Design Of Lock Washers Of Metal

A lock washer is a type of washer that is designed to prevent fastening or loosening of mechanical parts. It is usually made of metal and comes in various shapes, including split, helical, and toothed. The working principle of a lock washer is based on friction between the washer and the fastener, which increases the resistance to the loosening of the assembly. Lock washers are commonly used in automotive, aerospace, and heavy machinery industries, where vibration and shock loads could cause a fastener to become loose. Designing a good lock washer requires careful consideration of several factors. Firstly, the geometry of the washer should be chosen based on the application requirements. Split washers are suitable for low load applications, while toothed washers are ideal for high load applications. Secondly, the material of the washer should be chosen based on the corrosion resistance and strength required for the application. Stainless steel and brass are commonly used materials for lock washers due to their excellent corrosion resistance. Thirdly, the thickness and hardness of the washer are critical factors that determine the locking force. A thicker washer will provide a higher locking force, but it will also require a larger space to fit in. Finally, the surface finish of the washer should be smooth to ensure proper torque transfer between the washer and the fastener. In summary, a good lock washer is one that is designed to fit the application requirements in terms of geometry, material, thickness, and surface finish. It should effectively prevent fastening or loosening of mechanical parts even under high vibration and shock loads.
