[Abstract]:Higher energy efficiency and more economical way of energy saving are the unremitting pursuit of industrial production. The hydraulic planetary gear compound transmission device developed by Voith Company in Germany combines the adjustable hydraulic gear system with the planetary gear system and realizes the perfect combination of hydraulic transmission and mechanical transmission according to the principle of power shunt. It is a technology with wide range of application, high efficiency, stable performance, high reliability and high transmission power. In this paper, the system characteristics and application of the technology are studied, and the matching analysis under typical working conditions is carried out in order to further develop and apply the device. At first, the paper discusses the combination mode and structure of three kinds of hydraulic transmission elements and planetary gear with high speed, low speed and constant speed, and discusses the characteristics of different structures and different working characteristics. The matching relationship between the working characteristics and the load characteristics of the device is analyzed. The kinematic characteristics of the hydrodynamic planetary gear transmission device under three working conditions are analyzed, and the relationship between the transmission ratio, the efficiency, the working point and the main parameters of the torque converter and the characteristic parameters of the planetary gear train is deduced. Secondly, the paper studies the application of high-speed output hydrodynamic planetary gear compound drive device in electric boiler feedwater pump and centrifugal pressurized compressor, and compares the speed regulation of this device with hydraulic coupler speed regulation and frequency conversion speed regulation. Efficiency analysis, cost analysis and reliability analysis are carried out, and the advantages and disadvantages of the device in high speed and high power applications are obtained. The application feasibility of low speed output device in reciprocating compressor is analyzed. In the last part of the paper, the matching analysis of low speed and high speed output devices is carried out in combination with the kinematics characteristics of the device, and the reference hydraulic model of hydraulic torque converter that meets the design requirements is preliminarily determined, and the main structural parameters of the high speed output device are calculated. In this paper, a comprehensive and systematic analysis of the hydraulic planetary gear transmission device is made, and a preliminary matching calculation and structural design are carried out, which will lay a good foundation for the development of the hydraulic planetary gear composite transmission technology in the future.
