行星爪卡紧机构的设计与计算

本文介绍了行星爪卡紧机构的特点和工作原理。通过对卡紧机构的受力分析,提出了用控制切径比m的大小来控制对圆柱体的卡紧握度。通过对卡紧机构的受力计算,推导出行星爪外曲面形牙板轮廓曲级的坐标值计算式,从而确定行星爪零件及牙板的几何尺寸,并编改了微机计算程序及框图。

Design and Calculation of Planetary Grip Mechanism

The paper depicts the design features and working prin--ciples of planetary grip mechanism and. on the basis of loadanalysis of the grip mechanism, shows that the grippingforce on a cylindric surface can be controlled by adjustingthe value of tangential--force--to--radial--force ratiom. Auequation for calculating the coordinate values of the contourcurve of the positive cambered dies on the planetary claw isderived, thereby the geometric dimensions of the claw partsand dies can be determined. And a minicomputer programwith flow chart is introduced for reference.
