Servo drive technology
7.1 Servo gear units
Helical-bevel servo gear units
BS.F series
Features
–
Low-backlash helical-bevel servo gear units
–
Designed for torque classes from 40 Nm to 1 220 Nm
–
Five output variants:
- BSF: Solid shaft
- BSKF: Solid shaft with key
- BSBF: Flange block shaft (EN ISO 9409)
- BSHF: Hollow shaft with shrink disk
- BSAF: Hollow shaft with key (shaft-mounted gear unit)
–
All variants with B5 mounting flange; foot-mounting and torque arm are optional (
i
can be
optimally integrated into the relevant application)
–
The rotational clearance remains constantly low over the entire gear unit service life
