Gear Motions, Inc.
Custom Worm Gears Worm Gears. A worm gear system consists of a worm and worm wheel positioned as a cross axis and is the most compact type of gear system. Due to the compact design, worm gear reducers are able to be placed in relatively small spaces and provide high-ratio speed reduction. Worm gears are known to run smoothly and quietly, as long as they are properly mounted and lubricated. Due to these features, typical worm gear applications include presses, small engines, lifts and elevators, rolling mills... (read more)Browse Worms and Worm Gears Datasheets for Gear Motions, Inc. -
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...
