10、BS ISO 199:2014ISO 199:2014(E)ForewordISO (the International 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 interest

11、ed 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 collaborates closely with the International Electrotechnical Co

12、mmission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents

13、 should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible fo

14、r identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the c

17、ISO 2014 All rights reservedBS ISO 199:2014ISO 199:2014(E)IntroductionThis International Standard is a machine element geometry standard as defined in the geometrical product specification (GPS) system as presented in master plan of ISO/TR 14638.10The fundamental rules of ISO/GPS given in ISO 80157a

18、pply to this International Standard and the default decision rules given in ISO 14253-18apply to the specifications made in accordance with this International Standard, unless otherwise indicated.The connection between functional requirements, measuring technique and measuring uncertainty is always

19、intended to be considered. The traditionally used measuring technique is described in ISO 1132-2.5For measurement uncertainty it is intended that ISO 14253-29should be considered.

20、cation (GPS) and tolerance values1 ScopeThis International Standard specifies dimensional characteristics, limit deviations from nominal values, and tolerance values to define the interface (except chamfers) of thrust rolling bearings. Nominal boundary dimensions are defined in ISO 1041.This Interna

21、tional Standard is not applicable to certain thrust bearings (e.g. thrust needle roller bearings) or for particular fields of application (e.g. special thrust precision bearings). Tolerances for such bearings are given in the relevant International Standards.Chamfer dimension limits are given in ISO

22、 5823.2 Normative referencesThe following documents in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any a

23、mendments) applies.ISO 5593, Rolling bearings VocabularyISO 14405-1, Geometrical product specifications (GPS) Dimensional tolerancing Part 1: Linear sizesISO/TS 17863, Geometrical product specification (GPS) Geometrical tolerancing of moveable assemblies3 Terms and definitionsFor the purposes of thi

24、s document, the terms and definitions in ISO 5593, ISO 14405-1, and ISO/TS 17863 apply.4 SymbolsTo express that the ISO/GPS system, ISO 8015 7is applied, the dimensional characteristics shall be included in the technical product documentation (for example on the drawing). The dimensional specificati

25、ons, associated to these characteristics, are described in Table 1 and Figures 1 to 4.Descriptions for symbols are in accordance with GPS terminology; relationships with traditional terms are described in Annex A.A tolerance value associated to a characteristic is symbolized by t followed by the sym

26、bol for characteristic, for example, tdmp.In this International Standard, the ISO default specification operator for size is in accordance with ISO 14405-1, i.e. the two-point size is valid. Some specification modifiers are described in Annex D.The detailed definitions for terms in ISO 14405-1 and t
