Transmission gear shafting arrangement

The invention relates to an arrangement structure of a gearbox gear shaft system. The structure comprises an input shaft, and two output shafts which are parallel to the input shaft and are positioned on the two sides of the input shaft, wherein the input shaft is fixedly provided with driving gears; the output shafts are sleeved with driven gears; the gears of the output shafts are provided withconnecting devices; the driven gears are meshed with the driving gears; a second driven gear and a third driven gear are simultaneously meshed with a second and third driving gear; and a reverse gearconnecting device is arranged on one output shaft. Through the structure, an inner space of a gearbox can be reasonably utilized, the gear ratio is well matched because a duplex gear is arranged, andthe structure is uniformly stressed and has a compact layout.
