Title:
OIL SUPPLY MECHANISM OF ROTATING MACHINERY AND ROTATING MACHINERY HAVING OIL SUPPLY MECHANISM
Document Type and Number:
WIPO Patent Application WO/2020/083309
Kind Code:
A1
Abstract:
An oil supply mechanism (200) of rotating machinery and rotating machinery having the oil supply mechanism (200). The oil supply mechanism (200) comprises: an oil pump device (2), wherein the oil pump device (2) is connected to a rotating shaft (1) of rotating machinery, such that the amount of oil pumped by the oil pump device (2) increased as a rotating speed of the rotating shaft (1) increases; a main oil supply channel (10), wherein the main oil supply channel (10) is formed in the rotating shaft (1) substantially in the axial direction of the rotating shaft (1); and a bypass oil channel (40), wherein the bypass oil channel (40) communicates with the main oil supply channel (10), and part of lubricating oil in the main oil supply channel (10) can flow out through the bypass oil channel (40). The bypass oil channel (40) extends in a direction substantially perpendicular to the rotating shaft (1). The bypass oil channel (40) is configured such that a radial distance (Rx) from an outlet of the bypass oil channel (40) to the axis of the rotating shaft (1) is greater than the radius (R) of the rotating shaft (1). The oil supply mechanism (200) ensures that the amount of oil supplied in a low-speed operating condition meets lubrication requirements, and reduces the amount of oil supplied in a high-speed operating condition so as to avoid a high oil circulation rate, thereby improving the efficiency of rotating machinery.
