Mutually perpendicular i. Bevel ii. Worm b. Parallel i. Spur ii. Herringbone 2) An idler inserted between the driving and driven gears affects the direction of rotation while having no effect on the forces between the gears. 3) Helical gears run greater than spur gears as they produce less vibration which allows for greater efficiency and longer lifespan. 4) The difference between a herringbone and double helical gear is that herringbone gears do not have a groove, so each tooth meets in the middle, whereas double helical gears do have this groove in order to separate teeth.
