Description

technical field [0001] The invention relates to the field of electric cylinders, in particular to an electric cylinder for magnetic transmission. Background technique [0002] At present, the electric cylinder is a kind of linear actuator in industrial automation equipment. It transmits the power of the servo motor to the screw through the transmission mechanism, and then converts the rotary motion of the screw into the linear motion of the nut through the screw and nut mechanism. , and then transmitted to the piston rod, so as to realize the telescopic movement of the piston rod relative to the cylinder. Compared with common hydraulic cylinders, pneumatic cylinders, etc., the electric cylinder responds quickly and has high execution accuracy. However, the screw rod of the traditional electric cylinder belongs to a single support structure, and the stability of the pressure rod is poor. The movable end screw rod is easily shaken by centrifugal force Friction with the piston...
