The primary function of rod seals in hydraulic systems is to prevent the leakage of the hydraulic medium, which would otherwise result in environmental pollution and the loss of energy. However, the leakage control performance ...

Improving the wear resistance of cone bit bearings is crucial for enhancing bit life and drilling efficiency. This study integrates surface texture lubrication with bit floating sleeve bearings. A ring-block friction ...

MoS2-based solid lubricants have obtained significant attention and are extensively employed in the aerospace industry due to their desirable tribological performance. However, to enhance their performance in humid ...

The slipper pair accelerated degradation test has a long cycle time, high cost, a lack of mechanism explanation, and cannot illustrate the correspondence of wear-rate under different pressures, and there is an urgent need ...

As modern devices and systems continue to advance, device wear remains a key factor in limiting their performance and lifetime, as well as environmental and health effects. Traditional approaches often rely on wear prediction ...

To satisfy the large-scale and high-power demands of wind turbines, planetary gear journal bearings (PGJBs) have been applied in large wind turbine gearboxes (WTGs), as an alternative to traditional rolling bearings, due ...
