Name of the Part: Pulley

The pulley is a wheel with a groove in it where the belt rests. The belt is like a small
rubber band, which connects to a part of the model that is rotating, transferring
the rotation to a different part of the model.
Pulley up: a large pulley drives a small pulley to produce more rotations.
Pulley down: a small pulley drives a large pulley to produce less rotations.
Pulley twist: it is used to make shafts that are parallel but rotate in opposite
directions.
For example, used in these Design Library base models:
Reel, Lift, Drive, Sweep, Revolve, Grab
Important
Using a pulley in a mechanism will prevent the model from breaking when it meets
resistance as the belt will slip in the pulley.
