大模数、大直径齿轮的加工,一直存在着加工精度低、使用寿命低、噪声大、承载能力小等问题。目前,已有部分工厂采用了硬齿面或中硬齿面的滚刮加工工艺,但其齿面粗糙度较差。为此,我厂对大型齿轮的珩磨工艺进行了研究和试验,取得了较好的效果。下面介绍的是一种为解决大型珩齿设备的缺乏,而在立车上进行珩齿的工艺方法,供读者参考。一、珩齿原理珩齿工作原理是相当于一对紧密啮合的螺旋齿轮在自由对滚展成加工。珩轮是用环氧树脂和磨料等物浇注成型的刀具。珩齿过程中。在珩削速度和珩削压力的作用下,珩去被珩齿轮齿面上的微薄金属层,逐渐达到所要求的珩削尺寸和几何精度以及较好的齿面 Large modulus, large diameter gear processing, there has been the processing of low precision, low life, noise, load carrying capacity and other issues. At present, some factories have adopted the rolling process of hardened or hardened surfaces, but their surface roughness is poor. To this end, I plant on a large gear honing process were studied and tested, and achieved good results. Described below is a solution to the lack of large-scale honing equipment, and in the vertical car honing technology for readers reference. First, the honing principle Honing work principle is equivalent to a pair of closely meshing helical gears in the free to roll into processing. Honing wheel is made of epoxy resin and abrasive casting molding tool. Honing process. Honing the speed and honing pressure under the effect of honing the hinging gear to be a thin metal layer on the tooth surface, and gradually achieve the required honing size and geometric accuracy and better tooth surface
