Kinematic model: Hooke's coupling (KI 150)

Kinematic model: Hooke's coupling (KI 150)

investigation of a universal joint shaft

CodeKl150

Description:

  • Universal joint shafts are joint shafts that transfer a torque and a rotational motion.
  • A universal joint combines two non-aligned shafts.
  • In a universal joint, the torque and the speed are non-uniformly transmitted.
  • This non-uniform transmission is called the gimbal error.
  • This is remedied by using two universal joints connected to each other by an intermediate shaft.
  • This combination is referred to as the cardan shaft or the universal joint shaft.
  • The KI 150unit can be used to study a universal joint shaft.
  • A universal joint is also known as Hooke’s coupling.
  • The experimental unit comprises two universal joints with intermediate shafts.
  • The arrangement of the universal joints and the deflection angle can be set using two rotary disks on the base plate.
  • On the drive side, the input angle is set and read by the drive universal joint.
  • The intermediate shaft transmits the torque to the driven universal joint.
  • The output rotation angle is read.
  • The gimbal error is determined from the difference between the two angles.
  • The elements are mounted on a base plate.
  • Two handles make it easy to carry the unit.
