Gearbox and Transmission System

A transmission system, comprising a motor and a gearbox, the gearbox comprising:

• a box, provided with a hollow chamber;
• a worm shaft;
• a first gear, connected with a first rotating shaft, comprising a first gear segment and a second gear segment, rotated around an axial direction of the first rotating shaft;
• a second gear, connected with a second rotating shaft, rotated around an axial direction of the second rotating shaft;
• and
• an output shaft, in transmission connection with the second gear,
• wherein the worm shaft, the first gear, and the second gear are all provided in the chamber, the output shaft extends out of the chamber, the worm shaft is engaged perpendicular to the first gear segment so that the axial direction of the first rotating shaft is perpendicular to an axial direction of rotation of the worm shaft, the second gear segment is engaged perpendicular to the second gear so that the axial direction of the second rotating shaft is perpendicular to the axial direction of the first rotating shaft, and both ends of the first rotating shaft and both ends of the second rotating shaft are all mounted in the box;
• a motor output shaft is coaxially in transmission connection with the worm shaft, and the output shaft of the gearbox is coaxially in transmission connection with the motor output shaft and the worm shaft.
