The invention discloses a cam type straight wing paddle propeller with an adjustable cam direction angle, which comprises a propeller rotation box, a propeller driving assembly and a blade swing rod assembly, and further comprises a cam direction angle adjusting assembly, and the propeller driving assembly and the blade swing rod assembly are arranged on the propeller rotation box; comprising a cam shaft, a plane disc groove cam, a worm shaft and a worm shaft mounting seat, a worm gear is mounted at the top of the cam shaft, a worm gear pressing plate is mounted on the upper portion of the worm gear, the plane disc groove cam is mounted at the bottom of the cam shaft and located in a propeller rotation box, and the worm shaft mounting seat is mounted on a propeller mounting plate. And the worm shaft is mounted between the two worm shaft mounting seats and is matched with the worm gear. The worm shaft drives the worm wheel and the plane disc groove cam fixedly connected with the worm wheel through the cam shaft to rotate, and therefore the direction angle of the cam is changed. And meanwhile, a rotating plate and a box body of the conventional propeller are integrated, so that a rotating gap between the rotating plate and the box body of the propeller is eliminated.
本发明公开了一种凸轮方向角可调的凸轮式直翼桨推进器,包括推进器回转箱、推进器驱动组件和叶片摆杆组件,推进器驱动组件、叶片摆杆组件安装于推进器回转箱,还包括凸轮方向角调整组件,包括凸轮轴、平面盘型沟槽凸轮、蜗杆轴、蜗杆轴安装座,凸轮轴顶部安装蜗轮,蜗轮上部安装蜗轮压板,凸轮轴底部安装平面盘型沟槽凸轮,平面盘型沟槽凸轮位于推进器回转箱内部,蜗杆轴安装座安装于推进器安装板,蜗杆轴安装于两蜗杆轴安装座之间,蜗杆轴与蜗轮配合。本发明蜗杆轴带动蜗轮以及通过凸轮轴和蜗轮固定连接的平面盘型沟槽凸轮转动,从而改变凸轮方向角。同时将现有推进器回转板和箱体一体化,消除了推进器回转板和箱体之间存在的转动间隙。
