KMBSA3-2030L is a left-hand spiral bevel gear with a module of 3, 20 teeth, and a finished bore, designed for power transmission. It is made of SCM415 steel with overall carburizing heat treatment, achieving a tooth hardness of 55-60 HRC. The gear adheres to JIS B 1704:1978 grade 4 precision, with a 20° pressure angle and 35° helix angle. It has a bore diameter of 21 mm, an outside diameter of 65.58 mm, a total length of 32.5 mm, and a face width of 21 mm. The mounting hole pattern is two M5 threaded holes spaced 6 mm apart. Secondary machining is prohibited due to case hardening. The allowable torque is 0.46 N·m under assumed usage conditions.
Module 3, 20 Tooth Left 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.
