摘　　要：气缸安装余隙是保证压缩机正常运行的重要参数.船舶在波浪中航行时所产生的总体弯曲变形不可避免地会影响沿船体纵向布置的卧式压缩机气缸运行余隙.为了确保船舶在波浪中航行时卧式压缩机气缸运行余隙始终能维持在合适范围内,本研究将船舶总体弯曲时的结构弹性变形等关键因素直接溶入船用卧式压缩机气缸安装余隙的传统计算,从而导出一项能确定船用卧式压缩机气缸安装余隙最小值的新计算公式.The cylinder assembly clearance is an important parameter for ensuring compressors to operate normally. For a marine horizontal compressor arranged along the ship longitudinal direction, the longitudinal bending deformation generated during the ship navigating on the waves will inevitably affect the cylinder running clearance of the horizontal compressor. In order to ensure that the cylinder running clearance of a marine horizontal compressor always keeps within the reasonable range during the ship navigating on the waves, the authors of this article include such key factors as the ship structure elastic deformation directly into the traditional calculation of the assembling clearance of horizontal compressors, and derive a new formula capable of determining correctly the assembling clearance of marine horizontal compressors.
