The low backlash BSF helical-bevel servo gear units are designed for the 40 to 1500 Nm (350 to 13200 lb-in) torque classes. The permitted acceleration torques are significantly higher than these values. These right-angle servo gear units are available in five output versions: BSF: Solid shaft BSKF: Solid shaft with key BSBF: Flange block shaft (EN-ISO 9409) BSHF: Hollow shaft with shrink disc BSAF: Hollow shaft with keyway (Shaft mounted gear unit) 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 bevel (wheel) and hypoid gear unit 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.
