V型柴油机凸轮轴轴承孔镗孔研究

Boring Camshaft Bearing Hole of V-type Diesel Engine

V型柴油机结构比较复杂,凸轮轴轴承孔加工难度大。本文以某V型两列8缸机为例,对凸轮轴轴承孔加工工艺及镗孔装置设计进行研究,提出了凸轮轴轴承孔加工方法及镗杆装置的设计方案,实现了凸轮轴轴承孔切削加工。还介绍了本加工技术在实际应用中的难点及解决方法,可供V型柴油机凸轮轴轴承孔加工或类似箱体轴承孔加工参考。

Boring the camshaft bearing hole of the complex V-type diesel engine is difficult.In this paper,the boring technology and boring device of camshaft bearing hole of the two-row eight-cylinder V-type diesel engine are studied,the boring method and the design of boring device of the camshaft bearing hole are put forward and the boring of the camshaft bearing hole is realized.The difficulties and solutions in the practical application of the boring technology are also introduced.It can be used as reference for boring bearing holes of V-type diesel engine camshaft or similar box bearing holes.
