卷筒槽形 |
|||||||||
|
卷筒槽形分为标准槽形和加深槽形两种。槽形表面粗糙度分为两级:1级Ra6.3μm;2级Ra12.5μm
标记示例: 卷筒槽形的槽底半径R=10 mm,槽距P1=20 mm,表面粗糙度为1级的标准槽形,标记为: 槽 形 10×20-1 JB/T 9006.1—1999 卷筒槽形的槽底半径R=10 mm,槽距P2=24 mm,表面粗糙度为2级的加深槽形,标记为: 深槽形 10×24-2 JB/T 9006.1—1999 mm |

注:1.本标准规定的槽形除多层缠绕和电动葫芦用卷筒外,适用于所有起重机的钢丝绳铸造卷筒和焊接卷筒。 2.本标准的槽底半径 R 是以钢丝绳直径 d 的最大允许偏差为+7%确定的。钢丝绳绕进或绕出卷筒时,其偏离螺旋槽每一侧的角度应不大于4°。 |
