曲轴斜油孔钻削头设计

Design of the Drilling Head Using in Oblique Oilhole of Crank

曲轴的各轴颈在很高的比压下作高速旋转运动 ,使轴颈和轴承受到强烈磨擦。为保证曲轴轴承工作可靠 ,曲轴上必须设置可靠的润滑油道 ,将润滑油送到轴承磨擦表面上去。此油道属细长孔 ,且于轴线成一定的角度。本文介绍的是一种曲轴斜油孔钻削头的设计、结构和原理等 ,动用了两个电磁离合器 ,使得一根钻削头在工作时 ,另一根钻削头停止旋转 ,避免不必要的空转功率消耗 ;该设备用于生产后 ,实践证明 ,运行可靠 ,操作方便 。

Because the shaft necks whirligig with high speed under high pressure, the shaft necks and bearings endure intense attrition. To ensure the bearing work reliably, must be set up to deliver lubicrant to the bearing surface. The lubricative path is a slightness hole which is oblique to the crank. This paper introduced the design, structure and principle of a drilling head using in crank's oblique oilhole. Two electromagnetic clutches are used to make a drilling head stop when another drilling head working, thus it can avoid power consume when racing. This facilityruns reliable with convenience operation, can satisfy the practical manufacture.
