Various Mechanisms 2

1) Scotch Yoke Mechanism

This type of mechanism gives horizontal action as a result of rotational input. This mechanism is nearly similar to the crank and piston arrangement.

2) Crank and slotted lever Mechanism

Speed of horizontal movement is the differnce between this and previous mechanism. The speed of forward movement is faster than the backward movement.

3) Whitworth Quick Return Mechanism

This type of mechanism is quite similar to the crank and slotted lever mechanism.

4) Oldham Coupling

This type of coupling is used to transmit the torque from one shaft to the other shaft which is parallel to each other.

5) Hook's Joint

This Mechanism used to transmit power from different height variation. It is otherwise called as Universal joint.
