KHK USA, Inc.
Metric Worm Gears Large Speed Reduction With Small Volume. Worm gear pairs are made up of a worm and a worm wheel. These gears allow for a very large reduction ratio in a single pair. They are very quiet and provide smooth transmission of power. Due to the situation of being a friction drive mechanism, worm gear pairs have very poor efficiency. Similar to helical gears, worm wheels are also cylindrical disks which have involute shaped teeth cut into their face at an angle. For worm gear pairs, this is the lead...
