动作说明: 链节支架1绕固定轴A转动,其上装有可绕轴CC转动的滚子2。滚子2在D点与圆锥轮4接触,A为圆锥轮4的母线圆弧dd的圆心。圆锥轮4由键与轴3紧固联接,并绕固定轴BB转动。动力由轴CC输入。滚子与轴3的传动比为:
Action Description: The link bracket 1 rotates around a fixed axis A, on which a roller 2 rotatable around a shaft CC is mounted. Roller 2 contacts the conical wheel 4 at point D, and A is the center of the circular arc dd of the conical wheel 4. The conical wheel 4 is tightly connected with the shaft 3 by a key and rotates about a fixed axis BB. Power input from axis CC. Roller and shaft 3 transmission ratio:
