中小型内燃机连杆螺栓孔加工超差的研究

PRELIMINARY STUDY ON MACHINING ERRORS QVERFLOWING OF BOLT-HOLES ON CONNECTING-ROD IN MODERATE AND SMALL TYPE INTERNAL-COMBUSTION ENGINE

本文对我国中小型内燃机连杆螺栓孔加工中的相互位置精度超差问题,通过典型实例作了较深入的分析和必要的计算,并提出了改进措施,借以提高加工质量。

To the problem that relative-position error goes out beyond the limit in machining bolt-holes which was shaped on the connecting- rod in our country's moderate and small internal combustion engine, this paper,by means of studing a typical instance,gives out more deepgoing analysis and necessary calculation,and put out some mea- sures for improving the product quality.
