The invention belongs to the technical field of ship shaft generator load test, and discloses a propeller for test and a shaft generator load test method.The propeller for test is used for the load test of a shaft generator, the shaft generator is used for being connected to a shaft system of a ship, and the shaft system comprises an intermediate shaft and a tail shaft connected to the intermediate shaft; the shaft generator is connected to the intermediate shaft, the propeller shaft can be provided with a ship propeller or a propeller for testing, the propeller for testing comprises a propeller hub mounted on the propeller shaft and blades arranged on the propeller hub, and when the propeller hub rotates relative to the propeller shaft, the blades do not generate thrust in the front-back direction of the ship, so that before a load test of the shaft generator is carried out, the propeller is not pushed to the propeller hub; the ship propeller can be detached from the tail shaft and replaced with the propeller for testing, at the moment, when the main engine drives the middle shaft and the tail shaft to rotate, the propeller for testing does not generate thrust in the front-back direction of the ship, and therefore the ship body is kept static, a shaft generator load test can be conducted in a wharf, and wharf safety is not affected.
本发明属于船舶轴带发电机负荷试验技术领域,公开了试验用螺旋桨及轴带发电机负荷试验方法,试验用螺旋桨用于轴带发电机的负荷试验,轴带发电机用于连接在船舶的轴系,轴系包括中间轴和连接于中间轴的艉轴,轴带发电机连接于中间轴,艉轴能够安装船舶螺旋桨或试验用螺旋桨,试验用螺旋桨包括用于安装在艉轴的桨毂以及设置于桨毂的叶片,当桨毂相对于艉轴转动时,叶片不产生沿船舶前后方向的推力,从而在进行轴带发电机负荷试验前,可将船舶螺旋桨从艉轴拆下并换上试验用螺旋桨,此时主机带动中间轴以及艉轴转动时,试验用螺旋桨不会产生沿船舶前后方向的推力,从而使船体保持静止,可在码头中进行轴带发电机负荷试验,且不会影响到码头安全。
