摘　　要：大型往复式压缩机检修中,拆卸直径不同、重量不同的活塞需要不同的工作高度。根据拆卸过程中活塞的运动方向和受力特点,利用简捷的机械传动,通过螺旋传动副调节活塞托载平台高度,把活塞的运动轨迹变为可控。During the overhaul of a large reciprocating compressor, it is necessary to disassemble the pistons with different diameters and weights, which require different working heights.According to the movement direction and force characteristics of the piston in the disassembly process, a simple mechanical transmission is used to adjust the height of the piston-supporting platform through the screw transmission pair to make the movement trajectory of the piston controllable.

关 键 词：压缩机 抽取 回装 托载平台 螺旋驱动
