    21、ernational Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee ha

    22、s 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 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical

    23、standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75% of the member bodies casting a vote. International Standard ISO8826-2 was prepared by Technica

    24、l Committee ISO/TC10, Technical drawings, product definition and related documentation. ISO 8826 consists of the following parts, under the general title Technical drawings Rolling bearings: Part 1: General simplified representation; Part 2: Detailed simplified representation. Annex A of this part o

    25、f ISO 8826 is for information only. Descriptors: Drawings, technical drawings, bearings, rolling bearings, graphic methods.ENISO8826-2:1997 BSI 05-1999 1 Introduction ISO8826 provides rules for the simplified representation of rolling bearings. The principle of drawing practice is to depict the obje

    26、ct to scale using lines. In simplified representations, only essential features are shown, preferably in outline (in order to save time and effort). The degree of simplification depends on the kind of object represented, the scale of the drawing and the purpose of the documentation. This means that

    27、either a general simplified representation or a detailed one may be used. A detailed representation shows more details of rolling bearings, for example the number of rows or the possibility of alignment. In order to avoid misunderstandings, only one kind of simplification, either the general or the

    28、detailed simplified representation, should be used on a drawing. 1 Scope This part of ISO 8826 specifies a detailed simplified representation for various rolling bearings. This representation should be used in cases where it is not necessary to show the exact shape and details of the rolling bearing

    29、s, for example in assembly drawings. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO8826. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parti

    30、es to agreements based on this part of ISO8826 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

(Revision of ISO 582:1979) Figure 1 ENISO8826-2:1997 2 BSI 05-1999 Examples of combinations of bearing features (according toTable 1) and load-bearing characteristics are given inTable 2. In representations perpendicular to the bearing axis, the rolling element may be shown

    37、 as a circle, regardless of its actual shape (ball, roller, needle,etc.) and size (seeFigure 1). 3.3 Detailed simplified representation The detailed simplified representation of rolling bearings is shown in Table 3 to Table 6. Roller bearings shown in Table 3 to Table 5 are always depicted in the sp

    38、ace above the horizontal axis of the bearing, while Table 6 refers to the vertical axis of the bearing.
