空压机十字头按十字头体与滑履的连接方式分为整体式与分开式两种。整体十字头虽然结构较轻巧,制造方便,但磨损后不能调正与机身导轨间的间隙,给机器修理带来了困难。近年来,我厂先后承修了几台2Z—3/8—1型无油润滑立式空压机,其十字头为铸铁制成的整体式,配用圆柱形浮动十字头销。几年来我们常遇到机身导轨烧伤以及伴随而来的整体十字头的修复问题,为此我们进行了一些探讨,取得了一定的效果。 Air compressor crosshead by crosshead body and slipper connection is divided into two types of integrated and split. Although the overall structure of the cross-head compact and lightweight, easy to manufacture, but can not be adjusted after wear and tear with the gap between the fuselage rails to machine repair has brought difficulties. In recent years, our factory has successively undertaken several sets of 2Z-3 / 8-1 oil-free vertical air compressors. The crosshead is made of cast iron and is equipped with a cylindrical floating cross pin. In recent years, we often encounter the fuselage rail burn and the accompanying problem of the overall crosshead repair, for which we conducted some discussion and achieved some results.
