  • Spindle nut retainer system
    Patent number: 11959506
    Abstract: A spindle nut retainer is used with a spindle with a flat portion on its threaded end. The flat portion interrupts the threads on the threaded end. A washer with a mating flat portion is slidably mounted over the threaded end and a nut is removably threaded to the threaded end of the spindle against the washer to set the preload on bearings. The nut retainer overlays a plurality of the corners of the nut and engages the threaded portion of the spindle with tangs. A majority of the tangs are flexed or bent to remain in biased contact with the threads on the spindle. Some of the tangs are located over the flat portion and remain unbent. The tangs resist rotation of the nut by engagement with the flat portion where it meets the threads.
