ABSTRACT:
In an elastic coupling with two similar central gears assemblable on respective shaft ends and having rows of teeth, respectively, disposed adjacent one another, and a planet gear with a row of teeth having an angular pitch equal to that of the rows of teeth of the central gears, the central gears being turnable elastically resiliently so that the flanks of the teeth of the central gears form generally wedge-shaped virtual tooth gaps having a profile varying with reciprocal turning of the central gears, the teeth of the planet gear being also generally wedge-shaped and projecting into the generally wedge-shaped virtual tooth gaps, the tooth flanks of the teeth of the planet gear being in direct contacting engagement with the tooth flanks of the teeth of the central gears, and the teeth of the planet gear and the teeth of the central gears being spring-biased radially toward one another so that the teeth of the planet gear remain fully in engagement in the virtual tooth gaps.
