Kinematic model: four-joint link (KI 130)

Kinematic model: four-joint link (KI 130)

conversion of rotary motion into oscillating motion

Code Kl130

Description:

  • The four-joint link is a four-bar pivot gear.
  • It converts rotary motion into oscillating motion.
  • The KI 130unit 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.
  • The input angle is adjusted using the drive disk, and an angle scale is integrated into the base plate.
  • The output angle is read at the angle scale on the output disk.
  • The elements are mounted on a base plate.
  • Two handles make it easy to carry and stack the unit.
