The force of friction is directly proportional to the applied load. (Amontons 1st Law) 2. In this paper, the effect of defect size, operating speed, and loading conditions on statistical parameters of AE signals, using design of experiment method, have been investigated to select the most sensitive parameters for diagnosing incipient faults and defect growth on rolling element bearings.

Like the pour-point factor, the flash point may in some instances become the major consideration in selecting the proper lubricant, especially in lubricating machinery handling highly flammable material.

The affecting rule of both the slip-region location and the size on the load-carrying capacity is obtained. Only a well-designed slip surface could improve the tribological performances of hybrid journal bearings. This work could provide a valuable guide for the design of a slip surface in high-speed hybrid journal bearings.

A short-term rate of particle generation is sometimes used as an alternative; however, it too can be misleading with short succession particles producing high instantaneous rates possibly causing false alarms. The purpose of this work was to develop a robust metric (or group of metrics) that when applied to Inductive Wear Debris Sensor data would reliably identify a failure event and exclude non-failure related particles online. For maximum insulating properties, a lubricant must be kept free of contaminants and water. Lubricants also act as shock-damping fluids in energy-transferring devices (e.g., shock absorbers) and around such machine parts as gears that are subjected to high intermittent loads , e.g. Lubrication Fundamentals read pdf http://britwayz.org/?library/lubrication-fundamentals-mechanical-engineering.

So an effort has been made in this current research work to bridge the gap. To determine the cryogenic tribological behaviour of Al-TiCp composite, sliding wear tests are conducted. A customised cryogenic-tribo setup has been developed by attaching cryogenic system to pin-on-disc configuration. Nozzle arrangement to the cryogenic-tribo setup feeds cryogenic fluid (liquid nitrogen: LN2) exactly into sliding contact with a restricted flow rate and constant pressure for better cooling and lubrication , source: Tribology In read online britwayz.org.

In comparison with the existing slip models, such as the first, second, and 1.5-order slip models, the current slip model agrees well with F-K model over the entire flow regimes and therefore is expected to be more accurate for ultra-thin gas film lubrication at head-disk interface online.
