GB/T 4662-2012/ISO 76.2006IntroductionRolling down the middle over the role of static load, its rolling element and raceway will cause permanent deformation, increase the amount of deformation with load Increases. For each specific application the choice of bearings, if the bearings through a lot of tests to determine whether the deformation bearings allowed Xu's words, which are often unrealistic, and therefore need to use other methods to determine the applicability of the selected bearing. Experience has shown that, bearing in most applications, the maximum load of the rolling elements and raceway contact center allows a rolling body diameter 0.0001 times the total amount of permanent deformation, it would not have a detrimental effect on the future operation of the bearing. Thus, this size will cause a permanent change Shaped amount equivalent static load rating is defined as static load bearing. Experiments show that the basic static load rating can be considered to be in contact with the following calculation produces the maximum load the rolling elements and raceway contact center Corresponding to the load force. --- 4600MPa1) aligning ball bearing; --- 4200MPa All other ball bearings; --- 4000MPa all roller bearings. Formulas and coefficients basic static load rating of these are based on contact stress. Depending on the smooth running and friction requirements and the actual geometry of the contact surface, allowing the equivalent static load optional small Than, equal to or greater than the rated static load. This lack of experience, bearing the user should consult the bearing manufacturer. 1) 1bar = 0.1MPa = 105Pa; 1MPa = 1N/mm2. GB/T 4662-2012/ISO 76.2006 Rolling static load rating1 ScopeThis standard specifies the method for rolling bearing calculation Basic static load rating and equivalent static loads. This standard applies to the extent consistent with the size there Relevant national standards, the use of conventional high-quality hardened bearing steel, manufactured in accordance with good processing method, and the rolling contact surface shapes substantially Conventional design bearing. This standard does not apply to the use of conditions or (and) bearing internal structure caused Rolling ring raceway contact area of \u200b\u200bsignificant truncation Bearings, should according to this standard, you can not get satisfactory results. Also, the standard does not apply to the use of conditions that cause bearings In case of deviation from normal load distribution, such as tilt, excessive preload or clearance surface been treated or coated, etc. If these Case, the user should consult with the manufacturer on how to calculate equivalent static bearing load. This standard is not applicable to the rolling elements in the bearing surface of the shaft or operation of direct structures, unless they surface in all respects it Instead of bearing ring raceway surface considerably. For double row bearings radial bearings and thrust, should refer to this standard shall be assumed to have the structure symmetry. In addition, this standard also applies to the static safety factor under heavy load conditions determine.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated edition applies to this article Member. For undated references, the latest edition (including any amendments) applies to this document. ISO 5593 Rolling vocabulary (Rolingbearings-Vocabulary) ISO 15241 Rolling Parameter Symbol (Rolingbearings-Symbolsforquantities) ISO /TR10657.1991 Dui ISO 76 Notes (ExplanatorynotesonISO 76)3 Terms and DefinitionsISO 5593 define the following terms and definitions apply to this document. 3.1 Static load staticload Washer or bearing rings relative to each other when the speed is zero, the load acting on the bearing. 3.2 Basic radial static load rating basicstaticradialloadrating Radial contact stress following calculation corresponding to the maximum load of the rolling elements and raceway contact at the center of static load. --- 4600MPa aligning ball bearings; --- 4200MPa other types of radial ball bearings; --- 4000MPa radial roller bearings. Note 1. For single row angular contact ball bearings, radial static load rating refers to the cause of the bearing rings radial component of load mutual pure radial displacement. Note 2. In static load conditions, these refer to the contact stress caused by the rolling element and raceway generated total permanent deformation of approximately 0.0001 times the diameter of the rolling element when stress. 3.3 Axial basic static load rating basicstaticaxialloadrating It produces the following calculated contact stress corresponding to the maximum load in the center of the rolling elements and raceway contact at the center of the axial static load.
