The point on a pulley where it pivots is called the axle or the shaft. It serves as the point of rotation for the pulley system.

The part of a pulley where the rope lies is called the groove or the sheave. This is the part of the pulley that provides the surface for the rope to run along while the pulley rotates.

That would be the crankshaft pulley.
That is the idler pulley. The other pully to the bottom left of that one is the tensioner pulley.
The driver pulley is the pulley connected to the power source (like a motor), while the driven pulley is connected to the driven load (like a conveyor belt). The driver pulley transfers rotational force to the driven pulley through a belt or chain, allowing the load to be moved or operated.
The part of the rope from the pulley to the effort is called the "effort line" or "effort segment." This segment is where the force is applied in a pulley system to lift or move a load. In mechanical terms, it plays a crucial role in determining the mechanical advantage of the pulley system.
This mainly occurs in a multiple pulley system, but there is no particular name for it.
