The invention provides a transmission device, and relates to the technical field of piston type internal combustion engines and helicopters. The transmission device is used for an in-line piston engine and comprises a crank-link mechanism and a speed reducing mechanism, the crank-link mechanism is in driving connection with the speed reducing mechanism, a propeller shaft used for providing power for rotation of a propeller is arranged at the tail end of the speed reducing mechanism, and the reducing mechanism is in driving connection with the propeller shaft. According to the transmission device, the defects of high cost and large dead weight caused by the fact that an oil-electricity hybrid power transmission device of a traditional unmanned aerial vehicle needs to be provided with a power supply (battery) for starting an engine and a high-capacity battery for driving the motor besides the engine and the high-power electric motor are overcome. The defects of large number of parts and heavy dead weight caused by the fact that main parts of a piston type engine, such as a cylinder body, a cylinder head, a cylinder cover, an air valve and a valve, need to be symmetrically arranged left and right in a horizontally opposed piston engine of a traditional unmanned aerial vehicle are further overcome.

    本发明提供了一种传动装置,涉及活塞式内燃发动机和直升机技术领域,该传动装置用于直列式活塞发动机,包括曲柄连杆机构和减速机构,曲柄连杆机构与减速机构驱动连接,减速机构的末端设有用于为螺旋桨旋转提供动力的螺旋桨轴,减速机构与螺旋桨轴驱动连接。本发明克服了传统无人机的油电混合型动力传动装置除了需要配置发动机和高功率电动马达以外,还要配置发动机启动用的电源(电池)和驱动马达的大容量电池,从而导致成本高和自重大的缺陷。本发明也克服了传统无人机的水平对置活塞发动机因为需要将活塞式发动机的主要零部件包括缸体、缸头、缸盖、气门和阀门等左右对称布置,从而导致零部件数量多和自重大的缺陷。
