S13S4YMK20G45R12 is a metric spiral bevel gear with a module of 2, 20 teeth, and a 1:3 ratio, designed for power transmission between perpendicular shafts. It features a 35° spiral angle, a 20° pressure angle, and an induction-hardened AISI 1045 steel tooth surface with HRC 48-53 hardness. The gear has a black oxide finish, a 12 mm bore diameter, a 45 mm face width, and a 102.44 mm pitch diameter. The tooth profile is left-hand helix as indicated by the 'L' in the catalog number. Physical dimensions include a hub diameter of 78.59 mm and a hub length of 40 mm.
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.
