China best Internal Spur Gear with Great quality


Internal Spur Gears, unlike spur gears, have the teeth generated on the inner diameter, Of the blank. They are generally more robust and more efficient than the mating pinion gear. The pitch diameter of the internal Gear must be at least 1.5 times the P.D. of the mating pinion. If this condition is not met, interferences between the tips of the teeth will occur.

Internal gears allow designers to achieve higher contact and drive ratios than standard spur gears at shorter center distances. They also enable a velocity change without a directional change, which would require an idler gear with classic spurs.
