GS planetary gearboxes are an evolutionary improvement of the GE series. They offer the same excellent value that distinguishes the GE series while providing greater torque density and compatible anchor points. Designed to work with servomotors in either continuous or intermittent operation, they are suitable for applications where extremely low backlash is not fundamental.
Performance data:
| Number of stages: | 1 and 2 stages |
| Transmission ratios: | 3 to 100 |
| Output torque: | Up to 269 Nm |
| Backlash: | <10' or <15' |
| Input motor flanges: | For servomotors and asynchronous motors |
| Output shaft | With key |
GS Planetary gear units have the following advantages:
- 40000 hour design life, twice the market standard
- Compact design due to torque division
- High power density (Nm / dm3)
- Low volume and weight
- Coaxial drive and output shafts
- Maximum operating safety
- High efficiency: 97% for one stage and 95% for a two stages gearbox
- Intermittent and continuous operation
- Maintenance free thanks to lifetime synthetic grease lubrication
- High quality at economical price
- ATEX standard requirements
- Optional H1 food grade lubrication for industries that require it
- Mounting in any position
- Very easy and precise motor installation thanks to clamping ring technology
- Low running noise thanks to high gearing quality
With 3 planet wheels per stage, GS Planetary gear units attain a very good load balancing, resulting in very high operating safety and very smooth running. The standard series includes 1, and 2 stage planetary gearboxes with ratios from 3 to 100. Higher gear reductions can be attained by adding additional stages.
Torques
The standard series has torques up to 269 Nm. However, SERVOTAK also has heavy-load precision gearboxes series that allow torques up to 9000 Nm (SG), 12000 Nm (SGM) and 16000 Nm (SGH).
Gears, planet carrier and housing
The ring gear, made of treated steel, is an integral part of the housing, sun and planet wheels are made of case-hardened steel, and both bearing flanges are made of aluminum. The single piece planet carrier and output shaft is made of ductile iron, resulting a robust design.
