Module 1 ground helical gear with 40 teeth, right-hand helix, and a 30 mm bore, made of SCM440 steel with induction-hardened teeth at 50-60 HRC, conforming to JIS grade N6 (JIS B1702-1:1998) and JIS grade 2 (JIS B1702:1976). The gear has a 21°30' helix angle, 20° transverse pressure angle, and standard full-depth teeth. It is designed for axial thrust load applications, with a total length of 18 mm and an allowable torque of 17.9 N·m (bending strength) and 20.5 N·m (surface durability). Backlash is specified as 0.08-0.16 mm. Secondary operations on the tooth area are prohibited due to induction hardening.

Helical gears are comparable to spur gears, but due to the higher contact ratio, they are quieter, vibrate less, and experience less friction. Helical gear pairs have the same helix angle but opposite threads (left-hand and right-hand). Helical gears can be used in place of spur gears; they can be used in drives with non-parallel axes or positioned in between parallel axes. Helical gears are suitable for applications involving faster speeds and larger loads because, unlike spur gears, their teeth are twisted along the helical path and progressively interlock into one another.
Helical gears can also be found in industries related to movable earth, power, and oil drilling. Because of their efficacy with heavy loads, they are found in elevators, conveyors, compressors, and blowers. The most popular helical gear application is in the automobile industry, specifically in transmissions.
Our inch and metric helical gears are offered in 48-pitch modules 1, 2, and 3.
They are available in stainless steel, aluminum, and ground-hardened steel with black oxide finishes.
