Foreword

This standard is GB/T 7549-1987 "Cage Synchronizing universal coupling type, basic parameters and the main dimensions," the amendment. This standard and GB/T 7549-1987 have compared the contents of the following changes. --- According to GB/T 1.1-2000 preparation of this standard; --- Modify the standard name, the original standard name "Cage Synchronizing universal coupling type, basic parameters and the main dimensions" to "ball Synchronizing universal coupling cage "; --- Increasing the standard introduction, scope and normative references; --- The coupling model "QWL" to "WQL"; --- Increased WQF type and WQM type coupling, expanding the nominal torque range from the original "180N · m ~ 10000N · m" Expanded to "180N · m ~ 560000N · m"; --- Increased WQF WQM type and type markup example; --- Increase the technical requirements, inspection rules, marking, packaging, storage and so on. Appendix A of this standard is an informative annex. This standard by the National Standardization Technical Committee axis machines and accessories and focal points. This standard was drafted.
