Carburized gear grinding teeth molding applications processing aspects:
Typically gear final heat treatment method is carburizing, tooth surface hardness of HRC60 +/- 2, also provides a hardened layer depth requirements vary with the size of the modulus, good anti-wear contact strength, the tooth core section has a relatively low hardness and good toughness, flexural strength can be improved. Obtained after carburizing ideal surface residual stress, which can make the maximum tensile stress stress tooth area decreases. So part of the tooth root surface after heat treatment usually reserved for when to use the previous procedure hobbing toothed belt grinding leave antennae amount hob hobbing, grinding teeth so that will not rub off when the tooth root portion. Select the appropriate grinding wheel and cutting the amount of time, supplemented by cutting a large flow of coolant is an important measure to prevent teeth grinding cracks and burns appear. Gear ultrasonic testing, magnetic particle inspection and testing coloring, as well as the necessary metallographic examination, are effective measures to control the quality of the internal gear.
