1. A planetary wheel drive, comprising:

  • a stationary spindle and a rotatable output housing;

    an input stage and an output stage;

    said input stage drives said output stage;

    said output stage includes a single wall output planet carrier fixed against rotation;

    said single wall output planet carrier includes an interior spline;

    said stationary spindle includes an exterior spline;

    said interior spline of said single wall output planet carrier slidingly mates with said exterior spline of said stationary spindle securing said single wall output planet carrier against rotation but permitting axial movement between said output planet carrier and said stationary spindle;

    said single wall output planet carrier includes a locking lug;

    said stationary spindle includes exterior threads extending circumferentially therearound;

    a bearing nut having internal threads;

    said internal threads of said bearing nut mates with said exterior threads extending circumferentially around said stationary spindle securing said internal threads of said bearing nut thus securing said bearing nut to said spindle;

    said bearing nut includes a notch therein; and

    ,said notch of said bearing receives said locking lug of said single wall output planet carrier preventing rotation of said single wall output planet carrier with respect to said bearing nut and preventing said bearing nut from disengaging said stationary spindle wherein said locking lug retains said bearing nut in place preventing said bearing nut from backing off said stationary spindle.
