The invention relates to a helicopter crossed forward and reverse rotor wing parallel driving device. The device comprises a support assembly, rotor wing assemblies and a transmission assembly; the rotor wing assemblies are symmetrically connected to the left side and the right side of the upper portion of the support assembly through revolute pairs and incline outwards by a certain angle; the transmission assembly is arranged in the middle of the interior of the support assembly; the two sides of the transmission assembly are connected with the corresponding rotor wing assemblies; a driver isfixed to the bottom of the support assembly and is in coaxial key connection with the bottom of the transmission assembly; the outer side of the middle of the support assembly is connected with a base through a ball sleeve; the middle of the base is connected with the ball sleeve through a ball pair; the ball sleeve is connected with the outer side of the middle of the support assembly through acylinder pair; and linear driving rod assemblies are circumferentially and evenly distributed between the base and the bottom of the support assembly. According to the device, gears are driven by thedriver to drive the rotor wing assemblies to rotate forwards and backwards in a meshed transmission mode, empennage transmission can be avoided, and cross rotation interference of the rotor wing assemblies is prevented; the linear driving rods drive the support assembly to swing in a three-dimensional mode, the synchronous swing of the rotor wing assemblies is guaranteed, and flight directions canbe flexibly changed.
