The invention relates to the field of ship driving devices, and discloses a contra-rotating propeller driving device driven by a magnetic bearing rim type motor, the contra-rotating propeller driving device comprises a protective shell, a forward rotating rim type motor is arranged in the protective shell, and the output end of the forward rotating rim type motor is fixedly connected with a forward rotating propeller; a reverse rotation wheel flange type motor is arranged on one side of the forward rotation wheel flange type motor, the output end of the reverse rotation wheel flange type motor is fixedly connected with a reverse rotation propeller, and magnetic thrust bearings are arranged on the two sides of the forward rotation wheel flange type motor and the two sides of the reverse rotation wheel flange type motor. According to the contra-rotating propeller, through the design that the propellers are arranged in series front and back, the propellers arranged front and back are mutually independent, a shaft system structure needed by a traditional contra-rotating propeller is omitted, the sealing problem and high production cost existing in the traditional contra-rotating propeller are fundamentally solved, a shaft system and a high-precision machining and assembling technology are omitted, the production cost is reduced, and the production efficiency is improved. And the reliability of the contra-rotating propellers is greatly improved, and the overall propelling efficiency and thrust are improved.
本发明涉及船舶驱动装置领域,公开了一种磁轴承轮缘式电机驱动的对转螺旋桨驱动装置,包括保护壳,所述保护壳内部设置有正转轮缘式电机,所述正转轮缘式电机输出端固定连接有正转螺旋桨,所述正转轮缘式电机一侧设置有反转轮缘式电机,所述反转轮缘式电机输出端固定连接有反转螺旋桨,所述正转轮缘式电机与所述反转轮缘式电机两侧均设置有磁推力轴承。通过一前一后串列式的螺旋桨设计,前后布置的螺旋桨互相独立,取消了传统对转桨所需的轴系结构,从根本上消除了以往对转桨存在的密封问题和高昂的生产成本,取消轴系和高精度的加工与装配工艺,不仅降低了生产成本,还大大提高了对转桨的可靠性提高了整体推进效率和推力。
