Gears have been used since around 350 B.C. (2,300 years ago). Gears still retain their original form to this day. One of the reasons may be that they are rather simple in construction. Many technicians today still make an effort to improve and perfect the science of gears.
"KHK Gear World" is the site to provide the gear learners with information on gears. In addition to the introductory course for beginners it contains some reference materials for advanced learners. It also contains "virtual factory tour", and you can see and learn, by watching images, how gears are made by KHK. We would be happy if you would find them useful and intriguing.
The use of gears as a machine element There are various types of gears. And by using varying combination of gears and shafts, you can make out various movements, such as increasing torque, adjusting speed, and changing the direction of motion, etc.
Introduced here with video images, graphics and sound are gear trains and the examples how gears are used.
Virtual factory tour If you are not familiar with how gears are made, please visit our "virtual factory tour." You can see and learn through video images how gears are made by KHK.
Introduced here are the gear-tooth cutting process for each type of gear, the process of keyway broaching., etc.
