检测结果表明：齿轮激光淬火变形很小，不影响齿轮的精度等级。
Test results show that deformations in laser hardened gears was negligible to influence gear precision.
评级建立在强度计算上。基本的静态强度等级、或用手操作的设备以上齿轮的3倍，大约是100每分钟转速的评价。
Ratings are based on strength calculation. Basic static strength rating, or for hand operation of above gears, is approximately 3 times the 100 RPM rating.
