补充资料:轧辊名义直径
轧辊名义直径
nominal diameter of roll
zhagun mingyi Zhi】ing轧辊名义直径(nominal diameter of roll)型材轧机传动乳棍的人字齿轮节圆直径。型材轧机往往由数个机列组成,每列轧机的乳棍原始直径各不相同。而每架轧机由于孔型磨损后要重新车辊,轧辊直径则由大变小,因此需以不受轧辊重车影响的轧辊名义直径,即固定不变的人字齿轮节圆直径D。来给型材轧机命名。对一架或一列轧机而言,轧辊名义直径就是本架或本列轧机人字齿轮节圆直径。而对多列轧机而言,轧机的名义直径是指成品轧机或机列的人字齿轮节圆直径,如庐250线材轧机、笋850轨梁轧机等。有时也以开坯轧机和成品轧机人字齿轮节圆直径来共同表示,如笋400净250轧机、笋650净500轧机等,有时还加上具体架数,如笋500 xl邝350 x3,表示轧机由一架价500轧机和3架必35。轧机组成的二列式轧机。 (胡抹)
