During attrition process, closed in the working face of the first abrasive disk straight-line groove and the first abrasive disk helicla flute working face In each attrition process region H made of enclosing, be processed taper roller rolling surface respectively with the first abrasive disk straight-line groove Working face two sides and the second abrasive disk helicla flute working face one occur line contact, be processed taper roller stub end Ball basal plane or stub end rounded corner or small head end rounded corner occur line with the working face two of the second abrasive disk helicla flute and contact, the It is processed taper roller under the friction-driven of the working face of two abrasive disk helicla flutes to rotate around own axes, is processed taper roller Opposite sliding occurs for the working face of rolling surface and the first abrasive disk straight-line groove, is rolled to realize to being processed taper roller The attrition process on surface.The direct phase of contact stress of the material removal and rolling surface and straight-line groove working face of rolling surface It closes, when the high point and straight-line groove of larger-diameter processed taper roller rolling surface or processed taper roller rolling surface When working face contacts, the contact stress of rolling surface and straight-line groove working face is larger, and the material of the rolling surface of contact position is gone It is larger except measuring；When the processed taper roller rolling surface of small diameter or the low spot of processed taper roller rolling surface and directly When line trenches working face contacts, the contact stress of rolling surface and straight-line groove working face is smaller, the rolling surface of contact position Material removal amount is smaller.To can realize taper roller rolling surface high point material more remove, low spot material remove less, diameter compared with The material of big taper roller rolling surface removes more, the material of the smaller taper roller rolling surface of diameter removes less.
Due to the opening Design of the first abrasive disk straight-line groove and the second abrasive disk helicla flute, there are quilts in attrition process Taper roller is processed between the first abrasive disk and the second abrasive disk along the straight-line feed of straight-line groove baseline and via billowing son It is processed taper roller when recycling disk external system to collect, conveying, arrange, the cycle of feeding, and disk external system is recycled via roller Original order can be disturbed.
On the one hand, the opening Design of the first abrasive disk straight-line groove and the second abrasive disk helicla flute is adapted to large quantities of very much Measure the finishing of taper roller rolling surface；On the other hand, the processed taper roller upset when recycling disk external system via roller Order so that " taper roller rolling surface high point material removes preceding feature more, low spot material removes less, the circular cone being relatively large in diameter The material on roller rolls surface removes more, the material of the smaller taper roller rolling surface of diameter removes less " can diffuse to it is whole A processing batch, to can be improved entire batch taper roller rolling surface form accuracy and dimensional uniformity；Another side When face is due to attrition process, the first abrasive disk straight-line groove and the second abrasive disk helicla flute have dozens of to as many as hundreds of friendships It can locate, i.e., there are dozens of to hundreds of processed taper rollers to participate in grinding simultaneously, so as to improve taper roller rolling table The processing efficiency in face reduces processing cost.
Moreover, because the setting of the second abrasive disk internal magnetization structure, in the processed taper roller of ferromagnetism material The magnetic of the working face of the second abrasive disk helicla flute to the processed taper roller of ferromagnetism material is introduced in dynamic balance system Power, and be applied to by the opposite approach of the first abrasive disk and the second abrasive disk when the magnetic attraction is independently of attrition process ferromagnetic The operating pressure of the processed taper roller of property material so that " working face of the second abrasive disk helicla flute is to described ferromagnetic for condition Property material processed taper roller around own axes rotate caused by sliding friction driving moment to be more than the first abrasive disk straight The working face of line trenches rotates generated sliding friction to the processed taper roller of the ferromagnetism material around own axes The moment of resistance " is easier to realize.
