ABSTRACT:
An automatic lubricant metering device consists essentially of a housing (4), from inside of which a piston (5) is conveying a lubricant (15) through a feeder line (12) to the lubricating location (2) of a revolving shaft (1). The automatic feature consists of that the spring-loaded piston (5) is connected with a pin (6) made of an abradable material. The advance of the piston (5) is a function of the abrasion of the pin (6) on the appropriately roughened surface of the shaft. The lubricant is contained in a compressible bellows (11) equipped with a feeder line (12) to the lubricating location (2). The feed to the lubricating location is conducted in the area of the shaft through a pipe (13) located preferably without contact in a center bore (14) of the shaft. The outlet of this pipe opens into a radial bore (16) connected with the lubricating location (16).
