Results of ISO/TS 6336-22 Evaluating Full Contact ZoneISO/TS 6336-22 (Calculation of load capacity of spur and helical gears—Part 22: Calculation of micropitting load capacity) is the ISO technical specification containing a proposal for a calculation of risk of micropitting in gear sets. ISO/TS 6336-22 calculates a safety factor against micropitting by comparing the minimum specific lubricant film thickness to the permissible lubricant film thickness. Unfortunately, ISO/TS 6336-22 does not recommend a minimum safety factor. Rather, it is left to the engineer to compare the calculated results to a similar gear application.Test Rig for Crowned Spline Joints with Optimized Surface Treatments Under Misaligned ConditionsFactors influencing the load-carrying capacity of crowned spline joints include the material and heat treatment, the manufacturing history and single manufacturing steps, the final surface properties as well as the prevailing boundary conditions during operation, such as lubrication and temperature. Further investigations on the influencing variables on the spline-joint load capacity such as different materials, heat treatments, surface conditions and optimizations, lubrications, test temperatures, or microgeometries can be performed. | ||
