ABSTRACT:
An improved planetary gear drive, employing multiple countershafts to reduce the loads carried by the individual components, is disclosed wherein at least one helical gear set having sets of oppositely inclined oblique teeth is mounted for axial movement on a common shaft to transmit power from a drive component to a power component. A compression spring, disposed contiguous with one face of the helical gear set, cooperates with the oppositely inclined teeth of the helical gear set to resiliently move the helical gear set axially along its shaft to equalize the axial force components on its oppositely skewed sets of teeth. The invention may be embodied at any one of several different points in the gear train.
