Module 1 right-hand ground helical gear with 24 teeth, plain bore, and 8 mm face width, manufactured from SCM440 steel with induction-hardened tooth surfaces at 50-60 HRC. It meets JIS grade N6 (JIS B1702-1:1998) and JIS grade 2 (JIS B1702:1976) precision standards, has a 21°30′ helix angle, 20° transverse pressure angle, and standard full-depth teeth. The gear has a bore diameter of 20 mm, pitch diameter of 24 mm, outside diameter of 26 mm, hub diameter of 30 mm, hub width of 10 mm, and total length of 18 mm. It has an allowable torque of 10.1 N·m (bending strength) and 7.43 N·m (surface durability), with backlash of 0.08-0.16 mm and weight of 0.046 kg. Axial thrust forces are generated; secondary operations on tooth areas 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.
