Travel motor characteristics and product application

    The strength of the SP travel motor housing increases, and the internal dynamic component load capacity increases. This feature gives the series a high continuous power range. Due to the high mechanical efficiency and volumetric efficiency, while reducing the internal unit load force, heat generation and the associated negative effects are reduced. Its main features are as follows:

1. Since there is no lateral force between the piston and the pendulum cylinder, the bottom of the piston is designed to be static pressure balanced, and the torque is transmitted between the piston and the crankshaft through the rolling bearing, which reduces the friction loss during the force transmission. Therefore, the SP series final drive motors are characterized by high mechanical efficiency and high starting torque (more than 92% mechanical efficiency at start-up).

2. The plane distributor is simple and reliable, with good sealing and few leakage. The piston and the pendulum cylinder are sealed with a plastic piston without leakage, resulting in high volumetric efficiency (up to 98%).

3. Since the friction loss is reduced in structure and the sealing performance is improved, the low speed stability is good, and the operation can be smoothly operated under the condition of 10 r/min, and the speed adjustment range is large (the speed adjustment ratio can reach 1000).

4. Since there is no gap between the piston and the bearing sleeve through the snap ring, the series of final drives can be operated under the pump condition. When the oil inlet is closed, the motor can run at high speed under the free wheel condition.

5. The hydraulic motor of this series has high pressure and the highest pressure can reach 31.5MPa. Light weight, small size and high power.

6. Due to the simple structure and reasonable design, the bearing with large capacity is adopted, so the work is reliable, the service life is long, the noise is low, the transmission shaft is allowed to bear the radial force, and the rotation direction is reversible.

The scope of products:

    Because SP series hydraulic motors have the above-mentioned series of characteristics, they are widely used in plastic machinery, light industrial machinery, metallurgical machinery, mining machinery, lifting and transportation equipment, heavy machinery, petroleum coal mining machinery, ship deck machinery, machine tools, geological drilling equipment, etc. Various mechanical hydraulic drive systems. https://www.spfinaldrives.com/
