The invention discloses a method for determining the initial zero position of keyless taper assembly of a propeller, which relates to the technical field of propeller assembly and manufacturing, and comprises the following steps of: firstly, measuring various parameters of a propeller hub and a propeller shaft, and calculating the tightening torque required by the initial zero position according to a formula; the propeller hub is placed in the bearing mechanism, and the propeller shaft is hoisted by the hoisting mechanism and moved to the position above the propeller hub to be aligned with the propeller hub taper hole; then the hoisting mechanism is loosened, so that the propeller shaft freely falls down and is inserted into the propeller hub taper hole; rotating torque is detected through a torque sensor, and it is judged that assembly reaches the initial zero position; according to the invention, the axial thrust is converted into the tightening torque of the end face gland bolt, so that the zero position of the taper sleeving push-in amount of the propeller of the steering oar device is quantified; the method is simple and easy to operate, the initial zero position of the push-in amount of the propeller is quantified through the rotating torque of the end face gland bolt, the contact face does not need to be observed repeatedly through Buddha matching, and therefore the safety and efficiency of propeller assembly are greatly improved.
本发明公开了一种螺旋桨无键锥度装配起始零位的确定方法,涉及螺旋桨装配制造技术领域,包括下列步骤:首先测量桨榖和桨轴的各项参数,并根据公式计算出起始零位所需拧紧力矩,将桨榖放入承托机构内利用吊装机构将桨轴起吊并移动至桨榖上方与桨榖锥孔位置对正;而后吊装机构松开,使桨轴自由下落插入桨榖锥孔内;通过扭矩传感器检测转动扭矩,判断装配到达起始零位;本发明将轴向推力转换成端面压盖螺栓的拧紧力矩,从而量化出舵桨装置螺旋桨锥度套合推入量零位;方法简单易于操作,通过端面压盖螺栓的旋转扭矩量化了螺旋桨推入量的起始零位,不需要反复去通过佛配观察接触面,从而大大地提高的螺旋桨装配的安全性和效率。
