DANA Orbital Motor

HYDRAULIC MOTORS

Operating principle

Hydraulic motors convert hydraulic energy (pressure, oil flow) into mechanical energy (torque, revolutions). In the case of orbital motors, this conversion is made by the drive component (orbital unit): an external stator with internal toothing and a rotor (with planetary motion) of suitable profile. Our orbital motors have fixed displacement.

GEARWHEEL SET

There are two types of gearing: the BGM, BG, and BH have gears with matching profiles (Gerotor gear set: fig. 1 a-b), whereas the BR, BS, ARS, ARF, HR and HT have rollers between the two gears (Geroller gear set: fig. 1 c-d-e).
