EN 12082:2007 (E) 4 Introduction This European Standa
25、rd has been drawn up with the purpose of standardizing the performance testing of axleboxes for all types of rolling stock to ensure suitability for the required service, i.e. that the assembly of box housing, bearing, sealing and grease is well suited for the service requirements. This testing is m
26、ade up of two stages, a “rig performance test“, described in detail in this European Standard, and a “field test”. When rig performance testing is specified, it needs to be carried out in accordance with this European Standard. The extent of testing to be applied depends on the novelty of bearing de
27、sign, seal design, grease formulation or box housing, as well as the application (see EN 12080 and EN 12081). The rig performance test will check the satisfactory function of the assembly during a simulated journey. It is to be applied only if the axlebox is composed of elements delivered by supplie
28、rs that operate a quality management system4). The field test comprises monitoring on vehicles in service of a sufficiently large sample of axleboxes during a high mileage. 4) The systems used should offer equivalence with EN ISO 9001. EN 12082:2007 (E) 5 1 Scope This European Standard specifies the
29、 principles and methods for a rig performance test of the system of box housing, rolling bearings, sealing and grease. Test parameters and minimum performance requirements for vehicles in operation on main lines are specified in Clause 6 and Annex A (normative). Different test parameters and perform
30、ance requirements may be selected for vehicles in operation on other networks. Basic principles for a field test are also determined. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

39、n EN 12080 and for the lubricating greases in EN 12081. The rig performance test is stipulated in both of these European Standards. For the rig performance test, the following is to be agreed between the customer and the supplier and shall be fully documented by the supplier: designation and charact
40、eristics of the rolling bearing according to EN 12080; designation and characteristics of the lubricating grease according to EN 12081; designation and characteristics of the sealing; designation and characteristics of the box housing; input data required for determining test parameters are further
41、described in 6.2.2; extent of testing for rolling bearings for vehicles not in operation on main lines; extent of testing for rolling bearing, grease, sealing or box housing similar to service proven designs (see A.5); conditions intended for the field test (see Clause 7). EN 12082:2007 (E) 7 5 Wate
42、rtightness test The customer shall specify whether a watertightness test shall be made. A suitable method (in static mode) is presented in A.9. A method for optional further dynamic testing is described in UIC 515-5. 6 Rig performance test 6.1 General The test consists of putting two axleboxes on a
43、test rig and subjecting them to repeated loading cycles determined from the operating conditions of the vehicles to be equipped with these axleboxes. Two identical axleboxes including; rolling bearings, sealing, grease and box housing, assembled as for operating conditions shall be mounted on the te
44、st rig axle journals. After mounting, the clearance shall be as close as possible to the maximum of the tolerance for one axlebox and minimum for the other. During rig operation, the axleboxes are subjected to constant vertical loads and varying transversal loads which will produce radial and axial
45、forces on the rolling bearings. Calculating the constant nominal radial force nr F and the nominal axial load an Fis carried out by means of the methods described in A.4. The constant radial load is designated r F, and the varying actual axial load is designated a F. All these forces are applied on
46、one journal with axlebox. Other test parameters including different radial and axial load cycles, speeds, bending forces on axle journal transmitted via the axlebox, analysis of temperature etc. can be applied as supplementary tests in agreement between customer and supplier. Before the real perform
47、ance test, a pre-test shall be carried out. This does not constitute part of the official approval test for the bearings or grease being tested, but is intended to observe the thermal behaviour of the bearings while the grease is redistributed. The performance test consists of repeating identical cy
48、cles up to an agreed cumulative distance. The number of cycles and the test distance reflect the service conditions of the intended application. Throughout the test, the performance of the bearings will be monitored by measurement of temperatures, the values of which, both absolute and relative, sha
49、ll remain within limits. Finally, on completion of the test, the bearings and the grease will be inspected and shall not show any changes beyond limits imposed. 6.2 Execution 6.2.1 Test rig The test rig shall apply testing conditions which are derived from the service operating conditions and ensure accurate monitoring of the axleboxes under test and at the same time minimize influence from the rig. Especially, it shall be avoided that disturbances on one axlebox are transferred to the o
