Railway washers are mainly used to prevent bolts from loosening. They ensure the stability of components through a locking structure and also achieve the function of conducting electricity for grounding. The specific functions are as follows:
Anti-loosening locking
The washer is designed with a combination of radial raised surfaces and inclined tooth surfaces. When the bolt is subjected to vibration and shows a tendency to loosen, the inner inclined tooth surfaces will generate an upward tension through relative displacement, achieving a 100% locking effect and effectively preventing bolts from accidentally loosening in railway transportation equipment.
Grounding and conductive
The tooth design of the washer can pierce the insulation layer, enhancing the electrical connection between metal components and ensuring the reliability of grounding in scenarios such as electrical cabinet assembly, avoiding potential safety hazards caused by poor insulation.
Buffer and vibration reduction
Some railway washers (such as those made of rubber) can also play a buffering role during train operation, reducing the impact force between the rail and the sleeper, protecting the roadbed structure and improving the smoothness of train operation.
