GB/T 5106-2012 Straight cylindrical involute splines - Gauge
1 Scope
This standard specifies the terms and definitions, symbols and descriptions, classification, types and dimension parameters, tolerances, requirements, inspection methods, marking and packaging of gauges for straight cylindrical involute splines (hereinafter referred to as "gauges").
The gauges specified in this standard are applicable to the inspection of splines with the pitch diameter less than or equal to 180 mm specified in GB/T 3478. This standard may be used for reference for the splines with the pitch diameter greater than 180 mm or those not specified in GB/T 3478.
