Q: What kinds of checks should be carried out for the design of non full liquid friction sliding bearings? Explain why, what does the PV value mean?: PV is the product of a certain bearing and bearing in line speed conditions and the PV value is inversely proportional to the service life of the bearing;

Q: Sliding bearings relative clearance 0.001 what?: The so-called relative clearance, refers to the sliding bearings of the Bush and bushings, nominal size tolerances can be large or small, but the gap between each other can only be 0.001.

Q: What are the structural and functional differences between thrust bearings and radial bearings and conventional ball bearings and plain bearings?: First of all, there is a classification error in the question you ask. The thrust bearings and radial bearings are separated according to the direction of the bearing force of the shaft. The ball bearings and the sliding bearings are separated according to the bearing structure,

Q: What are the failure modes and design criteria for non liquid friction sliding bearings?: Boundary film rupture, surface collapse, surface wear. Ensure that the bearings have sufficient fatigue life and limit the permanent plastic deformation of the bearings.

Q: sliding bearing: Because the sliding bearing no noise, and is generally used for low speed and heavy load conditions, or maintenance and operation of the site maintenance and lubrication difficulties, rolling bearing noise, complex structure, high cost, the structure is not the same

Q: What are the tolerances and finishes for plain bearings and shaft mating surfaces?: 1, the types of tolerance fit into three categories: gap fit (formerly called: dynamic coordination), transition coordination, interference fit (formerly known as: static coordination).2, clearance fit - the shaft and hole there is a clear gap between the coordination, the shaft can be turned in the hole3, the interference fit - there is no gap between the shaft and hole, the shaft and hole close together, the shaft will not be able to rotate alone4, transition coordination between gap fit and interference fit, there may be a gap, there may be interference, such coordination can be used as a precise positioning of the coordination5, when the need to rotate in the hole, choose clearance fit, require relatively large gap H11/c11 (such as: hand mechanism), requirements can rotate, and the gap is not too large demands on the choice of H9/d9 (such as: the idle band with the wheel and shaft), even if the gap with precision select the H8/f7 (such as sliding bearing with)6, if you want the shaft and hole fixed together to rotate, rotate together, to bear the load together with the load, can choose the fit, with little surplus amount can pass relatively small force, relatively large force will make the axis of rotation and hole assembly can be used wooden percussion hammer assembly. With type H7/n6, with large interference can express great force and general press assembly, or by the temperature difference method for assembly, for example: with the train wheel rim and hub, is to use the temperature difference method for assembly interference fit with type H7/z67, the need for precise positioning, but also need to be able to disassemble, such as rolling bearings, inner ring and shaft coordination, outer ring and hole fit, you can choose H7/js6, or H7/k6Hope that the above can help you

Q: How does a sliding bearing move at work?: When sliding bearings work, sliding friction occurs; the magnitude of rolling friction depends mainly on the manufacturing accuracy; and the size of the sliding bearing friction depends mainly on the material of the sliding surface of the bearing. Plain bearings generally work with self lubrication functions; plain bearings are divided into non-metallic sliding bearings and metal sliding bearings in accordance with material.Sliding bearings (sliding, bearing) bearings that work under sliding friction.

Q: How to distinguish sliding bearings and rolling bearings?: Rolling bearings are relatively moving parts with rolling bodies for rolling bearings.

Q: How to choose the aspect ratio of plain journal bearings: When the width to diameter ratio is too large, the bearing width is large, which makes it easy to cause serious wear on the journal and bearing.
