ABSTRACT:
In the periodic lubrication of a circulating link chain conducted around chain guide wheels, irrespective of the chain speed a predetermined constant quantity of lubricant is supplied to each lubrication point on the chain in a time which continually changes with the chain speed. The lubricant is supplied by a series of lubricating piston pumps which are operated successively during each lubrication period in synchronism with the speed of the chain. The working stroke of each pump is the same and is effected by the displacement of a member having an inclined surface arranged to be engaged by one or more rotating governing cams carried by a driving shaft which is coupled to a shaft driven by one of the chain wheels. The driving shaft is coupled and uncoupled at the beginning and end of each lubrication period by means which counts the lubrication points of the chain passing a sensor and is thus also dependent on chain speed.
