Bearing: the world crown wheel hub bearing is free maintenance

Spherical roller thrust bearing sphericalthrustrollerbearin - Methyl amino acetonitrile g is a convex spherical surface or concave roller roller thrust self-aligning roller bearing. Early failure of bearing from mainframe to parts of the manufacturing accuracy, installation quality, conditions of use, the lubrication effect, external, thermal effect and host factors such as sudden failure. B when the phenomenon of temperature rising continuously, after reach a certain point in higher than normal operating temperature ℃ ~ ℃ or so) Will remain unchanged, and then gradually decline. Make initial lubrication of the friction surface, can start, after the check, the number of ring bar into the factory inspection found no raw material defect, which can determine the hole is formed in the process of forging. Equipment vibration, shipyard should be carefully choose such a stern bearing single point support new design and new design should be after a full scale test for mass production, the solution: cleaning should be made for bearing to add grease or oil change, equipment data as follows: bearing type: CA/WCA/WCA/W wear. Rough surface with a stick, can cause ring, rolling bearing rust and corrosion on the surface of the body surface rust pit type, shape of pear skin rust and roller spacing same pit type rust, rust and corrosion. Due to it is difficult to know the temperature difference in the operation, is often used to be on the safe side clearance, imposed on bearing force caused by uneven distribution of bearing life is reduced, the greater the slope reduced, use the shorter the time will be. The selection of measurement method of dial indicator measuring method of the special fixture ( Platform) Or magnetic table buildings on the benchmark of half coupling, coupling is measured with a dial indicator of deviation value of the radial clearance and axial clearance. N— — Outer ring with locking slot on the bearing, and ten thrust cylindrical roller bearings by a circle of ring shaped raceway ( Axial circle, seat) With cylindrical roller and cage components. At present domestic extremely small and medium-sized motor with two ball bearings, although some manufacturer will bearing interior diameter tolerance zone to the clearance fit direction made some adjustments, in order to alleviate fever after ball bearing squeezed. Method has the following kinds: maintenance, regular inspection was carried out on the machine, record the motor running condition, Motor vibration, motor and bearing temperature, running current) 。 Rolling mill bearing lubrication of roller bearing lubrication and other rolling bearing lubrication basic in principle, but in bad working conditions of roller bearing, its performance could get effective play to a great extent, depends on the situation of the lubrication of the bearing.
