Presenting a comprehensive overview of our innovative double-layered self-locking washer, engineered for unmatched stability:
Structural Design: Meticulously crafted with two interlocking metal washers, each boasting a wedge-shaped or cam-shaped large tooth surface on one side, and radial fine teeth on the opposite. The strategic alignment of the large tooth surfaces, positioned opposite each other, allows for seamless pair assembly and use.
Working Principle: As the bolt or nut is tightened, the radial fine teeth enhance the friction coefficient of the contact surface, ensuring steadfast grip. In the event of bolt loosening, slip occurs between the wedge-shaped teeth. The brilliance of this design lies in the wedge-shaped teeth angle, which surpasses the thread lift angle, thereby thickening the washer axially more than the thread's axial climb. This ingenious mechanism boosts the axial preload of the bolt, safeguarding against loosening triggered by vibrations.
Material Characteristics: Constructed from premium materials including stainless steel, carbon steel, and others like EN1.4404 alloy steel for stainless steel, EN1.7182 alloy steel for carbon steel gaskets, S60c, and 35CrMo high-grade special steel. These selections ensure superior high-temperature resistance, moisture resistance, and exceptional corrosion resistance, catering to a variety of demanding environments.
Product Advantages: Delivering unparalleled safety, these washers effectively counteract loosening due to vibrations and dynamic loads. The locking efficiency remains unaltered by lubrication, providing a consistent locking effect regardless of pre-tightening force. Designed for reusability, they exhibit identical temperature characteristics as standard bolts/nuts whilst allowing precise control over pre-tightening force.
Application Areas: These versatile washers find extensive applications across diverse industries such as automotive, 3C, equipment manufacturing, medical, aviation, and rail. They serve as critical fastening components for aircraft engines and fuselage structures, automotive chassis, engines, and other vital parts. Additionally, they play a pivotal role in the connection and fastening of heavy machinery and electrical equipment, not to mention their utilization in the construction of bridges and ships.
