摘要
从几何学与运动学角度对行星弧面凸轮减速机构进行了分析与研究,根据空间机构的共轭啮合原理,采用齐次坐标变换推导了减速机构内弧面凸轮的轮廓曲面方程和压力角方程,并对机构的基本尺寸或参数选取进行了探讨,发现在满足滚子抗弯强度的前提下,采用具有较多滚子的从动盘有助于降低传动压力角和提高传动效率.行星弧面凸轮减速机构通过滚子与凸轮廓面的滚动摩擦代替传统减速机构的滑动摩擦,并且同时参与啮合传动的滚子数多,具有传动效率高、传动扭矩大等优点.
The characteristic of planet globoidal cams reducer mechanisms was analyzed and studied from the angles of geometry and kinematics. Based on matrix transformation and conjugation engagement theory of spatial mechanisms, the surface equation and pressure angle equation of inner globoidal cams were attained. Moreover, the basic parameters of planet globoidal cams reducer mechanisms were discussed. It was found out that using driven plate with more milers could help reduce transmission pressure angle and could increase transmission effidency. Planet globoidal cams reducer mechanisms possessed some advantages, such as higher transmission efficiency and higher transmission torque, over traditional reducer through repladng sliding friction with rolling friction and having more miler working at the same time.
