In helical gears, the right hand helices on one gear will mesh ____________ helices on the other gear.

In helical gears, the right hand helices on one gear will mesh ____________ helices on the other gear. Correct Answer left hand

A helical gear has teeth in form of helix around the gear. Two such gears may be used to connect two parallel shafts in place of spur gears. The helixes may be right handed on one gear and left handed on the other.
