Introduction

This specification is for the cylindrical straight teeth involute spline gauge calibration to develop the measurement technical specifications. Cylindrical straight teeth involute The spline gauge is a special gauge for controlling the involute spline tooth thickness (or alveolar width) of the workpiece. The main reference standard of this specification is GB/T 5106-2012 "cylindrical straight involute spline gauge"; GB/T 3478.5-2008 "cylindrical straight teeth involute spline (metric series of teeth with the side)"; GB/T 15758- 2008 "Spline Basic Terminology". Among them, the specification of the tooth thickness, the definition of tooth width and GB/T 15758 consistent, across the bar, bar spacing Test. --- The metering characteristic symbol is the same as the symbol of GB/T 5106, but the symbol of tolerance in GB/T 5106, In this specification is expressed as an error symbol. --- APPENDIX A Cylindrical Straight Straightening Spline Spline gauge is consistent with GB/T 5106. --- Appendix B Spline gauge size tolerance consistent with GB/T 5106, single tolerance compared with GB/T 5106 Increased wear limit. - The calculation example of the three-pin (or ball) in Appendix C is consistent with GB/T 5106. --- The contents of Appendix E are consistent with GB/T 3478.5. This specification is the first release. Standard Specification for Cylindrical Straight Straight Thread Spline Calibration
