KSH3-40L is a left-handed helical gear with a module of 3, 80 teeth, and a helix angle of 15°. It is made of S45C steel with a tooth hardness of less than 194HB, and meets JIS grade N8 (JIS B1702-1: 1998) precision standards. The gear has a pitch diameter of 124.23 mm, an outside diameter of 130.23 mm, a face width of 35 mm, and a total length of 50 mm. It has an allowable torque of 531 N·m for bending strength and 54.1 N·m for surface durability. The gear is designed for use in pairs with right-handed counterparts and produces axial thrust forces. Secondary operations that reduce tooth width are discouraged due to impacts on precision and strength.

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.
