Foreword
This standard is revised on the basis of JB4316-86 "Parameters and Dimensions of Spur End Chain Disc Series". This standard is consistent with the technical content of JB4316--86, and has only been re-edited in accordance with relevant regulations. This standard is part of the JB/T4316 "Spur End Chain" series of standards. This series of standards includes the following two parts: JB/T4316.1-1999 Parameters and dimensions of spur-end chainring series JB/T4316.2-1999 Accuracy inspection of spur-end chainring This standard replaces JB4316-86 from the date of implementation . Appendix A and Appendix B of this standard are both reminder appendices. This standard was proposed by the National Metal Cutting Machine Tool Standardization Technical Committee. This standard is under the jurisdiction of the Combination Machine Tool Branch of the National Metal Cutting Machine Tool Standardization Technical Committee. The units responsible for drafting this standard: Dalian Combined Machine Tool Research Institute, Yuxi Machine Tool Factory, Shenyang Second Machine Tool Factory. This standard was first published in 1986.

Spur end gear
Series parameters and dimensions
This standard only specifies straight end gears The series parameters and interchangeable dimensions of the disc (referred to as the toothed disc). This standard applies to gear discs used for circular indexing of metal cutting machine tools. 2 Main parameters
2.1 Outer diameter series
Taking the outer diameter of the toothed disc as the main parameter, the outer diameter series of the toothed disc is as follows: JB/T4316.11999
replaces JB 4316-86 | |tt | 2.2 Tooth number series
The tooth number series of the tooth plate is as follows:
60;72;120;144;180;240:360 and 7203 size
tooth plate with an outer diameter of 100-1600mm, Its interchangeable dimensions should comply with the requirements in Figure 1 and Table 1. Starting screw inspection hole
Main 0
Note: In the toothed disc pair, the center of the starting screw hole of the toothed disc 1 should be with the symmetrical center line of the teeth Coinciding with each other, the symmetrical middle set of the teeth of the other tooth plate 1 and the tooth grid
