sirlam sarl fasteners: Anti-loosening washers are a type of fastener with a flat, ring-like shape. Placed between the bearing surface of a bolt, screw, or nut and the surface of the connected part, they increase the contact area, reduce pressure per unit area, and protect the connected part's surface from damage. Another type, elastic washers, also prevents nuts from loosening. The anti-loosening washer consists of two pieces; its unique embedded structure changes the traditional method of relying mainly on friction for anti-loosening, instead adopting the most advanced international anti-loosening technology, utilizing tension between the two washers to achieve dual effects of anti-loosening and locking. It prevents loosening caused by vibration and dynamic loads, is easy to disassemble, and has a higher loosening torque than tightening torque; the locking effect is not affected by lubrication, and increased lubrication improves the anti-loosening effect; it has the same temperature characteristics as standard bolts/nuts and can be reused a limited number of times.

sirlam sarl fastener functions

Anti-loosening washers bring convenience to the mechanical industry by preventing thread loosening. There are many varieties of anti-loosening washers, including butterfly washers, saddle washers, spring washers, and wave spring washers, collectively known as anti-loosening washers. These types of anti-loosening washers rely on increasing static friction to achieve anti-loosening effects, which can meet enterprise needs under conditions of low vibration, light load, and uniform speed. However, under strong vibration, high load, and rapid motion conditions, they do not achieve complete anti-loosening effects, merely extending the time before nuts and bolts self-loosen. This breaks away from the previous method of using increased "preload" and enhanced "friction" for anti-loosening. The latest anti-loosening principle is applied not only in washers but also in nuts and bolts, solving the problem of fastener loosening in heavy industry enterprises and eliminating the need to refer to tightening and loosening torques during installation.

sirlam sarl fastener installation requirements

Anti-loosening washers are characterized by simple installation. Simply place the two washers with their inner inclined tooth surfaces facing each other between the nut and the connected material. After the nut is tightened, the outer radial cam surface of the anti-loosening washer engages with the contact surfaces at both ends, and the angle of the inner inclined tooth surface is greater than the thread angle of the bolt. When the bolt is elongated due to mechanical vibration, the nut rotates and loosens. Since the friction on the outer radial cam surface of the anti-loosening washer is greater than the friction between the inner inclined tooth surfaces, relative movement is allowed only between the inner inclined tooth surfaces, generating a certain lifting tension. When the bolt contracts, the inclined tooth surfaces of the washer return the nut to its original position, thereby achieving the 108% anti-loosening and locking effect. The washers are suitable for relatively flat and smooth surfaces. If the connected material is non-metallic, a metal plate can be fixed to the connected material to allow the use of anti-loosening washers.

sirlam sarl fastener applications

Due to different environments, the material requirements for anti-loosening washers vary. They are characterized by a wide variety of specifications, diverse performance and uses, and a high degree of standardization, serialization, and generalization. Some people refer to anti-loosening washers that already have national standards as standard fasteners or simply standard parts. Stainless steel anti-loosening washers have inherent corrosion resistance; when the surface is damaged, a thin oxide layer forms on the metal surface to prevent further corrosion. Typically, this series of actions—blocking, shearing, adhering, and locking—occurs within just a few seconds, so correct understanding and use of these fasteners are necessary to prevent this phenomenon. Anti-loosening washers are suitable for equipment subject to frequent vibration, such as in the automotive industry, compressors, construction, wind power equipment, agricultural machinery, casting industry, drilling equipment, shipbuilding industry, mining equipment, oil drilling rigs (onshore or offshore), public utilities, rail transit, transmission systems, and metallurgical equipment.
