Abstract
A configuration of lubrication nozzle including a large flow path to connect external oil supply tube with semi-circle cross section annular flow path, and three jet flow conduits with L form having interval of 120.degree. between adjacent channels to link annular flow path and outlet is created for oil-air or oil-mist lubrication system for high speed rolling-element bearings.
Claims4
A configuration of a lubrication nozzle for use with high-speed rolling-element bearings, comprising:
- a large flow path for connection with an external oil supply tube;
- a semi-circle cross section annular flow path in communication with said large flow path;
- and
- three jet flow conduits each having an L-shaped form and disposed at annular intervals of 120.degree. therebetween, said annular flow path being in communication with said three jet flow conduits,
- wherein said large flow path is defined in a cored circular column defining a cored inner chamber, and
- said semi-circle cross section annular flow path and said three jet flow conduits are included on an annular ring member located within said cored inner chamber.

A lubrication device, comprising:
- a circular cored column having a large flow path and an inner chamber defined therein;
- and
- a ring member located in said inner chamber of said circular cored column, said ring member having a semi-circular annular flow path defined about an outer periphery thereof, said annular flow path and said flow path of said cored circular column being in communication,
- wherein said ring member includes three jet flow conduits separated by approximately 120.degree. annular intervals, each of said jet flow conduits having an inlet and an outlet, each inlet being in communication with said annular flow path such that a communication path is formed to allow fluid flowing through said large flow path in said circular cored column to enter said inlet of each jet flow conduit via said annular flow path and exit each jet flow conduit via each outlet.
