The invention discloses a connecting device for a front propeller and a rear propeller, the front end of a front propeller shaft extends in a fillet transition manner to form a flange plate, and the flange plate is fixed on the front propeller through a plurality of bolts and nuts fixed on the front propeller; a front paddle shaft roller path is machined in the middle of the front paddle shaft, aconnecting sleeve roller path is machined in an inner hole of the connecting sleeve, and ball roller path grooves A and ball roller path grooves B which are the same as the steel balls in number and are combined together to form a complete ball roller path groove of the steel balls are formed in the front paddle shaft roller path and the connecting sleeve roller path respectively. The connecting sleeve is rotatably assembled on the front paddle shaft through a plurality of steel balls positioned in the ball raceway grooves A and B; the pre-tightening nut is screwed and fixed at one end of thefront paddle shaft flange plate; and a flange plate is arranged at the rear end of the connecting sleeve and is fixed on the rear paddle through a plurality of screws. The supporting force on the front oar is large, the fixing effect is stable, and the risk that the front oar is separated from the rear oar is greatly reduced.

    本发明公开了一种前后桨连接装置,前桨轴前端圆角过渡延伸成法兰盘,该法兰盘通过固定在前桨上的多个螺栓和螺母固定在前桨上;前桨轴中部加工有前桨轴滚道,连接套内孔加工有连接套滚道,前桨轴滚道和连接套滚道上分别有与钢球个数相同的合在一起形成钢球一个完整滚珠滚道槽的滚珠滚道槽A和滚珠滚道槽B;连接套通过位于滚珠滚道槽A和B内的多个钢球可旋转地装配在前桨轴上;预紧螺母螺纹拧紧固定在前桨轴法兰盘一端;连接套后端为一法兰盘,该法兰盘通过多个螺钉固定在后桨上。本发明对前桨的支撑力度大,固定效果稳固,大大减少了前桨脱离后桨的风险。
