The typical structure of the sliding bearing
  1. Integral radial sliding bearing structure
    
    Advantages: simple manufacturing process, stiffness, cheap, but the installation is not convenient, you can not adjust the wear and tear, only add reaming sleeve. Used for low-speed light-load machine.
    
    2. Off radial sliding bearing structure
    
    Features: Adjustable wear and tear, easy to install, can withstand small axial force.
    
    3. Sleeve bearings with a tapered surface
    The outer surface of the conical surface (1:30 ~ 1:10) as the inner surface of the cylindrical surface
    For example: machine tool spindle bearings. By adjusting the position of the sleeve relative to the shaft to adjust the bearing clearance.
    4. Self-aligning bearing
    An elongated shaft or pivot shaft, large deformation under load, the larger the journal bearing eccentric wear caused by the length of time, for automatic adjustment of the bearings.
    5. According to the principle of dynamic pressure bearing design bearing
    (1) oval bearing and more oil wedge bearing
    Features: bearing oil film stability and stiffness.
    (2) tilting pad bearing segments
    Segments supported at the rear end of the adjusting screw sphere, according to the elastic deformation of the shaft speed and load, deflection, etc. to ensure adequate clearance between the journal and the shaft, so as to form a liquid lubricant film.
    Features: idling can have the carrying capacity of the formation of several oil wedge, wedge reaction forces these oils help stabilize the shaft operation.
    Second, the thrust sliding bearing
    Axial load and prevent axial displacement of the shaft.
    1. Fixed thrust bearing
Use of hollow-type machine; polycyclic, can withstand axial load
    2. Tilting fan thrust bearing
    20 to 30 segments, supported on spherical or cylindrical, segments of steel back, sliding surface complex to bearing materials
