Getting to know the types of washers

A simple washer is a flat disk and has a hole in its center A screw or stud can pass through it. Using it, the surface under the bolts is smoothed. In this way, the nut pressure is uniform over the entire surface. A simple washer is used to distribute the load over a relatively larger area. Thus, it prevents damage to the assembled surfaces. The following types of simple washers are available in the market.

Simple flat washers are thin, smooth and circular in shape with a hole in the center. .

Using simple flat washer to create load It is in a relatively large area and supports small head screws.

also called A-type simple washers.

A flat washer is what most people think of as a normal washer and is fine for normal use.

This type of gasket is used to insulate wires, screws or any other part of the assembly. This type of washer is made of glass, phenolic, nylon and metal fibers.

C washer looks like a flat washer, with the difference that a gap is cut from the middle hole to create a "C" shape. A C-shaped washer is made to fit in and out of place on the bolt and shaft and Without the need to remove the fastener, it is possible to adjust or replace the washer C.

They are also called finish washers because of their finished assembly appearance. Watertight washers have a counter that holds the fastener head. This type of gasket provides surface protection of the gasket and is available in various forms. Including: Floating 90 degrees Angular float flange without flange Rolled flange

The spring washer is in the form of a ring that is cut by the spring steel. Its end goes up and down a little due to the tension of the spring. These washers are placed at the top or bottom of the nut or screw and are tightened so that Both ends of them are placed towards each other and aligned.

The Belleville washer consists of two sides that It supports very heavy force with small deviations. It is also known as conical washer.

Domed spring washers are similar to Belleville washers but with rounded sides. Domed spring washers produce a very high load capacity with a relatively small range of deflection. They form ground curves to have a higher load bearing surface. Wherever the domed washer is used, it creates a smoother surface.

These types of washers rotate in two directions and create a wave-like shape. Curved spring washers have sufficient load capacity and deflection. They work as cushion springs or spacers on the shaft. Curved spring washers have a moderate load capacity and deflection limit. Most of the time it is used as a cushion or spacer.

The finger spring washer consists of three curved flanges. Finger spring washers are used to reduce the following: Damping and sound Extra wear shaking Wear of rotating parts The finger spring washer is made of carbon steel. They combine the flexibility of cover washers with the load points of wave washers.

This form of lock washer is used to lock nuts and bolts. This type of washer has different shapes, generally extending six leaves or more from the main diameter of the lock washer. After repairing this washer, its leaves are bent on the sides of the nut or screw. Therefore, this washer prevents the nut ribs from loosening. This washer is generally used in cars, trucks, etc.

Split lock washers are non-continuous rings that Each of their ends is slightly bent in the opposite direction. When the gap lock washer is tightened, each end is drilled into the mating surfaces. It is also sometimes known as a spiral washer.

This type of lock washer consists of a large number of teeth in the inner diameter that become nuts or bolts. The inner tooth lock washer prevents loosening of the fastener head by using the action of the tooth protrusion. This type of washer can also absorb shock and vibration. It is used to lock the shallow head joints.

This type of lock washer has many teeth on its outer diameter It is cut and maintains compression. The external tooth lock washer prevents the loosening of the connector head by using the action of the tooth protrusion. External tooth lock washer provides maximum torsional resistance. Used to lock deep head fasteners in place.
