The invention relates to the technical field of paddle equipment, in particular to a contra-rotating paddle operation device and an engine, and the contra-rotating paddle operation device comprises a first rotating shaft, a second rotating shaft, a first power mechanism, a second power mechanism, a first transmission mechanism and a second transmission mechanism, first blades are arranged at one end of the first rotating shaft; second blades are arranged at one end of the second rotating shaft; the output end of the first power mechanism and the output end of the second power mechanism are arranged in the radial direction of the first rotating shaft and the second rotating shaft. The first power mechanism and the second power mechanism are connected with the first rotating shaft and the second rotating shaft through the first transmission mechanism and the second transmission mechanism; a first bias assembly is arranged in the first transmission mechanism, and the input end and the output end of the first transmission mechanism are arranged in a staggered mode through the first bias assembly. The overall length of the shafting can be kept unchanged, meanwhile, the occupied space of the first power mechanism and the second power mechanism is increased, the situation that the output power is affected due to size limitation is avoided, and the power transmission effect is guaranteed.

    本发明涉及桨叶设备技术领域,具体提出一种对转桨叶运行装置和发动机,其中,对转桨叶运行装置,包括:同心的第一转轴和第二转轴、第一动力机构和第二动力机构、第一传动机构和第二传动机构;第一转轴一端设有第一桨叶,第二转轴一端设有第二桨叶;第一动力机构的输出端和第二动力机构的输出端沿第一转轴和第二转轴的径向设置;第一动力机构和第二动力机构通过第一传动机构和第二传动机构与第一转轴和第二转轴连接;第一传动机构内设有第一偏置组件,第一传动机构的输入端和输出端通过第一偏置组件错位设置。能在维持轴系整体长度不变的同时,提高第一动力机构和第二动力机构的可占用空间,避免因受尺寸限制影响输出功率,保证动力的传动效果。
