Each gear of the pair is an ordinary helical gear, of the type described in chapter 13. B) books are available providing the necessary guidance. 2 — what kind of gears should i use? Crossed helical gears provide flexibility in design, but the contact between teeth is closer to point contact than line contact, so they have lower force capabilities than parallel shaft designs.
