A Conical Washer Spring also known as a Belleville washer, is a type of washer that is designed to provide a high degree of spring tension when compressed. It is placed between the parts Coupler Cylinder and Rocker Arm and when they are engaged, the spring compresses, creating tension between the parts. This tension helps to ensure that the Rocker Arm remains securely in the Coupler Cylinder place, even when subjected to high pressures or vibrations.Attributes:• Provides excellent load distribution, reducing stress concentrations on the fastener• Provide proper alignment and stability in units subjected to vibration and thermal expansionApplications:A Conical Washer Spring is used to prevent damage to the surface of the Coupler Cylinder and improve the overall stability of the joint.
