对数螺旋凸轮机构的设计和研究

Design and Research of Logarithmic Spiral Cam

将平面对数螺旋线引入凸轮外缘轮廓,结合对数螺旋线特点和凸轮功能,从理论上论证了平面对数螺旋凸轮可行性。设想用2条对数螺旋线构成凸轮轮廓,结合圆弧构成封闭曲线。进而分析对数螺旋凸轮的参数选定,依据参数修正对数螺旋轮廓曲线。确定合适的对数螺旋凸轮方程。

This article introduces the planar logarithmic spiral as the outer edge of the cam profile, combined with the logarithmic spiral cam features and functionality, demonstrated the feasibility of planar logarithmic spiral cam in theory and conceived two logarithmic spiral form into the cam profile, combined with the arc form a closed curve. And then analyzes the parameters being right selected of the logarithmic spiral cam , Amend the logarithmic spiral profile curve based on the parameters which have been selected. Determine the appropriate equation for the logarithmic spiral cam.
