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.
摘要翻译: 用于需要每个曲柄销(18)上的密封盘(22)的二冲程发动机的曲轴(10)通过在没有密封盘(22)的情况下进行锻造,加工和热处理而形成,然后施加两部分密封盘 (22)连接到每个曲柄销(18)。 密封盘(22)的两个部分具有与曲柄销(18)的中心一致的配合接口(35),并且每个部分中的半圆形凹部(34)围绕曲柄销(18)的一半。 这些部件的尺寸被设计成当以足够的力组装时对曲柄销(18)进行过盈配合。 这些部件通过激光焊接,螺栓或粘合剂固定在一起。 在焊接的情况下,部件通过垂直于接口(35)的榫钉(38)组装,以在焊接过程中保持正确的对准并加强最终组件的强度。
