PSC series
|
|
The low backlash PSC planetary servo gear units are designed for torque classes from 30 to 320 Nm. They were designed to combine
the greatest possible flexibility and cost-efficiency because not every application requires high-performance components.
They provide a basis for diverse, dynamic and cost-optimized drive solutions.
The following types of PSC planetary servo gear units are available:

The low backlash PSF planetary servo gear units are designed for torque classes from 25 to 3000 Nm. The permitted acceleration
torques are significantly higher than these values.
Three output versions are available:

BSF series
|
|
The low backlash BSF helical-bevel servo gear units are designed for torque classes from 40 to 1500 Nm. The permitted acceleration
torques are significantly higher than these values.
These right-angle servo gear units are available in five output versions:
All versions are equipped with a B5 mounting flange and optional foot mounting and torque arm. Because of this, these drive
units can be optimally integrated into existing applications. The combination of a helical input stage and a hypoid output
stage results in ratio ranges which can be covered by the single-stage helical-bevel and hypoid gear units or by the single-stage
helical-worm gear unit with high transmission quality. The circumferential backlash remains constantly low throughout the
gear unit’s service life.
