reduction drive
nounMaschinenbau
A device which reduces the input rotational speed to a lower output speed, and can also increase torque.
Warum dieses Wort
The trade is the whole point: speed goes down, torque goes up, minus friction losses. Motors are cheap and efficient at high rpm, but almost nothing a machine actually does wants those rpm at the shaft.
In use
Motor's fine, it's the reduction drive that's howling, so pull the cover and check the oil before we order anything.
