本性能规范涵盖直角偏置（RAO）万向节，该万向节设计用于在错位和/或偏置轴之间传递高达18000英寸磅的扭矩。RAO万向节是双万向节，可以容纳高达90度的复合角（任何方向上每个接头45度），取代安装在海军水面舰艇和潜艇上的远程操作员装置中的销和立方体万向节和齿轮箱。

This performance specification covers Right Angle Offset (RAO) universal joints designed to transmit up to 18,000 inch-pounds of torque between misaligned and/or offset shafts. RAO universal joints are double universal joints and can accommodate compound angles up to 90 degrees (45 degrees per joint in any direction) replacing pin-and-cube universal joints and gear boxes in remote operator arrangements installed on Navy surface ships and submarines.
