2 INDEX Precautions for Selecting DOWMX OWMX Motors ME ME ME a. Pay attention, when planning hydraulic circuit, to the brake pilot line not being pressurized at any time the brake is necessary, even if it's an instant time. b. When residual pressure remains at the brake pilot line, brake torque decreases proportional to the residual pressure. rake torque shown in this catalogue is for the brake pilot line pressure of kgf/cm. ) Operation exceeding the operating conditions (pressure and speed) corresponding to the desired life of motor. heck the bearing life diagrams shown in this catalogue for confirmation. 6) Operation that causes the case temperature to exceed 8. Never remodel motors. UTION Use the recommended hydraulic fluid shown in instruction manual. When fire-resistant fluid is used, strictly observe the cautions and notes described in the instruction manual. Standard motors cannot be used when phosphate-ester is used as hydraulic fluid. In that case, select the seal code of V or X (seal material: fluororubber). s in the case of water-glycol type hydraulic fluid, the motor life can substantially be shortened depending on the type of fire-resistant fluid. (ontact us for the expected life of motor under specific operating condition.) When the direction of rotation of the motor is to be changed frequently, select models with a spline shaft. Metal chips, sand, and other fine foreign substances contained in hydraulic fluid will reach the sliding surface of the motor, advancing the abrasion of component parts and causing malfunction and seizure of the motor. Prevent entry of dust, and be sure to install a filter in the circuit. efer to the related instruction manual for the filter specifications. Precautions regarding the drain port position and drain piping are described in the related instruction manual. e sure to refer to them and reflect them in the piping plan. When the shaft is exposed to water or seawater, the standard seal will allow the shaft to rust, and the abraded oil seal may cause oil leakage. In such a case, select or specify models made to the double oil seal specifications. SETY PEUTIONS: ead the instruction manual carefully and thoroughly before using the product, and then use it correctly. rake Mechanical 6 M3P ME6S MES6 3- ME- PH-66S--P ME3 PH-S--P ME3 PH-D--P ME6 PH-8D--P ME PH-9D--P ME8 PH-9D--P ME3 PH-D--P 8 8 ME9- PH-D--P ME6- PH-3D--P ME- PH-96D-6-P When installation of motor with its shaft facing upward is desired, select "D OWMX for installing the shaft upward" (mentioned before) that permits air bleeding from the case. eep the drain pressure inside the motor case below.3mpa (3 kgf/cm). Take care the pressure as it rises depending on the tank position and the length and diameter of pipes. The pressure on the low-pressure side of the main port must be higher than the drain pressure. MP M3P ME- PH-6S--P ME- PH-66S--P 3) Operation exceeding the allowable external force (radial and thrust load). efer to the shaft strength diagrams shown in this catalogue for confirmation. ) Operation in cold places (below - ) (ontact us for special motors for operation at temperatures from - to -.) 9 M6-NS - ) Operation exceeding the usable range (pressure and speed). efer to this catalogue for confirmation of limits for respective models. eduction ) Mechanical brake of DOWMX motor is reverse-operation type, the brake is released when brake pilot line is pressurized. M3 M6 ME8S 3- M3-S P- eduction Precautions for mechanical brake. M- MP ) Operation exceeding the viscosity range of - cst. Single ) In cases where the inertial force of a driving body is large, abnormal pressure will be produced. Measure the pressure of the actual motor, and use a brake valve if the peak pressure exceeds the value shown in the catalogue; otherwise the motor shaft, key, and other parts may be damaged. Plan pipe installation in a manner to satisfy matters described in the related instruction manual. Do not plan operation exceeding the usable conditions described in this catalogue. (This does not apply to motors made to special specifications if special mention is shown in the delivery drawing or product specifications.) -Speed Motor Double ) In cases where external load torque is applied to the motor shaft while the motor is at rest, the motor will turn (slip) due to the leakage inside the motor. If there is no supply circuit, cavitation occurs and the motor goes out of control. (or example, a load will drop suddenly.) Use a mechanical brake, as necessary in these cases. 3) rake torque shown in this catalogue is for the use of standard mineral oil as a hydraulic fluid. When other oils such as fire-resistant fluid or special oils contains additive are used, brake characteristics will differ from the value in the catalogue, consult us in the case. ME3 ME9 ME with 3) In cases where the motor is turned by a load, it is necessary to apply boost pressure to the suction line of the motor to prevent cavitation. The boost pressure is subject to the motor speed and the viscosity of hydraulic fluid. In general, apply pressure that exceeds the minimum, boost pressure shown for each model. c. When the brake is used as a dynamic brake, the brake friction plate will be worn. heck the brake torque periodically, and replace the brake friction plates with new ones, if necessary. ME8 ME- PH-96D-6-P ME- PH-96D-6-P ME3 PH-96D-6-P ME3 PH-96D-6-P ME3 PH-D-6-P ME3 PH-D-6-P ME6 PH-D-6-P ME PH-3D-6-P ME8 PH-3D-6-P 8 8 ME8 PH-D-6-P Shield Tunneling pplication ) In cases where high back pressure is applied to the outlet line of the motor in special application, the performance described in the catalogue may not be exhibited. ontact us if the back pressure applied to the outlet line of the motor exceeds.mpa (kgf/cm). b. Usage classified as "Unsafe range" in the "rake Use imit udging Diagram" in the related Instruction Manual, shall be avoided. ME6 ME ME6 ME3 DOWMX. ) The performance curves shown is this catalogue show the summary (average values) of data on motors that have already been run-in. Provide sufficient margin of safety when selecting motors in accordance with specific applications. When motors are mew (before running-in), they may fail to achieve the performance shown in the catalogue. ontact us if that will cause any problem. a. Mechanical brake and hydraulic brake shall not be used together. When mechanical and hydraulic brake are planned to be used together, consult us for the applicability. Planetary-ear heck that the hydraulic system is planned in a manner to satisfy the matters described in the catalogue, instruction manual, delivery drawing, manufacturing specifications, etc. Pay special attention to the following: ) Mechanical brake of DOWMX motor is originally for a static brake use (parking brake). void the use of dynamic brake to the utmost. When dynamic brake is used unavoidably, pay attention to the followings: DOWMX.

