宽厚板矫直机支承辊强度分析

Strength Analysis of Backup Roll of Plate Leveller

矫直辊具有长径比大的特点,辊子强度和刚度都很低,因此在矫直辊上配有多排支承辊用来增加强度和刚度。宽厚板矫直辊承受矫直力大,支承辊受到大的支反力作用,故在设计中需对支承辊的强度进行计算分析。

The straightening roller has the characteristics of large length diameter ratio,and its strength and stiffness are very low.Therefore,multiple rows of backup rolls are equipped on the straightening roll to increase the strength and stiffness.The straightening roller of wide and heavy plate bears large straightening force,while the backup roll is subjected to large supporting reaction force.It is necessary to calculate and analyze the strength of the backup roll in the design.
