TRUNNION Meaning and
Definition
-
A trunnion is a cylindrical projection on a device that serves as a pivot or point of support. It typically takes the form of a metal rod or shaft that protrudes horizontally from a structure or machine. Trunnions are commonly used in various applications where rotational movement is required.
In mechanical engineering, trunnions are often found in machinery that requires a swinging or oscillating motion, such as machine tools, valves, or certain types of guns. They act as the primary support for the rotating component, allowing it to pivot smoothly and securely.
Trunnions are typically designed to handle heavy loads and provide stability in rotating systems. They are often incorporated into a bearing assembly, ensuring proper alignment and reducing friction and wear. Lubrication is often applied to trunnions to minimize friction and prevent premature failure.
In the field of artillery, a trunnion refers to the cylindrical projections on the sides of a cannon or gun carriage. These trunnions enable the weapon to be mounted on a carriage, allowing for elevation and azimuth movements. By adjusting the elevation angle, the gun's range can be modified.
Overall, trunnions serve as crucial components in various devices, facilitating rotational movement and ensuring stability and control. Through their design and placement, they play a vital role in achieving accuracy, smooth operation, and efficient functionality, making them essential elements in many mechanical and weapon systems.

Etymology of TRUNNION
The word "trunnion" is derived from the Old French word "tronon", meaning "stump" or "cut-off piece". It entered the English language in the 17th century and originally referred to the pivoting or supporting pins used in cannons, mortars, and other artillery devices. Over time, the term expanded to include similar pivot points in various mechanical and engineering applications.