It then flows into the port which opens at the shaft end surface which slides against the timing plate, and branches into both right and left cylinders. One flow reaches the piston bores at the right side of the cylinder block, after passing through port holes of the shaft and cylinder block. The other flows into the piston bores at the left side through the groove in the main spool and port holes in the shaft and cylinder block. Thus the drive shaft starts to rotate through the rotation of cylinder block which is caused by the tangential force on the swash plates exerted by the axial movement of pistons (the pistons are located in the cylinder block which is integral with a drive shaft). The low-pressure fluid, after working on the pistons, is pushed back by the pistons in the cylinder bore, flows out from the low-pressure main port, through the passage in the reverse way as it came in. Thrust retainer plate Drive shaft Main port Pilot piston Taper roller bearing Main spool ig. low of high pressure fluid ig. shows a case of large displacement. When high pressure fluid is fed to the pilot pressure port, it arrives at the pilot piston chamber 3 through the passage and, and pushes the pilot piston 6 to the right. With the pilot piston 6 pressed to the right side, the main spool 8 also moves to the right by the piston rod. The groove 9 on the main spool comes to the position shown in ig.. With this movement of the main spool, the high pressure fluid coming from the main port flows into both passages of and and exerts force on the right and left pistons, thus working as a large displacement motor. Main Spool Section ig. ree fluid flow low of high pressure fluid ig. 3 ig. 3 shows a case of small displacement. When high pressure fluid is fed to the pilot pressure port, it flows to the pilot piston chamber through the passage, and pushes the pilot piston 6 to the left. With the movement of the pilot piston 6 to the left side, the main spool 8 also moves to the left by the piston rod. The groove 9 on the main spool comes to the position shown in ig. 3. With this movement of the main spool, the high pressure fluid coming from the main port flows only to the passage, exerting force only on the right pistons thus working as a small displacement motor. In this case, although high pressure fluid does not flow to the left side pistons, it reciprocates in the cylinders repeating suction and discharge stroke along with the shaft rotation. This is made possible because the groove 9 around the main spool is positioned as shown by which each left side cylinder is channelled through the passage. urther, as the passage is connected with the hole 3, fluid is supplied and cooled through the flow to the drain. lange w/o Shuttle Valve (c3/ Port) lange w/o Shuttle Valve (/6- UN- Port) lange w/ Shuttle Valve (c3/ Port) lange w/ Shuttle Valve (/6- UN- Port) Seal ode : No Sign Standard Seal (Nitrile ubber) ode Parallel keyed shaft with screws for key retention plate (Std.)

Steel plate Shuttle valve riction plate rake spring W ounter alance Valve with rake Valve Structure of cartridge type mechanical brake (,, P, types) The internal structure of the mechanical brake is shown above. The friction plates and steel plates are located one side the other, and the braking torque is generated by the friction force applied when the spring presses these plates. The friction plates are placed on the splined drive shaft for cartridge type and on the brake spline for integral shaft type, which are connected to the motor shaft with a key. The steel plates are placed on the brake cylinder for cartridge type and brake plunger for integral shaft type by splines. The braking torque is generated by the force of the spring, and when a pressure higher than a spring force is applied in the brake releasing port, the friction plates and steel plates are separated and the brake is released. When the pressure at the brake releasing port is lowered, the brake plunger is pressed against the friction plate by the spring force, and the brake torque is generated by the friction force between the plates. 6 When this mechanical brake is used as dynamic brake, the friction plate will slip against steel plate, and in some cases excessive heat would be generated by friction. In such a case, please contact us. UTION; In case motors are used as it's output shaft to be positioned upward, some modification would be necessary. In this case, please contact us. 6

If motors are operated within the proper ratings and conditions, the operational life is determined by the earing ife.. earing life varies due to the direction of radial load to shaft. 3. The graphs shown are the bearing life (- ife) at rpm shaft speed for various pressures and radial loads. When the shaft speed differs from rpm the bearing life can be obtained by the formula below: - ife = (earing ife obtainable in the graph at rpm) ctual Speed, PM In case where the side load acts at a different location to the midpoint of the shaft projection please refer to us.. pplications with axial thrust loads should be referred to us.. When motor is used in Meter-Out circuit, pressure in the figure shall be a sum of motor inlet and outlet pressure. 6. When water-glycol fluid is used, bearing life comes remarkably short. In this case please refer to us. 6
