Morphology
The noun is a literal compound: combining 'spur' (a spike-like projection) with 'wheel' yields a wheel bearing projecting teeth or spurs, which matches the provided definition. Although technical, the meaning is compositionally predictable and follows transparent naming patterns found in many languages, so a learner who knows both constituents should be able to infer the sense.
Etymology
Spur wheel comes from the simple image of a spur and a wheel: little pointed teeth that stick out like the points on a spur and push against another gear. Those teeth fit side by side with a matching gear, so spur wheel means 'a gear wheel with teeth that meet another gear in the same flat plane'.
