve microstructure and improve mechanical properties of steel; (3) Be prepared for the treatment.

       4. Ensure the accuracy of tooth blank. The accuracy of gear hole size is required to be distributed in the middle of the hole deviation value. If it exceeds the tolerance and is within the design requirements of the hole, it will be classified and transferred to the tooth cutting process.
