Lubricant applying system for a rolling bearing

Abstract

In a lubricant application system, a prescribed volume of lubricant is transferred from a lubricant discharge port ( ) of a prescribed liquid volume discharge device to a rolling element ( ) of a rolling bearing ( ) in a state in which the lubricant discharge port ( ) is positioned directly above and sufficiently close to the rolling element ( ), whereby the lubricant is applied to the interior of the rolling bearing ( ). Further, the application system inspects whether or not a prescribed volume of lubricant is injected from the discharge device for injecting a lubricant into the interior of a rolling bearing ( ). A laser beam (L ) is irradiated between a lubricant discharge port ( ) of the lubricant discharge device and the rolling bearing ( ), and a reflected laser beam (L ) reflected by the lubricant when it is discharged from the lubricant discharge port ( ) is received by a photoreceptor ( ) disposed on the optical axis of the reflected laser beam (L ), whereby whether or not the lubricant is applied to the rolling bearing ( ) is determined-based on an output from the photoreceptor ( ).
