involute的翻译

In addition, the tooth profile of spiral bevel gear is spherical involute and the tooth surface is irregular space curved face which make it difficult to establish the accurate 3D models. The simulation analysis of meshing and optimization design of spiral bevel gears is greatly hindered.

同时弧齿锥齿轮齿廓形状为复杂的球面渐开线，齿面也为不规则的空间曲面，三维几何精确建模较为困难，导致其啮合仿真分析以及局部优化设计的相关研究工作难以开展和深入。

By considering the compressibility of lubricant and the transient effect of variable load, sliding Velocities and curvature varying with time and coordinate, the transient elasto-hydrodynamic lubrication analysis on spur involute gears is given.

本文综合考虑润滑流体的可压缩性、齿轮传动重合度对轮齿载荷的影响以及滑动速度、曲率半径随时间和座标变化的瞬态效应，对渐开线直齿圆柱齿轮传动进行瞬态弹流完全数值分析；

Grinding gear with involute enveloping hourglass interior screw thread worm grind wheel is a new kind of craft which combines the high productivity with the good quality.
