The KKHG2-30LJ28 is a left-handed ground helical gear with a module of 2 and 30 teeth. It features a finished bore of 28mm, making it suitable for various applications requiring precise gear engagement. The gear is manufactured from SCM440 material and undergoes thermal refinement with induction hardening, resulting in a tooth hardness of 50 to 60 HRC. The design includes a transverse pressure angle of 20¬8 and a helix angle of 21¬830', ensuring efficient power transmission. The allowable torque for this gear is calculated based on specific usage conditions, and it produces axial thrust forces during operation. The gear is precision graded to JIS grade N6, adhering to industry standards for quality and performance.

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.
