Precision and Reliability for Mission-Critical Applications

When it comes to defense applications, every component must stand up to the harshest of environments.

The following development example of a complete shaft assembly for an amphibious assault vehicle demonstrates Belden’s commitment to tackle the toughest applications.

Designed to withstand both nuclear and biological contamination, the joint yokes and shaft of the vehicle were constructed of 7075-T651 aluminum to provide a lightweight, high-strength, corrosion resistant solution. It was necessary to modify standard pin and block designs in various materials to create a custom assembly. The bushing and pins were made from hardened 416 stainless steel to combat corrosion and prevent galling and premature wear of the yoke components. The pin and block section of the universal joints were outfitted with neoprene boots to prevent contaminates from invading the assembly. The boots were molded specifically for the shaft assembly to protect the joints and provide maintenance-free operation for extended periods of time. The end result was a solid component that met the customer’s exact application specifications.
