The invention discloses a linear transmission assembly and a lifting stand column. The linear transmission assembly comprises a transmission sleeve in transmission connection with a driving mechanism. The transmission sleeve is sleeved with the threaded pipe, external threads are arranged on the outer side wall of the threaded pipe, the threaded pipe and the transmission sleeve rotate synchronously, and the threaded pipe can slide in the axial direction of the transmission sleeve to generate displacement; a transmission nut is in threaded connection with the threaded pipe, and when circumferential rotation of the transmission nut is limited, the transmission nut can axially move relative to the threaded pipe to generate displacement; the fixing nut is coaxially connected to the threaded pipe, and the spiral direction of an internal thread of the fixing nut is opposite to the spiral direction of an external thread of the threaded pipe; and one end of the lead screw is arranged in the screw tube, and an external thread of the lead screw is spirally connected with an internal thread of the fixing nut. The linear transmission assembly is simple in structure, convenient to assemble and low in production cost.
本发明公开了一种线性传动总成及升降立柱,它包括与驱动机构传动连接的传动套管;套设在传动套管外的丝管,其外侧壁上设有外螺纹,所述的丝管与传动套管同步旋转且丝管可沿传动套管轴向滑动产生位移;所述的丝管上螺纹连接有传动螺母,且传动螺母周向旋转被限制时,传动螺母相对于丝管可轴向移动产生位移;固定螺母,同轴连接在丝管上,且固定螺母内螺纹的螺旋方向与丝管外螺纹的螺旋方向相反;丝杠,其一端设置在丝管内,且所述丝杠的外螺纹与固定螺母的内螺纹螺旋连接。该线性传动总成结构简单,组装方便且生产成本较低。
