The invention provides a propulsion system of coaxial contra-rotating propellers and an installation method of the propulsion system. The propelling system comprises a first propelling motor, a second propelling motor, an outer side shaft system and an inner side shaft system. The second propulsion motor is hollow; the outer side tail shaft and the outer side middle shaft are hollow shafts; the inner side tail shaft and the inner side middle shaft are solid shafts; the inner side tail shaft is coaxially inserted into the outer side tail shaft, and the inner side middle shaft is coaxially inserted into the outer side middle shaft. The second propulsion motor is arranged to be in a shaft-driven hollow form, and the outer side tail shaft and the outer side middle shaft are both arranged to be hollow shafts, so that the front side propeller and the rear side propeller can be arranged in a contra-rotating mode. And the outer side shaft system and the inner side shaft system are coaxially arranged, so that the problem of power limitation caused by vertical arrangement of a propulsion motor and the shaft systems in the prior art is solved, high-power operation of the coaxial contra-rotating propeller propulsion system is realized, and the coaxial contra-rotating propeller propulsion system is energy-saving, environment-friendly and beneficial to popularization and use.

    本申请提供一种共轴对转螺旋桨的推进系统及其安装方法。所述推进系统包括第一推进电机、第二推进电机、外侧轴系、内侧轴系。第二推进电机空心设置;外侧艉轴和外侧中间轴均为空心轴;内侧艉轴和内侧中间轴均为实心轴;且内侧艉轴同轴插设于外侧艉轴内,内侧中间轴同轴插设于外侧中间轴内。本申请通过将第二推进电机设为轴发转发空心形式,并且将外侧艉轴和外侧中间轴均设为空心轴,能够实现将前侧螺旋桨、后侧螺旋桨对转设置。并且将外侧轴系与内侧轴系同轴设置,解决了现有技术中推进电机与轴系垂直设置造成的功率限制问题,实现共轴对转螺旋桨的推进系统的大功率运行,并且节能环保,利于推广使用。
