[Abstract]:Aiming at the disadvantages of the hydraulic motor of coal mine drilling machine such as bulky, low reliability and not being able to use emulsion as working medium, this paper uses non-circular gear drive to solve the problems existing in hydraulic motor. The non-circular planetary gear hydraulic motor is a low-speed and high-torque hydraulic motor. Compared with other types of hydraulic motors, it has the advantages of small volume, oil resistance, high pressure resistance and the use of emulsion as working medium. The study of non-circular gear hydraulic motor is of great significance in expanding the application of non-circular gear, reducing the cost and safety in coal mine production. By analyzing the structure and working principle of the non-circular planetary gear hydraulic motor, the design scheme of the compact and more reliable hydraulic motor is worked out in this paper. The non-circular planetary gear mechanism is designed by using the theory of non-circular gear design. By studying the kinematic relationship of the non-circular planetary gear mechanism, the equation and mathematical model of the joint curve between the solar wheel and the inner gear ring are established, and the model is solved by MATLAB and the figure of the pitch curve is drawn. Based on the generating principle of non-circular gear tooth profile, the formula of tooth profile design analytical method is derived, and the model of non-circular gear tooth profile is established by using the theory of converted tooth profile and AutoCAD / Pro-E software. By studying the motion of the planetary gear train, the velocity and acceleration formulas of the planetary gear and the equation of the motion between the solar wheel and the inner gear ring in the transforming mechanism are obtained. By analyzing the structure of several kinds of non-circular gear hydraulic motors, the structure of 46 type hydraulic motors is determined, and the structure design of oil distribution disk is obtained by using the flow distribution theory of non-circular gear hydraulic motors. The static and dynamic performance of the model is analyzed by establishing the model of valve-controlled motor and using the conservation equation of flow rate and torque. Simulink simulation is used to obtain the curve of flux jump, load jump and rotational speed.
