4 + (0) MR, MRE Functional description Functional description E D F () A B C Hydraulic motors of the types MR and MRE are externally pressurized radial piston motors with fixed displacement. Design he main components are the housing (), the eccentric shaft (), the cover (), the control case (), the roller bearing (), the cylinder (6), the pistons (7) and the control unit (8.; 8.; 8.). Operating fluid inlet and return he operating fluid is fed into and from the motor via ports A or B. he cylinder chambers (E) are filled and emptied via the control unit and the ducts (D) in the housing (). Rotary group, torque generation Cylinders and pistons are supported on spherical surfaces on the eccentric shaft and on the cover. his allows the pistons and cylinders to align themselves as the shaft rotates without cross forces. ogether with a hydrostatic relief for the pistons and cylinders, this causes minimum friction and very high efficiency. he pressure in the cylinder chambers (E) acts directly on the eccentric shaft. Of the cylinders, or are connected to the inlet side or respectively to the outlet side. Control unit he control unit comprises the control plate (8.) and the distribution valve (8.). While the control plate is rigidly connected to the housing via pins, the distribution valve rotates at the same speed as the eccentric shaft. Boreholes in the distribution valve are the connection to the control plate and to the piston chambers. ogether with the pressure spring and the system pressure, the reaction ring (8.) is used to adjust the clearance. his achieves a very high temperature shock stability and unchanging performance values for the entire service life. Leakage Minor leakage at the pistons and control unit in housing F () must be drained via the case drain port (C).

5 + (0) Hydraulic fluid MR, MRE Hydraulic fluid HLP mineral oil according to DIN Part Prior to project planning, please refer to the detailed information in our data sheet RE 900 concerning the choice of hydraulic fluid. Please contact us if the unit is to be operated with HFB or HFC hydraulic fluid or with biologically degradable hydraulic fluid. FKM seals are required if the unit is to be operated with phosphoric acid ester (HFD). We recommend you to choose the operating viscosity (at operating temperature) in the optimum range for efficiency and useful life of ν opt = optimum operating viscosity mm /s relative to the circuit temperature in a closed circuit, the reservoir temperature in an open circuit, and the temperature in the motor housing (case drain temperature). he following values for viscosity apply in extreme cases: ν min = 0 mm /s in case of emergency, short-term ν min = 8 mm /s with reduced performance data ν max = 000 mm /s short-term for cold start Details regarding the choice of hydraulic fluid he correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature. in a closed circuit, the circuit temperature; in an open circuit, the reservoir temperature. In order to achieve maximum continuous power values, the hydraulic fluid viscosity has to be in the range of the optimum operating viscosity, relative to both the inlet temperature and the case drain temperature. Example At an ambient temperature of X C, the operating temperature (closed circuit: circuit temperature, open circuit: reservoir temperature) will settle to 0 C. In the optimum operating viscosity range (ν opt ; shaded area), this corresponds to the viscosity classes VG 6 or VG 68; to be selected: VG 68. Note he case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature or reservoir temperature. At no point of the component may the temperature be higher than 80 C, however. If these conditions cannot be maintained at extreme operating parameters or due to a high ambient temperature, our advice is to flush the case, even outside the specified range (see diagrams on pages 0 to ). Consult us if necessary VG68 - VI Viscosity ν [mm /s] VG 00 - VI νopt VG 0 - VI 00 VG 68 - VI 00 VG 6 - VI 00 VG - VI 00 VG - VI emperature t [ C] t min = -0 C Hydraulic fluid temperature range t max = +80 C Viscosity range according to DIN ISO 8 RE 8/08.0, Bosch Rexroth AG Company Registered in England No: 6769 VA Registration No: 7 69 BS EN ISO 900:008 No: LRQ 09689

6 + (0) MR, MRE Hydraulic fluid he finer the filtration, the higher the cleanliness level of the hydraulic fluid and the longer the service life of the radial piston motor. o ensure functional reliability of the radial piston motor, the hydraulic fluid must have a cleanliness level of at least: 6 according to SAE, ASM, AIA 9/6/ according to ISO 06 he lower the speed and the case drain pressure, the longer the service life of the shaft seal. he limit value for the permissible case pressure is p max = bar regardless of motor speed. For higher case pressures, a shaft seal suitable for up to p max = bar may be installed (ordering code F). For further information about flushing the case, please refer to page 9. Some hydraulic fluids require the use of FKM seals and shaft seals (type: HFD...). We recommend the use of FKM shaft seals at high operating temperatures in order to prolong the service life.

9 + (0) Case flushing MR, MRE 9 Case flushing Case flushing is necessary to achieve maximum continuous power values (see diagrams on pages 0 to ). Under certain conditions and to maintain the recommended operating viscosity of 0 to 0 mm /s in the housing, it may be necessary to flush the motor even outside the specified range (see page ). A simple way of checking this is to measure the surface temperature θ A + C. At high continuous power, case flushing is also recommended outside the specified range. Maximum permissible case pressure: bar (cf. page 6). Please consult the echnical Product Management department regarding the choice of an appropriate throttle diameter.
