Transcription

1 High torque low speed vane motors (multi-torque type) MHT Functional Symbols Special switching valves enables easy switching from low speed high torque to high speed low torque. alanced type vane motor provides wide range of speeds and torques. Compact with large torque output. Smooth, stable low speeds even at rpm. Compact design which eliates need for gear boxes and reduction gears.

6 Port Connection and Torque Switching When using special switching valve Input port, outlet port (For left (CCW) rotation of MHT//, inlet and outlet ports are reverse). Switch lever only after motor is stopped. Lever should be switched fully until it contacts stopper pin. Tighten fixing bolt. Lever position and torque relationship is shown in the below table. モータ形式 Motor Model Torque トルクの切換状態 Switching Condition Max. 最高トルク Torque High 高トルク Torque Medium 中トルク Torque Low 低トルク Torque Stop 停止 MHT4// MHT// -speed 速形 ll 上記を除く speeds 速形全て models except for above model.

See dimensions for information on bolt tightening torque. Drain Drain should be piped directly to tank. Drain line allowable back pressure is.7 MPa. When motor is used at. MPa and under, or rpm and over, confirm that drain flow is above values given in the table below. If drain flow is low, raise back pressure on motor outlet and increase drain flow.

Torque Condition Port Port Port Full Torque Low speed, high-torque Inlet Inlet Medium speed, medium torque Outlet Inlet Outlet Partial Torque High speed, low torque Inlet Outlet lways use special switching valve for MHT7///7 and MHT/7/. When using MHT// with left hand rotation, the port connections shown in the above left table should be reversed. Rotation direction Uni-directional, either right (standard) or left rotation. Motor cannot be operated in both directions (except for MHT//). ote: Consult Tokyo Keiki for left hand rotation motor. Motor cannot be used as brake (pump). ack pressure Use a check valve, etc. to keep the motor outlet side pressure within the. to. MPa range. Temperature difference between motor and oil must be kept below 8 C. In any case motor is cool and oil temperature is high, run motor free from load at low speed ( - or under) until the temperature difference drops within the 8 C range. For initial startup, fill oil from each port and operate after motor is completely filled with oil. See Vane Motor otes on Operation (page -). -
