As a key mechanical component, oil film bearings play a vital role in the industrial field. Its working principle is to form a continuous oil film between the journal and the bearing through lubricating oil, thereby isolating the direct contact between metal and metal to achieve the purpose of reducing friction and wear. There are many types of oil film bearings, which can be divided into multiple categories according to different classification Стандарти .
From the perspective of lubrication, oil film bearings are mainly divided into hydrodynamic oil film bearings and hydrostatic oil film bearings. Hydrodynamic oil film bearings rely on the oil wedge effect generated when the journal rotates to generate sufficient pressure in the bearing oil film to support the load. This type of bearing has a simple structure and is easy to use. It is widely used in various types of rotating machinery. The hydrostatic oil film bearing uses an external oil supply system to force the lubricating oil with a certain pressure into the bearing gap to form a stable oil film. This type of bearing has the characteristics of high load-bearing capacity and good stability, and is particularly suitable for heavy loads, high speeds or high precision Поводи .
According to the different lubricating media, oil film bearings can also be divided into two categories: oil lubrication and water lubrication. Oil-lubricated bearings use lubricating oil as the lubricating medium, have good lubrication and heat dissipation properties, and are suitable for various working conditions. Water-lubricated bearings use water as the lubricating medium, have the advantages of environmental protection, energy Спестяване и дълъг живот и са особено подходящи за случаи с изобилие от водни ресурси или високи изисквания за опазване на околната среда .
В допълнение, лагерите на маслените филми могат да бъдат разделени и според индустрията на приложенията и специфичната структура ., например, в металургичната индустрия обикновено се използват лагери на мелници и лагери за минни машини; В аерокосмическото поле маслените филмови лагери трябва да отговарят на по -строгите високо температурни и високоскоростни изисквания за производителност .
Диверсифицираната класификация на лагерите на маслените филми отговаря на диференцираните нужди на различни индустриални полета за изпълнение на носенето, насърчава непрекъснатото развитие на индустриалните машини и осигурява надеждна механична поддръжка за всички сфери на живот .
