摘要
采用数学解析法推导出变桨驱动力矩M是与液压缸活塞承压面积A、变桨机构回转半径r、中心距a、液压缸安装距L min四重自变量以及桨距角θ有关的函数,结合变桨载荷对变桨机构进行优化设计,并对关键零部件进行强度分析。
The mathematical analysis method is used to deduce that the variable propeller driving torque M is a function related to cylinder piston bearing area A,revolving radius r,center distance a,cylinder installation distance L min and pitch angleθ.The variable propeller load is used to optimize the variable propeller mechanism,and the strength of the key components is analyzed.
