DISC VALVE HYDRAULIC MOTORS GENERAL INFORMATION: Orbit motors convert hydraulic energy (pressure, oil flow) into mechanical energy (torque, speed). Hydraulic orbit motors operate on the principle of an internal gear (rotor) rotating within a fixed external gear (stator). The internal gear transmits the torque generated by the application of pressure from hydraulic oil fed into motor which is then delivered via the motor's output shaft. Orbit motors have high starting torque and constant output torque at wide speed range. The output shaft runs on tapered roller bearings and can absorb high axial...

MLHS MOTORS DIMENSIONS AND MOUNTING DATA - MLHSBD (MOTOR WITH DRUM BRAKE) Actuating the brake level, the brake shaft is turned. The rectangular shape of the inner part of this shaft forces the brake pads to be pressed against the brake drum. This brakes the wheel or the winch drum. Releasing the level, the springs pull it and the brake pads back to the initial position. The motor output A B shaft is released. Minimum angle adjustment is 10º. It can be adjusted by dismantling the level. Depending on the application You can choose the actuating direction of the brake level. The rod connection actuating...
