  虽如今工业水平先进，机械化程度逐步的提升，起重设备一直更新，但仍不能淘汰卷扬机这行之有效的机械设备。本人所研究的是JM建筑卷扬机。JM系列属慢速卷扬机。在本设计中主要对卷扬机传动部分、工作机构及卷扬机的主体部分进行设计。在传动部分采用的是二级齿轮减速器和开式齿轮传动，工作部分的卷筒采用的是焊接式卷筒。该卷扬机的主要特征是结构相对比较简单，操作方便。

  建筑卷扬机由于应用场景范围较广，为源自文库应各种不同的使用条件，建筑卷扬机亦制造成各种不同机型的产品。机型的分类很多，目前可以按下述方法分类。

  按钢丝绳在基准层上所能承受的最大拉力来区分。按GB1955—88《建筑卷扬机》中规定为5、7.5、10、12.5、16、20、25、32、50、80、120、160、200、320、500KN共15级。此参数为建筑卷扬机的主要参数。

  建筑卷扬机是一种起重设备，由于具有结构相对比较简单、搬运安装灵活、维护保养简单、操作便捷、价格低和可靠性高等优点，所以被大范围的应用于提升重物、打桩、集材、冷拉钢筋、设施安装等工作中。

  提升重物是建筑卷扬机的一种基本功能，所以各类卷扬机是根据这一要求为依据的。虽然现在塔吊，汽车吊取代了建筑卷扬机的工作。如塔吊在建筑施工工地上用于物料和物件的提升工作。由于塔吊成本高一般在大型建筑中使用，而且灵活性较差，也需卷扬机做辅助提升用。建筑卷扬机还用于林业的集材工作。建筑业的冷拉钢筋，小型矿井的物料提升和打桩等工作。正因为建筑卷扬机具有多种用途，所以不仅用于建筑业，而且在冶金，化工，水电，农业和军事等行业亦被广泛使用。

  6.2减速箱各部分附属零件设计·····································37

  6.3制动器联轴器的选择···········································38

  1.2.2按钢丝绳额定速度 分········································1

  1.2.3按卷筒数目分···············································1

  1.2.4按动力源分·················································2

  此机器的基本功能：在建筑业的冷拉钢筋提升重物，在林业的集材工作，同时在水电、农业等行业均能被采用。

  该类机器的发展的新趋势应该向大型化、使用先进电子控制、手提式卷扬机、不带电源装置的卷扬机的方向发展。
