The suitable scope of speed reducer is as follows:

1. The rotation of high speed shaft should not be more than 1500 rpm
2. The circumferential velocity of gear tranmission should not be more than 20 m/sec;
3. The temperature of work environment should be -40-45°C. If it below 0°C, before start, the lubricating oil should be pre-heated to above 0°C. This speed reducer can be run at clockwise and counterclockwise direction.

Characteristics:

1. The gear is made of high strength low carbon alloy steel through carburization and quenching. The hardness of tooth surface may reach to HRC58-62. All gear adapts NC tooth grinding process, high in accuracy and good in contact performance:
2. Highly tranmission efficiency: single stage, more than 96.5%; double-stage, more than 93%; Three-stage, more 90%;
3. Smooth and stable in run, low noise;
4. Compact, light, long life, high bearing capacity; Easy to disassemble, inspect and assemble.
