The structure of a planetary speed reducer can be designed for repeated connection according to the required number of stages & realizes the multiple staged combination alone. Its small volume, light weight & compact outline.
The unique characteristic of uniform engagement of the planetary gear combination & arc enveloping structure of the external gear ring help with the robust engagement between the external gear ring & planetary gear. Apart from improving the extremely high speed reducer efficiency, the equipment itself can be selected to meet the requirements of positioning in high precision.
Efficiency
| Stage | Reduction Ratio | Efficiency |
L1 | 3.48 ~ 7.2 | 97% |
| L2 | 12.1 ~ 51.8 | 95% |
| L3 | 63 ~ 373 | 92% |
| L4 | 403 ~ 2687 | 90% |
Maintenance of the Planetary Gear Unit
Seal rings, anti-friction bearings and oil have only limited lifetime.
We recommend about 10 000 operating hours for the oil as well as the bearing greases should be changed.
As the lubricant ages in gear standstill it may become hard, a change of the lubricant, not depending on the actual operationg time, should be made at the latest after 3 years.
