KMBSB4-3020R is a 30-tooth, module 4, right-handed spiral bevel gear with a finished bore, made from SCM415 steel with overall carburizing and a tooth hardness of 55-60 HRC, conforming to JIS B 1704:1978 grade 4 precision. It has a pressure angle of 20° and a helix angle of 35°, with a pitch diameter of 122.91 mm, outside diameter of 135 mm, face width of 23 mm, and hub width of 10 mm. It uses two M8 mounting screws, with an allowable torque capacity of 33.5 N·m. No secondary machining is permitted after carburizing. The gear is designed for axial thrust load applications and requires secure mounting via taper pins, not solely screws.
Module 4, 30 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.
