Description of the design and purpose slide bearing, as well as the reasons for its failure.
Plain bearing – what is it?
With plain bearing many faced, because such products are used in the design of many devices. made their, depending on the load, of different materials, from conventional plastics and high-strength steel finishing. The meaning of this assembly is to ensure that with the help of free rotation between the two surfaces thereby, to avoid contact between a.
Due to the absence of contact and thus friction, parts and accessories, design which is provided a bearing, practically not subject to wear and tear. The exception in cases, when oil is filled with an admixture of abrasive particles. These particles damage the surface of bearings and soon they will have to be replaced. Plain bearings can be purchased at any specialized shop, например в интернет магазине подшипников и ремней https://2rs.com.ua/. There is a wide range of spare parts, everything FAG bearings of 2RS They are of high quality and are guaranteed.
Design features
Рассмотрим особенности на примере подшипника для коленчатого вала. Так как коленчатый вал испытывает высокие нагрузки, and the plain bearings are made of high strength steel for him, but provided that the inner side coated with a softer material. Such coating is required to keep the surface of the crankshaft without damage. Consequently, it acts as a protection, because in contact with engine oil grit between the crankshaft and the bearing surface, they are pressed into the soft layer of the last. Therefore, the bearings fail more often, than the crank shaft itself.
It is worth dwelling on the design features possessed by the crankshaft bearings. The fact, Such bearings, unlike a standard type, divided into two halves. So designers had to make because of the specifics of the installation on the crankshaft. However, it does not worsen their technical qualities and they are doing their job perfectly.
note! Sliding bearing surfaces in such contact occurs without the expense of the oil layer, for which admission to the upper part there are special technological grooves.
Causes of failure
from all, what has been said above, can understand, that the main cause of breakage of the crankshaft inserts protrudes engine oil of poor quality. Usually, This high degree of oil contamination grit, that during operation of the engine accelerates wear of sliding bearings. And when the car owner trying to save more and the oil filter, then the probability that the crankshaft bearings slip will break down even more increases. But if this still does not change the oil in a timely manner, then the probability that it will take a serious auto repair increases significantly.
Even when using the best quality oil brand, it is recommended not to save on the cost of the oil filter. To change it in a timely manner and not to hope, that it can last for a few necessary replacements. Then the life of the inserts will also be increased.
