摘要: 一种高速液压伺服缸,由活塞杆、缸筒、活塞、螺母、丝杠、轴承、紧固螺母、阀体和阀芯组成,其中螺母,活塞和丝杠为前体结构,阀体,阀芯和轴承为后体结构,丝杠与阀芯为两体结构。本发明由于阀芯和丝杠分离,大大减小了电机拖动的转动惯量,当超载时,活塞杆不动,阀芯尽管有轴向移动,但由于它和丝杠是螺纹付联结,故避免了干涉破坏。同时由于丝杠采用了多头大螺距梯形或矩形螺纹,使得其承受负荷强度及导程加大,从而大大提高了脉冲油缸的速度。
英文摘要: The present invention relates to a high-speed hydraulic servo cylinder, consisting of piston rod, cylinder barrel, piston, nut, leading screw, bearing, fastening nut, valve body and valve core, and among them the nuts, piston and leading screw are anterior structure, and the valve body, valve core and bearing are posterior structure, and the leading screw and valve are double body structure. Because the valve core is separated from leading screw, the present invention greatly reduces the rotary inertia driven motor. When it is overloaded, the piston rod doesn't move although the valve core is axially moved, but because it and leading screw are threaded secondary connection, therefore the interference damage can be prevented. At the same time, because the leading screw uses multiple wide-pitch trapezoidal or rectangular thread, so that its load-bearing strength and lead can be increased thereby greatly raising impulse oil cylinder speed.
