Mechanical device comprising a bearing and a lubrication system, implementing machine and method

A method for implementing a mechanical device having:

• a bearing including a fixed ring and a pivoting ring that are centered on a central axis and include an interface defined between them;
• and
• a system for lubricating the interface, configured to bring a flow of lubricant from at least one supply channel to the interface through the fixed ring;
• in which an acceleration field tends to push the stream of lubricant from a first zone to a second zone of the bearing, each defining an angular sector around the central axis;
• wherein the lubrication system comprises a set of peripheral channels passing through the fixed ring and including, first channels that are positioned in the first zone and that define a first intake flow rate for bringing lubricant to the interface and second channels that are positioned in the second zone and that define a second intake flow rate bringing lubricant to the interface, the first intake flow rate being higher than the second intake flow rate, such that the interface between the rings of the bearing receives a larger quantity of lubricant in the first zone than in the second zone,
• the method comprising successive steps of:
• a) forming orifices through the fixed ring of the bearing, these orifices being configured to receive the lubrication system and define the peripheral intake channels bringing a stream of lubricant to the interface between the rings of the bearing;
• b) assembling the lubrication system and the bearing;
• and
• c) supplying lubricant to the lubrication system, such that the interface between the rings of the bearing receives a larger quantity of lubricant in the first zone than the second zone.
