Comparative study of Crankshaft Thrust Washer Bearing Materials Under Different Conditions

Mechanical Engineering

Crankshaft thrust washers are generally made from aluminum base material and copper base material and form an important part of the main journal bearing that transmit and resolve axial forces in rotating mechanisms to keep components aligned along the shaft. Thrust washers are designed to prevent movement along the axis of a shaft. These rugged washer like flat bearings are used to prevent wheels from moving sideways on axles whenever the bearing that handles the radial load such as a bushing or roller bearing has no specific provision for axial and thrust loads. Thrust washers are a class of thrust bearings that use hydrodynamic lubrication action to support load. The lubricant film allows relative motion to occur between the surfaces while minimizing friction and wear. This paper will focus on wear rate under dry condition and lubricating condition for aluminum base material and copper Base Material.
