Abstract
A speed reducer for a powertrain includes, in an orthogonal frame of reference: a reduction device including a first shaft extending along a first axis of rotation and coaxially carrying a first toothed wheel, and a housing with a hollow shape including a base and a peripheral wall integrally formed with the base, the peripheral wall partially surrounding the reduction device. Also included is a lubricant receiving and distributing collector arranged in the housing between the peripheral wall and the first axis of rotation. The lubricant receiving and distributing collector includes a first reservoir and a second reservoir which are arranged on either side of the first toothed wheel.

Speed reducer for a powertrain, comprising, in an orthogonal frame of reference:
- a reduction device comprising a first shaft extending along a first axis of rotation and coaxially carrying a first toothed wheel,
- a housing with a hollow shape comprising a base and a peripheral wall integrally formed with the base, the peripheral wall partially surrounding the reduction device,
- a lubricant receiving and distributing collector arranged in the housing between the peripheral wall and the first axis of rotation,
- wherein the lubricant receiving and distributing collector comprises a first reservoir and a second reservoir which are arranged on either side of the first toothed wheel,
- wherein the first reservoir and the second reservoir are connected via a first gutter conveying a lubricant from the first reservoir to the second reservoir under the effect of gravity, and
- wherein the first reservoir and the second reservoir are connected via a second gutter conveying the lubricant from the first reservoir to the second reservoir under the effect of gravity, so that the first reservoir, the second reservoir, the first gutter and the second gutter form a common receptacle able to receive the lubricant projected within the housing.

- a lubricant receiving and distributing collector arranged in the housing between the peripheral wall and the first axis of rotation,
- wherein the lubricant receiving and distributing collector comprises a first reservoir and a second reservoir which are arranged on either side of the first toothed wheel, and
- wherein the first reservoir and the second reservoir are connected via a first gutter and a second gutter which are separate and which distribute the lubricant indiscriminately between the first reservoir and the second reservoir under the effect of gravity, so that the first reservoir, the second reservoir, the first gutter and the second gutter form a common receptacle able to receive a lubricant projected within the housing.

- wherein the lubricant receiving and distributing collector comprises a first reservoir and a second reservoir which are arranged on either side of the first toothed wheel,
- wherein the lubricant receiving and distributing collector comprises at least one bottom, an outer perimeter and a central opening arranged between the first reservoir and the second reservoir, into which opening the first toothed wheel is partially inserted so as to be able to project lubricant from the toothing towards the bottom of the lubricant receiving and distributing collector, the bottom of the lubricant receiving and distributing collector completely surrounding the central opening, and
- wherein an inner perimeter of the central opening delimits inner walls of the lubricant receiving and distributing collector.
