3 friction lubrication and the pdf Tribology is the science and engineering of interacting surfaces in relative motion.it includes the study and application of the principles of friction, lubrication and wear.tribology is highly interdisciplinary. It draws on many academic fields, including physics, chemistry, materials science, mathematics, biology and engineering.people who work in the field of tribology are referred to as... Tribology - Wikipedia A lubricant is a substance, usually organic, introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. The property of reducing friction is known as lubricity. Lubricant - Wikipedia A constant contact between the friction surfaces at high surface points (microasperities) occurs at boundary lubrication. This regime is the most undesirable since it is characterized by high coefficient of friction (energy loss), increased wear, possibility of seizure between the bearing and journal materials, non-uniform distribution of the bearing load (localized pressure peaks). Lubrication regimes [SubsTech] The progressive lubrication systems allow oil or greas (up to NLGI 2) distribution to lubricate the friction points of the machines. The divider blocks of between 3 and 24 outlets guarantee a correct discharge for each point. Progressive Lubrication - ILC - Impianti di lubrificazione The friction loss sources of the average passenger car were identified and classified according to the tribological contact and lubrication mechanism. Global energy consumption due to friction in passenger Consider the equilibrium of a unit volume in the lubricant film. The pressure forces act on the right and the left faces of the unit volume. The shear forces resulting from the relative motion of the laminar layers act along the upper and the lower faces of the unit volume. Hydrodynamic lubrication theory [SubsTech] Dustproof design SS series-end seal The standard end seal design can be hermetically sealed and dustproofed. This extends the product lifespan, reduces lubrication grease consumption, cpc - chieftek Physics Lectures Index Lectures are in pdf format. Click here to download Adobe Reader..
