The invention relates to the technical field of helicopters, and in particular relates to a tail rotor transmission structure of a helicopter. The tail rotor transmission structure comprises a main rotor assembly which is rotatably arranged on the helicopter body of the helicopter, and the main rotor assembly is vertically arranged and can drive a main rotor to rotate on a horizontal plane; the tail rotor transmission structure further comprises an adapter shaft assembly which is rotationally arranged on the helicopter body, and the adapter shaft assembly is horizontally arranged; the tail rotor transmission structure further comprises a first transmission belt, one end of the first transmission belt is in transmission connection with the main rotor assembly, and the other end of the first transmission belt is in transmission connection with the adapter shaft assembly; the tail rotor transmission structure further comprises a tail rotor assembly which is arranged on the helicopter body and is in transmission connection with the adapter shaft assembly, and the tail rotor assembly can drive the tail rotor to rotate on a vertical plane under the transmission of the adapter shaft assembly. The manufacturing difficulty of the tail rotor transmission structure can be reduced, the cost is reduced, vibration generated by the tail rotor is prevented from being transmitted to the helicopter body, and the reliability is improved.

    本发明涉及直升机技术领域,尤其涉及一种直升机的尾旋翼传动结构,其包括主旋翼组件,转动设置在直升机的机身上,所述主旋翼组件竖直设置,能够带动主旋翼在水平面上转动;转接轴组件,转动设置在所述机身上,且所述转接轴组件水平设置;第一传动带,一端与所述主旋翼组件传动连接,另一端与所述转接轴组件传动连接;尾旋翼组件,设置在所述机身上,且与所述转接轴组件传动连接,所述尾旋翼组件能够在所述转接轴组件的传动下带动尾旋翼在竖直面上转动。本发明能够降低尾旋翼传动结构的制造难度,降低成本,而且避免尾旋翼产生的震动会传到机身,提升可靠度。
