cup washer的意思|示意

Cup washers are a type of fastener that is designed to spread the load of a threaded fastener, such as a bolt or screw, over a wider area. Cup washers provide an additional benefit in that they offer increased resistance to loosening under vibration or forces exerted in an axial direction.

Cup washers have a large outside diameter and a small inside diameter and are typically made from carbon steel or stainless steel but can also be found in a variety of other materials. The cup washer's outside diameter allows it to fit over the head of the fastener to spread the load of the fastener over a wider area and the inside diameter ensures a snug fit.

Cup washers are most commonly used when attaching a piece of equipment or a fixture to a surface. These washers help ensure that both the fastener and the surface are secured more strongly, reducing the risk of the fastener coming loose. Additionally, cup washers are often installed in machinery housing to reduce vibration and eliminate noise.

Cup washers are available in a variety of sizes to fit different fastener heads, making them a versatile and popular choice for many applications. When used correctly, cup washers can provide an effective and reliable way to secure fasteners in place.
