Abstract:
A method for a controlled supply of lubricant to an antifriction bearing which comprisesan inner bearing ring and an outer bearing ring mounted in a concentric arrangement so as to define opposing inner and outer races on the inner and outer rings respectively, a plurality of rolling elements mounted between the inner and outer races, and a duct extending through at least one of the inner and outer rings and terminating at an outlet opening which communicates with the associated race,said method comprising the steps of intermittently supplying lubricant to the duct of the antifriction bearing so as to flow through the outlet opening and directly into the region of the rolling elements, with the amount of the lubricant for each intermittent supply being determined from a predetermined basic quantity which is modified as a function of operating data which are continuously acquired from the antifriction bearing.
