Electric drive assembly

A reduction drive assembly, comprising:

• a housing comprising:
• a spindle having a first end and a second end opposite the first end, the spindle defining an aperture that extends axially between the first end and the second end;
• and
• a flange extending radially outward from the second end of the spindle, wherein an outer surface of the spindle and the flange form at least one fillet corner;
• a motor output shaft coupled to and driven by a motor, the motor output shaft extending through the aperture of the spindle;
• a planetary gear assembly comprising:
• a sun gear coupled to and driven by the motor output shaft;
• and
• a plurality of planet gears meshed with and driven by the sun gear, each of the plurality of planet gears having a first stage gear and a second stage gear;
• a fixed ring gear coupled to the first end of the spindle and housing the second stage gear, the fixed ring gear being meshed with the second stage gear of each of the plurality of planet gears;
• an output hub;
• a rotating ring gear coupled to the output hub and meshed with the first stage gear of each of the plurality of planet gears to cause the output hub to rotate about the spindle of the housing;
• a set of bearings positioned radially between the outer surface of the spindle and an inner surface of the output hub and axially between the fixed ring gear and the flange of the housing to facilitate rotation of the output hub;
• and
• a spacer ring positioned between the flange of the spindle and the set of bearings and adjacent the at least one fillet corner to reduce stress of the housing.
