GB /Z18620.4-2008/ISO /TR10064-4..1998 ISO Foreword ISO (International Organization for Standardization) is a worldwide federation of standardization bodies (ISO member groups) in various countries, which set international standards Quasi-standard work is usually done by the Technical Committee of ISO , and each member body interested in a standard project already established by a Technical Committee The right to participate in the work of the Committee, the international organizations (official or non-official) liaising with the ISO can also participate in the work. in Standardization of electrical technology, ISO and the International Electrotechnical Commission (IEC ) to maintain close relations of cooperation. The main task of a technical committee is to establish international standards, but in exceptional cases the technical committee may suggest the following types of A Technical Report (TR). --- Type 1 After repeated efforts have not yet received the support needed to release an international standard; --- The second type When the project is still in technological development, or for various reasons, only in the future rather than the current possible Agree to become an international standard --- Type 3 The types of information collected by technical committees differ from the international standards that are normally released (for example, process conditions). Type 1 and Type 2 technical reports should be reviewed within three years of release to determine whether they can be converted into international standards The third type of technical report does not have to be reviewed and has been used until the information provided is no longer considered to be valid or valid. ISO /T R10064-4 is the third type of technical report, which was developed by the ISO /T C60 Gears Technical Committee. ISO 10064 includes the following sections under the general title "Cylindrical Gear Inspection Practices". --- Part 1. Test of gear teeth on the same side; --- Part 2. radial integrated deviation, radial runout, tooth thickness and backlash test; --- Part 3. Gear billet, axis center distance and axis parallelism test; --- Part 4. surface structure and gear tooth contact test. GB /Z18620.4-2008/ISO /TR10064-4..1998 ISO Introduction In revising ISO 1328. 1975, it was decided that the description and values of surface texture and gear tooth contact speckles should be used as a 3 types of technical reports, volume release. A series of documents listed in Chapter 2 (Normative references), together with this technical report, have been Formulated to replace ISO 1328. 1975. GB /Z18620.4-2008/ISO /TR10064-4..1998 Cylindrical Gear Inspection Code of Practice PART 4. SURFACE STRUCTURE AND TESTING OF TOOTH CONTACT1 ScopeThis section provides recommendations on gear tooth surface roughness and gear tooth contact spot detection methods. The numerical values provided in this section should not be used as a strict precision criterion, but as a common agreement on steel or iron gear guide to use.2 Normative referencesThe provisions of the following documents through the GB /Z18620 of this part of the reference and become the provisions of this section. For dated references, All subsequent amendments (not including errata content) or revisions do not apply to this section, however, to encourage the agreement reached under this section The parties study whether the latest versions of these documents are available. For undated references, the latest version applies to this section.
