BS 5892, which cov
8、ers railway rolling stock material, is published in the following six parts: Part 1: Specification for axles; Part 2: Specification for wheel centres; Part 3: Specification for monobloc wheels; Part 4: Specification for tyres; Part 5: Specification for steel bars for tyre-retaining rings; Part 6: Sp
9、ecification for wheel-sets for traction and trailing stock.The format of BS 5892 has been revised, with the tolerancing requirements for components moved from Part 6 to the part relevant to the particular component. It has been possible to relax certain of the tolerances for the wheelset assembly. T
10、his part of BS 5892 is related to ISO 1005-7; however, it has not been possible to obtain full equivalence. It is also related to UIC 813.0.BS 5892-1 to BS 5892-4 have also been revised to ensure consistency with the requirements of this part.Product certification. Users of this British Standard are
11、 advised to consider the desirability of third party certification of product conformity with this British Standard based on testing and continuing surveillance, which may be coupled with assessment of a suppliers quality systems against the appropriate part of BS 5750.Enquiries as to the availabili
12、ty of third party certification schemes will be forwarded by BSI to the Association of Certification Bodies. If a third party certification scheme does not already exist, users should consider approaching an appropriate body from the list of Association members.A British Standard does not purport to
13、 include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.Compliance with a British Standard does not of itself confer immunity from legal obligations.Summary of pagesThis document comprises a front cover, an inside front cover, pag

Other components (e.g. brake discs, gear wheels
27、, etc.) shall be as specified on the relevant drawings.4.1.2 Interference between axle seats and boresFor wheelsets having a seat length (measured on the axle) of between 0.8 and 1.1 times the seat diameter, a hub having a radial thickness of 30 mm or more and a solid axle, the interference shall be

The interference between the axle seats and the bores shall be within the range 0.0010 mm to 0.0013 mm per mill
29、imetre of wheelseat diameter.For wheelsets having different characteristics, the purchaser shall agree with the manufacturer the interference to be used.4.1.3 Lead-in taperAny lead-in taper for both shrink fitting and press fitting shall be on the axle seat, and not on the bore. The dimensions shall
30、 not exceed 0.4 mm measured on the diameter, and 10 mm measured along the seat.4.2 Wheelsets4.2.1 Mechanical characteristicsFor shrink or other non-press fitted wheels and wheel centres only, there shall be no displacement relative to the axle after application of the proving thrust test (see 9.1).T

37、2.1 Shrink fittingNOTE In order to obtain the full advantages of shrink fitting, it is essential that oil injection grooves are provided.The monobloc wheels or wheel centres shall be heated to a uniform temperature, sufficient to ensure the necessary expansion of the bore to allow it to fit on the s
38、eat on the axle. In no instance shall the temperature exceed 250 C.After removal from the heating area, the bore (or wheel centre) shall be wiped clean with a non-fluffing cloth to remove all oil, grease or other foreign matter. The axle wheelseat shall be clean and free from oil and grease. The whe
39、el (or wheel centre) shall be fitted to the axle in its final position, then allowed to cool in still air until the wheel grips the axle.5.2.2 Press fitting5.2.2.1 At the time of assembly, the monobloc The bore of the wheel, or wheel centre, and the corresponding axle seat shall be coated with a fil
40、m of rape oil, or any other lubricant if specified by the purchaser at the time of enquiry or order see item j) of clause 3.5.2.2.2 The wheel, wheel centre or wheel centre with tyre fitted shall be pressed onto its seat gradually by a hydraulic press, avoiding deformation of the wheelset components
41、and damage to any machined parts, particularly the journals.The press shall be equipped with a calibrated force indication device, permitting the recording of press force as a function of the position on the axle of the wheel being fitted. This recording shall be in indelible ink and to a scale suff
42、icient to allow evaluation of the press force at any point on the curve.Designation Symbol(see Figure 1)Service speed (V) Toleranceskm/h mmDistance between the inside faces of the two wheelsA1AllA2Difference between measured values of back face of flanges to abutment faces(C C1)or(C1 C)All 1.0Total

47、start to increase before the axle wheelseat is entered into the bore of the wheel or wheel centre by 20 mm.The press force diagram shall show the press force increasing gradually and smoothly with displacement of the wheel or wheel centre, until the maximum value, which shall not exceed that specifi
48、ed (Pf max), is attained.NOTE The reduction of press force due to the possible presence of oil injection grooves is permissible.This maximum value, as the pressing-on continues, shall not reduce by more than 50 kN, and this shall not reduce the force to below the minimum specified (Pf min), nor shal
49、l it occur prior to the last 25 mm of displacement.NOTE Figure 2 illustrates this procedure.5.2.3 Other methods of assemblyOther methods of assembly shall be as agreed between the purchaser and the manufacturer see item j) of Clause 3. The manufacturer shall demonstrate that any novel fitting method does not adversely affect the integrity of the wheelset assembly.
