Four Joint Link Kinematic Model
The Four-Joint Link is a four-bar pivot gear. It converts rotary motion into oscillating motion.
The unit can be used to investigate the crank-rocker mechanism, the double rocker mechanism and the double crank.
The experimental unit comprises the drive disk with the crank and coupling and the output disk with the rocker. The elements are connected to each other via pivot joints. The positions of the pivot joints can be varied to adjust the crank radius, oscillation radius and coupling length. The drive disk can be driven by the crank.
Learning Objectives And Experiments
- Investigation of the mechanical relationships on the four-joint link
- Investigation of the principle of the crank-rocker mechanism, double rocker mechanism and double crank
- Verification of the condition by varying the crank radius, oscillation radius and coupling length
- Conversion of rotary motion into oscillating motion
