旋耕机传动部分设计 摘要 旋耕机是由拖拉机作为动力且由它拖动的一种代替人工的耕地机械。这种机械可以很好地完成翻新土地，切断根茎等工作，所以在农业生产者中受到好评；这样的耕地方式有利于后面播种机作业，为播种提供良好土壤环境。农业需求在不断提高，所以旋耕机的创新仍然具有重要意义。目前发现的突破点主要有大功率旋耕机的研究尚有空间、作业性能无法满足当今社会需求、旋耕机轴部件设计及材料使用等。 本文设计了侧边传动式旋耕机，根据工作要求，确定了旋耕机的动力机械、传动装置、工作部件以及耕深调节装置。传动装置包括齿轮箱、侧边传动箱、传动轴等。分别对各部分主要零部件进行了设计与校核，包括齿轮，轴，轴承。其中齿轮箱和侧边传动箱是本次设计的重点。 通过本次设计，会得出一款简易又可用的旋耕机，主要设计部分还是旋耕机的传动部分，在设计过程中，会加深对所学知识的巩固，能让理论用于实际。 关键词：旋耕机传动部分；齿轮箱；侧边传动箱 Desig
