一、曲轴线工艺简介曲轴是引擎的主要旋转机件,装上连杆后,可承接连杆的往复运动变成循环运动,是发动机的重要机件。其有两个重要部位:主轴颈和连杆颈,主轴颈安装在汽缸体曲轴孔上,连杆颈与连杆大头孔连接,连杆小头孔与汽缸体活塞连接,是一个典型的曲柄滑块机构。曲轴的旋转是发动机乃至整个机械系统的原动力,如图1所示。
First, the crankshaft Process Overview Crankshaft is the engine of the main rotating parts, fitted with connecting rod, connecting rod can undertake the reciprocating motion into a circular motion, is the engine of the important parts. There are two important parts: the main journal and the connecting rod neck, the main journal is installed on the crankshaft hole of the cylinder block, the connecting rod neck is connected with the big hole of the connecting rod, the small hole of the connecting rod is connected with the piston of the cylinder block, and is a typical crank Slider mechanism. The rotation of the crankshaft is the driving force of the engine and even the entire mechanical system, as shown in Figure 1.
