| A Crank and Slider mechanism / linkage, takes rotary motion and coverts it to linear motion. The diagram (below), shows how a piston pushes and pulls the connecting rod, which rotates the crank. This is typical of steam engines. This mechanism is vital in combustion engines and has many other practical applications such as; pumps and compressors, machinery and even robotics. |
|
|
This mechanism is composed of three important parts: The crank which is the rotating disc, the slider which slides inside the tube and the connecting rod which joins the parts together. |
|
 |
|
|
As the slider moves to the right the connecting rod pushes the wheel round for the first 180 degrees of wheel rotation. When the slider begins to move back into the tube, the connecting rod pulls the wheel round to complete the rotation. |
