Description

软管泵转子
技术领域
本发明涉及软管泵，具体讲就是软管泵转子的改进结构。
背景技术
现有技术中的软管泵广泛使用在化工等工业领域，其基本结构包括壳体和置于壳体内的软管，由主轴驱动转动的转子支架带动滚轮挤压软管来泵送介质，在工作过程中辊轮滚压软管程度即软管的变形量有特殊要求，这与泵送流量、软管材质密切相关，这就要求辊轮在径向方向上能够移位调整，确保软管的被挤压程度；另外，在使用前期、中期及后期，由于软管的弹性会发生变化，能否调节辊轮在径向位置以获得辊轮滚压软管的适当性，这是业界迫切需要解决的技术问题。
发明内容
本发明的目的是提供一种软管泵转子，方便调节辊轮在径向方向上位置使得软管的被挤压程度适度。
为实现上述目的，本发明采用了以下技术方案：一种软管泵转子，主转轴包括固定连接的主轴和转子座，辊轮支架臂对称布置在转子座上且外端连接辊轮，辊轮轴芯与主轴的轴芯平行，辊轮支架臂与转子座之间构成沿径向位移的限位配合，辊轮支架臂与转子座之间由锁紧部件固连。
由于采用了上述技术方案，辊轮支架臂在转子座上可以沿径向方向位移并由锁紧 部件实施锁紧实现固定，这样就可以在需要的时候，调节辊轮支架臂的位置，也就是调节了辊轮与软管的配合位置，这样可以确保辊轮给予软管的力度，保证软管的正常工作。
附图说明
图1是本发明的主视图；
图2是图1的右视图；
图3是本发明的立体图；
图4分别是本发明的主轴转子座的立体图；
图5分别是本发明的辊轮支架臂的立体图。
具体实施方式
图1-5所示的软管泵转子中，主转轴包括固定连接的主轴10和转子座20，辊轮支架臂40对称布置在转子座20上且外端连接辊轮30，辊轮30轴芯与主轴10的轴芯平行，辊轮支架臂40与转子座20之间构成沿径向位移的限位配合，辊轮支架臂40与转子座20之间由锁紧部件固连。上述方案中，所谓的沿径向位移的限位配合是指在径向方向上辊轮支架臂40与 转子座20彼此可以相对移动，并且只能沿该确定径向方向移动。
主轴10和转子座20可以采取分体结构的形式独立加工在固连为一体，电机驱动主轴10转动，转子座20随之同步转动并带动其上连接的辊轮支架臂40及辊轮30转动，辊轮30转动时间歇式接触、辊压软管实现泵送介质的任务。由于辊轮支架臂40与转子座20之间构成沿径向位移的限位配合，所以可以根据需要调节辊轮30沿转子径向实施位移调节，从而保证辊轮30辊压软管的力度，使软管正常工作状态下的泵送效率，这样可以提高软管的使用寿命。
作为优选方案，转子座20由底板21及其两相对边设置的侧板22围成的槽型，所述的底板21与主轴10固连，所述的转子座20上的槽腔的槽长方向与主轴10的径向方向一致。该方案中选优槽型结构作为限位配合的导向约束，不仅结构简单，更有利装配操作。
辊轮支架臂40的里段位于转子座20的槽型腔内且两者构成径向移动的配合，辊轮支架臂40与转子座20的底板21和/或侧板22之间设置连接螺栓50构成锁紧部件，辊轮支架臂40的外端位于转子座20的槽型腔的外端外部。当调节辊轮支架臂40处于适当的位置后由连接螺栓50锁紧固连，确保了辊轮30的位置稳定。
具体的优选方案是，所述的辊轮支架臂40为条板状，辊轮支架臂40的内侧板面与底板21的腔内板面贴合，辊轮支架臂40的两侧板面与转子座20的侧板22的腔内板面贴合，辊轮支架臂40的板面上开设条形孔41，该条形孔41的长度方向与径向一致，底板21的板面上开设连接孔211，条形孔41与连接孔211位置对应且供连接螺栓50连接。
上述方案中，辊轮支架臂40与转子座20的槽底、槽壁均构成贴合配合即两者之间为三面接触式限位配合，留出径向方向的移动调节，保证了转子的动平衡的实现。
作为优选方案，两辊轮支架臂40以主轴10为中心对称布置，辊轮支架臂40的外侧板面上设置凸块42，两辊轮支架臂40上的凸块42之间设置调节丝杆60。上述方案是以辊轮支架臂40上限位槽为直槽为前提的，这样既方便加工又方便调节，尤其是设置凸块42来布 置丝杆60可以让丝杆60与螺栓50的栓头处在避让位置且可以实现辊轮支架臂40之间间距 的无级调节，实现最佳的辊轮30辊压软管的力度。
作为优选方案，每个辊轮支架臂40的板面上的条形孔41间隔布置三个，连接孔211对应条形孔41设置。
辊轮支架臂40上的凸块42沿板宽方向间隔布置两个，位于同侧的辊轮支架臂40上 的凸块42之间设置有一个调节丝杆60。这样可以保证两辊轮支架臂40相对于转子轴芯且沿径向同步靠近或远离，确保了所有辊轮30辊压软管的力度相同，即保证了介质泵送的流量的稳定性，避免了软管受到的辊压力度波动，进而确保软管的变形量稳定、可控。
为了方便装配和调节，转子座20的侧板22位于槽口处的边沿上设置标尺221，凸块42上有标记刻度421，凸块42上的标记刻度421也可以是凸台台面本身构成，标尺221与标记 刻度421临近对应布置。上述标尺221和标记刻度421的对应设置，可以在软管泵装配时提供方便，即在将软管首先布置在泵壳内并将其管端加以固定，此时由于没有辊轮30的挤压，软管十分方便地就可以完成安装，无论是转子后安装还是先安装都将辊轮支架臂40首先调节到接近位置处，即辊轮30调节到安装初始位，在该安装初始位的辊轮30与软管无干涉或基本无干涉，待软管安装完毕后，再调节辊轮支架臂40在转子座20上的位置，并观察标尺221和标记刻度421的相应位置，即可方便地判断辊轮30是否到达设计位置。
