Abstract: Aiming at the problem that the development of hydraulic robot joint is restricted by joint dimension, movement range and control precision, a hydraulic rotary servo valve was proposed, in which the valve spool stress is balance in radial direction and servo dead zone is small. A hydraulic robot joint was designed based on the hydraulic rotary servo valve. The hydraulic robot joint dimension is compact, and its output torque is larger. The simulation experimental results show that hydraulic robot joint has high response rate, good motion stationarity, high movement precision, and larger load capacity.
Key words: hydraulic rotary servo valve; hydraulic robot joint; compact joint dimension
