Slewing bearing failure analysis in its actual running often appears with some faults such as overload, abnormal impact, groove wear, noise, material properties, subsurface stresses. This paper mainly analyzes the causes of the faults from three aspects of the bearing's installation mode, its load condition, and its lubrication maintenance. So the solution is putted forward to improve the slewing bearing's accuracy.
The supporting surfaces must have a flat machined surface and be rigid enough to eliminate torsional buckling under load that would affect the smooth operation of the single row ball slewing ring bearing. The thickness of the supporting plates should be no less than that indicated below – which is offered as a rough approximation only.
As supplied slewing rings are generally packed for storage in a covered store and for a period notexceeding 6 months. Light surface corrosion can usually be removed from exterior surfaces – and it is more important that the raceways are well greased and rust free. Standard commercial solvents can be used to degrease the slewing ring if necessary.In extreme cases after long term storage bearings may need professionally reconditioning before installation.When unwrapping, care must be taken not to cut and damage the integral seals.
The single row crossed roller bearing is composed of two seat rings, which design in compact structure and light weight, the clearance is small when assembly, so need high precision. The roller is 1:1 cross arranged, it can bear the axial force, tilting moment and relatively large radial force.
It is widely used for hoisting,transportation, construction machinery, and the military products.Double row ball slewing bearing has two row rolling balls (with same size), which can bear big axial load, radial load and tilting moment. Safety factor is higher.It can used for different cranes, mining equipment, excavators etc.
The three row roller bearing has three seat rings, which separate the upper, lower and radial raceways, it made each row of the roller’s load capacity can be specified and can bear different loads simultaneously. The capacity load is the largest one compare with the other three models.
