1、摘摘 要要 加载器是齿轮箱在以封闭试验台形式进行试验的常用加载工具， 本文首先介绍了加 载器的特点、分类以、国内外发展的现状以及所存在的缺点等等。通过对现有加载器的 分析研究和对设计要求的分析，同时为了有效避免现有的加载器存在的各种不足，对加 载装置进行了整体结构设计，提供一种比较理想的加载装置，研究并设计出一种新型转 矩可调式内斜齿液压加载装置，并对加载装置各关键部件进行了受力分析和强度校核， 该加载装置通过采用一对基本参数相同， 旋向相反的内斜齿圆柱齿轮使得加载机构的结 构紧凑，能够双向加载；采用合理的结构设计提高了传动零件的支撑刚度，并通过设置 多处密封圈，很好地改善了液压加载装置的密封
2、问题，通过受力分析得到齿轮所受的轴 向力大小，能够实现加载可靠、精度高、载荷便于测量，能够在长期运转中保持加载力 矩稳定不变；能够实现空载起动，并能在运转中改变加载力矩的大小，便于进行模拟实 验；整体方案结构简单，便于制造、装配、调整和操作。 关键关键词词：加载装置 结构设计 强度校核 ABSTRACT The loader is a common load tool which is used in gearbox.
