ABSTRACT:
A machine with bearing-mounted rotors includes a housing (1) and two cooperating rotors erected therein which are supported on bearings (8-9 and 11-12, 17-18 and 20-21, respectively) with shafts ends (5 and 5A, 14 and 14A, respectively) at their ends. The shaft ends (5, 14, respectively) of each of the rotors (2 and 3) rest in a pair of bearings (8-9, 17-18, respectively). The bearings (8 and 9) of the one pair are situated opposite the bearings (17 and 18) of the other pair. At least one spray element (27) is erected between the bearings (8 and 9, 17 and 18, respectively) of the pairs (8-9 and 17-18) for spraying lubricating liquid on the bearings (8-9-17-18). Between the bearings (8 and 9, 17 and 18, respectively) of each pair (8-9 and 17-18), a ridged ring (35, 35A respectively) is provided around the shaft and (5, 14, respectively). Each ridged ring (35, 35A) is provided with a protruding ridge (36, 36A, respectively) on its entire outer perimeter. The spray element (27) has nozzles (32, 32A, respectively) directed towards the protruding ridges (36, 36A, respectively) of the ridged rings (35 and 35A).
