Effect of temperature on the frictional behavior of 18CrNiMo7-6 under lubrication

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2022
In the process of gear meshing, the tooth surface will produce friction heat, which will in turn act on the friction coefficient. The temperature does not directly affect the friction coefficient of the gear tooth surface, but indirectly through ...

Simulation and Mechanical Properties of Fine-Grained Heat-Affected Zone Microstructure in 18CrNiMo7-6 Steel. [PDF]

Materials (Basel), 2022
Heat-affected zones (HAZs) in real welds are usually quite narrow, and consequently most standard mechanical tests are difficult or even impossible. Therefore, simulated microstructures are often used for mechanical tests. However, the most often used weld thermal cycle simulator produces only a few millimeters wide area of simulated microstructure in ...

Gradient microstructure and microhardness in a nitrided 18CrNiMo7-6 gear steel [PDF]

IOP Conference Series: Materials Science and Engineering, 2017
A commercial gear steel (18CrNiMo7-6) containing a tempered martensite structure was nitrided using a pressurized gas nitriding process under a pressure of 5 atm at 530 °C for 5 hours. The mechanical properties and microstructure of the nitrided sample were characterized by Vickers hardness measurements, X-ray diffraction, and backscatter electron ...

A comparative study on the dynamic behaviour of 10 MW conventional and compact gearboxes for offshore wind turbines

Wind Energy, Volume 24, Issue 7, Page 770-789, July 2021., 2021
Abstract This study compares the dynamic behaviour of a conventional and a compact gearbox for the DTU 10 MW wind turbine supported on a monopile offshore structure. The conventional gearbox configuration is composed of two planetary epicyclic stages and one parallel stage, while the compact gearbox configuration consists of a fixed planetary stage and
