The KCG2 series comprises gray iron worm wheels with a module of 2, 40 teeth, and a normal pressure angle of 14°30'. The KCG2-40R1 variant is a right-hand lead wheel with a 12mm bore, 45mm hub diameter, 80.17mm pitch diameter, 84mm throat diameter, 86mm outside diameter, and 22mm face width. It has a hub width of 13mm, overall length of 55.5mm, and weighs 0.96kg. The wheel has a maximum allowable torque of 26.7N·m at 30rpm and 12.3N·m at 1200rpm, with backlash between 0.10mm and 0.28mm. Precision grade is KHK W 002 grade 4. The J series with modified bores is available on request but not documented for KCG2-40R1J16 in the provided data.
Module 2, 40 Tooth, 1 Start, Right Handed Cast Iron Worm Gear with 16mm Finished Bore
A worm gear pair, or worm gear set, consists of two gears: the worm, which resembles a spiral screw, and the worm gear (aka, worm wheel).
For the pair to mesh, the worm and worm gear must have the same pressure angles, modules, and lead directions (left- or right-hand).
A worm revolves on a shaft that’s perpendicular to the worm gear and the shaft angle is typically 90°. Because the teeth gradually mesh as the worm rotates, there is low noise and low vibration.
