实施例1
如图1和图2所示，本实施例中的摇头装置100具体为塔扇摇头装置100，应用于塔扇运行中的摇头过程，主要包括：固定组件、转动组件、驱动组件50以及设置在固定组件与转动组件之间的滚动体组件。
具体地，固定组件与塔扇的基座部分连接，转动组件可转动地安装在固定组件上；驱动组件50安装在转动组件上并可驱动转动组件相对固定组件上往复转动；滚动体组件设置在固定组件与转动组件之间，且分别与固定组件和转动组件滚动配合，从而本实施例中的摇头装置100通过在固定组件和转动组件之间设置滚动体组件，固定组件与转动组件之间的转动配合通过转动组件与滚动体组件转动配合、固定组件与滚动体组件滚动配合实现，配合过程中接触方式为点接触或者线接触，塔扇的摇头过程更加的顺畅和稳定，相对于现有技术中采用两锥面配合方式，无需在固定组件和转动组件的零件上加工锥面，避免了由此导致的制造装配难度大的问题，无需控制较高的加工精度，避免了塔扇整机的晃动，整机稳定性不够的问题。
具体地，对于本实施例中的滚动体组件，滚动体组件具体为球体组件，球体组件包括球体保持架和设置在球体保持架上的球体，固定组件与转动组件之间通过球体组件实现摇头过程的顺畅和稳定。
优选地，球体保持架设有球槽，球槽的开口处的直径略小于球体的直径，从而可以避免球体从球槽中脱出，球体组件的稳定性更好，球槽的中部处的直径略大于球体的直径，从而球体组件在滚动过程中更加的顺畅。
球体组件更具体钢球组件70，钢球组件70包括钢球保持架71及钢球73，钢球73容纳在钢球槽711中，进而摇头装置100在要求过程中，除了转动顺畅，固定组件与转动组件之间连接处的刚度也更好，改善了塔扇在搬运过程、摇头等过程中因固定组件与转动组件刚度不足的问题导致的晃动问题。同时由于钢球73的刚性特性，钢球73的弹性形变较小，因此塔扇的刚度更好，不易发生倾斜，稳定性更好。钢球组件70具体是通过卡扣固定在固定组件中的固定座10上，在转动组件相对于固定组件转动过程中，钢球保持架71固定，钢球73在钢球槽711中滚动。
当然，滚动体组件除了采用球体组件，也可以是在滚柱组件，通过呈主体的滚柱在固定组件和转动组件之间运动，同样能够实现本发明的目的。
优选地，摇头装置100还包括设置在固定组件上用于与滚动体组件配合的第一滚道11， 以及设置在转动组件上用于与滚动体组件配合的第二滚道31，在转动组件相对于固定组件转动过程中，滚动体组件中的滚动体容纳在第一滚道11和第二滚道31中，从而在摇头过程中转动组件的平稳度更好。
优选地，第一滚道11和/或第二滚道31上设置有与滚动体组件抵接的耐磨环13，耐磨环13采用聚甲醛一体成型，钢球73具体是和耐磨环13接触滚动，进而塔扇摇头过程中阻力小，使用寿命更长。
对于固定组件、转动组件以及驱动组件50如何固定，具体地，驱动组件50上设置有作为转动组件旋转中心轴线的转动轴511，固定组件上设置有与转动轴511配合的转动孔15，摇头装置100还包括安装在转动轴511上的作为限位件的卡簧91，对应的转动轴511上设有卡槽，限位件为卡入转动轴511上的卡槽，具体容纳在固定座10的卡簧槽16中，在转动轴511穿过转动孔15后，卡簧91被安装在转动轴511上与固定组件抵接限位。
优选地，摇头装置100还包括轴承件93，且轴承件93设置在转动轴511远离转动组件的一端，具体安装在固定座10的轴承槽17内，轴承件93与转动轴511之间配合时的间隙可以做的很小，从而在转动组件转动过程中，可以减小塔扇整机的晃动。
优选地，转动轴511为管状轴，其上设置有供塔扇中电源线通过的通孔，进而可以利用通孔，简化塔扇的内部结构。
具体地，对于转动组件如何在驱动组件50的驱动下往复摆动，具体转动组件包括转动座30，以及底板51，转动轴511设置在底板51上。驱动组件50包括：电机支架52，安装在转动座30上并可随转动座30转动而转动；电机53，通过螺钉安装在电机支架52上，并具有输出动力的电机输出轴531；曲柄54，曲柄54固定于电机输出轴531，摇杆55，摇杆55套入转动轴511，并与固定座10固定连接；连杆56，连杆56的一端与曲柄54连接，另一端与摇杆55连接；这样曲柄54、摇杆55、连杆56形成四连杆56机构，在电机53的驱动下，摇杆55绕转动轴511往复转动，进而带动转动组件往复转动。
本实施例还提供一种塔扇，包括塔扇摇头装置100，塔扇摇头装置100为如上的塔扇摇头装置100，进而塔扇具有稳定性良好的优点。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
