1. GENERAL DESCRIPTIONThe HMB010 fixed displacement motoris currently the smallest of 12 framesizes in the Kawasaki “Staffa” range ofhigh torque, low speed radial pistonmotors which extends from 94 to 6800cm3/r (5.76 to 415 in3/r) capacity. Therugged, well-proven designincorporates hydrostatic balancingtechniques to achieve high efficiency,combined with good breakout torqueand smooth running capability.

Various features and options areavailable including, on request,mountings to match competitorinterfaces.

The HMB010 is capable of torqueoutputs up to 685 Nm (505 lbf ft) andspeeds to 500 r/min with a continuousoutput of up to 25 kW (33 hp).

The Kawasaki “Staffa” range alsoincludes dual and continuously variabledisplacement motors, plus matchingbrakes and gearboxes to extend theavailable torque range.

RATING DEFINITIONS

● CONTINUOUS RATINGFor continuous duty the motor must beoperating within each of the maximumvalues for speed, pressure and power.

● INTERMITTENT RATINGOperation within the intermittent powerrating (up to the maximum continuousspeed) is permitted on a 15% dutybasis, for periods up to 5 minutesmaximum.

● INTERMITTENT MAX. PRESSUREUp to 241 bar (3500 psi) is allowable on the following basis:(a) Up to 50 r/min: 15% duty for

periods up to 5 minutes maximum.(b) Over 50 r/min: 2% duty for periods

up to 30 seconds maximum.

The torque curves indicate themaximum output torque and powerof a fully run-in motor for a range of pressures and speeds whenoperating with zero outlet pressureon petroleum oil of 50 cSt (232 SUS)viscosity. High return line pressureswill reduce torque for a givenpressure differential.

BEARING LIFE

The nomograph allows the median▲

bearing life to be determined forconditions of:1. No side load and no axial thrust2. Side load and no axial thrust▲ To determine L10 life predictions per ISO 281-

1-1977 multiply the median figure by 0.2.

For more precise life prediction, orwhere axial thrusts are incurred, acomputer analysis can be provided by Kawasaki on receipt of machineduty cycle.

● SHAFT STRESS LIMITThe shaft stress limit in the nomographis based on the fatigue rating of shafttypes “S” and “P”. Infrequent loadingabove these limits may be permitted;consult Kawasaki.

This nomograph enables the averagevolumetric efficiency, crankcase (drain)leakage and “winch slip”/shaft creepspeed to be estimated.

Example (follow chain dotted line):Given:1. Pressure ................... 175 bar (2500 psi)2. Speed ............................................ 100 r/min3. Viscosity ...................... 50 cSt (232 SUS)

To obtain:4. Volumetric efficiency ......................... 94.25. Crankcase leakage ............... 0.451/min

(27.4 in3/min)6. Shaft creep speed ................... 6.4 r/min

The shaft creep speed occurs when theload attempts to rotate the motoragainst closed ports as may occur, forexample, in winch applications.

5. CIRCUIT ANDAPPLICATION NOTES

STARTING TORQUESThe starting torques shown on thegraph on page 3 are average and will vary with system parameters.

LOW SPEED OPERATIONMinimum operating speeds aredetermined by load conditions (load inertia, drive elasticity, etc.). For operation at speeds below 20 r/min consult Kawasaki.

HIGH BACK PRESSUREWhen both inlet and outlet ports arepressurized continuously, the lowerpressure in one port must not exceed70 bar (1000 psi). Consult Kawasaki on applications beyond this limit. Notethat high back pressures reduce theeffective torque output of the motor.

BOOST PRESSUREWhen operating as a motor the outletpressure should equal or exceed thecrankcase pressure. If pumping occurs(i.e. overrunning loads) then a positivepressure, “P”, is required at the motorinlet ports. Calculate “P” from:

P (bar) = 1 + N2 + C bar22 600

P (psi) = 14.5 + N2 + C psi1560

Where:N = speed, r/minC = crankcase pressure

The flow rate of oil needed for themake-up system can be estimated from the crankcase leakage figure (see Volumetric Efficiency graph onpage 5). Allowance should be made for other system losses and also for“fair wear and tear” during the life of the motor, pump and other systemcomponents.

COOLING FLOWOperation within the continuous ratingsdoes not require any additional cooling.

For operating conditions above“continuous”, up to the “intermittent”ratings, additional cooling oil may berequired. This can be introducedthrough the spare crankcase drain holeor, in special cases, through the valvespool end cap. Consult Kawasaki aboutsuch applications.

