Abstract

The disclosure provides an oil collecting ring and an oil supply lubricating device under the ring, belonging to the technical field of oil supply lubrication. Wherein the oil collector includes a first annular baffle, a second annular baffle and a curved blade, the curved blade is connected between the first annular baffle and the second annular baffle; one end of the curved blade is a blade tip, and the other end of the curved blade One end is the blade root, and the curved blade includes the lubricating oil incident section near the blade tip and the lubricating oil collecting section near the blade root. The first velocity direction of the lubricating oil on the inner surface of the lubricating oil incident section is consistent with the tangential direction of the curved blade , the first velocity is the relative velocity of the lubricating oil relative to the curved blade. In the present disclosure, the direction of the relative velocity of the lubricating oil on the inner surface of the lubricating oil incident section relative to the curved blade is consistent with the tangential direction of the curved blade, which greatly reduces the proportion of the lubricating oil flying out from the inner surface of the blade and improves the present disclosure. The oil collection efficiency of the oil collection ring.

Description

technical field [0001] The present disclosure relates to the technical field of oil supply lubrication, in particular to an oil collector ring and an oil supply lubrication device under the ring. Background technique [0002] High-speed rolling bearings are essential components in aero-engine systems. With the continuous improvement of aero-engine performance, the speed, load and temperature of aero-engine main shafts are also increasing. In order to ensure the stable operation of the spindle bearing under the conditions of high speed, high temperature and high load, high quality lubrication method is the necessary basis. [0003] At present, there are two commonly used lubrication methods for aero-engine main bearings: jet lubrication and under-ring lubrication. In a typical radial under-ring lubrication structure, the centerline of the nozzle is perpendicular to the centerline of the main shaft (vertical space), and the lubricating oil sprayed by the nozzle is collected b...
