Abstract
The utility model relates to a gearbox, belongs to the technical field of machines, and discloses a combined speed change gearbox. The combined speed change gearbox comprises a shell body. A power input shaft, speed change shafts and power output shafts are arranged on the shell body. The power input shaft, the speed change shafts and the power output shafts are provided with gears which are meshed with each other. The power output shafts are provided with first power output devices. The speed change shafts are provided with second power output devices. A gear-shifting device installation hole in each second power output device is formed in the shell body. A plurality of gears outputting power are arranged on the speed change shafts, and one of the gears transmits the power onto the power output shafts. The second power output devices are transmission parts with at least one of the other gears transmitting the power outwards through output ports. The portions, between the power output shafts, of the speed change shafts are connected through a plurality of sets of sliding gears, and the sliding gears are controlled by shifting forks connected with blocking rods. Therefore, the combined speed change gearbox has the advantages that the structure is compact and one box body can output a plurality of transmission powers.
