Abstract
A system for gearing, the system comprising a toothed wheel mounted on a shaft, the wheel being pierced by channels fed with lubricant, each channel opening out to the toothed periphery of the wheel. Said wheel is mounted on an end portion of the shaft, so as to be capable of being rotated by said shaft, said end portion being hollow so as to present an inside chamber, said chamber opening out to the end of the shaft via an orifice. Said channels communicate with said chamber. The system includes an injector for injecting lubricant into the chamber, the injector being situated outside the chamber and facing said orifice in such a manner as to inject the lubricant through said orifice, the lubricant penetrating into and flowing along the channels to the toothed periphery of the wheel under the effect of centrifugal force associated with rotation of the shaft.
