The role and classification of flat washers and elastic washers Industry Solutions

What is a flat gasket? What are the classifications of flat washers?

Flat washers refer to the parts that are padded between the connected parts and the nut. Generally, it is a flat metal ring used to protect the surface of the related parts from the nut abrasion, dispersing the pressure of the nut on the associated parts. Flat washers classification: flat washers - C grade, large flat washers - A and C grade, oversized washers - C grade, small washers - A grade, flat washers - A grade, flat washers - chamfered type - A grade, high strength washers for steel structure, spherical washers, taper washers, I-beam square beveled washers, channel steel with square beveled washers, standard spring washers, light spring washers, heavy-duty spring washers, internal tooth lock washers, internal serrated lock washers, External tooth lock washers, external serrated lock washers, single lug stop washers, double lug stop washers, external tongue stop washers, stop washers for round nuts.

What is the role of flat washers?

1. In screws with nuts, the role of the washer is to: increase the contact area, reduce pressure, protect the parts and screws.

2. Flat washers are made of aluminum, iron, stainless steel, spring steel, nylon, 65Mn or copper, etc. They can also be manufactured according to customer requirements and placed between the two planes to strengthen the sealing material and prevent fluid leakage between the sealing element's static sealing surface.

3. Flat washers are mechanical seals between two objects, usually used to prevent leakage between two objects subjected to pressure, corrosion, and the pipeline's natural thermal expansion and contraction. Since machined surfaces cannot be perfect, using washers can fill the irregularities.

4. Screws with nuts are usually fixed in through holes, the diameter of which is generally slightly more extensive than that of the screws, so washers are needed to increase the contact area. They are protecting parts. Lock the parts, reduce the pressure, protect the parts and screws.

5. Increase the contact area between the screw and the machine. Eliminate the damage to the machine surface caused by spring washers when removing screws. Spring washers and flat washers must be used: flat washers next to the machine's surface, spring washers in the flat washers, and nuts between them. The flat washer is to increase the force surface of the screw. Spring washers to prevent screws from loosening when the force plays a certain amount of buffer protection.

What is the role of spring washers?

Spring washers have the role of anti-slip and anti-loosening; spring washers are installed under the nut to prevent the nut from loosening. Spring washers for anti-loosening: flat washers have no relaxation function - flat washers increase the contact area; spring washers can be anti-loosening, such as motors and chassis connected to the bolts to generally add spring washers because the motor vibration if there are no spring washers, the nut will be loose.

1. The role of the spring washer is to tighten the nut and put an elastic force against the nut, so it is not easy to do all. The primary role of the spring is to pull the nut again after the nut to a force and increase the friction between the nut and bolt.

2. With spring washers, generally do not use flat washers (consider using flat washers and spring washers in addition to protecting the fasteners and the installation surface).

3. Flat washers are generally used to connect a soft texture or a hard brittle; their primary role is to increase the contact area and pressure dispersion to prevent the soft pressure's texture.

What does each of the large flat washers do? Flat washers, spring washers, large pad?

Flat washers are used to overcome unevenness in the workpiece support surface and increase the stress area of the support surface.

Spring (elastic) washers: spring washers rely on elasticity and beveled friction to prevent fasteners from loosening and are widely used in frequently disassembled connections. Oversized and flat washers have the same purpose, including the flat washers.
