Foreword

GB /Z18620 "Cylindrical Gear Inspection Code of Practice" includes the following four parts. --- Part 1. Inspection of the 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. This part is the fourth part of GB /Z18620. This section identical with ISO /T R10064-4..1998 "Cylindrical Gear Inspection Practices Part 4. Surface Structure and Gear Teeth Speckle Test Specified Documents "(in English). This section is equivalent translation ISO /T R10064-4..1998. For ease of use, this section made the following editorial changes. --- According to the Chinese habit of some layout format has been modified; --- With the decimal point "." Instead of as a decimal point ","; --- ISO /T R10064-4..1998 reference to other international standards, have been adopted as our standard, with our standard Instead of the corresponding international standards, has not been adopted as the equivalent of China's direct reference to international standards. This section is the GB /Z18620.4-2002 "Cylindrical gear inspection specification Part 4. Surface structure and gear contact spot Point of inspection "of the amendment. Compared with GB /Z18620.4-2002, the main content is revised as follows. --- Some of the terms of the text has been modified. Appendix A of this section is informative appendix. This part is proposed by China Machinery Industry Federation. This part of the National Standardization Technical Committee gear centralized. This section is drafted. Zhengzhou Machinery Research Institute, Mechanical Science Research Institute. The main drafters of this section. Zhang Yuanguo, Ming Chuihsin, Zhang Minan, the beginning of loyalty, Wang Changlu, Wang Qi, Yang Xingyuan, Chen Aimin, Lin Taijun, Xu Hongji. This part of the standard replaces the previous editions are. --- GB /Z18620.4-2002. 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 CONTACT

1 Scope

This 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.
