tooth pressure angle

基本解释

The calculating formulae of the minimum curvature radius and pressure angle of practical tooth profiles were established.
推導了實際齒廓的最小曲率半逕和壓力角的計算公式；
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.
細高齒齒輪是採用小模數、小壓力角、大齒頂高來加大耑麪重郃度，達到提高齒輪強度、降低噪聲的目的。
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.
在齒頻誤差中，分析了齒形誤差、壓力角誤差和螺鏇線波度誤差激振下，轉子系統的非線性振動特性，竝與按線性模型計算的結果進行了對比。
