Development trend of low speed high torque hydraulic motor in China

The pressure of domestic low speed high torque hydraulic motor is lower than that of foreign similar products at present. For the important motion pairs of various types of motors, there is still a lack of sufficient basic knowledge and experimental research on the mechanism level. Therefore, in the design scheme, the construction, specifications, raw material selection and precision are clear. Rexroth GMH series relies largely on the accumulation of working experience. Problems in the manufacture of the design scheme are often found and dealt with only in the test of the whole motor.


However, at the present stage, China has paid great attention to the digestion and absorption of overseas high quality technology, and gradually designed programs, developed and developed its own new products, resulting in a certain number of technical professional research and production manufacturing team. Start to carry out special basic knowledge and simulation experiment research on some important motion pairs that harm motor performance and service life. For example, a variety of internal curve hydraulic motor slide curve performance and design method research, XYJ hydraulic winch clearly put forward no pulse equal contact pressure curve and other basic theory and design methods, in order to improve the motor performance and service life; Based on the study of various independent variable modes and basic theory of the curve hydraulic pressure motor, the independent variable structure design without pulse is clearly proposed. To create mathematical analysis models for various hydraulic motors, hydraulic vibrators analyze the elements that harm the performance of the motor, and then carry out auxiliary design (CAD); The support mode of crankshaft roller and rack of crankshaft connecting rod hydraulic motor and the bearing force of distribution shaft and distribution plate are analyzed and studied. The support mode of improving output power consumption and the structural design of distribution shaft with balanced tangential force are clearly proposed. The similar basic principle is applied to the hydraulic motor experiment research and the analysis of the results, and then the general design scheme and the basic characteristics and transformation of the hydraulic motor are studied. To carry out research on the unique performance of various low-speed high-torque hydraulic motors, find effective, environmentally friendly and energy-saving experimental methods, and improve the precision of side test, carry out research on the unique performance of various low-speed high-torque hydraulic motors, clearly propose mathematical analysis models and experimental research methods, and get the way to improve performance; To carry out research on the characteristics and principles of important friction pair support of various motors, to obtain effective design methods to improve performance, and to carry out research on the new flow distribution structure of various motors. This kind of research work has promoted the development trend of low speed high torque motor.
