Egyptian Parts

Posted by domain admin in News

The origin and bearing the name dates back to Egyptian times, when they moved the heavy and large objects for the construction of temples, pyramids. A recent excavation at the excavations was discovered the ship times of the Incas. At this ship was found the first semblance of bearings (movable shaft on the axis with many elements reminiscent of bearings of different sizes). In supporting parts of the various mechanisms and machines used bearings, which in turn further divided into two basic types: plain and rolling bearings. Plain bearings are building a cylinder with holes that are filled with inserts or sleeves of the antifriction material and lubrication device. Existing gaps between the shaft and the hole sleeve allow free rotating shaft. Also distinguish between types of bearings (type depends on the conditions of operation, construction details and the peripheral speed tap) – boundary, dry, liquid and gas dynamics.

This kind of bearings includes mandatory friction when sliding of mating surfaces. Also plays an important role lubrication, which divides the bearings hydrodynamics, gas dynamics, etc. For example, bearings are often used in generators and internal combustion engines. In such high antifriction bearings dominated resistance, which reduces the losses due to friction and reliability. With good as this type of bearing increase the resources and structures reduced the frequency of repair parts. Once again I would remind you about as a lubricant, which provides low friction, heat dissipation, a division of moving parts and resistance against adverse environmental impact.
