CALCULATION SHEET OF SHAFTING (BY ABS)

1. PRINCIPAL PARTICULAR OF MAIN ENGINE TYPE: HHM-MAN-B & W 5S60MC MK VI

NO.OF CYLINDER： 5

CYLINDER BORE： 600mm

PISTON STROKE: 2292mm S.M.C.R. : P=8550 KW REVOLUTION: N0 =92 rpm

2. INTERMEDIATE SHAFT DIAMETER

dmin =F * K 3 P * 560 N0 (B+160) HERE: F = 100 K = 1 B = 600 N/mm2

SO:

dmin =100 * 1 * 3 8550 * 560 92 (600+160) = 409mm WE TAKE D= 425 mm.

3. SCREW SHAFT DIAMETER

dp =100 * K 3 P * 560 N0 (B+160)

HERE: Krear = 1.22 Kfront = 1.15 B = 600 N/mm2

SO: d p rear = 100 * 1.22 * 3 8550 * 560 92 (600+160) =499 mm WE TAKE Drear= 523 & 525 mm.

dp front = 100 * 1.15 * 3 8550 * 560 92 (600+160)

= 470 mm WE TAKE D front =527 & 520 mm.

4. BOLTS FOR FLANGE

4.1 BOLTS FOR FLANGE BETWEEN M/E AND INTERMEDIATE SHAFT db = 240* 106* P

nD*B *R HERE n = 10 B = 600 N/mm2

D = 888 mm SO:

db = 240* 106 *8550 10 *888* 600 *92

= 64.7 mm WE TAKE 80 mm.

4.2 BOLTS FOR FLANGE BETWEEN INTERMEDIATE SHAFT AND SCREW SHAFT db = 240* 106* P nD*B *R HERE: n = 10 B = 600 N/mm2

D = 780 mm

SO:

db = 240* 106 *8550

10 *780* 600 *92

=69.04 mm

WE TAKE 80 mm.

5. COUPLINGS5.1 THICKNESS OF FLANGE5.1.1 INTERMEDIATE SHAFT FLANGE T 0.2 * dmin

HERE dmin = 409 mm SO: T 0.2 * 409 = 81.8 mm WE TAKE 115 mm

5.1.2 SCREW SHAFT FLANGE T 0.2 * dp rear

dp rear = 499 mm SO: T 0.2 *499 = 99.8 mm WE TAKE 135 mm

5.2 FILLET RADIUS5.2.1 INTERMEDIATE SHAFT FLANGE R 0.08*dmin
