Description

回转件组合装置及其连接轴 技术领域
本发明涉及一种多个回转件的组合装置，尤其是多个回转件之间圆周相对位置可调整的装置及其连接轴。
背景技术
在机械装置技术领域，很多装置会涉及到两个或多个回转件的组合装置在各回转件圆周方向上的相对位置调整，如偏心机构、齿轮系和轮轴等装置中的多个回转件在其圆周方向上的相对位置调整。现有技术中，两个或多个回转件在圆周方向的相对位置只能通过在回转件组合装置静止时手动调整并锁紧两个或者多个回转件的位置的方式进行调整。例如，专利号为200920308697.3、发明创造名称为“激振器”的中国实用新型专利说明书公开了一种激振器偏心量的调整方法：用扳手手动拧开紧固螺钉，调节两个偏心轮的周向相对位置，即调节好偏心量后，再紧固所述螺钉。这种回转件组合装置在圆周方向上的相对位置调整方式操作麻烦，不适合自动化控制。为了实现自动调节，北华航天工业学院段新豪等在《机械强度》2018年01期上发表的文章《偏心质量可调节惯性激振器设计与分析》一文中提到控制液体在回转体内的不匀均分布而产生偏心力。使用此种方式的缺点是各零部件要求不能有液体泄漏，制造精度要求高。同时液体密度普遍较小，为了产生较大激振力，需要较大的偏心质量，使得激振器体积较大。另外这种调整方式需要复杂的电气来控制，设备制造和运行成本高，并且调整激振力的精度不易保证。
发明内容
针对现有技术的不足，本发明提供一种适合自动化控制，结构简单，能够保证多个回转件之间圆周方向上相对位置调整精度的回转件组合装置。
回转件组合装置，至少包括第一回转件(1)和第二回转件(2)，还包括所述第一回转件(1)和所述第二回转件(2)的连接轴(3)，所述第一回转件(1)和所述第二回转件(2)中至少一个通过螺旋凹槽和与所述螺旋凹槽配合的凸台结构与所述连接轴(3)连接。
本发明提供的回转件组合装置，可以将所述第一回转件(1)和所述第二回转件(2)的轴向位置通过固定装置进行固定，此时只能调整所述第一回转件(1) 和所述第二回转件(2)两者之间的夹角，也就是圆周方向上的相对位置；也可以不将所述第一回转件(1)和所述第二回转件(2)的轴向位置通过固定装置进行固定，此时既可以调整所述第一回转件(1)和所述第二回转件(2)两者之间的夹角，也就是圆周方向上的相对位置；也可以同时调整所述第一回转件(1)和所述第二回转件(2)两者之间的轴向间隔，即轴向相对位置。
