The invention relates to the field of unmanned aerial vehicles, in particular to a multipurpose unmanned aerial vehicle and a method. The surfaces of an upper shaft fixing gear (108) and a lower shaft fixing gear (107) are respectively provided with a groove, and a roller of a roller bearing can move along the grooves, so that the operation of the upper shaft fixing gear (108), the lower shaft fixing gear (107) and the roller bearing is not influenced by each other, the grooves have a positioning function, and therefore, the upper rotating part and the lower rotating part of a helicopter can operate independently without interference.

    本发明涉及无人机领域,尤其涉及一种多用途无人机和方法。上方轴固定齿轮(108)和下方轴固定齿轮(107)的面上各自包含凹槽,滚子轴承的滚子能够顺着凹槽进行移动,进而实现上方轴固定齿轮(108)、下方轴固定齿轮(107)、滚子轴承彼此不影响进行运行且凹槽有定位作用,进而使得直升机的上转动部分和下转动部分彼此独立运行互不干扰。
