KHK USA Inc.

KHK USA Inc. (Mineola, NY) announced its extensive line of metric worm gears, manufactured by Kohara Gear Industry Co., of Japan.

The company’s large selection of worm gears are very quiet, 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.

Unique to KHK is the Duplex Worm and Worm Wheel pair. The Duplex Worm pair incorporates a worm with a variable pitch and a mating wheel. The variable pitch of the worm allows for it to be positioned in such a fashion that all backlash between the pair is eliminated when the worm is moved axially.

Features:

  • Offered in many modules, numbers of teeth and reduction ratios
  • Available materials for worms include carbon steel (S45C), Chromalloy steel (SCM415), and stainless steel (SUS303)
  • Worm wheels available in cast iron (FC200), nonferrous metals such as phosphor bronze and aluminum bronze and engineering plastics such as MC901 nylon.
  • All KHK worm wheels and most worms allow for secondary operations such as opening of bore, adding of keyways, adding of tapped holes and reduction of hub diameter or modification of shaft diameter to be performed
