Abstract
A drivetrain for coupling a motor to a mixer shaft within a mixer includes a sun gear connectable to a rotor of the motor. The drivetrain also includes a plurality of stepped planetary gears. Each of the stepped planetary gears includes a first tooth section and a second tooth section. A first ring gear is mounted such that the first ring gear is fixed. The first ring gear and the sun gear are meshed with the stepped planetary gears at the first tooth section. A second ring gear is meshed with the stepped planetary gears at the second tooth section. The sun gear, the stepped planetary gears, the first ring gear, and the second ring gear collectively form a single stage planetary gear set of the drivetrain.
