Disc Spring Washers Standards and Uses Usage Industry Solutions

Is a disc washer and a disc spring washer the same thing? There is no difference between these two; disc washer is short for disc spring washer. It is a type of spring washer, as shown in the picture:

As you'll see from the picture, the disc spring washer is tapered on its own, and when tightened, it goes from tapered to flat, and the nut becomes less likely to come loose. The surface of the washer has serrated lines called ribs that reach into the tightened side, making it even less likely to come loose. Disc spring washers have a better anti-loosening and anti-vibration effect than other washers. Because disc spring washers have sound anti-loosening and anti-vibration effects, low manufacturing cost, easy to install, and other characteristics, more and more fields use butterfly spring washers, including automotive, electric power, construction, machine tools, aerospace and aviation, defense systems, medical equipment, and other industries.

Disc spring washers are standard industry solutions

Disc spring washers specifications: The main specifications are 36*71*4.0, 22.5*45*2.5, 14.2*28*1.5, 12.5*25*1.5, and so on. The material is generally 65MN spring steel.

The use of butterfly spring washers precautions industry solutions

Improper installation of butterfly spring washers will cause the nut to loosen; the correct installation direction should be the concave surface of the disc-shaped spring washers toward the connector and the convex surface toward the nut. After the nut is tightened, the disc spring washer will be deformed by force, and the supporting surface will be reactive, locking, and anti-loosening. Butterfly spring washers have a lot of sharp elastic teeth on the circumference of the warped teeth, stabbing pressure on the bearing surface, can prevent the fastener from loosening. The inner teeth of the flexible washer for the head size of the smaller screw head; the outer teeth of the loose washer for the bolt head and nuts under the loose washer. Adjustable washers with teeth smaller than ordinary spring washers and fasteners with uniform force to prevent loosening are reliable but should not be used for frequent disassembly.
