  • 1. Gear assembly used in drive unit of locomotive

    We manufacture the gear assembly for freight locomotive and passenger locomotive. Our products have already passed SIEMENS and Alston system authentication, and their capabilities are as excellent as the import unit.

     
  • 2. High speed and accurate gear transmission

    We had done many study works on the thermal deformation, calculating of elastic distortion and tooth flank modification of high-speed gear. We successfully developed various types of high accuracy gear products with pitch line velocity over 180m/s, maximum rotational speed 60000r/min, and tooth surface load factor over 200N/cm2.
