The feeding scale of a traditional spiral lead screw feeding device such as an electric push rod, a mechanical arm and a turbine lead screw lifting machine is at most one time of the step length of the device. Sometimes, in order to be portable, to be convenient to unfold in a narrow working space or to reach an updated height, a spiral lead screw feeding device which is more flexible and convenient to use, larger than or equal to 1 in magnification ratio and larger in stretching scale is needed. The invention relates to an n-step spiral lead screw feeding device capable of outputting n step lengths, the moving distance of a lead screw can exceed the length of the lead screw in the device or even possibly approach n times of the length of the lead screw by rotating a nut meshed on the lead screw, and the device belongs to the field of mechanical transmission automation.
传统的电动推杆、机械手臂、涡轮丝杆升降机这类螺旋丝杆给进装置的给进尺度至多为该装置的一倍步长。有时为了便携、为了便于在一个狭小的工作空间里展开、或是为了企及一个更新的高度,这时我们需要一种使用更为灵便、伸缩比>>1、伸展尺度更大的螺旋丝杆给进装置。本发明涉及一种能够输出n个步长的n阶螺旋丝杆给进装置,通过转动啮合在丝杆上的螺母,就可使丝杆所移动的距离能超过该装置中丝杆自身的长度甚至可能接近丝杆长度的n倍,本装置属机械传动自动化领域。
