Patent number: 9511661Abstract: A driven wheel unit includes an electric motor coupled to a two-speed, three stage planetary drive assembly and has a width dimensioned for traveling between rows of crop. A wheel hub is supported on an outer surface of a fixed housing by large diameter wheel bearings surrounding both a motor-containing cavity and an adjacent cavity containing first and second planetary stages. Nested radially and surrounding the two planetary stages are two SAHR disc clutches including pistons engaging inner and outer surfaces of a compact piston guide member. The third stage planet carrier defines a cap and is fixed to an axially outer end of the wheel hub. A third stage ring gear has an outside diameter approximately equal to that of the wheel bearings and has an inside diameter fixed to the housing by a planar, annular wheel bearing retainer plate that is fixed to an end of the housing.Type: GrantFiled: March 12, 2015Date of Patent: December 6, 2016Assignee: DEERE & COMPANYInventors: Douglas K.

Publication number: 20150337945Abstract: A shaft retention and lubricating fluid delivery system and method are described, such as for mounting a pinion shaft to a pinion carrier and providing lubricating fluid to a pinion and pinion bearing. A retaining pin fits inside a pinion shaft radially bore and a pinion carrier radially bore to constrain the axial and rotational movement of the pinion shaft relative to the pinion carrier. Pressurized lubricant and centrifugal force from pinion carrier rotation aids in maintaining the retaining pin in a retaining position. When the pinion carrier is not rotating, a cap screw prevents the retaining pin from disengaging. An annular gap passage between the cap screw and the interior of the pinion shaft allows lubricating fluid to reach the shaft, pinion and pinion bearing.Type: ApplicationFiled: May 20, 2014Publication date: November 26, 2015Applicant: Deere & CompanyInventor: Kyle K.
