背景技术
现有的无人机变速装置在使用的时候仍然存在一些缺陷,现有的无人机变速装置在使用时虽然能够完成变速操作,但是现有的无人机变速装置仅仅依靠改变发动机的转速来实现变速,这样变速的范围就比较小,而且变速不够的精确,会导致无人机不能完成不同条件下的飞行任务。
发明内容
本发明主要是解决现有技术所存在的技术问题,从而提供一种用于无人机螺旋桨的变速装置。
本发明的上述技术问题主要是通过下述技术方案得以解决的:
一种用于无人机螺旋桨的变速装置,所述的变速装置包含一水平设置的转轴,所述的转轴的一端焊接一挡板,所述的挡板一侧设置一外壳,所述的外壳的一侧设有若干圆孔,所述的外壳的顶部焊接一底座,所述的外壳的内部设有一第一齿轮,所述的第一齿轮的一侧设有第二齿轮,所述的第二齿轮的一侧设有第三齿轮,所述的第一齿轮、所述的第二齿轮和所述的第三齿轮一侧均卡接一第四齿轮,所述的第四齿轮的一侧设有一第一传动杆,所述的第一传动杆的外部套设一固定座,所述的固定座的一侧设有一第一电机箱,所述的第一电机箱的上方卡接一第二电机箱,所述的第二电机箱的一侧卡接一第三电机箱,所述的第二电机箱的一端安装一第二传动杆,所述的第三电机箱的一端安装一第三传动杆。

作为本发明较佳的实施例,所述的第一电机箱、所述的第二电机箱和所述的第三电机箱之间呈电性连接。
本发明的变速装置具有以下优点:使用者通过底座将整个装置固定,如果需要比较低的转速就接通第一电机箱,此时第一电机箱带动第一传动杆转动,从而利用第四齿轮带动第一齿轮旋转就可以实现螺旋桨较低的转动速度,如果需要中等转速就接通第三机箱,如果需要比较高的转速就接通第二机箱,第四齿轮分别带动第二齿轮和第三齿轮转动,从而实现螺旋桨的转速调整。利用第一齿轮、第二齿轮和第三齿轮的直径不同,能有效调节螺旋桨转速,效果明显。该变速装置结构简单,效果明显,成本低廉,实用性强。
