What is the material of automobile engine gear?

What is the material of automobile engine gear? Engine gear belongs to camshaft, which is usually forged with high-quality carbon steel or alloy steel, and can also be cast with alloy cast iron or nodular cast iron.

Camshaft toothed pulley is a widely used powder metallurgy part in various automobile engines. Through one-step molding and finishing process, the dimensional accuracy requirements, especially the tooth profile accuracy, can be completely met without other post-treatment processes. Therefore, compared with the traditional processing method, the material input and manufacturing are greatly reduced, which is a typical product embodying the characteristics of powder metallurgy. Name of matching parts: automobile engine; Camshaft, crankshaft timing pulley, water pump, oil pump pulley, driving and driven gear, driving and driven sprocket, cam, bearing cover, rocker arm, bushing, thrust plate, valve guide, intake and exhaust valve seat automobile gearbox; Various high-speed and low-speed synchronizer hubs and components, clutch gears, cams, camshafts, sliders, shift levers, shaft sleeves, guide blocks and synchronization rings.

Camshafts are usually forged by high-quality carbon steel or alloy steel, and can also be cast by alloy cast iron or nodular cast iron. After heat treatment, the working surfaces of journal and cam are polished. Most of the traditional camshafts are produced by casting or forging, and some of them are made by cutting carbon steel. Cast camshafts mainly include chilled cast iron and quenched cast iron. In order to reduce the weight, some camshafts are cast with cores to make the shafts hollow. In recent years, various types of camshafts have been developed, such as remelted chilled cast iron and quenched ductile cast iron, but due to cost and other reasons, their application scope is limited to individual fields.
