The KCG2-60L1J12 is a left-hand lead cast iron worm wheel with a 60:1 reduction ratio, module 2, 60 teeth, 1 start, and a 12 mm bore. It has a face width of 22 mm, a pitch diameter of 120.25 mm, and an outside diameter of 126 mm. The worm wheel is precision grade KHK W 002 grade 4, with a normal pressure angle of 14° 30′, and features a standard full-depth tooth profile. Allowable torque at 30 rpm is 56.4 N·m, decreasing to 27.2 N·m at 1200 rpm, with a backlash of 0.10-0.28 mm and a weight of 1.44 kg. The product is designed for use with steel worms, and is profile-shifted to achieve precise center distance. The J-series variant is available on request with a lead time of five working days and requires a minimum order of 1-20 units.
Module 2, 60 Tooth, 1 Start, Left Handed Cast Iron Worm Gear with 12mm 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.
