一、概述随着国内外机械加工技术的发展,70年代后期圆锥过盈配合开始广泛地用于内燃机与车辆、轧钢机械、船帕机械等方面。由于圆锥过盈配合的定心性好、承载能力高、承受交变载荷和冲击载荷的性能好,又可避免零件强度由于切割键槽等原因而削弱。与圆柱形过盈配合相比,具有定位较正确及获得较正确的过盈(测量轴向过盈)的可能性,利用液压装拆时不需要很大的轴向力,配合面不易擦伤,可多次装拆,因此圆锥 I. Overview With the development of mechanical processing technology at home and abroad, the conical interference fit in the late 1970s is widely used in internal combustion engines and vehicles, rolling machinery, ship machinery and so on. Due to conical interference fit with good centering, high carrying capacity, to withstand the alternating load and impact load of good performance, but also to avoid the part strength due to cutting keyway and other reasons weakened. Compared with the cylindrical interference fit, with more accurate positioning and obtain the correct interference (axial interference measured) the possibility of hydraulic mounting and disassembly does not require a lot of axial force, the mating surface is not easy to scratch , Can be repeatedly disassembled, so conical
