The S1B83A-C048B090D is a 90 teeth anti-backlash worm gear with a 20° pressure angle and a face width of 0.1875 inches. It is designed for use with matching worms that have a double thread configuration. The gear is constructed from bronze (QQ-B-637 Alloy 464) for the gear body and 303 stainless steel for the hubs, ensuring durability and resistance to wear. The bore size is available in .1873 inches, and it is compatible with various screw sizes, including #4-40. This worm gear is suitable for applications requiring low noise and vibration due to its gradual tooth engagement. Special orders can be placed for different tooth counts or bore sizes.
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.
