双速行星传动的地面打磨机设计 摘要 当前，在地面上铺设瓷砖满足了人们追求美感的目的，可是，在地面铺设瓷砖却价格贵，这时，花费少且又不失美感的混凝土地面渐渐进入人们的视野，混凝土地面的需求日渐上升，也更能满足人们的需求，但是混凝土地面在铺设时会出现地面不平的现象，这时需要打磨机来对地面进行打磨，目前，人们使用的打磨机大多采用定轴或同步带传动，在此我想设计一款由行星传动的地面打磨机，因为行星齿轮传动与普通定轴齿轮传动相比较、具有质量孝体积孝传动比孝承载能力大以及传动平稳和传动效率高等优点。 首先针对地面打磨机进行总体方案设计，进而确定地面打磨机的总体布局，其次设计打磨机的传动过程，合理选择传动参数，进行计算，根据计算结果合理分配各级行星传动比，最后，得到合理的设计方案，此次设计提高了地面打磨机的工作效率。 关键词:行星传动地面打磨机轴齿轮 ABSTRACT At prese
