1. A gear, comprising:
- a toothed portion having an axial bore;
a hub disposed within said axial bore, said hub being positioned within said axial bore to define a space between said hub and said toothed portion; and
an elastomeric isolator disposed in said space to provide a damping relationship between said toothed portion and said hub, wherein said elastomeric isolator includes a ring having a first dimension and a plurality of spheroids having a second dimension disposed on said ring.

Abstract
A planet gear includes a toothed portion having an axial bore, a hub disposed within the axial bore such that a space is defined between the hub and the toothed portion, and an elastomeric isolator disposed in the space. A gear is quieter in operation through configuration such that the gear includes a toothed portion having an axial bore and a hub coaxially orientable within the axial bore, and an elastomeric isolator is positioned between the hub and the toothed portion.
