摘要
剃齿加工作为齿轮精加工的方法之一,因其效率高、成本低而被广泛的应用于齿轮制造领域。由于使用标准渐开线齿形剃齿刀进行剃齿,在工件齿形节点附近会出现不同程度的"中凹"现象。这种齿形不仅影响齿轮的传动精度,而且会增大传动噪声,缩短齿轮的使用寿命。以ADAMS软件为分析工具,对剃齿刀-齿轮的无侧隙啮合加工过程进行了接触仿真分析,得出了沿齿廓曲线上的接触压力分布结果。并在ADAMS环境的Post/Process模块下,以趋近满足整个齿廓曲线等接触压力为目标,对剃齿刀-齿轮啮合的最大接触压力进行了基于仿真分析优化,从而进行了齿廓修形。
Gear shaving machining is the one way of gear finish machining;this machning processing is applied in the gear manufacturing widely because of its high efficiency and low cost.Due to the use of standard involutes gear shaving cutter for shaving,the work piece profile nodes occur with varying degrees of 'concave' phenomenon.This profile not only affects the gear transmission accuracy,but also can increase the transmission noise,shorten the service life of the gear.By using ADAMS software analysis tool,the non-backlash meshing process of the shaving cutter gear was done with contact simulation analysis,reaching results of the tooth profile curve of the contact pressure distribution.And in the ADAMS environment Post/Process module,in order to meet the needs of the whole tooth profile curve approach contact pressure,the shaving cutter gear meshing of the maximum contact pressure was carried out based on the experimental design optimization,which conducted the tooth profile modification.
