摘要：
A crankshaft (10) for a two-stroke engine requiring a seal disc (22) on each crank pin (18) is formed by forging, machining and heat treating without a seal disc (22) and then applying a two-part seal disc (22) to each crank pin (18). The two parts of the seal disc (22) have a mating interface (35) in line with the centre the crank pin (18) and a semi-circular recess (34) in each part surrounds half of the crank pin (18). The parts are dimensioned to effect an interference fit on the crank pin (18) when assembled with sufficient force. The parts are secured together by laser welding, bolts or by adhesive bonding. In the case of welding, the parts are assembled with dowels (38) normal to the interface (35) to maintain the proper alignment during welding and to reinforce the strength of the final assembly.
