Practical Example of Modification of a Gearbox Lubrication System

open access: yesLubricants, 2022
This paper presents the optimization of the lubrication method of a helical bevel gearbox, which is part of a pickling line. The first gear stage of this gearbox showed frequent failures. The bevel gearing and bearings were damaged.

Acoustic measurement of lubricant-film thickness distribution in ball bearings [PDF]

open access: yes, 2006
An oil-film thickness monitoring system capable of providing an early warning of lubrication failure in rolling element bearings has been developed. The system is used to measure the lubricant-film thickness in a conventional deep groove ball bearing ...

Air cushioning with a lubrication/ inviscid balance [PDF]

open access: yes, 2003
The air cushioning effect in the gap between an almost inviscid body of water and a nearby solid wall (or another body of water) is studied theoretically and is found to depend on predominantly lubricating forces in the air, in certain applications.

Lubrication system of a roller cone bit [PDF]

open access: yesMATEC Web of Conferences, 2020
For drilling roller bits that work with face purging, a device for a circulating lubrication system is proposed through the use of a plunger pump. A constant circulation of the lubricant is realized with a performance proportional to the speed of the bit.
