18.5.2 Knuckle Joint
This is a pin joint and is used to connect two circular rods subjected to axial loads. Compared to a
socket and spigot joint, wherein the axes of both the rods should be in the same plane; in the
knuckle joint, one of the rods can be swiveled through some angle about the connecting pin, i.e.,
the axes of the two rods could be inclined to each other.
Figure 18.40 shows the details of a knuckle joint. The eye end of the rod 2 is inserted into
the fork end 1 of the other rod. Then, pin 3 is inserted through the holes in the ends of the rods
and held in position by the collar 4 and taper pin 5. Figure 6.15 shows the assembly drawing.
