Conjunction gears, which are also known as helical gears with clutch gears, are used mainly
in the transmission and shift design of automobile gearboxes. In this paper, focusing on the …

Non-circular spur bevel gear (NCSB-gear) is a kind of special spur bevel gear which can
perform variable speed ratio transmission. It can achieve several special functions which …

We present a practical approach that improves the accuracy of finite element predictions of
hot forging; we emphasize the importance of tribological characterization. We analyze three …

An EA4T steel billet was forged at the different initial forging temperatures (1050, 1150, and
1250° C). The microstructure and fatigue fracture of forged samples were observed by laser …

The ultrasonic contact impedance technique and ultrasonic wave velocities have been
widely used for non-destructive hardness measurement. Ultrasonic wave velocity shift …

As an important transmission component, the spur gear has been widely used in
automobiles and various mechanical equipment. However, spur gears are usually produced …

The railway wagon bogie adapter is a critical component in train operation, with stringent
quality requirements. Microstructure uniformity is an effective method for improving adapter …

The casting of metal alloys followed by hot forging is a widely used manufacturing
technology to produce a homogeneous microstructure. The combination of mechanical and …

Due to the non-uniform dynamic recrystallization (DRX) and deformation behavior during hot
forging process, the spur bevel gears tend to receive heterogeneous microstructure which …

The microstructure of a material can strongly influence its properties such as strength,
hardness, wear resistance, etc., which in turn play an important role in the quality of products …
