Hydraulic motors type MCR are radial piston motors with arotating shaft.

ConstructionConstructionConstructionConstructionConstructionTwo part housing (1; 2), rotor piston assembly (3; 4) cam (5),output shaft (6) and control (7)

TransmissionTransmissionTransmissionTransmissionTransmissionThe rotor (4) is connected to the shaft (6) by means of splines.The pistons (3) are arranged radially in the rotor (4) and aresupported on the cam plate (5) by means of rollers.

Torque generationTorque generationTorque generationTorque generationTorque generation

The number of working and return strokes per pistoncorresponds to the number of lobes on the cam.

ControlControlControlControlControlThe cylinder chambers (E) are connected to ports A and B viathe axial bores and the annular passages (D).

BearingsBearingsBearingsBearingsBearingsTapered roller bearings are capable of absorbing high axial andradial forces.

FreewheelingFreewheelingFreewheelingFreewheelingFreewheelingIf the two ports A and B are connected with no pressureloading and a pressure of 2 bar is simultaneously applied tothe housing by way of port "L", the pistons will be forced intothe rotary piston assembly. The rollers will no longer be lyingagainst the cam curve and it will be possible for the end of theshaft to be rotated freely.

Switching to half displacement volumeSwitching to half displacement volumeSwitching to half displacement volumeSwitching to half displacement volumeSwitching to half displacement volumeOn certain radial piston motor models the displacement volumecan be halved. This happens when, at working stroke, onlyalternate pistons are supplied with hydraulic fluid via a valvein the control. The remaining pistons are connected to thedischarge side of the motor. The motor operates at doublespeed but half torque.

Mounting:Mounting:Mounting:Mounting:Mounting:by way of control housing(2) and through-drive facility.

Brake application:Brake application:Brake application:Brake application:Brake application:If the pressure in the annulararea (9) fails to reach a cer-tain pressure, the Bellevillewasher (10) will compressthe disc package (11).

Release of holding brake:Release of holding brake:Release of holding brake:Release of holding brake:Release of holding brake:If the pressure in the annulararea (9) exceeds the re-quired level, the brake piston(12) is pushed against theBelleville washer (10). Theload is taken off the multi-disc package (11) and theholding break released.
