This gearbox has a large gear ratio (500), despite its compact size. The first stage is made in the form of a planetary gearbox, and the second in the form of a wave transmission. The device has a fairly good kinematic error, a large output torque, which will allow you to accurately position the position of the mechanism attached to it. This gearbox has a fairly extensive application: in machine tool construction, automotive, shipbuilding, robotics and space industry. It can easily scale for more serious tasks. A small number of parts increases the reliability of the device, those parts of which it consists can be produced at almost every factory. Also, the input and output links are hermetically separated from each other. At this stage, the gearbox only exists as a 3D model and drawings.
