CLAIMS
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.
2. A planetary wheel drive as claimed in claim 1, further comprising:
said output stage includes an output planet pin;
said single wall output planet pin includes a hole therein to receive said output planet pin therein;
said hole of said output planet carrier interrupts said internal spline of said output planet carrier creating a discontinuity of said internal spline;
said output planet pin includes a flanged head; and,
said output planet pin is pressed into said hole in said single wall output planet carrier.
3. A planetary wheel drive as claimed in claim 2, further comprising:
an output planet thrust plate;

said output planet thrust plate includes a bore therethrough;
said output planet thrust plate includes a counterbore concentric with said bore;
a bore through said output planet pin;
said bore through said output planet pin is threaded;
a bolt;
said bolt includes threads thereon;
said bolt threadedly interconnects said bolt with said threaded bore of said output planet pin interconnecting said output planet thrust plate to said output planet pin securing said output planet pin to said single wall output planet carrier adding single wall output planet carrier strength and stiffness to said single wall output planet carrier; and,
said output planet thrust plate interengages said input stage limiting axial movement of said single wall output planet carrier with respect to said stationary spindle and preventing axial retraction of said locking lug of said single wall output planet carrier from said notch of said bearing nut.
4. A planetary wheel drive as claimed in claim 3, further comprising:
said output planet pin is flanged on one end thereof;
a relief in proximity to said flange of said output planet pin; and,
said output planet pin pressed into said hole of said output planet carrier.
5. A planetary wheel drive as claimed in claim 3, further comprising:
a plurality of notches in said bearing nut enabling rotational adjustment of said single wall output planet carrier with respect to said bearing nut.
6. A planetary wheel drive as claimed in claim 3, further comprising:
a support for an output planet gear residing between said output planet gear and said output planet pin;
said support enable said planet gear to rotate about said output planet pin;
said output planet thrust plate is a thrust surface for said support of said output planet gear,
7. A planetary wheel drive, comprising:
a stationary spindle and a rotatable housing;
an input stage and an output stage:
said output stage comprises:
a single wall output planet carrier, said single wall output planet carrier is generally cylindrically shaped and includes a partially closed single wall at one end thereof and a cylinder wall extending from said partially closed single wall,

said partially closed single wall includes a through hole therein;
a planet pin press fit in said through hole;
said cylinder wall extending from said partially closed single wall includes an internal spline proximate said partially closed single wall; and,
said cylinder wall extending form said partially closed single wall includes a locking lug extending therefrom;
a bearing nut includes internal threads;
said bearing nut further includes a notch therein;
said stationary spindle is generally cylindrically shaped and has an exterior, said exterior includes external threads thereon;
said internal threads of said bearing nut mate with said external threads of said stationary spindle;
said stationary spindle includes an external spline which mates with said internal spline of said single wall output planet carrier preventing rotation of said single wall output planet carrier; and,
said locking lug extending from said cylinder wall of said single wall interengages with said notch of bearing nut preventing rotation of said bearing nut with respect to said stationary spindle thus preventing unthreading of said bearing nut.
8. A planetary wheel drive as claimed in claim 7, further comprising:
a washer;
said washer includes a tab;
said washer abuts said bearing nut; and,
said tab of said washer is aligned with said notch of said bearing nut;
said tab orients said washer with respect to said bearing nut.
9. A planetary wheel drive, comprising:
a stationary spindle;
an input stage and an output stage: said output stage comprises: a single walled output planet carrier,
said single walled output planet carrier includes an internal spline,
said single walled output planet carrier includes a through planet hole, said through planet hole interrupts said internal spline, an output planet pin,

said output planet pin pressed in a through planet hole, and,
an output planet gear;
a lugged bearing nut locking device;
a thrust plate;
a bolt; and,
said bolt affixes said thrust plate to said output planet pin.
