XSM series motor is the company's collection of years of production experience, on the basis of Italian technology design improvement, XSM series motor shell strength increased, internal dynamic components bearing capacity and anti-pollution ability enhanced. This feature gives the series motors a high continuous power range. Due to the high mechanical and volumetric efficiency, while reducing the internal unit load, heat generation and associated negative effects are reduced. Its main characteristics are as follows:
1. As there is no lateral force between the piston and the swing cylinder, the piston bottom is designed as a static pressure balance, and the torque is transmitted between the piston and the crankshaft through moving bearings, which reduce the friction loss in the process of force transmission. Therefore, XSM series hydraulic motors have the characteristics of high mechanical efficiency and high starting torque (mechanical efficiency above 0.92 when starting).
2. The plane valve is simple and reliable, with good sealing performance and little leakage. The plastic piston ring between the piston and the swing cylinder is leak-free and thus has a high volume efficiency (up to 0.99).
3. Composite material bushing with friction reduction and self-lubrication performance (patented technology) is used between the trunnion of the pendulum cylinder and the shaft hole of the back cover and shell. The structure reduces friction loss and improves sealing performance and anti-fouling ability. Therefore, the mechanical efficiency and working reliability of low stability are improved.
4. Because the piston and the bearing sleeve stick firmly through the clasp, there is no gap, so this series of hydraulic motor can operate under the pump condition, when the oil inlet is closed, the motor can operate under the free wheel condition (when the pump condition, the oil pressure needs to be supplemented, which can improve the working reliability).
5. This series of hydraulic motor has high pressure, the higher pressure can reach 35MPa. Light weight, small size, high power.
6. Because of its simple structure and reasonable design, it can use bearings with large load capacity, so it is reliable, long life and low noise. The drive shaft is allowed to bear radial load and the direction of rotation is reversible.
XSM series hydraulic motors are widely used in the hydraulic transmission system of plastic machinery, light industry machinery, metallurgical machinery, mining machinery, lifting and transporting equipment, heavy machinery, petroleum and coal mining machinery, ship deck machinery, machine tools, geological drilling equipment and other machinery. Especially suitable for hoisting capstan, drum drive, all kinds of rotary machinery drive, track and wheel driving mechanism and other transmission machinery.
In this paper, a fuzzy control strategy based on BP neural network prediction is proposed for the relative high nonlinearity, friction, leakage and other variability of continuous rotary motor, which seriously affect the tracking characteristics of operating system.
