Design of Double Helix Swing Hydraulic Cylinder

YU Yan-dong;Jiangyin Hongteng Machinery Co.,Ltd.;  
Double helix swing hydraulic cylinder is hydraulic actuator which converts the linear motion of piston into swing of output rod.It has the advantages of small size,large output torque,high accuracy of swing angle and easy to assemble.Introduces the working principle of the double helix swing hydraulic cylinder,and derives the mathematical model of the output torque and the output Angle of the double helix swing hydraulic cylinder.Based on the performance requirements of one swing hydraulic cylinder,confirmed the dimensions of two level helix pair of the swing hydraulic cylinder,and calculated the actual output torque and maximum swing angle.According to the experimental data,analyzed the relationship between the output torque of swing hydraulic cylinder and working pressure,friction and other influencing factors.
