四辊轧机工作辊轴向力分析与保险销断裂原因

运用材料力学、弹性理论对四辊可逆冷轧机辊系传动的受力和轧制过程轴向力进行分析,确定工作辊传动轴保险销时常断裂的主要原因是扭矩剪切力,而辊系虽然存在轴向力,但通过事先管理与严格现场操作是可以控制的.

Axial Force Analysis of the Working Roller of a Four roller Mill and the Causes of Safety Pin Damage

Based on mechanics of material and elastic theory,analysis is made to the stress on the roller transmission of a four roller reversing cold rolling mill and the axial force generated during the rolling process.The result shows that the main reason causing easy damage of the safety pin of the working roller driving shaft is the twist shearing force generated in working.Though the axial force exists in roller,yet it can be handled in advance and strictly controlled in site operation to avoid such damage.
