Structure and Composition
The heavy spring washer is fabricated from resilient spring steel. It has a coiled or undulating form. The dimensions, both in terms of thickness and overall diameter, are precisely engineered to integrate seamlessly into the rail fastening mechanism. This distinct configuration endows it with a notable degree of flexibility.
Functions
- Preventing loosening: A key function is to act as a safeguard against the loosening of nuts and bolts within the rail fastening assembly. Due to the inherent springiness, it exerts a persistent compressive force, which is crucial for maintaining the tightness of the bolted joint. For instance, when trains pass by, the heavy spring washer effectively counteracts the forces that might otherwise cause the fasteners to loosen over time.
- Load spreading: Additionally, it serves to evenly disperse the load across the surfaces being fastened. This mitigates the risk of stress concentration at particular points and minimizes the potential damage to the rail or other components. This is of great significance in the railway environment where heavy loads are continuously imposed.
Benefits
The durability and dependability of the heavy spring washer make it well – suited for the rigorous operating conditions of railways. It can endure exposure to various weather conditions, high – impact forces, and persistent vibrations. By ensuring the security of the fasteners over an extended period, it makes a substantial contribution to the overall safety and stability of the railway track system.
