The KPG2-20R1J16 is a right-hand lead plastic worm gear with a module of 2, 20 teeth, one start, and a 16 mm bore, designed for use with stainless steel worms. It features a standard full-depth tooth profile with a normal pressure angle of 20°, constructed from MC901 nylon. The gear has a pitch diameter of 40.34 mm, an outside diameter of 44 mm, a face width of 22 mm, and a hub width of 13 mm. The allowable bending torque is 8.54 N·m (0.87 kgf·m), with a backlash range of 0 to 0.33 mm and a weight of 0.046 kg. The product is profile-shifted to maintain proper center distance and requires lubrication when operated above the bracketed torque limit. Dimensional stability may vary with temperature and humidity.
Module 2, 20 Tooth, 1 Start, Right Handed Nylon Worm Gear with Finished 16mm 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.
