PLANETARY PRECESSION GEAR WITH THIN-LAYERED RUBER METAL

Abstract

In connection with spatial - spherical movement of one of gear wheels, the sliding friction appears between the gearing teeth of precession gear. In power precession-planetary gear, the decrease of sliding friction is obtained by executing the teeth of one wheel (as a rule the block satellite of gear) similar with that including conic-rollers, which are established with possibility to rotate round their axes. In precession gear cases, versions with rollers are not possible for using because of the small sizes of this gear. For this reason, one of more effective methods is a method proposed in the paper, which is based on the use of the thin-layered rubber-metal laminates between the gearing teeth.
