Conical cam mechanism has been widely used in modern machinery and ***,the commonly used planar expansion methods for the design of spatial cam contour produce significant errors,because these methods incorrectly use the distance from the axis of the follower to the main conical cam to replace the corresponding arc length on the conical ***,et al,used analytical methods to achieve higher accuracy,but these analytical methods have their own drawbacks since they are too complicated for practical *** the analysis of the errors created during the generation of conical cam contour using the existing expansion methods,this paper proposes to include diverge angle in the calculation of conical cam rotation angle in the equation of conical cam contour *** correction eliminates the error generated by the commonly used *** on the expression of the follower＇s 3D trajectory and the spatial geometry of conical cam,this paper has deduced the planar polar curve equation for determining polar coordinates for the curve of planar expansion ***,this paper provides an example of conical cam contour design based on sinusoidal acceleration *** to polar coordinates and the movement of curve equation function expression,this paper applies MATLAB software to solve coordinates for the cam expansion curve and uses AutoCAD software to generate conical cam expansion contour that meets the requirement of the law of *** proposed method provides a design process that is simple,intuitive and easy to master and *** also avoids the design error in the traditional methods for generating contour of conical cam with oscillating follower that requires high precision.
