本文介绍了成形磨削圆柱斜齿轮时,砂轮磨损和修正所引起的直径减小量对齿形加工精度的影响,提出了采用定直径砂轮磨削的新方法,并在国内外开槽砂轮和爪式卡盘研究与实践的基础上,结合国内的现行生产条件设计和试制了两种组合式静态调整的定直径砂轮。经过对其静、动态特性的理论分析和与整体砂轮作比较的磨削性能试验证明,定直径砂轮除在刚度、强度、磨齿精度和表面质量等方面都可以达到与整体砂轮相同的性能外,还具有直径可精确补偿和比整体砂轮磨削率高、磨削热低等特点。因此可以认为,定直径砂轮的研制和应用将为提高斜齿轮成形磨削精度提供一个有效而经济的新方法,并为解决类似一些对砂轮直径变化有要求的高精度曲面磨削加工在工艺上开辟一个新的途径。
In this paper, the effect of reducing the diameter caused by the wear and the correction of the grinding wheel on the machining accuracy of the profile when the cylindrical grinding helical gear is formed is introduced. A new method of grinding with constant diameter grinding wheel is put forward. At the same time, Based on the research and practice of claw chuck, combined with the current domestic production conditions design and trial production of two combined static adjustment of the diameter wheel. After its static and dynamic characteristics of the theoretical analysis and compared with the overall grinding wheel grinding performance test shows that in addition to constant diameter grinding wheel in the stiffness, strength, grinding accuracy and surface quality can reach the same with the overall performance of the wheel , But also has a diameter that can be accurately compensated and grinding rate than the overall high rate of grinding heat low and so on. Therefore, it can be considered that the research and application of the constant diameter grinding wheel will provide an effective and economical new method to improve the grinding accuracy of the bevel gear forming. In order to solve the problem of high precision surface grinding which is similar to the requirement of the wheel diameter variation, Open up a new way.
