Experimental Investigations to Use Splash Lubrication for High-Speed Gears
Journal of Tribology, 2017In order to use electric motors which run up to 40,000 rpm in future automotive applications, this study aims to experimentally investigate if splash lubrication technique is worth considering for high-speed gears, i.e., for tangential gear speed up to 60 m/s.

A novel passive filtration system for splash-lubricated gearboxes: Part 1
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2020Splash-lubricated gearboxes are widely used in many industries. Contaminant removal systems are rarely employed in splash-lubricated gearboxes, such as some gearboxes are used in helicopters and mining machines. The maintenance of lubrication systems in those machines relies on periodic onsite inspection and lubricant change.

Prediction of Oil Flow inside Tractor Transmission for Splash Type Lubrication
SAE Technical Paper Series, 2019<div class="section abstract"><div class="htmlview paragraph">This study introduces a method to examine the flow path of the lubricant inside a transmission housing of a tractor. A typical gearbox has several loads bearing elements which are in relative sliding motion to each other which causes heat to be released.

Journal of Tribology, 2021
Abstract Planetary gears are used in several applications given that they provide high reduction ratio in a compact size. Two kinds of lubrication are used in these applications: injection or splash lubrication. In case of splash lubrication, the authors already highlighted the importance of the centrifugal effects leading to the ...

Design and analysis of a passive filtration system for splash lubricated gearboxes
2020Lubricants are used in many applications to reduce frictions between contacting surfaces. Machines with clean lubricants will be able to achieve a longer life cycle and better reliability. It is unavoidable that wear particles and environmental ingress will be generated continuously during machine operating time.

International Journal of Heat and Fluid Flow
To systematically clarify the migration and evolution mechanisms of metallic particles in the solid-liquid-gas three-phase flow field of a helicopter intermediate reducer under splash lubrication, this study innovatively develops a three-phase numerical model based on the CFD-DPM framework, and establishes a high-precision oil-churning visualization ...

Flow and Heat Transfer Simulation in a Splash Lubricated Bell 525 Accessory Gearbox
Proceedings of the Vertical Flight Society 73rd Annual Forum and Technology Display, 2017Operating temperatures in a drive system gearbox are impacted by multiple factors like mechanical power, operating environment, geometrical design and lubricant properties. Cooling and lubrication performance is critical to operation and durability.

Analyses on the Splashing Parameters of High-Speed Oil Impacted a Wall in Jet Lubrications
2009A new model for the free jet breakup is derived from the TAB theory to determine the size of breakup in the energy conservation law. In addition, the splash behavior of droplets after impingement is determined by the newly proposed model, which incorporates both the size and the number models based on Wu Ziniu’s phenomenological theory.
