Morphology

idle + wheel

The meaning — a wheel that is not actively transmitting power — is directly derivable from the constituents 'idle' (not active) + 'wheel' (rotating device), so a B1 learner who knows both words can infer the general idea. The precise technical function (guiding or tensioning a belt) is specialized vocabulary, but this does not prevent the core sense from being transparent.

Etymology

Idle wheel is a name for a wheel that is idle — it turns but does not give power, and it simply presses on a belt to 'guide' or 'tighten' it. That's why the term means a wheel used to help the belt work without driving the machine.
