简介:0引言曲轴-这是内燃机的主要零件之一,它关系到内燃机的工作能力和可靠性.曲轴的主要质量参数是制造精度(用尺寸误差以及表面的形状误差和位置误差决定)和轴颈工作表面的粗糙度.对曲轴的几何精度和表面质量的主要要求是:1)主轴颈和连杆轴颈的直径精度6~7级;圆度偏差4~5级精度;2)主轴颈相对曲轴轴线的跳动,对直径达100mm的轴颈不大于0.01~0.015mm,对较大直径的轴颈不大于0.015~0.025mm.连杆轴颈相对自身轴线的允许跳动量大约较主轴颈的跳动量大50%;3)曲轴半径的长度偏差不大于±0.15mm/100mm;曲拐之间的角度差在曲轴全长上不大于±30;4)飞轮紧固法兰的端面跳动不大于0.005mm/100mm;轴颈圆柱表面的粗糙度Ra≤0.63μm.
简介:近日,沈阳机床集团收购西安交通大学产业(集团)总公司持有的交大昆机科技股份有限公司(即原昆明机床厂)股权签字仪式在西安举行,这表明沈阳机床已成为交大昆机科技股份有限公司第一大股东(持股比例为29%)。
