Miniature bevel gears - Ringgearpinions

Miniature bevel gears serve to slow down a rotation and allow smooth transitions between rotations. They’re unique in that they turn both clockwise and counter-clockwise (sometimes both at the same time). Their small bevel gears create a powerful frictional force, making them ideal for slowing the motion of a flywheel.

Bevel gears are usually used as an alternative to the sliding gear: the reason is that they are simpler for the application of a torque load and are less likely to lose teeth, and because of their small size they can produce a high torque with a small amount of power, which reduces both noise and backlash. This miniature bevel gears — also known as a spur gear — is available in a variety of versions, including full-face bevel gears, partial-face bevel gears, and internal spur gears.
