DEVICE FOR LUBRICATION OIL PATH IN JOURNAL BEARING OF CONTRA-ROTATING PROPELLER SHAFT

摘要

PURPOSE: A device for supplying lubricating oil of a journal bearing for a contra-rotating propeller is provided to prevent erosion caused by friction, and to minimize heat generation by supplying lubricating oil for forming an oil film. CONSTITUTION: A device for supplying lubricating oil of a journal bearing for a contra-rotating propeller comprises an external rotary shaft(10), an internal rotary shaft(20), and lubricating oil supply ports(22). The internal rotary shaft is installed within the external rotary shaft, and transfers power. The lubricating oil supply ports are connected to a lubricating oil supply path(21) of the internal rotary shaft, and formed in a radial shape. Oil pockets(23) are formed in the end of the lubricating oil supply ports.
