Abstract
Planetary reduction gear comprising at least one stage consisting of an input plant pinion (7), of spider gears (8, 9, 10) mounted on a spider (11) secured to an output shaft and to a fixed crown wheel (12). The spider gears are mounted so that they can float radially in the spider and the toothings of the meshing elements are offset such that the radial resultant of the forces exerted, on the one hand, between the crown wheel and the spider gears and, on the other hand, between the spider gears and the planet pinion points either toward the planet pinion in order to reduce the noise of the reduction gear, or toward the weakest elements in order to increase the load capability of the reduction gear.
