How Does a Planetary Gearbox Work? Planetary Gearboxes are a type of gearbox where the input and output both have the same centre of rotation.
Hub motors have to be able to produce any combination of speed and torque without a gearbox; they usually work by "direct drive." But there's a snag: in electric bikes, they sit inside the hub, at the very center of a relatively large, spoked wheel. If you turn the center of a ...
The reason for these restrictions is that the internal fluidpumpof the gearbox, being driven by the engine, does not work when the engine is not running. When the car is being towed, therefore, the box is not lubricated or cooled.
As the video makes clear, the big deal here is making an IVT - actually, a mere CVT, that still needed a clutch, would do - that uses standard gearbox-y sorts of components, or can in some other way handle lots of power and torque without being unmanageably big, expensive and/or q...
work with mechanisms all day to intuitively grasp, but there aren't many components in there, and none of them are under 100 years old. Actually, that's probably a considerable understatement; I'm not sure whenepicyclic gearingbecame common knowledge among cunning artificers, but I can't ...
