The KKHG1.5-70LJ30 is a precision helical gear with a module of 1.5 and 70 teeth, designed for left-handed applications. It features a finished bore of 30mm, allowing for easy integration into various mechanical systems. 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 helical gear has a transverse pressure angle of 20¬8 and a helix angle of 21¬830', ensuring smooth operation and efficient power transmission. The allowable torque for this gear is 114 N¬?m, making it suitable for applications requiring reliable performance under load. Backlash is specified between 0.12 to 0.20 mm, which is critical for maintaining precision in gear meshing. This product is ideal for engineers seeking durable and high-performance helical gears for their projects.

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.
