Which manufacturing process finishes a crown wheel and pinion?

  • A.Lapping the pair together after heat treatment
  • B.Grinding each gear separately, which produces a more accurate surface than lapping the two together is able to give
  • C.Shot peening
  • D.Honing with an abrasive stone, which removes the distortion produced during the hardening of the two components

Answer: A

The pair is run together with an abrasive compound after hardening, which corrects the heat treatment distortion and gives the matched contact pattern. That is why they must be replaced together. Ground sets are used where the highest accuracy is needed. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. The shared behaviour explains why these belong together and the differences explain why both exist.
