    发动机缸体曲轴加工工艺特点
    2016-8-11 14:23:13
    曲轴在发动机缸体曲轴孔内高速旋转运动,通过轴瓦与曲轴孔之间形成油膜,支撑和润滑高速旋转的曲轴,这对曲轴孔精加工后的精度提出了较高的要求。
    Crankshaft in engine crankcase bore high-speed rotation movement, between bearing and shaft hole through the formation of oil film, support and lubrication of high speed rotating crankshaft, which on crankshaft hole machining accuracy of proposed higher requirements.
    目前,曲轴孔精加工主要有两种方法:一是精镗加工,二是铰琦加工,两种方法各有优劣,根据企业实际情况,本文选择精镗作为曲轴孔的精加工方法.设计曲轴
    At present, there are two methods in the crankshaft hole machining: fine boring processing, the second is explored the hinge processing, two methods have their own advantages and disadvantages, according to the actual situation of the enterprise, this paper chooses fine boring as finishing methods of the bore of the crankshaft. The crankshaft design
    孔精镗专用镗床。要使发动机工作时曲轴运转平稳,振动和噪声小,零件寿命长,曲轴必须具有较高的旋转精度。要得到较高的旋转精度,除要求曲轴自身具
    The hole on the special boring machine. To make the engine running smoothly, vibration and noise of small, long life, the crankshaft must have a high rotation accuracy. To obtain a higher rotation accuracy, the crankshaft itself is required.
    有较高的动平衡外,还要求与其配合的曲轴孔具有较高的加工精度,而合理的工艺及先进的加工设备是工件能得到高精度的重要保证。
    There is a high dynamic balance, but also requires the crankshaft hole with its high machining accuracy, and the reasonable process and advanced processing equipment is the workpiece can be an important guarantee of high accuracy.
