Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology. February 08, 2016 This paper proposes a new method for measuring normal interfacial stiffness. The contact interface is traditionally equivalent to some springs, but this general equivalent method is proved not sufficiently accurate in processing the elastic-plastic rough contact. The improved interfacial equivalent method is presented to remove the inaccuracy by introducing a contact layer, which considers the plastic zone beneath the rough surface , cited: Micro/Nanotribology and Its download online Micro/Nanotribology and Its Applications.

The cantilever will twist as the probe interacts with the surface while scanning. In an AFM it is possible to simultaneously measure topography and frictional force images. The topography image is derived from monitoring the vertical forces on the cantilever and the friction image is acquired simultaneously by monitoring the lateral motions of the cantilever Advances in Powertrain read online old.gorvestnik.ru.

Two kinds of textured discs were tested; the oil pockets were positioned in spiral and radial arrays the number of oil pockets within friction track also varied. It was found that in conformal contact conditions the presence of dimples resulted in considerable decrease of the friction force compared to untextured samples , cited: Bearings (Tribology Handbook) download pdf britwayz.org. To study the interface, the contact was investigated applying micro-pin-on-disk tests without grease or oil lubrication. As pins sapphire half-balls and 100Cr6 steel bearing balls were used.

When the bonds break portions of the material are transferred to the counterface. This process includes disappear of some of the interfacial surface and creation of a new surface. The balance of the surface energies determines the adhesive wear process. The effect of the surface energy on the coefficient of friction is also explained by the formation and disruption of the adhesive bonds between the rubbing surfaces Leeds-Lyon Symposium on Tribology: Running-in Process in Tribology 8th: Proceedings http://britwayz.org/?library/leeds-lyon-symposium-on-tribology-running-in-process-in-tribology-8-th-proceedings.

Hypoid gears the axis perpendicular or just offset? Why there will be more sliding in this gear? Ans: Hypoid gears are type of spiral bevel gears (bevel gear with helical teeth) whose axes do not intersect with the axis of the meshing gear. In other words axes of pair of hypoid gears are perpendicular (generally, angle may be other than ninety degrees) with an offset , e.g. Principles of Tribology download for free http://old.gorvestnik.ru/library/principles-of-tribology.

It is shown that viscoelasticity raises film thickness in a start of the motion and lowers the velocity at which the lubricant moves through the contact. This velocity is lower than the entrainment velocity in the first half of the contact, as in the experimental results with point contact , source: Handbook of Tribology: download online download online. The study at room temperature is also carried out for comparison. The friction and wear characteristics in sliding contact are evaluated and the worn surfaces are analysed through a scanning electron microscope. The experimental work indicates that wear resistance of laser hardened steel is five times higher than the as-received steel Energy Technology read pdf read pdf.

For product engineers who aim to control and optimize the sensorial properties of a product surface interacting with the skin, it is essential to understand this frictional behaviour. However, the friction of skin is yet poorly understood , e.g. 2005 Proceedings of the Asme read for free read for free. It was demonstrated that the bearing life of Cx-S wasn’t as long as urea grease, although it had excellent anti-oxidation performance. Additionally, leakage rate was calculated by the amounts of leaked grease from bearings during the test. Therefore, it was suggested that a physical factor such as shear stability of the grease is likely to cause shorter bearing life. Then, by using behenic acid instead of stearic acid - to improve shear stability of Cx-S - it was found that behenic type calcium complex grease (Cx-B) forms much thicker and stronger fiber micelles than stearic type (Cx-S) Tribology of Hydraulic Pump Testing (Astm Special Technical Publication// Stp) http://old.gorvestnik.ru/library/tribology-of-hydraulic-pump-testing-astm-special-technical-publication-stp.