MOTOR CASING PRESSUREWith the standard shaft seal fitted, the motor casing pressure should not exceed 3,5 bar (50 psi). Oninstallations with long drain lines a relief valve is recommended toprevent over-pressurizing the seal.

Notes:1. The casing pressure at all times must notexceed either the motor inlet or outlet pressure.2. Check installation dimensions (page 8) formaximum crankcase drain fitting depth.

6. HYDRAULIC FLUIDSDependent on motor (see Model Codeposition ) suitable fluids include:- Antiwear hydraulic oils- Phosphate esters (HFD fluids)- Water glycols (HFC fluids) ▲- 60/40% water-in-oil emulsions

(HFB fluids) ▲- 5/95% oil-in-water emulsions

(HFA fluids) ▲

▲ Reduced pressure and speed limits, see page 3.

Viscosity limits when using any fluidexcept oil-in-water (5/95%) emulsionsare:Max. off load .......... 2000 cSt (9270 SUS)Max. on load ................ 150 cSt (695 SUS)Optimum ........................... 50 cSt (232 SUS)Minimum ........................... 25 cSt (119 SUS)

PETROLEUM OIL RECOMMENDATIONSThe fluid should be a good hydraulicgrade, non-detergent petroleum oil. Itshould contain anti-oxidant, anti-foamand demulsifying additives. It mustcontain antiwear or EP additives.Automatic transmission fluids and motor oils are not recommended.

7. TEMPERATURE LIMITSAmbient min. ......................... –30°C (-22°F)Ambient max. ....................... +70°C (158°F)

Max. operating temperature rangePetroleum Water-oil containing

Min. –20°C (–4°F) +10°C (50°F)

Max.* +80°C (175°F) +54°C (130°F)

* To obtain optimum service life from both fluidand hydraulic system components 65°C(150°F) normally is the maximum temperatureexcept for water-containing fluids.

8. FILTRATIONFull flow filtration (open circuit), or fullboost flow filtration (closed circuit) toensure system cleanliness of ISO4406/1986 code 18/14 or cleaner.

9. NOISE LEVELSThe airborne noise level is less than66,7 dB(A) DIN (70 dB(A) NFPA)throughout the “continuous” operatingenvelope.

1

Where noise is a critical factor,installation resonances can be reducedby isolating the motor by elastomericmeans from the structure and thereturn line installation. Potential returnline resonances originating from liquidborne noise can be further attenuatedby providing a return line back pressureof 2 to 5 bar (30 to 70 psi).

10. POLAR MOMENT OFINERTIA

Typical data: 0,0076 kg m2 (26 lb in2).

11. MASSApprox., all models: 40 kg (88 lb).

12. INSTALLATION DATAGENERAL

● SpigotThe motor should be located by themounting spigot on a flat, robustsurface using correctly sized bolts. Thediametral clearance between the motorspigot and the mounting must notexceed 0,15 mm (0.006 in). If theapplication incurs shock loading,frequent reversing or high speedrunning, then high tensile bolts shouldbe used, including one fitted bolt.

● Bolt torqueThe recommended torque wrenchsettings for the mounting bolts are:M14 ........... 160 ±21 Nm (116 ±15 lbf ft)M12 ...................... 97 ±7 Nm (70 ±5 lbf ft)1/2" UNF ............. 97 ±7 Nm (70 ±5 lbf ft)

● Shaft couplingWhere the motor is solidly coupled to ashaft having independent bearings theshafts must be aligned to within0,10 mm (0.004 in) TIR.

CRANKCASE DRAIN

Motor axis horizontal

The crankcase drain must be takenfrom a position above the horizontalcentre line of the motor.

Axis vertical, shaft up

Additional drainport G1/4" (BSPF)

0,35 bar (5 psi)

Standard drain port G3/8" (BSPF)

An additional drain port is providedwhen the “V” (shaft verticallyupwards) designator is given afterthe shaft type letter in position of the model code. This additionaldrain should be connected into themain motor casing drain linedownstream of a 0,35 bar (5 psi)check valve to ensure lubrication ofthe upper bearing, see abovediagram.

3

Axis vertical, shaft down

Use any drain position. The drainline should be run above the levelof the uppermost bearing; if there isrisk of siphoning then a siphonbreaker should be fitted.

START-UPFill the crankcase with system fluid.Where practical, a short period (30minutes) of “running-in” should becarried out.
