  1. In normal helical gears there is no problem of impact stresses but there are axial thrusts on the bearings of shafts on which they are mounted.these gears are good for moderate power transmission because bearing can be designed.But in very high power transmission design of bearing for a small and compact system becomes very tough and unemployable.Thus herringbone gears were designed to eliminate these axial thrusts.This gear contains both right hand helical profile and left hand helical profile on same gear as you can see in diag. .The axial components of transmission force is cancelled by each other on same gear.Thus eliminating the problem of thrust force. these gears are used in racing cars where high power transmission is required and bearing size can not be increased after certain limit.
