Randolph Dozier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Planetary wheel drive single wall lugged output carrier
    Patent number: 10612645
    Abstract: A planetary wheel drive uses a single wall output planet carrier includes an internal spline fixed against rotation through an interconnection with an external spline of the stationary spindle. A locking lug of the single wall output planet carrier extends into a notch of a bearing nut. The locking lug prevents the bearing nut from unthreading itself from the stationary spindle. An output planet thrust plate is bolted to an output planet pin.
    Type: Grant

  • Compact planetary wheel drive
    Patent number: 10093177
    Abstract: A compact planetary wheel drive uses a high speed input planet carrier partially residing with a stationary spindle, and, an input planet gear engaging an internal ring gear within the stationary spindle. Inclusion of the input planet gear within the stationary spindle enables use of an additional stage of the planetary wheel drive while keeping the planetary wheel compact. Two and three stage planetaries may be accommodated with use of the same internal output ring gear of the rotatable output housing.
