Miter gear series

July 18, 2022

KHK USA Inc.’s miter gears are available in high precision grades to perform at demanding torques and speeds, and they are also available in commercial grades for economical applications. Miter gears are bevel gears with two rotational axes that intersect at 90° and with a 1:1 gear ratio. They are shaped as a right circular cone and their set of gear teeth intersects at the pitch apex of each gear. The miter gear tooth profile is octoidal, in contrast to that of a cylindrical gear tooth profile which is an involute tooth form. A variety of miter gear styles — from spiral and straight tooth to Zerol miter gears, and more — are offered by KHK to fit a wide range of high precision and commercial applications. These models span various materials, configurations, modules, and numbers of teeth. Many of the miter gears also enable secondary operations such as opening the bore, adding keyways, adding tapped holes, or reducing hub diameter. KHK ground spiral miter gears are available in two models. One is high strength, abrasion-resistant, and compact for high speed and torque applications. The other is affordable and re-machinable. The spiral miter gears are also available in three additional models, each with varying levels of secondary operations performed and varying numbers of teeth.
