Abstract

A lubricant supplying device includes a feed pump that serves to pump lubricant from a lubricant reservoir to at least one lubrication point. A method for operating the lubricant supplying device includes measuring at least one operating parameter, such as temperature (T), of at least one part of a system to be lubricated and/or of the lubricant and/or of the environment. The at least one measured operating parameter (T) is supplied to a controller, where a required volumetric flow ({dot over (V)}target) of lubricant is determined based on a stored functional relationship ({dot over (V)}target=ƒ (T)) that generates the required volumetric flow ({dot over (V)}target) based upon the measured operating parameter (T). The feed pump is then actuated in order to achieve the determined, required volumetric flow ({dot over (V)}target).
