曲轴液压套合是近年来在造船工业中取代热压套合的一种新的套合形式,可简化曲轴制造和装配工序、降低成本、缩短制造周期,并为曲轴无余量套合开辟了新途径。本文除介绍了这种液压套合的作用与原理,及工艺特征外,还提出了有关设计、计算的方法,特别对曲轴液压套合与拆卸提供了一系列实践试验参数,可供设计及制造部门参考。 Crankshaft hydraulic sleeve is a new type of sleeve that replaces hot sleeve in the shipbuilding industry in recent years, which can simplify the process of crankshaft manufacture and assembly, reduce the cost, shorten the manufacturing cycle and open up new space for crankshaft without margin way. In addition to introducing the function and principle of this type of hydraulic sleeve and its technological features, this paper also presents some methods of design and calculation, and provides a series of practical test parameters for hydraulic sleeve and disassembly of crankshaft, which can be used for design and manufacture Departmental reference.
