Minimum flow of the feed pump must be adapted to suit operating conditions. Open circuit Minimum inlet pressure must be adapted to suit operating conditions; the following must be taken into consideration: idling pressure, flow resistances, pump operation. The outlet pressure must be at least bar greater than the pressure in the housing. If the motor circuits are in series please consult the manufacturer.

2 /8 osch Rexroth G Mobile Hydraulics MCR 15 RE 15 08/10.94 Section, Function Hydraulic motors Type MCR are radial piston motors with a rotating shaft. Construction Two-part housing (1; ), rotary piston assembly (3; 4) cam (5), output shaft () and control section (7) Transmission The rotor (4) is connected to the shaft () by means of splines.the pistons (3) are arranged radially in the rotor (4) and are supported on the cam plate (5) by way of rollers (8). Torque generation Feed Working stroke Idle stroke The number of working and idle strokes corresponds to the number of cams on the stroke curve. Open loop control The cylinder chambers (E) are connected to ports or by means of the axial bores and the annular passages (D). earings Tapered roller bearings capable of transmitting high axial and radial forces. Freewheeling If the two ports and are connected with no pressure loading and a pressure of bar is simultaneously applied to the housing by way of port, the pistons will be forced into the rotary piston assembly. The rollers will no longer be lying against the cam curve and it will be possible for the end of the shaft to be rotated. Switching to half displacement On certain models of radial piston motors halving of displacement is possible. This means that at working stroke only half the pistons are supplied with fluid by way of a valve in the control system. The remaining pistons are connected to the outlet side of the motor. When connected the motor will run at twice the speed but at half torque. D D 7 D 7 Return Mounting the brakes Holding brake (multi-disc brake) 11 Wheel brake (drum brake) Mounting: y way of control housing () and through drive. rake application If the pressure in the annular area (9) falls short of a pre-determined level, the elleville washer (10) will press the disc package (11) together. rake release If the pressure in the annular area (9) exceeds the required level, the brake piston (1) will be pushed against the elleville washer (10). The load is taken off the disc package (11), and the holding brake released. Mounting Directly onto output shaft () and flange housing (1). Operating the brake hydraulic for dynamic braking mechanical as a holding brake
