Module 1 right-hand ground helical gear with 45 teeth, plain bore, and 8 mm face width. Made of SCM440 with tooth surface induction hardened to 50-60 HRC, featuring a 21°30' helix angle and 20° transverse pressure angle. Precision grade conforms to JIS B1702-1:1998 Grade N6. Axial thrust is produced during operation. Allowable torque is 26.5 N·m (2.71 kgf·m) for surface durability and 20.7 N·m (2.12 kgf·m) for bending strength, with backlash ranging from 0.08 to 0.16 mm. Weight is 0.140 kg. No secondary operations are permitted on gear teeth 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.
