- A cotter is a flat wedge-shaped piece of steel.
- This is used to connect rigidly two rods that transmit motion in the axial direction, without rotation.
- These joints may be subjected to tensile or compressive forces along the axes of the rods.
- Examples of cotter joint connections are the connection of piston rod to the crosshead of a steam engine, valve rod, and its stem, etc.
Additional Information
- Knuckle joint is a type of mechanical joint used in structures, to connect two intersecting cylindrical rods, whose axes lie on the same plane. It permits some angular movement between the cylindrical rods (in their plane).
- It is specially designed to withstand tensile loads. It facilitates rotation about the axis but arrests displacement.
