Fast Response Infinite Variable Speeds Smooth Output Operation High Torque Performance Instant Reversibility

Instant Reversibility M Low Speed Operation Hartmann m i Unique Motor. UNIQUE ROL-VANE MOTOR PRINCIPLE. Key to the Hartmann Rol-Vane Motor's high torque - low speed operation and instant reversibility is the Rol-Vane principle. The motor's dual-vane rotor and timed interval valving create a hydraulically balanced unit, eliminating radial bearing loads - a major cause of hydraulic motor wear. SPLIT BODY DRIVE SHAFT TIMING GEARS Hydraulic fluid from the supply line flows to the rotor shaft via a com- bined body and shaft groove. Passages within the rotor shaft direct the pressurized fluid (...

HYDRAULIC MOTOR (100 psi across ports driving motor inertia only) OPERATING CHARACTERISTICS THE ROL-VANE HYDRAULIC MOTOR is an efficient and compact means of applying variable speed rotary hydraulic power. LINEAR OUTPUT TORQUE with constant input pressure. The pulseless torque is created by having a constant area operated on by a constant pressure at a constant radius. SYMMETRICAL REVERSIBILITY is obtained by having identical flow paths within the motor. SELF-LUBRICATION provided by the driving fluid. BALANCED PRESSURE AREAS and the elimination of mechanical rubbing surfaces minimizes...
