Design of Jet Control Device for Forced Lubrication System of Bearing
Abstract In response to the problem of poor lubrication effect and unstable bearing operation leading to bearing failure in traditional bearings, the solution of installing a jet device on the bearing has been proposed. Using numerical calculation software, analyze the impact of installing a semi-circular or 1/4 circular jet device on ...

Generalized analytical equations were developed that accurately predict the local pumping characteristics, viscous dissipation, and average shear rates in channels of both conventional and high‐performance single‐screw extruders. Applied within segmented extruder calculations, these models aid in screw design and process troubleshooting without the ...

Growth of Subsurface Fatigue Fractures in Large‐Size Bevel Gears
ABSTRACT Large‐size bevel gears are commonly used in marine industry for the applications of propulsion, such as azimuth thrusters. The gears are typically designed for specific use, as they are directly transferring power from one component to another.
