Transmission mechanism with internal lubrication and associated electric propulsion unit

Abstract

A transmission mechanism with internal lubrication, including a speed reduction device having at least a first transmission shaft extending along a first axis of rotation and coaxially bearing a first gear wheel, and a hollow casing including a base and a peripheral wall integrally formed with the base, the peripheral wall partially surrounding the speed reduction device. A lubricant receiving and distributing collector is positioned in the casing between the peripheral wall and the first axis of rotation. The lubricant receiving and distributing collector includes at least a bottom, an outer perimeter and an additional collecting device connected to the outer perimeter, the additional collecting device bearing on the peripheral wall and/or the base of the casing.
