Module 2.5 right-hand ground helical gear made of SCM440 with induction-hardened tooth surfaces ranging from 50 to 60 HRC, featuring a 20° transverse pressure angle and 21°30′ helix angle, conforming to JIS grade N6 (JIS B1702-1:1998) and JIS grade 2 (JIS B1702:1976). The gear has 60 teeth, a pitch diameter of 150 mm, an outside diameter of 155 mm, a face width of 20 mm, a hub width of 14 mm, and a total length of 34 mm. Allowable torque is 890 N·m (90.8 kgf·m) based on surface durability, with backlash of 0.14-0.24 mm. The product generates axial thrust forces and cannot undergo secondary operations on tooth areas 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.
