Hi, Gear systems can be used to lower RPM, thus increasing torque, correct? If so, can they be used the other way round? For example if I had a high toque motor, I could lower the torque and increase the RPMs?
Yes.
This is normal in clock work, however the tooth form is always close to epicycloidal which I understand is not ideal for power transmission in which the speed is reduced and torque increased.

IIRC the cycloidal form has less friction than the involute form at the expense of vibration.
