The gears that have non-intersecting shafts are hypoid gears, crossed
helical gears and worm gears. These gears provide an effective answer
for power transmission applications requiring high-ratio speed reduction
in a limited space using non-intersecting shafts. These are ideal for
applications requiring only limited load capacity. Lowering ratios
easily increases their efficiency. These gears are the cheapest of all
gears; the cost of manufacturing is cheapest of all other gears. They
are widely used in automobile differentials, electric mixer,
speedometer, sprinkler, machine tools, and packaging machinery.
