In rope rescue, what term is used for the wheel that the rope rides over in a pulley system?

Explanation:
In rope rescue, the wheel that the rope rides over in a pulley system is called a sheave. The rope sits in the groove of the sheave, which lets it change direction and carry load with minimal friction. The whole device is a pulley, but the specific wheel inside is the sheave. A piston is a hydraulic component and not part of a pulley system. A sprocket is a toothed wheel used with chains, not rope, and the term pulley wheel isn’t the standard name in this context.
