摘要:

研究了准双曲面齿轮采用产形线切齿法加工时,小齿轮和大齿轮产形线的几何关系,建立产形线数学模型,提出以简单曲线代替复杂的理论产形线,从而简化机床运动的产形线代用方法。最后,以一对给定设计参数的准双曲面齿轮为例,在大轮产形线为直线的情况下,求解小轮左齿面和右齿面的理论产形线,并分别采用圆弧线和直线代用,分析代用误差对齿轮传动的影响及减小该影响的措施,表明采用代用产形线加工准双曲面齿轮的可行性。

Abstract:

The geometrical relationship,which was used to manufacture hypoid gears by generating-line method,between two generating lines of pinion and gear was studied,and the mathematical model of generating lines was established.In order to simplify the movement of machine tool,the method of substituting simple curves for complex theoretical generating lines was proposed.Finally,taking a pair of hypoid gears,which the designing parameters were given and the gear generating line was straight,for example,the theoretical generating lines of left side and right side of pinion were solved and were substituted respectively by a circular arc and a straight line.The impact of substituting error on the gear drive and the measures of reducing this impact were analyzed,and it showed the feasibility of cutting hypoid gears by the substituted generating lines.

Key words: mechanical manufacturing technology and equipment, generating-line method, modeling of generating lines, substituting of generating lines
