Network optimization information:

Generally, the ball joint is of sliding shoe plunger structure, the 02 series is of sliding shoe plunger structure, and the ball socket is of plunger structure. This structure increases the displacement by 16% and reduces the volume by 18%.

Domestic hydraulic motors started late. In the early 1960s, foreign countries developed a series of Low speed high torque hydraulic motor JDM series crankshaft connecting rod motor with rated working pressure of 16MPa has been initially formed. However, the structure of the main motion pair is old and its performance is poor. Only a small amount of production has been carried out, and the production progress is slow. In the early 1970s, with the application of construction machinery, construction machinery and mining machinery, Hydraulic motor Technology has been greatly developed. However, due to the lack of understanding of some key motion pairs, they are still designed by drawing, simulation, experience analogy and other methods. Although there are many developers, none of the hydraulic motors passed the test and evaluation. however, Steel ball hydraulic motor Imitating and digesting foreign products provides us with friendly design and production experience. For several key motion pairs that affect the performance and life of the motor, special theoretical and model tests were carried out. For example, the characteristics of various low-speed high torque hydraulic motors were studied, mathematical models and experimental research methods were proposed, and ways to improve their performance were obtained: the supporting mechanism of various key friction pairs of the motor was studied, and a reasonable design method was obtained; The new flow distribution structure of various motors is studied. Cycloidal motor of aerial work vehicle This has promoted the development of high-voltage motors in China. Some scholars have proposed that some low-speed high torque non Plunger type hydraulic motor , such as non-circular gear train hydraulic motor and cone differential hydraulic motor. Some results have been achieved, which has prompted High pressure hydraulic motor Develop in the direction of diversification.
