Kinematic link

kinematic link is defined as the part of the machine which has a relative motion with respect to some other part of the same machine is called kinematic link or element. Kinematic links can be divided into three types:

  1. Rigid link: in this type of link there is no deformation while transmitting the motion. The motion between the piston and the crank can be considered as a rigid link.
  2. Flexible link: in this type of link there is partial deformation while transmitting the motion. The belt drive is an example of a flexible link.
  3. Fluid link: in this type of link the motion is transmitted with the help of fluid pressure. The hydraulic brake is an example of a fluid link.
