KMBSA3-4518R is a spiral bevel gear with a module of 3, 30 teeth, and a right-hand helix, designed for power transmission. Made from SCM415 steel with carburizing treatment, it achieves a tooth hardness of 55-60 HRC and complies with JIS B 1704:1978 grade 4. It has a 20° pressure angle and 35° helix angle. The gear has a finished bore, hub diameter of 65 mm, pitch diameter of 135 mm, outside diameter of 136.24 mm, and face width of 37 mm. Mounting is via a B4-type configuration with two M6 tapped holes. Allowable bending strength torque is 234 N·m (23.8 kgf·m); surface durability torque is 256 N·m (26.1 kgf·m). Backlash ranges from 0.08 to 0.18 mm. Total length is 92.96 mm, crown-to-back length is 11 mm, and weight is 3.92 kg. Secondary machining is prohibited.
Module 3, 45 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.
