| 摘 要： | 齿轮传动由于受制造和安装误差、齿轮弹性和热变形等因素的影响,在啮合过程中不可避免地会产生振动、冲击和偏载,从而造成齿轮效率和寿命偏低的问题。针对该问题,运用虚拟仿真验证手段,以典型外啮合直齿圆柱齿轮为研究对象开展螺旋线修形优化。结果显示,优化后齿轮表面应力分布均载程度提高78.31%,传动误差降低41%,螺旋线载荷分布系数降幅达到39.3%,接近于1。可见,螺旋线修形能够显著改善因各种因素综合引起的螺旋线偏差,改善传动状态,提高啮合质量。

| Abstract: | In view of the inevitable vibration, impingement and deflection during the meshing process due to manufacturing and installation errors, gear elasticity and thermal deformation, resulting in low gear efficiency and life, the helix shaping optimization is carried out with a typical external meshing straight cylindrical gear by using virtual simulation verification. The results show that the optimized gear surface stress distribution is 78.31% more evenly loaded, the transmission error is 41% lower, and the helix load distribution coefficient is 39.3% lower, which is close to 1. It can be seen that helix shaping can significantly improve the helix deviation caused by a combination of various factors, improve the transmission state and improve the meshing quality. |
