摘 要 摘要本次设计的是摆线针轮行星减速器摆线针轮行星传动具有传动比范围大体积小重量轻效率高运转平稳噪声低工作可靠寿命长的特点因此摆线针轮行星齿轮传动现已广泛地应用于工程机械矿山机械冶金机械起重运输机械轻工机械石油化工机械机床机器人汽车坦克火炮飞机轮船仪器和仪表等各个方面文中从对齿轮减速器的发展的历史研究开始再对传动比进行计算而后分别进行齿数计算齿形分析效率计算强度验算结构设计绘制减速器装配图及零件图最后对行星齿轮的结构设计进行了较详细的阐述通过对摆线针轮行星减速器的研究结合目前的发展情况和所要面临解决的问题设计出具有上述一系列优点的减速机构在设计中摆线针轮行星传动的薄弱环节是转臂轴承因转臂轴承在受力大转速也较高的情况下工作其内外圈的相对转速等于输入轴与输出轴二者转速绝对值之和所以 在新系列中为保证转臂轴承的寿命往往采用加强型的滚子轴承 关键词摆线针轮行星减速器齿轮行星齿轮减速器齿轮啮合滚子轴承 Abstract AbstractThis design is pin-cycloidal gear planetary Pin-cycloidal gear planetary gear transmission range is big small volume light weight high efficiency stable operationlow noiselong life and reliable Therefore the planetary gear transmission has been widely used in engineering machinery mining machinery metallurgy machinery lifting transportation machinery light industrial machinery petroleum chemical machinery machine tools robots automobile tanks artillery and aircraft ships instrument and meter etc Based on the development of gear reducer the study of history to start again then calculated the transmission separately gear tooth profile analysis and calculation the calculation efficiency strength calculation the structure design drawing assembly and detail drawings Finally the structure design of planetary gears are expounded in detail Through the cycloid planetary reducer combining the current development situation and to solve the problem the design has the advantages of a slowdown In the design of cycloid planetary gear the weak link is turning arm bearing because in turn arm bearing force high speed and under the condition of inner work the relative speed equals input shaft and the output shaft rotational sum between absolute so that a new series in turn for the life often arm bearing reinforced by the roller bearings Key words Pin-cycloidal gear planetary reducer gear planetary gear reducer gears meshing roller bearings 目录 摘 要 I Abstract II 第一章 绪论 1 11行星齿轮传动的发展概况 1 12 行星齿轮传动的发展趋势 3 13 行星齿轮传动的优缺点 4 14 本设计课题简介 6 第二章 摆线针
