KMBSA4-4020R is a spiral bevel gear with a module of 4, 40 teeth, right-hand helix, and a finished bore, designed for power transmission. It uses SCM415 material with overall carburizing heat treatment, yielding a tooth hardness of 55-60 HRC. The gear meets JIS B 1704:1978 grade 4 precision standards, has a 20° pressure angle, and a 35° helix angle. It features a bore diameter of 60 mm, outside diameter of 160 mm, total length of 110 mm, face width of 28 mm, and a hub width of 60 mm. The gear is secured with taper pins and includes two tapped holes for mounting. The allowable torque capacity is 47.5 N·m for bending and 57.5 N·m for surface loading. Secondary machining is not permitted due to case hardening.
Module 4, 40 Tooth Right Handed Alloy Steel Spiral Bevel Gear with Finished Bore
Bevel gears are conically shaped gears produced as straight, spiral, and zerol bevel gears. The gears are commonly mounted on shafts that are perpendicular to each other. They are used to transfer mechanical energy between intersecting shafts. The shaft angle can be any angle, but bevel gears are typically used to transfer power at 90°, and the teeth are milled to interlock. As a bevel gear manufacturer, SDP/SI produces bevel gears using the Gleason® / Coniflex® (cutting) manufacturing methods.
Bevel Gears Industries & Applications
Bevel gears are used in a variety of industries, including aviation, robotics, defense, automobiles, and the railroad industries. They can be found in industrial mixers, cooling towers, printing presses, hand drills, garage doors, and forklifts, to name a few.
To satisfy customer needs and help move projects forward more efficiently, SDP/SI is a bevel gear manufacturer who offers stock inch and metric bevel gears in steel, stainless steel, aluminum, brass, nylon, and acetal; 72 pitch to 16 pitch and modules 0.5 through 8; ratios of 1:1 to 5:1 with higher ratios available upon request.
