  • Method of independently measuring bearing preload in an axle assembly
    Patent number: 6907773
    Abstract: A method and apparatus to independently measure the bearing pre-load of a pinion gear and differential case an assembled axle assembly. The ring gear and pinion gear are positioned within a backlash so that there is no engagement therebetween. The pinion shaft and differential case are rotated independently in synchronization maintaining the relative positions and the torque to rotate the pinion shaft and differential case are independently measured.
    Type: Grant

  • Method of independently measuring bearing preload in an axle assembly
    Publication number: 20030154775
    Abstract: A method and apparatus to independently measure the bearing pre-load of a pinion gear and differential case an assembled axle assembly. The ring gear and pinion gear are positioned within a backlash so that there is no engagement therebetween. The pinion shaft and differential case are rotated in synchronization maintaining the relative positions and the torque to rotate the pinion shaft and differential case are independently measured. Once the independent pre-loads are measured, the ring gear is allowed to freely rotate being driven by the pinion gear and the overall torque to rotate the entire axle assembly can be measured.
