KHK USA Inc., distributor of the KHK® brand of metric gears, announces its extensive line of metric worm gears, manufactured to the highest quality standards by Kohara Gear Industry Co., of Japan. KHK’s large selection of worm gears are very quiet and provide smooth transmission of power and are suitable for a very wide range of applications where a large speed reduction is required in a compact space.

KHK worm gear pairs are offered in many modules, numbers of teeth and reduction ratios. Available materials for worms include structural carbon steel (S45C, etc.), structural alloy steel (SCM415, etc.), stainless steel, and cast iron. Worm wheels are available in cast iron (FC200, etc.), nonferrous metals such as phosphor bronze and specialty bronze (nickel bronze, aluminum bronze, etc.), and engineering plastics such as MC Nylon.

All KHK worm wheels and most of the worms allow for secondary operations such as opening the bore, adding of keyways, adding of tapped holes, and the reduction of the hub diameter or shaft diameter to be performed. KHK USA stocks products which have already had some of these secondary operations completed.

Worm gears are one type of gears that transmit motion between non-intersecting and non-parallel shafts. Their shaft angles are generally 90 degrees. There are roughly two types of worm gears. One is a worm in cylindrical form meshing with a worm wheel, the pair comprising a “cylindrical worm gear,” and the other an hourglass form worm and its mating worm gear called “hourglass worm gear.”
