Abstract
A lubricant feeding system for shaft and hub profile assemblies that can move longitudinally along an axis. A first exterior assembly member (e.g., shaft or hub) encloses at least partly a second interior member (e.g., hub or shaft) along the circumference. At least one distributing channel, extending circumferentially over at least part of the inner circumference, is provided in the region of the profile base. This distributing channel is coupled with at least one lubricant feeding channel extending towards the external circumference of the assembly exterior member The invention includes a distributing member extending circumferentially over the length of the distributing channel, splits the distributing channel into a first partial area located radially outward and a second partial area located radially inward. The distributing member and the distributing channel are designed to form, when they co-operate, a plurality of valve areas between the first and the second partial of the distributing channel.
