二级圆锥-圆柱齿轮减速器
摘要
减速器是各类机械设备中广泛应用的传动装置。减速器设计的优劣直接影响机械设备的传动性能。
减速器是原动机和工作机之间的独立的闭式传动装置，用来降低转速和增大转矩，以满足工作需要，在某些场合也用来增速，称为增速器。
选用减速器时应根据工作机的选用条件，技术参数，动力机的性能，经济性等因素，比较不同类型、品种减速器的外廓尺寸，传动效率，承载能力，质量，价格等，选择最适合的减速器。
减速器的类别、品种、型式很多，目前已制定为行（国）标的减速器有40余种。减速器的类别是根据所采用的齿轮齿形、齿廓曲线划分；减速器的品种是根据使用的需要而设计的不同结构的减速器；减速器的型式是在基本结构的基础上根据齿面硬度、传动级数、出轴型式、装配型式、安装型式、联接型式等因素而设计的不同特性的减速器。
与减速器联接的工作机载荷状态比较复杂，对减速器的影响很大，是减速器选用及计算的重要因素，减速器的载荷状态即工作机（从动机）的载荷状态，通常分为三类：
①—均匀载荷; ②—中等冲击载荷; ③—强冲击载荷。
本文主要二级圆锥-圆柱齿轮减速器的设计，设计中存在不足
的请大家给予意见和建议。
