HST-III harmonic gearbox manufacturer tells you that a gearbox is a mechanical device used to increase/decrease torque by decelerating/increasing. The HST-III harmonic gearbox manufacturer tells you that it consists of two or more gears, one of which is driven by an electric motor.

The HST-III harmonic gearbox manufacturer tells you that the output speed of the gearbox is inversely proportional to the gear ratio. Gearboxes are often preferred in constant speed applications, such as conveyors and cranes, which can provide increased torque.
HST-III harmonic gearbox manufacturer tells you that the gearbox consists of a drive gear with a certain diameter, another gear with a smaller gear connected to the drive mechanism (electric motor, wind turbine, diesel engine, etc.) (if the driven mechanism's The drive speed is higher than the drive mechanism) diameter (if the speed of the driven mechanism should be less than the speed of the drive mechanism) is connected to the mechanical load being driven. Just the speed/torque increase/decrease or vice versa mechanism. This is a mechanical motor attachment.
The above information is the HST-III harmonic gearbox manufacturer's introduction and analysis of the structure of the gearbox, hope it helps you.
