Precautions for Selecting DOWMAX OWMAX Motors

ME100 ME150 ME175

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. Brake torque shown in this catalogue is for the brake pilot line pressure of 0kgf/cm2.

4) Operation exceeding the operating conditions (pressure and speed) corresponding to the desired life of motor. Check the bearing life diagrams shown in this catalogue for confirmation.

6) Operation that causes the case temperature to exceed 80℃. ＊Never remodel motors.

CAUTION ＊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). As in the case of water-glycol type hydraulic fluid, the motor life can substantially be shortened depending on the type of fire-resistant fluid. (Contact 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. Refer to the related instruction manual for the filter specifications.

1

＊Precautions regarding the drain port position and drain piping are described in the related instruction manual. Be 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.

＊When installation of motor with its shaft facing upward is desired, select "D OWMAX for installing the shaft upward" (mentioned before) that permits air bleeding from the case. ＊Keep the drain pressure inside the motor case below 0.3MPa (3 kgf/cm2). 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.

3) Operation exceeding the allowable external force (radial and thrust load). Refer to the shaft strength diagrams shown in this catalogue for confirmation.

5) Operation in cold places (below -25℃) (Contact us for special motors for operation at temperatures from -25℃ to -45℃.)

5) 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.)

4) 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. (For example, a load will drop suddenly.) Use a mechanical brake, as necessary in these cases.

3) Brake 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.

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. Check the brake torque periodically, and replace the brake friction plates with new ones, if necessary.

3. The graphs shown are the bearing life (B-10 Life) at 100 rpm shaft speed (500 rpm only for ME100) for various pressures and radial loads. When the shaft speed differs from 100 rpm (500 rpm only for ME100) the bearing life can be obtained by the following formula: (Bearing Life obtainable in 100 (500 for ME100) B-10 Life ＝ the graph) × Actual Shaft Speed, rpm In case where the side load acts at a different location to the midpoint of the shaft projection please refer to us.


NOTE 1. If motors are operated within the proper ratings and conditions, the operational life is determined by the Bearing Life. 2. In order to maintain the maximum bearing life, when a radial load is imposed on the output shaft the motor should be installed as illustrated in Fig. 2 or Fig. 3; For a uni-directional application, motor should be installed so that side load acts as shown in Fig. 2. For a bi-directional application, a radial load for each rotational direction being applied, the motor should be installed so that side loads act as shown in Fig. 3.

Construction & Working Principle Piston Casing

Spring Cylinder block

Slipper

In the Fig. 1 the high pressure fluid flowing in from the main port enters through the passage in the thrust retainer plate. 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.

Fig. 1 Flow of high pressure fluid

Fig. 2 shows a case of large displacement. When high pressure fluid is fed to the pilot pressure port B, it arrives at the pilot piston chamber 3 through the passage 1 and 2, 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 7. The groove 9 on the main spool comes to the position shown in Fig. 2. With this movement of the main spool, the high pressure fluid coming from the main port flows into both passages of 10 and 11 and exerts force on the right and left pistons, thus working as a large displacement motor.

Fig. 3 shows a case of small displacement. When high pressure fluid is fed to the pilot pressure port A, it flows to the pilot piston chamber 5 through the passage 4 , 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 7. The groove 9 on the main spool comes to the position shown in Fig. 3. With this movement of the main spool, the high pressure fluid coming from the main port flows only to the passage 10, 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 12. Further, as the passage 12 is connected with the hole 13, fluid is supplied and cooled through the flow to the drain.

CHANGE-OVER CIRCUIT IN 2-SPEED OPERATION [Example of 2-speed change-over circuit] 1. Where a F2 flange with solenoid valve is used.

[Basic conditions of a changeover operation]

1. The change-over pilot pressure is basically self-pressure. However, when a separate pilot pressure other than system-pressure is used, it must be higher than the system-pressure. 2. When the system-pressure is utilized as the pilot pressure for the change-over, the change-over can not be done if the system-pressure is below 1MPa (10 kgf/cm2). (If back-pressure exists at the low pressure side of the change-over pilot pressure, the system-pressure must be larger than the back pressure by 1MPa (10 kgf/ cm2) or more.)

Counter Balance Valve with Brake Valve

Structure of cartridge type mechanical brake (BB, BC, BP, BR 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.

