Abstract
1345769 Crank-shafts BURMEISTER & WAINS MOTOR-OG MASKINFABRIK AF 1971 AS 28 May 1971 [6 June 1970] 17947/71 Heading F2U A crank-shaft comprises two members 1, each comprising at least one crank throw and a pin 3 co-axial with the main bearing and protruding towards the other pin 3 to which it is connected by a sleeve 9 shrunk on to the outer surfaces of the pins, the mating surfaces of the pins 3 and sleeve including non-cylindrical parts 10, 11, 13, 14 (e.g. screw threads, circumferential grooves ridges or steps-Figs. 5 to 7, not shown). The ridges may be triangular with an apex angle of 60 degrees. The ring may have a higher yield stress than the crank throws. The threads &c. reduce the bearing stress when the pin diameter is greater than the mating surface axial length. Bores 38 may be used for balancing.
