The MR and MRE hydraulic motors are externally pressurised radialpiston motors with a fixed swept volume.
Design
The main components are housing (1), eccentric shaft (2), cover (3),control housing (4), roller bearing (5), cylinder (6), piston (7) andcontrol (8.1; 8.2; 8.3).
Inlet and return of operating fluid
The operating fluid is fed to and returned from the motor via ports Aor B. The cylinder chambers (E) are filled or drained via the controland the channels (D) in the housing (1).
Rotary group, torque generation
The cylinders and the pistons support themselves on the sphericalareas of the eccentric shaft and the cover. It is thereby possible forthe piston and cylinder to align themselves, free from side forces, asthe shaft rotates, together with hydrostatic unloading of the pistonsand cylinders results in friction being minimised and very highefficiencies are achieved.
The pressure in the cylinder chambers (E) acts directly on the excentricshaft. Of the 5 cylinders 2 or 3 are respectively connected with thesupply or return sides.
Control
The control consists of the control plate (8.1) and the distributorvalve (8.2). Whilst the control plate is fixed to the housing with pins,the distributor valve rotates at the same speed as the eccentric shaft.Drillings in the distributor valve form the connection to the controlplate and to the piston chambers. The reaction ring (8.3) acts togetherwith the compression spring and the system pressure and effectivelycompensates for play. This results in a very high temperature shockresistance and constant performance values during the entire servicelife.
Leakages
The low leakage within the housing F (1) which occurs at the pistonand the control must be returned via the leakage port (C).

Direction of rotation Clockwise/anti-clockwise - reversible
Pressure fluid HLP mineral oil to DIN 51 524 part 2; HFB and HFC as well asbio-degradable fluids on request;with phosphate ester (HFD), FKM seals are necessary
Pressure fluid temperature range °C – 30 to + 80
Viscosity range mm2/s 18 to 1000, recommended operating range 30 to 50 in motorhousing, must be adhered to with high constant powers
Cleanliness class to ISO codes Maximum permissible pressure fluid degree of contamination isto ISO 4406 class19/16/13
In order to achieve the maximum constant performance valueshousing flushing is necessary (see diagrams on pages 9 to 19).Under special conditions as well as for the adherence to therecommended operating viscosity of 30 to 50 mm2/s in the housing
flushing of the motor housing outside of the forseen range may benecessary (see page 8). A simple method to check this is by measuringthe surface temperature ϑA (as shown). The temperature insdie thehousing is approx. ϑA + 3°C.
With high continuous powers flushing of the housing is alsorecommended outside the foreseen range. The maximum permissiblehousing pressure is 5 bar (also see page 8). To select the appropriateorifice diameter please consult the Technical Sales Dept.

Pressure fluid technical data
Pressure fluid
See catalogue sheet RE 07 075 for detailed information regardingthe selection of pressure fluids before carrying out any engineering/design work.
Further notes on installation and commissioning can be found onpage 36 of this catalogue sheet.
When operating with HF pressure fluids or bio-degradable pressurefluids possible limitations to the technical data must be taken intoconsideration, please consult ourselves.
Operating viscosity rangeWe recommend that the operating viscosity is so selected (at operatingtemperature) that it lies in the optimum range of
νopt = optimum operating viscosity 30...50 mm2/s
for efficiency and service life, referring to the circulation temperaturein closed circuit and the tank temperature in open circuit as well asthe motor housing temperature (drain fluid temperature).
Limiting viscosity rangeFor the limiting conditions the following values are valid:
νmin = 10 mm2/s in emergency, briefly
νmin = 18 mm2/s with reduced performance data
νmax = 1000 mm2/s briefly with cold start
Selection diagram
Choosing the type of pressure fluida prerequisite for the selection of a pressure fluid is that the operatingtemperature in relation to the ambient temperature is known. In closedcircuits the circulation temperature, in open circuits the tanktemperature. To achieve the maximum continuous power values theoil viscosity must be within the optimum operating viscosity range,referring to the inlet temperature as well as the drain oil temperature.
Example:
With an ambient temperature of X °C the operating temperaturesettles to a temperature of 50 °C (closed circuit: circulationtemperature, open circuit: tank temperature). For an optimum viscosityrange this (νopt; raster field ) relates to a viscosity class of VG 46 orVG 68; select: VG 68.
The drain oil temperature which is influenced by the pressure andspeed lies above the circulation or tank temperature. At no point inthe system must this exceed 80 °C.
If the above stated conditions cannot be maintained due to extremeoperating conditions or high ambient temperatures we recommendthat, also outside the foreseen range, housing flushing is used (seediagram on pages 9 to 19), or consult ourselves.
Filtering of pressure fluidThe finer the filtration and the better the cleanliness class that canbe achieved the longer the service life of the radial piston motors.
To guarantee the functional safety of the radial piston motors acleanliness class of at least
6 to SAE, ASTM, AIA
19/16/13 to ISO 4406 is necessary.
Leakage fluid pressureThe lower the speed and the leakage fluid pressure, the longer thelife of the shaft seal ring. The maximum permissible housing pressureis
pmax = 5 bar
which is independent of the motor speed.
For higher housing pressures a shaft seal which is suitable up to apmax = 15 bar can be fitted (ordering code F). Further informationregarding housing flushing can be found on page 7.
Shaft seal ring FKM
Some fluids require the use of FKM sealsand shaft seal rings (type: HFD ...). Werecommend the use of FKM shaft sealrings with high operating temperaturesin order to extend the service life.

K = Service life co-efficient
p = Operating pressure (motor) in bar
LH10 is the norminal service life which 90 % of all bearings exceed.(Values at 36 mm2/s and 45° C). The average service life of all bearingsLH50 is 5 x LH10.

Sensor shaft (2nd shaft end) for speed sensing – connections (dimensions in mm)
Hydraulic motors that are fitted with an incremental transducer aresuitable for use in all application areas where exact sensing of themotor shaft speed is required.
All of the type MR Rexroth motors can be fitted with incrementaltransduers. The solution is a package which includes the motor,incremental transducer control and incremental transducer, all ofwihich has protection to IP 67 (including the connection socket).

Assembly and commissioning guidelinesMounting, connecting
Installation position, optional– Take drain return into acccount
(see below)Correctly align the motor– Mounting surface even, resistant to bendingMin. tensile strength of fixing screws 10.9– Take the stated tightening torque into account
Pipe lines, line connections
Use suitable fittings!– According to motor type, thread or flange connectionsSelect pipe and hose lines according to the applicationconditions!– Take the manufacturers data into account!Before commissioning fill motor and brake with oil– Use prescribed filter!
Note: With frequent stop/start operation or high reversalfrequencies, 2 fixing screws must be tight-fit screws
CouplingMounting with screws
Use thread in output shaft
Take apart with an extractor
Leakage and flushing line installation examplesNote: Install leakage line in such a way that motor cannot run empty.T = Plug Y = Motor housing filling point ← Bleeding
