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 third part of GB /Z18620.

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
--- The third type of technical committee to collect different from the normal release of international standards of information (for example, to adapt to the current process
Level).
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 R10064-3 is the third type of technical report, which was developed by the ISO /T C60 Gears Technical Committee.
ISO 1328. 1975 In addition to including definitions and gear elements of the deviations and allowable values, but also provides the relevant test methods
opinion.
During the revision of ISO 1328. 1975, it was agreed that the descriptions and opinions of the gear inspection methods should be promoted to the modern
techinque level. Due to the increased content and other considerations, the Technical Committee decided to include the relevant paragraph as a Type 3 Technical Report,
Volume release. Also decided, in addition to this technical report, the normative references listed in Chapter 2 and Appendix B
Documents and a series of documents, should be used as guidance information.
ISO /T R10064, under the general title "Cylindrical gears inspection code of practice" includes the following sections.
--- 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.

Part 3. Gear billet, shaft center distance and
Axis parallelism test
1 Scope
This section provides the recommended values for gear blank, center-to-center dimensional deviation and axial parallelism.
The numerical values listed in this section should not be considered as strict quality guidelines, but rather on the steel or iron gear in the mutual agreement,
As a guide.
