The invention discloses a rotor head and a helicopter, and relates to the technical field of aircrafts. The rotor head comprises a propeller hub, a connecting mechanism, a propeller clamp and an adjusting transmission mechanism, a rotor main shaft of the helicopter is sleeved with the propeller hub, the connecting mechanism is connected to the propeller hub and comprises a transverse shaft, the transverse shaft is rotatably sleeved with the propeller clamp, the propeller clamp is used for being connected with a propeller blade, and the adjusting transmission mechanism is in transmission connection with the propeller clamp. The adjusting transmission mechanism is used for driving the paddle clamp to rotate relative to the transverse shaft, one of the paddle clamp and the connecting mechanism is provided with a limiting groove, the other one of the paddle clamp and the connecting mechanism is provided with a limiting protrusion, and the limiting protrusion is inserted into the limiting groove so as to limit the rotating stroke interval of the paddle clamp relative to the transverse shaft. By means of the arrangement, even if control over rotation of the propeller clamp is lost due to damage of the adjusting transmission mechanism, the propeller clamp does not rotate at will at a large angle and is kept within a certain rotation stroke interval, and therefore the safety of the helicopter can be improved.
本申请公开了一种旋翼头和直升机,涉及飞行器技术领域。本申请提供的旋翼头包括桨毂、连接机构、桨夹以及调节传动机构,桨毂用于套设于直升机的旋翼主轴,连接机构连接于桨毂,连接机构包括横轴,桨夹可转动地套设于横轴,桨夹用于连接桨叶,调节传动机构传动连接于桨夹,调节传动机构用于带动桨夹相对于横轴转动,桨夹与连接机构中的一者设置有限位槽,桨夹与连接机构中的另一者设置有限位凸起,限位凸起插入至限位槽中,以限定桨夹相对于横轴的转动行程区间。如此设置使得即便因调节传动机构损坏而失去对桨夹转动的控制,桨夹也不会大角度任意转动,而是保持在一定转动行程区间之内,因此可以提高直升机的安全性。
