Description

设有通流孔的沉没辊
技术领域
本发明涉及热镀锌技术领域，尤其是一种热镀锌装置上沉没辊。
背景技术
现有热镀锌装置上的沉没辊一般包括辊筒、两个辊轴、两个连接轴套，连接轴套为阶梯式结构，大端为法兰盘，辊筒两端止口孔套装在连接轴套法兰盘上，并固定连接；连接轴套小端套装在辊轴一端，并固定连接，这种沉没辊的主要缺陷在于：一是结构强度、刚性差；二是锌液无法从辊筒内腔中流通。
发明内容
本发明针对现有技术的不足，提供一种能显著提高结构强度、刚性，使用时能实现锌液从辊筒内腔中流通的设有通流孔的沉没辊。
本发明通过下述技术方案实现技术目标。
设有通流孔的沉没辊，包括辊筒、辊轴、两个连接轴套；所述连接轴套为阶梯式结构，大端为法兰盘；所述辊筒两端的止口孔套装在连接轴套法兰盘上，并固定连接；其改进之处在于：所述辊轴为轴向贯穿两个连接轴套内孔的整体式结构，与两个连接轴套固定连接；所述连接轴套法兰盘上均布若干周向布置、与辊筒内腔连通的轴向通孔。
上述结构中，所述辊筒止口孔、连接轴套法兰盘外圆周结合处外端部分别设有坡口，坡口内设有焊缝。
本发明与现有技术相比，具有以下积极效果：
1、辊轴为轴向贯穿两个连接轴套内孔的整体式结构，显著提高本发明强度和刚性。
2、连接轴套法兰盘上均布若干周向布置、与辊筒内腔连通的轴向通孔，使用时不仅能实现锌液从辊筒内腔中流通，而且由于轴向通孔在连接轴套法兰盘上周向布置，因此，使用时锌液从辊筒内腔中流通时不会产生径向作用力，因而不会对本发明的使用产生不利的影响。
3、辊筒止口孔、连接轴套法兰盘外圆周结合处外端部分别设有坡口，坡口内设有焊缝，能使辊筒、辊轴通过焊缝熔为一体，防止辊筒、辊轴使用时松动，同时进一步提高本发明结构强度、刚性。
附图说明
图1为本发明结构示意图。
图2为图1右视图。
具体实施方式
下面根据附图并结合实施例对本发明作进一步说明。
附图所示的设有通流孔的沉没辊，包括辊筒1、辊轴2、两个连接轴套3；连接轴套3为阶梯式结构，大端为法兰盘；辊筒1两端的止口孔套装在连接轴套3法兰盘上，并固定连接；辊轴2为轴向贯穿两个连接轴套3内孔的整体式结构，与两个连接轴套固定连接；连接轴套3法兰盘上均布若干（本实施例为6个）周向布置、与辊筒1内腔连通的轴向通孔3.1。
辊筒1止口孔、连接轴套3法兰盘外圆周结合处外端部分别设有坡口，坡口内设有焊缝。
