The harden face gear units include both Z and D series and can be used in metallurgy, mining, transportation, cement, architecture, chemical industry, textile, light industry and energy industry ,etc. They have many features as following:
Ambient Conditions
| Gear | Gear is manufactured by high-quality alloy steel with carburizing and quenching. The tooth surface hardness is HRC57-61. |
| Gear Root | Strength the gear root by shot peening to improve the bending strength in gear root. |
| Casing | Use the split casing to facilitate repairs |
| Transmission Efficiency | 98% for the single-stage, 96% for the double-stage, 94% for the three-stage and 92% for the four-stage. |
Ambient Conditions
| Speed of high-speed shaft | The input speed of high-speed shaft is equal or less than 1500r/min |
| Circular Velocity of gear | equal or less than 20m/s |
| Ambient Temperature | The ambient temperature ranging from -40 to 50 ºC. When lower than 0 ºC, please heat the lubricant before the operation |
