May 26, 2008 · After the forging process, the helical gear parts were heated up to 950 °C in the electrical oven and then quenched in the various cooling media. To obtain highly accurate heat transfer coefficient, a quenching experiment using a test specimen was carried out to measure the cooling curves for several points.
Cast Iron Types Metal Casting ResourcesA versatile metal, cast iron has many unique applications in the commercial and industrial world Cast iron has excellent castability due to the combination of high carbon content and silicon. The presence of iron in everyday life began in about 1200 BCE, encompassing a wide range of uses from farming implements to weapons of war.
Typical gear forgings. The 4.5 kg (10 lb) gear shown in Figure 8 was forged from 8620 steel billet 75 mm (3 in.) in diameter by 124 mm (4.9 in.) in length. An energy level of 353,000 J (260,000 ft · lbf) was needed to forge the gear in one blow at 1230 °C (2250°F).

Internal Gears KHK GearsInternal Gears used in mechanisms such as planetary gear drive. Internal gear is a gear with its teeth cut in the internal surface of a cylinder and meshes with spur gears. In its manufacturing, because of its shape, the usual hobbing machine used in spur gear production cannot be used.
Major difference of Internal vs External Spur Gears Internal spur gears are an integral part of planetary gear drives and gear couplings. AmTech International manufactures high quality internal and external spur gears of various sizes and dimensions, in high quality stainless steel and aluminum alloys, with custom manufacturing options to meet OEM customer needs.
Dec 01, 2014 · For the forging of a helical gear, it is difficult to obtain the punch movement in the guiding type forging, because it requires high forging load and high forging speed. Choi et al. (2000) investigated the cold extrusion of the involute spur gears with internal
