The Theoretical Research And Experiment Of Double-Stators Single-Roller Hydraulic Motor

With the hydraulic transmission and control technology continues to evolve, the performance of the hydraulic motor put forward higher requirements.Traditional hydraulic motor is a rotor corresponds to a stator only way to achieve a kind of output, and this new type of hydraulic motor is a rotor corresponds to the composition of two stator can be multiple speed and torque output. The most advantage characteristic of this motor is that it consist by one rotor and two stators (one called external stator and the other called internal stator) In this case, more power mass ratio can be obtained than one single stator motor produced. As the motor has two stators and thus able to obtain two or more of the torque and speed. In this case, more power mass ratio can be obtained than one single stator motor produced. And to achieve a special differential output. Extends the scope of application and motor performance parameters.The analysis of a new pair of stator a hydraulic motor works, and its structure and movement characteristics, and analysis differs from traditional the motor of the connection, especially the new connect to this approach. Kinematics analysis: Based on Theoretical Mechanics we get the track, velocity, acceleration of the roller.Dynamics analysis: According to Theoretical Mechanics and Hydrodynamics, we analyze the liquid pressure, solid pressure and inertia force, and get the expressions of them.Use MATLAB number of different roller hydraulic motor for flow and displacement simulation, and have done a detailed analysis, drawn this roller and flow and pulse of hydraulic motors, Last verified through testing of the correctness of the principle of hydraulic motors.
