LUBRICATING OIL SUPPLYING ARRANGEMENT FOR AN APPARATUS HAVING A ROTATING APPARATUS SHAFT

摘要

A lubricating oil supplying arrangement for an apparatus having a rotating apparatus shaft with an oil pump is arranged at one end of the apparatus shaft (23) and is driven by this apparatus shaft (23). A pump housing (2) has a pocket (3) in the form of a chamber open on one side, in which two co-operating displacement elements (4, 5) are so arranged that the pump housing (2) covers the displacement elements (4, 5) axially on both sides at least in an operative region and in the circumferential direction over a maximum of 180 DEG . The displacement elements (4, 5) are held in position by a pump shaft (13). This pump shaft (13) is connected via coupling elements to the apparatus shaft (23) so that they rotate together. This permits a construction having narrow tolerances that is easy to assemble.
