The KCG2.5-50R1J15 is a right-hand lead bronze worm wheel in the KCG Series with a 2.5 mm module, 50 teeth, 1 start, and a 15 mm bore. It has a 125.29 mm pitch diameter, 130 mm outside diameter, and 22 mm face width. The worm wheel is designed for use with a KSW2.5-R1J15 worm, which has a 15 mm hub length, 30 mm total length, and a 5 mm × 2.3 mm keyway. The assembly operates with a backlash of 0.13-0.31 mm and weighs 1.46 kg. The precision grade is KHK W 002 grade 4, with a 20° normal pressure angle and standard full-depth teeth. The material is CAC502, with no heat treatment applied.
Module 2.5, 50 Tooth, 1 Start, Right Handed Cast Iron Worm Gear with 15mm 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.
