I was fascinated by this type of gearbox and always wanted to make one. This type of gearbox is one of the most used in industrial robots. This type of gearbox only has a single reduction (in this case 2 because of the belt reduction) with a very high reduction ratio. Because of the single stage reduction there's almost no tolerance/play between input and output shaft. Conventional gearboxes use more gears to achieve the same reduction ratio, the tolerances between the gears add up resulting in greater tolerances/play between the input and output shaft.

This type of gearbox is mostly used in servo systems used in industrial robotics and space applications.

Here are some specifications of the gearbox:
Max tested torque at 12V: 41.3kg*cm or 4N*m
Total reduction ratio = 54:1

Disclaimer: I do not own the Dodge Charger shown in the video, i was just fortunate enough to borrow it for a limited time 😅. (I really wished I owned one though).
