Bevel Gear Types - KHK

The Japanese manufacturer KHK offers a variety of high-quality bevel gears that are readily available. Bevel gears, are typically provided as a pair of gears and are designed to transmit torque between two intersecting and perpendicular shafts.

Bevel gears can be categorized into the following 3 groups:

1. Straight bevel gears
2. Spiral bevel gears
3. Hypoid gears

Bevel gears are widely used in industries such as robotics, pharma, automotive, and military, especially when there is a need to efficiently transfer forces between perpendicular shafts.

KHK's bevel gears are manufactured using a wide range of materials, including plastic, non-ferrous metals, copper, aluminum, steel, iron, stainless steel, and more.

Bevel Gears Types:

Straight Bevel Gears:

Straight bevel gears are the most common and simplest type of bevel gears. The teeth of straight bevel gears are straight and easier to manufacture. The gear ratio, torque reduction, or speed increase can be adjusted according to the gear ratio.
