Research on Distribution Characteristics of Orbit Cycloid Hydraulic Motor with Digital Distribution Mechanism
In traditional orbit hydraulic motor,mechanical flow distribution is used,resulting in high mechanical and volume loss.At the same time,the motor has a large size and difficulty in processing.Based on this,a hydraulic motor that used a high-speed electro-magnet valve group to achieve digital distribution and speed adjustment was studied.The operating mechanism and structural characteris-tics of the digital distributed hydraulic motor were analyzed;on the basis of the theoretical analysis of the orbit motor and the electromag-netic valve flow characteristics,a valve-motor dynamic model was established to simulate the proposed model;on the basis,the charac-teristics of the distribution and steering switching of the orbit motor were studied;by changing the PWM duty cycle,the orbit motor can better achieve two-way speed regulation.Compared with mechanical matching orbit motors,structural complexity of the orbit hydraulic motors with digital distribution has greatly reduced and the flexibility of streaming and speed adjustment is enhanced.
