连杆齿啮式减变速装置是一种连杆机构结合啮合传动组成的减变速装置。将连杆齿啮式减变速装置进行机构简化成为平面四杆机构,运用矩阵法进行运动学分析,得到连杆齿啮式减变速装置中偏心盘和连杆的位置、速度、加速度的运动学方程,应用MATLAB软件矩阵法编程得到连杆齿啮式减变速装置中偏心盘和连杆运动的角位移、角速度、角加速度和误差的变化情况,为该减变装置的结构优化提供了运动学基础。

Rod gear speed reducer and transmission is composed of linkage mechanism and meshing transmission. This transmission mechanism is simplified plane four-bar mechanism. On the basis of kinematics and geometry principle,the kinematics analysis of the mechanism is studied by means of matrix method. The corresponding kinematics equations are derived,including position,velocity and acceleration equations of rod and rockers. The computer simulation analysis is developed and the variation curve of main component angle displacement,angle velocity,angle acceleration and errors are figured by using MATLAB program language. This study laid a foundation for further analysis and optimization of the rod gear speed reducer and transmission.
