This is one kind of low speed high torque radial piston hydraulic motor. It can be widely applied in petroleum industry, chemical industry, mining, shipping, constructing machinery, especially for plastic injection molding machine, hydraulic winch, transmission etc.
High staring torque (mechanical efficiency improved to over 0.9), good stability when low speed.
High volumetric efficiency
Higher mechanical efficiency
Opposite rotating available
Radial and axial load available
Higher kw/kg ratio.
High pressure oil comes into the cylinder, working on the piston, pushing the piston down, the piston is connected to the crankshaft, the crankshaft will turn. Together with oil distributor. When piston walks to its lowest position, the cylinder will get through with the oil tank, then the piston goes back. Total 5 pistons work one by one, the crankshaft will turn continually. When the working oil flows oppositely, the shaft will turn in another direction.
