摘要
文章对与减小磨损相关的齿轮端面网纹加工工艺进行研究,利用MATLAB软件模拟磨削网纹,砂轮半径、工件转速、砂轮转速一定,磨削时间越短,网纹越明显,粗糙度值越大。磨削时间、砂轮半径一定,不同的工件转速和砂轮转速磨削加工后的结果与仿真结果基本一致,图形显示网纹越密集,实际加工工件的粗糙度值就越小。同时,工件端面加工出网纹能够消除工件端面早期快速磨损,提高耐磨性。端面网纹形成储油空间,减少磨损,延长工件的使用寿命。
The processing technology of meshes in gear end surface which relates to reducing abrasion was studied.Using MATLAB software to simulate the meshes, when the radius of the grinding wheel, rotation speeds of workpiece and the grinding wheel are constant, the shorter the grinding time, the more obvious the meshes, the higher the roughness value; when the grinding time and the radius of the grinding wheel are constant, the results after grinding process with different rotation speeds of workpiece and the grinding wheel are basically consistent with the simulated results. The results show that the denser the meshes is, the smaller the roughness value of the workpiece is in actual processing. The meshes which is processed in the end surface of the workpiece, can eliminate rapid abrasion of the end surface of the workpiece in the early time, thus improving abrasive resistance. Moreover, the meshes in the end surface of the gear can provide oil storage space, and reduce surface abrasion, thus prolonging the service life of the workpiece.
