The invention relates to the technical field of lead screw lifters, discloses a lead screw lifter and solves the problem that lubricating oil cannot be fully utilized due to the fact that multiple dead corners exist in flowing of the lubricating oil in a conventional lead screw lifter. The annular mounting seat drives the inclined clamping ring and the fluctuating annular plate to rotate, so that the arc-shaped piston sleeve is driven by the annular mounting seat and the edge of the arc-shaped piston sleeve to do circulating fluctuating lifting motion, the arc-shaped piston sleeve is matched with the extrusion channel, lubricating liquid in the upper cavity is pumped into the middle cavity, the lubricating liquid in the middle cavity is pumped into the lower cavity, and the flowing effect is formed. And dead angles caused by flowing of lubricating oil are avoided, so that the lubricating oil is fully utilized.
本发明涉及丝杆升降机技术领域,公开了一种丝杆升降机,解决了常规丝杆升降机内,润滑油在内部的流动存在多处死角,使得润滑油得不到充分利用的问题,通过利用蜗杆本体带动涡轮本体的转动,同步带动一体形成的环形安装座转动,环形安装座带动倾斜的卡环、起伏环状板转动,使得弧形活塞套管随其带动,边缘做循环起伏升降运动,弧形活塞套管配合挤压通道,分别的将上腔体的润滑液泵入中腔体内,以及将中腔体的润滑液泵入下腔体内,形成流动效果,避免润滑油流动存在死角,使得润滑油得到充分利用的效果。
