The invention discloses a helicopter torque transmitting mechanism and a helicopter speed reducer transmission device. The helicopter torque transmitting mechanism is of a cylindrical structure and is embedded between an inner spline shaft of a speed reducer and an outer spline shaft of a transmission accessory. An outer spline tooth face connected with the inner spline shaft is arranged on the outer wall of the helicopter torque transmitting mechanism. An inner spline tooth face connected with the outer spline shaft is arranged on the inner wall of the helicopter torque transmitting mechanism. The hardness of the helicopter torque transmitting mechanism is smaller than the hardness of the inner spline shaft and the hardness of the outer spline shaft. The outer spline shaft and the inner spline shaft are not prone to abrasion, abrasion happens on the helicopter torque transmitting mechanism, the helicopter torque transmitting mechanism is arranged in an embedded manner and is easy to replace, a client can car
