The utility model relates to a supporting roller bearing seat for a leveller, which is convenient for maintenance and disassembly and assembly, and belongs to the technical field of supporting rollers for pulling straightener. Its technical scheme is that it consists of bearing seats on the support roll and the bearing seats under the support roll. The bearing seats on the support rolls and the bearing seats under the support roll have two semicircular axis holes of the same diameter, respectively, which constitute two complete shaft holes of the support roll respectively. The diameter of the two support rolls is matched with the diameter of the support roll and supports the upper shaft of the roller. The two ends of the lower bearing seat of the bearing seat and the supporting roller are respectively provided with relative mounting holes for bearing blocks, and are fixed by fixed bolts. The utility model has the advantages of simple structure and convenient use. It can disassemble the bearing seat of the damaged support roller, avoid disassembling and assembling other bearing pedestal, realize the rapid disassembly and maintenance of the support roller of the pull straightener, reduce the accident rate by 90%, reduce the disassembly efficiency of each support roll from the original 48 hours to 8 hours, and be suitable for cold. Rolling production line popularization and application.

一种便于维修拆装的拉矫机支撑辊轴承座
本技术涉及一种在拉矫机支撑辊需要维修时方便拆装的支撑辊轴承座,属于拉矫机支撑辊设备
技术介绍
拉矫机是轧钢生产过程中关键设备,用来改善热轧带钢板形,消除带钢浪形、瓢曲等板形缺陷,提高带钢的平直度和板形质量,同时提高热轧带钢破磷效果,使板带表面氧化铁皮破碎,提高酸洗效率。拉矫机辊系结构由两套弯曲单元和一套矫直单元组成,共有五组辊盒,每一组辊盒由一支工作辊和两列共计9对(18支)支撑辊组成。由于支撑辊辊系是以两支辊为一组以串联的方式组成,如果辊系中间部位有损坏的支撑辊需要更换,受装配工艺所限,更换时只能从一侧依次拆卸,增加了工作量,降低了效率。在新辊回装时,需要新辊与旧轴承座要进行修磨、配装,无法保证达到工艺所要求的装配精度,使得支撑辊容易产生轴向位移,导致工作辊轴向窜动大,极易发生工作辊“抱死”现象,从而会造成冷轧生产过程的不稳定,给企业带来严重的经济损失。
技术实现思路
本技术所要解决的技术问题是提供一种便于维修拆装的拉矫机支撑辊轴承座,这种支撑辊轴承座可以快速、精准完成拉矫机支撑辊拆装,避免拉矫机支撑辊产生轴向位移,产生拉矫机工作辊轴向窜动的故障,进而避免发生工作辊“抱死”现象,保证生产的稳定进行。解决上述技术问题的技术方案是:一种便于维修拆装的拉矫机支撑辊轴承座,它由支撑辊上轴承座和支撑辊下轴承座组成,支撑辊上轴承座和支撑辊下轴承座分别有两个相同直径的半圆形轴孔,支撑辊上轴承座和支撑辊下轴承座的半圆形轴孔分别相对组成两个完整的支撑辊轴孔,支撑辊上轴承座和支撑辊下轴承座组成的两个支撑辊轴孔直径与支撑辊直径相匹配,支 ...
