KCG2-50R1 is a right-hand lead, 50:1 reduction, cast iron worm wheel with a 12 mm bore, 48 mm hub diameter, 100.21 mm pitch diameter, 104 mm throat diameter, 106 mm outside diameter, and 22 mm face width, designed for use with a module 2 steel worm gear. It has a standard full-depth gear tooth with a 14°30' pressure angle, a normal plane reference, and a permissible backlash of 0.10 to 0.28 mm. The allowable torque at 50 rpm is 40.3 N·m, decreasing to 19.1 N·m at 1200 rpm. Weight is 1.01 kg, and mounting distance is 65.5 mm.
Module 2, 50 Tooth, 1 Start, Right Handed Cast Iron Worm Gear with Plain 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.
