The work of preparing International Standards is normally carried o
15、ut through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO c
16、ollaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approva
17、l by at least75% of the member bodies casting a vote. International Standard ISO4510-2 was prepared by Technical Committee ISO/TC127, Earth-moving machinery, Subcommittee SC3, Operation and maintenance. This second edition cancels and replaces the first edition (ISO4510-2:1986), which has been techn
18、ically revised. ISO 4510 consists of the following parts, under the general title Earth-moving machinery Service tools: Part 1: Common maintenance and adjustment tools; Part 2: Mechanical pullers and pushers. Annex A of this part of ISO 4510 is for information only. Descriptors: Earth-moving equipme
19、nt, maintenance, repairs, tools, hand tools, assembly tools, specifications, dimensions.BS6913-15:1997 BSI 09-1999 1 1 Scope This part of ISO 4510 specifies for guidance the types, general requirements and main nominal dimensions of mechanical pullers, attachments and adaptors used for carrying out
20、repair work. This part of ISO 4510 includes mechanical pullers and push pullers, pulling attachments and adaptors which are commonly used for pulling gears and bearings mounted on the types of earth-moving machinery defined in ISO6165. Machine manufacturers should consider the usage of these pullers
21、 and pushers for carrying out repair work (see for example notes in Figure A.1,Figure A.4 andFigure A.5); choosing dimensions for machine design fromTable 1 toTable 4, and specifying, in suitable manuals as described in ISO6750, the type of tools to be used for carrying out repair work. 2 Normative
22、references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO4510. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO4510 ar
23、e encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

(Revision of ISO 6165:1987)BS6913-15:1997 2 BSI 09-1999 3.2 Push pullers Figure 2 shows a push puller. Push pullers can be used alone (seeFigure A.4) or in combina
26、tion with internal pulling attachments (seeFigure A.5) or external pulling attachments (seeFigure A.6) for removal and installation of gears, bearings, shafts and other press-fitted parts.

27、a) can be used alone (seeFigure A.3) or in combination with push pullers (seeFigure A.5) for removal of bearing cups, oil seals, bushes and other parts from blind holes without damage. External pulling attachments seeFigure 3b) are used in combination with pullers (seeFigure A.2) or push pullers (se
28、eFigure A.6) to remove the bearing outer race and other parts where space does not permit the jaws to fit directly behind the parts to be removed. 3.4 Pulling adaptor, male and female thread Pulling adaptors (seeFigure 4 andFigure 2) are used at the ends of the legs of push pullers. 3.5 Step plate a
29、daptor Step plate adaptors (seeFigure 5) are used to protect shaft centres from distortion when extreme pressure is applied through the puller screw. These adaptors are also used between the end of the puller screw and the hollow shaft (seeFigure A.2,Figure A.4 andFigure A.6). Figure 3 Figure 4 BS69
30、13-15:1997 4 BSI 09-1999 4 General requirements 4.1 Pullers and attachments shall be designed to allow free movement and minimum clearance between the parts. 4.2 The head of the forcing screw and/or its nuts, which are tightened during repair work, shall be either square or hexagonal in shape and of
31、 a size suitable for accepting a standard size wrench, as specified in ISO4510-1. 4.3 The pressure end of the forcing screw shall have a60 conical point to ensure that loads are applied in the shaft centre. 4.4 The gripping ends of the jaws shall be used to prevent slippage from the gear or bearing
32、being pulled, at any setting within the capacity of the pullers. 4.5 Internal and external pulling attachments shall be suitable for use with push pullers and pullers, respectively, when required. 4.6 Pulling adaptors shall be used with push pullers, where applicable. 4.7 Step plate adaptors shall b
33、e used with pullers and push pullers on shaft ends with internal hole or without centre hole. 5 Dimensions The illustrations inFigure 6,Figure 7 andFigure 8 are for the convenience of identification and are not intended to specify the structure (shape, configuration, etc.) of pullers and associated
34、attachments. NOTEInch dimensions are not specified in this part of ISO4510. Inch dimensions equivalent to the metric dimensions given may only be used when there is a need to reflect local conditions. 5.1 Jaw tips of pullers The dimensions of the jaw tips of pullers are given inFigure 6 and Table 1.
