Non-standard bearings commonly used three practical maintenance methods at ordinary times? Source: bearing | last updated: - 2020 10 - 14 non-standard bearings commonly used three practical maintenance methods at ordinary times? Non-standard bearings when bearing show the problem, the first idea should be query service, rather than want to swap. General bearing maintenance type has the following three kinds: 1, the problem of maintenance: on the problem of bearing, query and maintenance. 2, timing, perform maintenance: in order to guarantee the normal work of the server everything, according to the regulation of the server and an introduction to the design of the bearing and application after, set up a maintenance cycle time, perform maintenance regularly. 3, early warning information maintenance: the leading non-standard bearing problem diagnosis of professional skills, the application situation of real-time monitoring system of bearing, on the problem of bearing made clear before trailer, carry out maintenance. Bearing in the working process, there must be the phenomenon such as noise, temperature, and turbulence. As a result, the bearing in the work to carry out the maintenance maintenance, can be after hear, touch, and application of bearing diagnosis instrument equipment problem found bearing abnormal changes, according to the circumstance of change can identify bearing in normal working condition. Non-standard bearing torque, load and the service life of the 1. The starting torque made a non-standard bearing ring or seal relative to a stationary ring or seal first rotation needs of torque. 2. Rotational torque when a non-standard bearing ring or sealing ring rotates, blocking the other ring or seal fitness needs of torque. 3. The axial load effect on the vertical non-standard bearing pivot line bearing load. 4. Radial load effect on parallel surface of non-standard bearing pivot line bearing load. 5. Static load when the cast non-standard bearing ring or seal the relativity of the rotation rate is zero, Radial torque or non-standard bearing) Or when the flip components in reverse bearing no fitness ( Parallel lines of non-standard bearing) , the effect on the non-standard bearing load. 6. Dynamic load when the cast non-standard bearing ring or seal relativity turns ( Radial torque or non-standard bearing) Or when the flip components in reverse directions fitness ( Parallel lines of non-standard bearing) , the effect on the non-standard bearing load. 7. Dose load calculation theory in general terms, in special places, non-standard bearings based on the theory seems to assume the specific load under the load effect. 8. The axial ( Radial) Rating based on the static load and turn the swivel and the total permanent variable of dovetail guideway relativity should axial static load ( Management center of radial static load) 。 If under zero load, roller bearing and dovetail guideway ( Roller bearings non-standard bearings) For or assumed for all normal bus duct ( The entire touch) , under the large contact pressure, double twist and dovetail guideway touch of total permanent variables for the diameter of 0. 0001 times. Touch the non-standard bearings for affairs Angle, axial load rating for the cause of non-standard bearing throw circle mutual relativity of pure axial deviation of the axial load weight. 9. The axial ( Radial) Basic dynamic load rating of the stability of the axial load, Stable management center radial load) , under the load, flip turn non-standard bearings can withstand 1 theoretically millions of basic rating life. Touch the non-standard bearings for affairs Angle, the axial load rating for the cause of non-standard bearing throw circle of mutual relativity of pure axial offset load weight. 10. The service life ( Refers to a set of non-standard bearing) Non-standard bearing a ring or a ring or a double twist before initial occurrence exhaustion development of raw materials, a ring or a ring of relativity in another ring or a ring of speed. Life can also be used in a given operation under the steady speed ratio of hours to show. 11. Credibility, The non-standard bearing service life) A group tend to be in the same standard run under the same flip non-standard bearings are looking forward to achieve or exceed a certain percentage of non-standard bearing requires the use of life. A set of non-standard bearing credibility so achieve or exceed the requirements of non-standard bearing the risk of life. 12. Rating service life based on the axial dynamic load rating or radial basic dynamic load rating for basic life estimate.
