Abstract
A mechanical device, comprising: a bearing including a fixed ring and a pivoting ring centered on a central axis and including an interface defined therebetween; and an interface lubrication system. An acceleration field pushes the stream of lubricant from a bearing first zone to a bearing second zone, each defining an angular sector around the central axis. The lubrication system comprises a set of peripheral channels passing through the fixed ring and including first channels positioned in the first zone and defining a first intake flow rate for bringing lubricant to the interface and second channels positioned in the second zone and defining a second intake flow rate bringing lubricant to the interface. The first flow rate is higher than the second flow rate. The interface receives a larger quantity of lubricant in the first zone than in the second zone. The mechanical device can be integrated into a machine.
