The KKHG3-25RJ35 is a precision ground helical gear with a module of 3 and 25 teeth, designed for right-hand rotation. It features a finished bore of 35 mm, making it suitable for various applications requiring precise motion transfer. 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 gear's specifications include a transverse pressure angle of 20¬8 and a helix angle of 21¬830'. The allowable torque for this gear is 258 N¬?m, with a corresponding weight of 1.12 kg. Backlash is specified between 0.12 to 0.22 mm, ensuring minimal play in gear engagement. This gear is part of a series that includes both right and left-handed variants, although it is not interchangeable with KSH type helical gears. The KKHG3-25RJ35 is suitable for applications that require high precision and durability in gear 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.
