BS EN 12082:2007+A1:2010EN 12082:2007+A1:2010 (E) 4 Introduction This European Standard has been drawn up with the purpose of standardizing the performance testing of axleboxes for all types of rolling stock to ensure suit
24、ability 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 made up of two stages, a “rig performance test“, described in detail in this European Standard, and a “field test”. When rig performance t
25、esting 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 design, seal design, grease formulation or box housing, as well as the application (see EN 12080 and EN 12081). The rig performance test wi
26、ll 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 suppliers that operate a quality management system1). The field test comprises monitoring on vehicles in service of a sufficiently large sample
27、of axleboxes during a high mileage. 1)The systems used should offer equivalence with EN ISO 9001. BS EN 12082:2007+A1:2010EN 12082:2007+A1:2010 (E) 5 1 Scope This European Standard specifies the principles and methods for a rig performance test of the system of box housing, rolling bearings, sealing
28、 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 performance requirements may be selected for vehicles in operation on other networks. Basic principles for a fiel
29、d test are also determined. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

The rig performance t
38、est 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 characteristics of the rolling bearing according to EN 12080; designation and charac
39、teristics 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 described in 6.2.2; extent of testing for rolling bearings for vehicles not i
40、n 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). BS EN 12082:2007+A1:2010EN 12082:2007+A1:2010 (E) 7 5 Watertightness test The customer shall specify wh
41、ether 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 test rig and subjecting them to repeated load
42、ing 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 test rig axle journals. After mounting, the cle
43、arance 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 forces on the rolling bearings. Calculating t
44、he constant nominal radial force nrF and the nominal axial load anF is carried out by means of the methods described in A.4. The constant radial load is designatedrF , and the varying actual axial load is designatedaF . All these forces are applied on one journal with axlebox. Other test parameters
45、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 performance test, a pre-test shall be carried out. This
46、 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 cycles up to an agreed cumulative distance. The nu
47、mber 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, shall remain within limits. Finally, on completion
48、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
49、 and at the same time minimize influence from the rig. Especially, it shall be avoided that disturbances on one axlebox are transferred to the other axlebox. An example of a test rig is schematically shown in A.1 and includes principally: a) axle or two synchronized axles, on which the axle boxes are mounted on the journals; b) rotation mechanism; c) device for measuring the rotational speed of the ax
