Keywords:

Single stage gear ratio can reach 6,max to 8 or above,transmission efficiency normally is 0.94~0.98.

  1. It’s easy to design,produce,install spur gear and bevel gear,but high noise,used for low speed transmission(<5m/s);spur gear and bevel gear’s transmission power can reach 370kw,peripheral speed 5m/s.bevel gear transmission is stable,big loading ability,but difficult to produce,less application.
  2. Curved teeth bevel gear has features of transmit stable,low noise,big loading capacity,used for high speed,heavy loading condition.transmission power can reach 3700kg,peripheral speed above 40m/s.contains spur bevel gear and spiral bevel gear.

Advantage:

  1. High-precision dimensional tolerance;
  2. Excellent mechanical properties;
  3. Produce different dimension based on customer’s requirements;
  4. Advanced manufacture equipments and inspection devices;
  5. Excellent technical personality;
  6. Control the production procedure strictly;
  7. Pay attention on the package protection;
  8. Quality full service.
