立方氮化硼砂轮磨削齿轮材料表面质量的研究

Research on the SPecificity of CBN wheel in Gear Grinding

本文着重研究了立方氮化硼砂轮和刚玉砂轮磨削２０Ｃｒ２Ｎｉ４、２０ＣｒＭｎＭｏ、２０ＣｒＮｉ２Ｍｏ、１７ＣｒＮｉＭｏ６及１５ＣｒＮｉ３Ｍｏ五种齿轮材料的磨削性能。利用立方氮化硼砂轮磨削齿轮，能够得到更优越的表面质量。

For studing the grinding specificityof cubic boron nitride (CBN) wheel and aluminum oxide (GB) wheel, five types of casehandening gear material. including20CrMnMo, 20Cr2Ni4, 20CrNi2Mo, 15CrNi3Mo and 17CrNiMo6 are tested.It is shownthat the grindinfi specificity of CBN wheelis quite superior to that of alllminum oxide wheel.Calculation and Design of Uneven Film Chuck forGrinding Gear Holes Chen Chuxuen, et al. (45)Abstract The construction and calculation of thechuck introduced in the paper has been improved basedon the thesis [1.j, the even plate of .the film chuck ischanged into uneven one. After improving, deformation and streess distribution of the film plate is morereasonable and the property is better, and the life islonger.
