摘　　要：为了提升渐开线斜齿圆柱齿轮在实际工况下的齿面承载能力,对不同误差影响下产生啮合错位的齿轮副进行分析和优化。在考虑整个系统刚度影响的情况下,利用软件多次迭代计算得出齿轮副的系统啮合错位量,再引入受精度和公差等随机因素影响的随机啮合错位量,准确分析错位源和贡献程度,以此为依据计算判断齿轮微观修形的方式和修形量。分析了4种算例,分别为有系统错位,无随机错位和修形的齿轮传动;有系统错位和针对系统错位的修形,无随机错位的齿轮副;2种错位都有但无修形的齿轮副;2种错位都有且加以考虑了2种错位的修形的齿轮副。最后,对这4种算例的齿轮副作啮合质量的对比分析,验证修形对错位影响的补偿效果。In order to improve the tooth surface bearing capacity of involute helical cylindrical gear under actual working conditions,the gear pairs with meshing dislocation under the influence of different errors were analyzed and optimized.Under the condition of considering the effects of the whole system stiffness,the system meshing displacement of gear pairs was calculated using software multiple iterations,then the random mesh displacement quantity by the influence of random factors,such as precision and tolerance,was introduced,the dislocation source and the degree of contribution were accurately analyzed,and based on this,the judging method and the amount of micro gear modification were calculated.Four kinds of examples were analyzed,which were,the gear transmission with systematic dislocation,no random dislocation and shape modification;gear pair with system dislocation and modification for system dislocation,without random dislocation;gear pair with both kinds of dislocation but without modification;gear pair with both kinds of dislocations and the modification of both kinds of dislocations were considered.Finally,the meshing quality of the gear pairs in these four examples was compared and analyzed to verify the compensation effect of modification on dislocation.
