Module 1 right-hand ground helical gear with 70 teeth, tooth hardness of 50-60 HRC, made from SCM440 with induction-hardened surface, helix angle of 21°30', transverse pressure angle of 20°, and JIS grade N6 precision meeting JIS B1702-1:1998. Includes 10 mm hub width, 72 mm outside diameter, 18 mm total length, and allowable torque of 35.2 N·m (bending strength) and 68.9 N·m (surface durability). Backlash ranges from 0.10 to 0.18 mm. Axial thrust forces are generated during operation. Secondary operations on tooth areas are prohibited due to induction hardening. The part number KKHG1-70RJ14 includes an unlisted suffix; summary reflects the base KKHG1-70R series.

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.
