Abstract
Coaxially spaced externally toothed gears are bridged and interconnected by a resilient annular gear formed from a coil of flexible material having corrugations shaped to engage the gear teeth. The external peripheral of the annular gear is enclosed by a sleeve member maintaining it in resiliently wedged circumferential driving engagement with the externally toothed gears.
Claims10
A torsionally resilient gear coupling for connecting axially spaced driving and driven members, said coupling comprising an externally toothed gear connected to each of said members interconnected by a resilient annular gear bridging the space between the gears, said annular gear comprising a plurality of concentric, uniformly corrugated flexible laminas, the corrugations thereof being shaped to mesh tangentially with each other and with the teeth of the externally toothed gears;
- a concentric sleeve member extending axially over the periphery of the annular gear and in retentive contact therewith, said sleeve member supporting the radial component of tangential gear tooth forces transmitted to the annular gear, said annular gear being in resiliently compressed driving engagement between the internal periphery of the sleeve member and the externally toothed gears, and means enclosing the ends of the sleeve member and annular gear.
