ZGM3-425 ZGM3-500 Internal Five-star Motor Piston Oil Motor
Core Features 1. Efficient and stable: Adopting an axial plunger structure, it has high volumetric efficiency and good low-speed stability. 2. High pressure resistance: Strengthen bearing and sealing design to adapt to continuous high-pressure operation. 3. Wide application: Suitable for construction machinery (such as excavators, cranes), mining equipment, ship deck machinery, etc. 4. Easy maintenance: Modular design, key components can be quickly replaced.
Basic characteristics
-Structure type: The internal five-star motor belongs to the radial piston hydraulic motor, which generates rotation through the reciprocating motion of the piston on the five-star (or more star shaped) cam track.
-Low speed and high torque: suitable for directly driving heavy equipment (such as winches, walking mechanisms, etc.) without the need for a gearbox.
-High reliability: Designed to be sturdy and suitable for harsh working conditions such as mining and construction machinery.
Typical parameters (subject to actual technical manual)
-Displacement: Approximately 300-500 mL/r (assuming "3" represents displacement level).
-Working pressure: The rated pressure may be 20-35 MPa, with a higher peak pressure.
-Output torque: 425 may correspond to the rated torque (such as 425 N · m @ certain pressure).
-Speed range: Usually low-speed type, rated speed 100-300 rpm.
-Installation method: flange installation, shaft output (keyway or spline).
Application scenarios
-Construction machinery: excavator rotary mechanism, concrete pump truck mixing system.
-Agricultural machinery: harvester walking drive, straw baler.
-Ship equipment: winches, anchors.
