Which types of gears are used in constant mesh gearbox?(a) Spur gear(b) Helical gear(c) Bevel gear(d) Worm gearI had been asked this question in an online quiz.My question is taken from Transmission System topic in section Chassis & Transmission System of Automobile Engineering

Answer» CORRECT choice is (b) HELICAL gear

To explain: As the gears are ALWAYS in mesh in the constant-mesh gearbox, therefore there is no need for using the spur gears and the helical gears are used as those are QUITE in use.
