ABSTRACT:
A hydrokinetic spindle including a housing having a bearing in which the journal portion of a shaft is mounted. The shaft has a helical groove having a progressively decreasing cross-section formed on the journal surface thereof and extending from one end of the journal portion to the other which picks up a predetermined amount of fluid lubricant from fluid pickup posts leading from at least one fluid reservoir formed in the housing and directs the lubricant to and upon the shaft under pressure thereby maintaining a film of fluid lubricant under pressure between the shaft and the bearing of the housing. The housing and shaft are sealed in an artificial atmosphere.
