(1) According to the lubricating state, the iron ball bearing ball bearings can be divided into non-liquid friction sliding bearings and liquid friction sliding bearings.
Non-liquid friction iron powder ball bearing sliding bearing is in the shaft diameter and bearing surface, due to the adsorption of lubricating oil to form a thin layer of oil, known as the boundary oil film, which makes the shaft diameter and the bearing surface part of the direct contact, The other part is separated by the oil film without direct contact, thus reducing the friction coefficient of the sliding surface.
Liquid friction iron powder ball bearing sliding bearing is a thick lubricant layer on the shaft diameter and bearing surface, and the sliding surface is completely separated without direct contact. At this time, the friction on the sliding surface becomes the liquid friction inside the lubricant layer, and the friction coefficient is greatly reduced.
(2) According to the direction of the bearing load, it can be divided into radial bearings and thrust sliding bearings.
Iron powder ball bearings Centrifugal bearings commonly used radial bearings are mainly the following three types: Integral bearings, common integral bearings are in the machine frame out of the bearing hole, sometimes in the hole set with Bushing; Split bearing, which is a split type slide bearing, is bolted to the frame. Through the lubricating device on the bearing cover, the lubricant can be sent to the surface of the shaft diameter; the self-aligning bearing has a spherical surface formed on the outer surface of the bearing, and can be appropriately rotated on the corresponding spherical surface of the bearing cover and the bearing housing. In order to accommodate the axis deflection caused by axis deflection.
Iron powder ball thruster thrust sliding bearings thrust bearings are mainly subjected to axial force, it has two kinds of horizontal and vertical.
