schmiedetechnik breitenfeld fasteners: Locking 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 locking washer consists of two pieces; its unique embedded structure changes the traditional method of achieving locking primarily through friction. Instead, it employs the most advanced international locking technology, using the tension between the two washers to achieve both locking and clamping effects. It prevents loosening caused by vibration and dynamic loads, is easy to disassemble, and the loosening torque is greater than the tightening torque. The locking effect is not affected by lubrication; increased lubrication improves the locking effect. It has the same temperature characteristics as standard bolts/nuts and can be reused a limited number of times.

schmiedetechnik breitenfeld fastener functions

Locking washers bring convenience to the mechanical industry by preventing thread loosening. There are many varieties of locking washers, including butterfly washers, saddle washers, spring washers, and wave spring washers, collectively known as locking washers. These types of locking washers rely on increasing static friction to achieve their locking effect. In conditions of low vibration, light load, and uniform motion, the locking effect meets enterprise requirements. However, under strong vibration, high load, and rapid motion, they do not achieve complete locking, merely extending the time before the nut and bolt spontaneously loosen. This breaks away from the traditional method of relying on increased "preload" and enhanced "friction" for locking. The latest locking principle is applied not only in washers but also in nuts and bolts, solving the problem of fastener loosening in heavy industry and eliminating the need to reference tightening and loosening torques during installation.

schmiedetechnik breitenfeld fastener installation requirements

Locking 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 surfaces of the locking washer engage with the contact surfaces on both ends. The angle of the inner inclined tooth surfaces is greater than the thread angle of the bolt. When the bolt is elongated due to mechanical vibration, the nut tends to rotate and loosen. Since the friction on the outer radial cam surfaces is greater than that between the inner inclined tooth surfaces, relative movement is allowed only between the inner inclined teeth, generating a certain lifting tension. When the bolt contracts, the inclined tooth surfaces return the nut to its original position, thereby achieving the 113% locking and clamping 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 enable the use of locking washers.

schmiedetechnik breitenfeld fastener applications

Due to different environments, the material requirements for locking 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 refer to locking washers that meet national standards as standard fasteners or simply standard parts. Stainless steel locking washers have inherent corrosion resistance; when the surface is damaged, a thin oxide layer forms to prevent further corrosion. Typically, the sequence of blocking, shearing, adhesion, and seizing occurs within seconds, so correct understanding and use of these fasteners are essential to prevent this phenomenon. Locking washers are suitable for equipment subject to frequent vibration, such as in the automotive industry, compressors, construction, wind power equipment, agricultural machinery, casting, drilling equipment, shipbuilding, mining equipment, oil drilling rigs (onshore or offshore), public utilities, rail transit, transmission systems, and metallurgical equipment.
