42CrMo steel is widely used in ultrahigh-strength structures such as low-speed heavy-duty gears. Mastering the fatigue crack propagation law has important significance for predicting structural life. Firstly, experiment to obtain upper and lower thresholds value of type I compact tensile specimen under alternating load stress ratio R = 0.1. The Paris formula describing relationship between rate tip intensity factor obtained. Scanning electron microscopy was observe microscopic features...
Gear forming by cross rolling with local induction heating process is an alternative method to manufacturing large diameter gear parts, and the distribution of temperature has a great influence on subsequently process. To get satisfied heated workpiece, model coupling electromagnetic thermal field combing rotational motion established rate along axial circumferential been investigated. Moreover, corresponding experiment was carried out parameter were measured multi meter infrared...
Abstract Cross rolling process is a new method to manufacture large-diameter gears, which has great advantages. While during the gear manufacturing with cross rolling, due difference of deformation mechanism between right and left formed tooth profiles, tip pulled at top workpiece, severely affects forming quality. To eliminate occurred defect, finishing roller proposed designed, motion equation established solved, principle height increase obtained. And also simplified finite element (FE)...
With the development of net-shape forming technology, hot process is widely applied to manufacturing gear parts, during which, materials suffer severe plastic distortion and microstructure changes continually. In this paper, understand model flow behavior evolution, SAE 8620H, a used steel, selected as object evolution are observed by an isothermal compression tests at 1273-1373 K with strain rate 0.1-10 s−1. Depending on results test, set internal-state-variable based unified constitutive...
