Gears might be “old” technology, but they are still considered the most rugged type of mechanical drives. They transmit power with efficiencies of up to 98% and have long operational lives. That’s why ...

Helical gears are cylindrical disks which have involute-shaped teeth cut into their face at a helix angle. By slanting the teeth, helical gears can obtain a large contact ratio and the gradual change ...

Even before the Industrial Revolution, gears of one kind or another have been put to work both for and against us. From ancient water wheels and windmills that ground grain and pounded flax, to the ...

The choice between helical and spur gears in gearboxes may seem straightforward. Go with helical gears if you want the gearbox to run as smoothly and quietly as possible. Choose spur gears when you ...

Gears are toothed wheels that transmit motion from one shaft to another and determine the speed, torque, and direction of rotation of machine elements. Gears can be grouped into two major categories: ...

Model 200 hobbing machines from Koepfer America LLC feature eight axes with gantry loading systems for most gear-cutting applications including timing one gear to another on the same workpieces and ...
