tooth pressure angle

基本解释

The calculating formulae of the minimum curvature radius and pressure angle of practical tooth profiles were established.
推导了实际齿廓的最小曲率半径和压力角的计算公式；
High tooth gear has small module, small pressure angle, and large addendum to enlarge the transverse contact ratio, improve gear strength, and reduce the noise.
细高齿齿轮是采用小模数、小压力角、大齿顶高来加大端面重合度，达到提高齿轮强度、降低噪声的目的。
Of all the gear frequency errors, the non-linear dynamic characteristics of gear tooth error, pressure angle error and sprial fluctuation error are compared with the results of the linear system.
在齿频误差中，分析了齿形误差、压力角误差和螺旋线波度误差激振下，转子系统的非线性振动特性，并与按线性模型计算的结果进行了对比。
