Abstract:

A blower motor assembly includes a blower wheel and a motor. The blower wheel includes an integrally formed hub. The motor includes a shaft rotatable about an axis. The hub presents a radially inner hub surface that at least in part defines a hub opening. The inner hub surface defines an inner cross-sectional dimension. The shaft is axially received within the hub opening, such that the blower wheel is supported by the shaft for rotational movement. The shaft includes a toothed region defining a plurality of arcuately spaced apart teeth. Each of the teeth includes a cutting edge. The teeth present an outer cross-sectional dimension that is great than the inner cross-sectional dimension of the inner hub surface, such that the cutting edges of the teeth cut a plurality of grooves in the inner hub surface as the shaft is axially received in the hub opening.

Abstract:

An electric motor assembly includes a rotor, a stator, and a gear assembly. The gear assembly includes a drive gear, a ring gear, and an intermediate gear disposed between and engaging each of the drive gear and the ring gear. The gear assembly further includes a carrier supporting the intermediate gear and being fixed relative to the stator so as to be stationary relative thereto. The ring gear is rotatable relative to the carrier and the stator.
