Ground helical gear with module 3, 32 teeth, left-hand helix, and plain bore, designed for use with matching right-hand gears. Power transmission rated for allowable torque of 407 N·m (bending) and 41.5 N·m (surface durability). Tooth hardness ranges from 50 to 60 HRC, with material SCM440 and induction-hardened surfaces. Helix angle is 21°30', transverse pressure angle is 20°, and precision grade conforms to JIS B1702-1:1998 Grade N6. Face width is 25 mm, hub width is 16 mm, and total length is 41 mm. Backlash is specified as 0.12~0.22 mm. Weight is 1.82 kg. 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.
