In addition, the CAD system includes some more utility modules, such as module of gear calculation of error of gear profile, module of gear measurement, module of looking up nation standard of gear.

另外，在齿轮CAD系统中还设计了齿廓误差计算、齿轮测绘及齿轮国家标准查询等一些具有较大实用价值的模块。

According to the new national gear standard, three deviation-measuring items must be included in the checkout of single gear: profile deviation, helix deviation and pitch deviation.

按照新的国家齿轮标准规定，对于单个齿轮必须检验三个偏差项目：齿廓偏差、螺旋线偏差和齿距偏差。

The results are compared to those of the standard involute gear and proof that the bending strength of the composite profile tooth is higher than that of involute one.

结果表明，复合齿形齿轮比渐开线齿形齿轮具有更高的弯曲强度。
