Abstract
A roller bearing construction is provided for use between a crank-shaft and a connecting rod wherein the bearing assembly has lubricating oil sealed therein. In such application, centrifical force causes oil to move in a circular pattern tending to take a position radially remote from the inner race. Internal walls or baffles are provided that partially break up such oil movement, the walls or baffles being so constructed that some of the oil can pass therethrough to an adjacent compartment and other oil is directed through a channel to discharge near the inner race. Appropriate seals and heat dissipation means are included in the bearing assembly.
Claims2
An antifriction bearing assembly comprising:
- (a) an annular outer race adapted to be supported for orbiting about an axis remote therefrom;
- (b) an inner annular race disposed in said outer race and defining an annular lubricant-receiving space therewith;
- (c) antifriction bearing elements disposed between said races in engagement therewith;
- (d) wall means in fluid-tight relation to said outer race and orbital therewith, said wall means having separate inner compartments in fluid communication with each other, and in fluid communication with said annular lubricant-receiving space, said compartments being defined in part by radially extending circumferentially spaced flanges secured to said wall means;
- and
- (e) a series of inserts secured to said wall means which respectively define with inner surfaces of said compartments a series of lubricant channels opening toward each other into the annular lubricant-receiving space, and said inserts also having a plurality of lubricant holes therethrough for conducting lubricant from the bearing elements to a reservoir in communication with said inner compartments.
