SUMMARY

The discussion focuses on designing a mechanism for the synchronous rotation of two half circles using springs and a single input rotational source. The user proposes using a crank and slider mechanism, with a link from the slider to both circles to achieve the desired opening and closing motion. Key considerations include the functionality of the mechanism and the need for the half circles to move as mirror images about a plane. The user seeks guidance on the effective use of springs in this design.

PREREQUISITES
  • Understanding of mechanical design principles
  • Familiarity with crank and slider mechanisms
  • Knowledge of spring mechanics and their applications
  • Basic concepts of rotational motion and synchronization
NEXT STEPS
  • Research the principles of spring mechanics in mechanical systems
  • Explore detailed designs of crank and slider mechanisms
  • Investigate methods for achieving synchronous motion in mechanical linkages
  • Study the effects of mirror image motion in mechanical designs
USEFUL FOR

Mechanical engineers, product designers, and hobbyists interested in creating synchronized mechanical systems and exploring innovative design solutions for rotational mechanisms.

Regards Respected Teachers and Members

I would like to draw a mechanism that two half circles should rotate synchronous close and open as a result gears will rotate at same Value , i would like to use springs in this mechanism between circles , the other idea i know that use crank and slider , link from slider attached to both circles as a result opening and closing will happen , but i would like to use springs and the input rotational source should be one as shown in figure

Need guidance about spring using

Thank you

I think we need to step back and look at why the mechanism needs to move the two quadrants or part circles. What will the quadrants be doing ?

Do the part circles move as mirror images about some plane ?
