具体到本实施方式中，安装座150包括第一安装部及第二安装部，第一安装部与第二安装部分别套设于内轴110的外壁以围成套设于内轴110上的安装座150。例如，先可以一体成型的制造出安装座150，然后将安装座150一分为二，分别为第一安装部及第二安装部，然后分别将第一安装部与第二安装部固定于齿轮300上。
具体到本实施方式中，轴套160包括第一轴套部161及第二轴套部162，第一轴套部161固定于第一安装部上，第二轴套部162固定于第二安装部上，第一轴套部161与第二轴套部162分别套设于内轴110的外壁以围成套设于内轴110上的轴套160。例如，先可以一体成型的制造出轴套160，然后将轴套160一分为二，分别为第一轴套部161及第二轴套部162，然后分别将第一轴套部161与第二轴套部162固定于第一安装部与第二安装部上。轴套160可以为塑料材质制成。
由于轴套160位于内轴110靠近防转装置200的一端，因此轴套160承受的防转装置200和外接管路(例如20，40和60)的力更大，因此轴套160相对于内轴110远离防转装置200那端的轴承140来说更容易损坏。因此需要将轴套160设置成容易快速更换的结构，以提高工作效率。所以通过将轴套160一分为二的结构套设于内轴110上，当轴套160受损后，可以快速更换轴套160。
上述旋转式液体灌装机10及其分配器100至少具有以下优点：
在内轴110靠近防转装置200的一端套设安装座150及轴套160，且安装座150及轴套160可绕内轴110转动，因此当外壳120相对于内轴110转动时，位于内轴110的外壁与外壳120的内壁之间的轴承140与位于安装座150与内轴110的外壁之间的轴套160形成双轴承导向结构，可以有效抵消防转装置200和外接管路施加在内轴110上的力，消除轴承140的过载，延缓导向密封件130 的磨损和失效，延长分配器100的使用寿命，从而提高集气效率，消除产品的质量风险。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
