B. Advantages
1. Modular design, has many ratios, motor combinations, mounting positions and structures to meet the different working conditions.
2. Gears are made of high quality alloy steel, the surface hardness can be HRC58-62 after heat treatment (such as carburizing and quenching), the precision is 5-6 grades.
3. Using computer gear tooth modification technology to improve load capacity of reducer.
4. Design and manufacture by CAD/CAM technology to assure stability of quality.
5. Has high transmission precision, adapts to frequent start occasions.
6. Good sealing performance, strong suitability for the working conditions.
7. The gearbox surface is uneven, so has larger surface area and cooling effect, also has strong vibration absorption, low noise and long lifetime.
8. Output very low rotary speed
9. High strength, compact: The box body is made of high strength cast iron
10. Gear and gear shaft adapts the gas carbonization, quenching and fine grinding process, therefore the bearing capacity of unit volume is high
11. Low noise, High efficiency, Long lifespan
