| The outer tongue stop washer, through its special design and structure, can effectively fix the axial position and prevent mechanical components from moving or loosening in the axial direction, which is crucial for maintaining the stability and reliability of the mechanical system. In mechanical transmission systems, the connections between components often need to withstand various forces and torques. The outer tongue stop washer can provide additional support and stability, ensuring that the connecting components do not change direction when subjected to force. By increasing friction, the outer tongue stop washer can effectively prevent screws or bolts from loosening under vibration or force. This increased friction ensures the stability of the connection and reduces the possibility of loosening.. The outer tongue stop washer can distribute the load on the screw or bolt to a larger surface, thereby reducing the possibility of loosening and improving the reliability of the connection. During the assembly process, the outer tongue stop washer can serve as a buffer and protection to prevent scratches and damage to threads, surfaces, and parts. |
