The invention relates to a rudderstock in a multi-pyramid connection mode, the cross section of any position where the rudderstock is connected with a tiller or a rudderstock bearing seat is a regular polygon, the rudderstock is installed in the rudderstock bearing seat and/or the tiller, and a through hole used for containing the rudderstock is formed in the rudderstock bearing seat and/or the tiller. And the sectional area of the part of the rudderstock, which is arranged on the rudderstock bearing seat and/or the rudderstock, is changed. After the rudderstock is inserted into the rudderstock bearing seat and/or the rudderstock, torque between the rudderstock and the rudderstock bearing seat and/or the rudderstock is transmitted through the polygonal pyramid, the torque is mainly borne through friction force and four-side pressure, compared with a traditional cone which is only borne by the friction force, the surface pressure bearing part is increased, and then the friction force component is reduced; the press-in amount is reduced, the press-fitting difficulty is reduced, the key connection design is omitted, and the manufacturing time is shortened.
本发明涉及一种多菱锥连接形式舵杆,舵杆与舵柄或舵杆承座连接的任一处的横截面均为规则多边形,所述舵杆安装在舵杆承座和/或舵柄中,所述舵杆承座和/或舵柄内部开设用于容纳舵杆的通孔,所述舵杆设置于舵杆承座和/或舵柄的部分的截面积变化。本发明舵杆插入至舵杆承座和/或舵柄后,当舵杆与舵杆承座和/或舵柄之间的扭矩传递将通过多棱锥传递,其主要是通过摩擦力及四面压力承受扭矩,相较传统的圆锥形只由摩擦力承受,多了面压承受部分,进而减少了摩擦力成分,减少压入量、降低压装难度、免去键连接设计、降低制造工时。
