Bearing lubricating injector

Claim 1

A bearing lubrication injector for use in an engine having a housing, a shaft, a ball bearing including an inner race and an outer race for rotatably mounting the shaft in said housing, and a source of lubricant for said bearing, said injector comprising: a first ring member having a substantially annular cross section coaxially secured to the shaft adjacent the inner race of the bearing, said ring member having an outer ramp surface which increases in diameter toward a first axial end of said first ring member adjacent the inner race; a second ring member having a substantially annular cross section; means for coaxially securing said second ring member to said first ring member such that the radially inner surface of said second ring member is radially spaced apart from said ramp surface to thereby define fluid passage means for axially transferring fluid between said radially inner surface and said ramp surface, said passage means having an inlet axially spaced from said inner race and in fluid communication with said source of lubricant; and whereby upon rotation of said shaft, lubricant is centrifugally forced along said ramp surface and axially ejected from between said radially inner surface and said ramp surface into said bearing.
