Abstract

A lubricating system for supplying oil to the bearings of a shaft having a central oil pumping passage open at one end. An oil delivery tube reaches into the oil pumping passage. To achieve a positive transfer of the oil from the oil delivery tube to the inner wall of the oil pumping passage, means are associated with the upper end of the oil delivery tube for bringing the oil onto the inner wall of the oil pumping passage.
