An improved compound planetary gear system. In embodiments, a compound planetary gear system includes at least one planet pinion including a main shaft having a first gear for meshing with a sun gear and a second gear for meshing with a ring gear, and a carrier for supporting the at least one planet pinion. Teeth of the first gear are configured with a first helical angle with respect to a longitudinal angle of the at least one planet pinion, teeth of the second gear are configured with a second helical angle with respect to the longitudinal angle of the at least one planet pinion, the first helical angle different from the second helical angle.

Planetary gearbox system and method therefor

A propped cantilever carrier is described that can be used in planetary gear systems. The carrier can comprise cantilevered arms extending outward from a central hub. At the end of each cantilever a post can extend downward that is configured to receive bearings and gears. A plate can comprise a hole for each post in the carrier. When the plate is coupled to the carrier it can hold the bearings and gears in place and provide added strength to the carrier. The strength benefits are large compared to the light weight of the carrier (with plate) apparatus.

Propped cantilever carrier

Briefly, implementations of claimed subject matter relate to methods and devices for coupling a first rotating shaft to a second shaft. In a particular implementation, an end of a plurality of resilient fingers of a resilient structure may be radially displaced to permit positioning of the resilient structure over a first shaft. An inwardly-directed portion of each of the plurality of the resilient fingers of the resilient structure may be secured to a channel located on an inner surface of a second shaft. After securing the resilient structure to the second shaft, the one or more resilient fingers of the resilient structure may be positioned within a slotted ladder ring encircling the first shaft.