61

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. CAUTION; 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.

The Brake torque is generated in proportion to the force exerted between the friction plates and steel plates. Therefore, the brake torque varies with the pressure at the brake releasing port and the drain pressure in the motor case. The chart, right, shows the relationship between the brake torque vs. the pressure at the brake releasing port and the drain pressure in the motor case. Brake torque varies due to unevenness of friction coefficient between friction plate and steel plate. The curve shows the lower limit of these values.

NOTE 1. If motors are operated within the proper ratings and conditions, the operational life is determined by the Bearing Life. 2. Bearing life varies due to the direction of radial load to shaft. 3. The graphs shown are the bearing life (B-10 Life) at 500 rpm shaft speed for various pressures and radial loads. When the shaft speed differs from 100 rpm the bearing life can be obtained by the formula below: 500 B-10 Life = (Bearing Life obtainable in the graph at 500 rpm) × Actual Shaft Speed, RPM In case where the side load acts at a different location to the midpoint of the shaft projection please refer to us. 4. Applications with axial thrust loads should be referred to us. 5. 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.

□Rated output torque and peak output torque is 95% of efficiency □For the service life refer other catalogue in conjunction with this catalogue as life varies with different models. Rated speed is suitable for the rated pressure. In case of low pressure used continuously, there are other models also suitable for application according to use. Please enquire for any further requirement. □This catalogue is exclusively for Shield Cutter Drive. Therefore useful for Horizontal use only. In case of requirement of shaft in Upward or Downward direction please enquire as it becomes special specification. □In case DOWMAX motors of this series are required to be used for the operation other than cutter and that of Shield Tunneling please discuss with us. □DOWMAX motor with Planetary Gear can also be built with other reduction ratio as well as torque specification than those mentioned in the catalogue. We appreciate your enquiry for these models.

Series Code

When the directional valve is switched to either direction to accelerate the hydraulic motor, assuming that the valve is switched to the (a) side, the fluid will be introduced to the Av port. Then, the fluid is directed to the spring chamber As at the edge surface of the main spool through the pilot passage Ap of the counter balance valve and thus, the main spool will move to the right direction. Then, the fluid flown into the Av port is introduced to the hydraulic motor from the AM port through the check valve in the main spool. As the hydraulic motor cannot absorb all the fluid flown into the Av port until acceleration has been completed, the fluid pressure will rise upto the relief valve set pressure and the excessive fluid is discharged to the return line from the relief valve Ra.

Ra Rb Main spool

(During neutral brake) When the directional valve is returned to the neutral position, the pressure of Av and Bv become equivalent, reaching the tank pressure and thus the main spool of the counter balance valve will be pushed back to the neutral position by the spring force. As the return line is closed by the check valve in the main spool, the pressure at the return side will be raised upto the relief valve set pressure and the hydraulic brake is applied to the motor to stop rotation.

(Prevention of overrun) When the hydraulic motor is going to overrun exceeding the pump discharge volume due to external loads, the pressure at the inflow side decreases and the main spool will return to the neutral position. Thus the brake is applied to the hydraulic motor and overrun is prevented.

2. One-directional Counter balance Valve CW300A （During Rolling up） Load

When the directional valve is switched to the (a) side and the fluid is introduced from the Av port, the fluid will be directed to the hydraulic motor inlet from AM port through the check valve in the counter balance valve, and the load will be raised. The fluid drained from the hydraulic motor outlet will be discharged to the Bv port through BM port.

（During Rolling down） When the directional valve is switched to the (b) side, the fluid will be flown into the Bv port. The fluid introduced to the Bv port is directed to the main spool end surface through the pilot passage Bp. If the pilot pressure becomes higher than the spool spring force, the main spool will move to the left and the return side passage will be opened. The fluid flown into the Bv port is introduced to the hydraulic motor inlet through the Bm port and the load is lowered. The fluid discharged from the hydraulic motor outlet is drained to the Av port through the AM port. When the load is going to overrun exceeding the pump discharge volume due to gravity, the pressure at the inflow side of the motor is reduced and the pilot pressure decreases. Thus, the main spool is returned to the right side by the spring force and the return line is closed, which generates the pressure at the outlet side of the hydraulic motor and overrun is prevented.
