自动搓背机器人的新型内摆线机构设计
摘要
摆线针轮行星传动于1922年由德国学者卢布林卡提出。由于这种传动具有结构紧凑、单级传动比大、工作平稳、噪音甚低、承载能力和效率高等一系列有点。在许多情况下,它可以代替二级、三级普通齿轮搓背机和蜗轮蜗杆搓背机。
本设计针对便于制造、装配和检修方面，设计了具有合理结构的摆线针轮行星搓背机。并对其主要件的强度进行了计算并校核及对转臂轴承、各支承轴承的寿命进行计算，从分析结果可以看到，各轴承性能指标均符合要求。
利用solidworks软件对摆线针轮搓背机主要零件建立几何三维模型、利用Auto CAD软件生成摆线针轮搓背机的工程图。用本文的方法设计摆线针轮搓背机，具有设计快捷、方便等特点。研究结果对于提高设计的速度、质量具都有重要意义。

Design of put forward bythe German scholar Ruble Cycloidal drives
Abstract：Cycloidal drives has been put forward bythe German scholar Ruble Linka in 1922.In manycases,it can substitute for secondaryand tertiarygeneral gear reducer andworm gear reducer because it has the compact structure,large single-stage transmission ratio,stableworking,lownoise,and high efficiencyand carrying capacity.Thus,it iswidelyused in machinerymanufacturing,petrochemical industry,hoisting and conveying machinery,geological drilling and so on.
In this design,the author designs a cycloid pin gear planetaryreducerwith reasonable structure to facilitate the manufacturing,assemblyand maintenance.And the strength of the main parts have been calculated and checked,and the life of tumbler bearing and back-up bearing also has been calculated.And from the analysis of the result,it is obviouslythat all the bearing performance indexes meet the requirements.
This design makes use of the Pro/e software to establish a three-dimensional geometric model about the main parts of cycloidal pinwheel reducer,and makes use of the Auto CAD software to assemble of cycloidal pinwheel reducer invirtual and generate the engineering drawings.Cycloidal pinwheel reducer,which is designed byusing the method of this paper,has manycharacteristics,such as design fast and convenient.The results of the studyhave great significance to improve the speed and qualityof design.
