本文用有限单元法不仅较准确地计算出标准剃齿刀和迭片剃齿刀在剃齿过程中刀齿的位移值(即变形量),特别重要的是用此法可以计算出沿全齿高的变形分布情况。从计算得知两种刀齿在同样载荷(切削力)作用下,迭片剃齿刀的刀齿刚度较标准刀齿的大3～4倍;迭片刀齿的变形分布乃由齿顶到齿根逐渐平缓地减小,而标准位刀齿的变形幅度却很大。这些结论都为进一步完善迭片剃齿刀的设计和使用提供了理论依据。
In this paper, finite element method is not only more accurate calculation of the standard shaving cutter and lamination shaving cutter teeth in the tooth displacement value (ie, deformation), especially important is the use of this method can be calculated along the entire tooth High deformation distribution. From the calculation, it can be seen that under the same load (cutting force), the cutter tooth rigidity of the split shaving cutter is 3 to 4 times larger than that of the standard cutter tooth. The deformation distribution of the split cutter tooth is determined by the addendum to Dedendum gradually decreased gently, while the standard bit teeth deformation amplitude is very large. All these conclusions provide the theoretical basis for further improvement of the design and use of lancets.
