Product Features:
Adopt the design of floating balnace with rotation valve distribution technologies, guarantee the high efficiency. stablity and durability of the oil distribution system even under working conditions of high pressure, high speed and mechanical shock.
The pressurized hydraulic fluid columns are finely set up with the spherical eccentric crankshaft and the spherical surfaces of the piston covers. The design significantly reduces the wear of friction pairs, reaching smooth and higher working efficiency.
Special plasma coating treatment quarantees the effective lubrication and wear-resistance of the spherical surface of crankshaft. enhances volumetric and mechanical efficiency together with longer service life
Range of application
Can be widely used in hydraulic transmission system of ship building, plastic machinery, mining.
construction metallurgy, petroleum, coal mine, geological drilling and other industries.
Product Advantages：
1) Due to the absence of lateral forces between the piston and the swing cylinder, the bottom of the piston is designed for static pressure balance, and torque is transmitted between the piston and the crankshaft through rolling bearings, all of which reduce friction loss during the transmission process. Therefore, the CM series hydraulic motors have high mechanical efficiency and high starting torque (with a mechanical efficiency of over 0.92 at startup).
2) The flat distributor is simple and reliable, improving sealing performance, which results in good low-speed stability and minimal leakage. The piston and swing cylinder are sealed with plastic piston rings ensuring no leakage, leading to high volumetric efficiency (up to 0.98).
3) By structurally reducing friction loss and improving sealing performance, the hydraulic motor maintains good low-speed stability, can operate smoothly at 1 r/min, and has a wide speed adjustment range (with a speed adjustment ratio of up to 1000).
4) Since the piston and bearing sleeve are tightly secured without gaps through the snap ring, this series of hydraulic motors can operate in pump conditions. When the oil inlet is closed, the motor can run at high speed in a freewheeling state.
5) This series of hydraulic motors can handle high pressure, with a maximum pressure reaching up to 45 MPa. They are lightweight, compact, and powerful.
6) Due to the simple structure, rational design, and the use of bearings with high load capacity, these motors are reliable in operation, long-lasting, low in noise, and the drive shaft can bear radial loads, with reversible rotation direction.
