The KKHG1.5-100R is a ground helical gear with a module of 1.5, 100 teeth, and a right-hand helix. It features a bore diameter of 70 mm, a hub diameter of 150 mm, a pitch diameter of 150 mm, an outside diameter of 153 mm, a face width of 24 mm, a hub width of 12 mm, and a total length of 170 mm. The gear is made from SCM440 steel with induction-hardened tooth surfaces rated at 50 to 60 HRC. It meets JIS grade N6 (JIS B1702-1:1998) and JIS grade 2 (JIS B1702:1976) precision standards, has a transverse pressure angle of 20°, and a helix angle of 21°30'. The allowable torque is 554 N·m (56.5 kgf·m) based on bending strength, with a backlash range of 0.12 to 0.20 mm. Secondary operations on the teeth 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.
