Abstract

539,873. Crankshaft bearings. BAILEY, R. W. H. May 10, 1940, No. 8492. [Class 12 (i)] The journal bearing E of an internal-combustion-engine crankshaft has a hollow interior communicating by two radial holes F<SP>1</SP> with grooves D<SP>1</SP> in the liner D which has holes C' leading to a groove C<SP>2</SP> in the crank-case part B, oil being supplied under pressure to groove C<SP>2</SP>. The oil is supplied to the centre of the journal E when the holes F<SP>1</SP> and grooves D<SP>1</SP> register, and is then returned by centrifugal force to the holes F' to lubricate the liner D between the grooves D' throughout an arc of at least 90 degrees before the maximum load comes on to the bearing. The grooves D' do not extend more than 40 degrees on either side of the horizontal and the holes F<SP>1</SP> are arranged from 80 degrees to 100 degrees in front of one position of maximum load. To distribute the oil, flats are formed on the journal at the ends of the holes F<SP>1</SP> extending over three-fifths of the bearing width and backed off at its trailing edge preferably in the shape of a broad arrow.
