2 RE 5 05/ /09.97 Section, Functional Description Feed 5 D Hydraulic motors type MCR are radial piston motors with a rotating shaft. Construction Two part housing (: ), rotor-piston assembly (: 4), cam (5), output shaft () and control section (7). Transmission The rotor (4) is connected to the shaft () by means of splines. The pistons () are arranged radially in the rotor (4) and are supported on the cam plate (5) by way of rollers (8). Torque generation Return Working stroke Idle stroke The number of working and idle strokes corresponds to the number of lobes on the cam. Open loop control The cylinder chambers (E) are connected to ports and via the axial bores and the annular passages (D). earings Tapered roller bearings are capable of absorbing high axial and radial forces. Freewheeling If the two ports and are connected with no pressure loading and a pressure of bar 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 freely. Switching to half displacement On certain models of radial piston motors halving of displacement is possible.this means that during the 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. In the switched position please take into account the preferred direction of rotation! D 7 E rake mounting Holding brake (multi-disc brake) 9 Mounting: by way of control housing () and through-drive facility. rake application If the pressure in the annular area (9) fails to reach a certain pressure the elleville washer (0) will compress the disc package (). Release of holding brake If the pressure in the annular 0 area (9) exceeds the required level, the brake piston () is pushed against the elleville washer. The load is taken off the multi-disc package () and the holding brake is released. Dynamic brake (drum brake) The brake may also be released manually by removing plug () and inserting a screw with a supporting washer into the hole in the piston (). Mounting directly on drive shaft () and flange housing (). Operation of brake hydraulic mechanical /
