Simplifying the clamping system between motor shaft and gear, reducing the output torque to a level standard on the market and reducing gear ratios has enabled B&R to offer a cost-optimized gearbox. This series is available with gear ratios of 5,10 and 25. The output shaft is only available with a keyway.
Planetary gearboxes with output shaft 8GP
The standard gearboxes are single-stage for gear ratios i= 3, 4, 5, 7, 8 and 10 and have ≤8 - ≤15 arcmin backlash. In addition, these gearboxes are also offered in two-stage or three-stage designs. At the top of the product line, the premium series provides backlash ≤ 1 arcmin as an option paired with high output torques. B&R gearboxes from the standard series give you the possibility to choose between all output geometries established on the market in the area of coaxial planetary gearboxes.
- This enables B&R to supply gearboxes for existing applications without having to make changes to the machine.
With the 8GP55 series, you are also able to combine the output bearings and the output geometry of the 8GP60 premium series in combination with the torsional play of the standard series for applications that do not require extremely reduced backlash. This makes it possible to handle high radial and axial forces in a cost-efficient manner.
- In applications where the backlash of the standard series is sufficient, this offers a cost-optimized solution for implementing higher bearing forces.
