Multiple-row epicyclic gear

摘要

A multiple-row epicyclic gear includes a carrier with planet gears arranged in rows, as well as a composite central ring gear, having major crowns, with friction spacer rings disposed there between, are also mounted in the housing. The elements of the central ring gear are axially spring loaded. The end faces of the frictional spacer rings and counter-oriented end faces of the major crowns have tapered surfaces being in frictional contact. The friction spacer rings are spliced and arranged to bring their outer cylindrical surfaces into frictional contact with the inner cylindrical surface of the housing. The planet gears are disposed on the carrier in rows in corresponding apertures (or through openings) formed in the carrier. The optimal cone apex angle (δ) of the contacting tapered end faces of the major crowns and tapered end faces of the friction spacer rings is in the range 60-90°.

1. A multiple-row epicyclic gear comprising a housing with an externally toothed central shaft mounted therein; a carrier with planet gears mounted in rows thereon; and a central internally toothed ring gear being composite and having major crowns, and friction spacer rings disposed between said major crowns, said major crowns and said friction spacer rings being pressed in an axial direction, wherein end faces of the friction spacer rings and counter-oriented end faces of the major crowns have tapered surfaces being in frictional contact, wherein the friction spacer rings are spliced and arranged to bring their outer cylindrical surfaces into frictional contact with the inner cylindrical surface of the housing.
