Description

用于凸度滚子滚动表面精加工的研磨盘套件、设备及方法 技术领域
本发明涉及一种用于凸度滚子滚动表面精加工的研磨盘套件、研磨设备及研磨方法，属于轴承滚动体精密加工技术领域。
背景技术
滚子轴承(圆柱滚子轴承和圆锥滚子轴承)广泛应用于各类旋转机械。作为滚子轴承(圆柱滚子轴承和圆锥滚子轴承)重要零件之一的凸度滚子(凸度圆柱滚子和凸度圆锥滚子)，其滚动表面的形状精度和尺寸一致性对滚子轴承的性能具有重要影响。现阶段，公知的凸度滚子滚动表面的加工工艺流程为:毛坯成型(车削或冷镦或扎制)、粗加工(软磨滚动表面)、热处理、半精加工(硬磨滚动表面)和精加工。公知的凸度滚子滚动表面精加工的主要工艺方法是超精加工。
超精加工是一种利用细粒度油石作为磨具，油石对工件加工表面施加较低的压力并沿工件加工表面作高速微幅往复振动和低速进给运动，从而实现微量切削的光整加工方法。
目前，凸度圆柱滚子滚动表面的精加工多采用无心贯穿式超精加工方法。其设备的加工部分由一对异向斜置的超精导辊和一个(或一组)装有油石的超精头组成，凸度圆柱滚子由导辊支撑并驱动，在作旋转运动的同时又沿一与凸度圆柱滚子滚动表面素线相适应的轨迹作低速进给运动，在超精头以较低的压力将油石压向凸度圆柱滚子滚动表面的同时油石沿凸度圆柱滚子滚动表面的素线作高速微幅往复振动，对凸度圆柱滚子的滚动表面实施精加工。在无心贯穿式超精加工过程中，同一批次的凸度圆柱滚子依次贯穿通过加工区域并经受油石超精加工。
此外还有一种无心切入式超精加工方法，其设备的加工部分由一对平行布置的超精导辊和一个(或一组)装有油石的超精头组成，凸度圆柱滚子在导辊的支撑并驱动下作旋转运动，在超精头以较低的压力将油石压向凸度圆柱滚子滚动表面的同时油石沿一与凸度圆柱滚子滚动表面素线相适应的轨迹作低速进给运动和高速微幅往复振动，对凸度圆柱滚子的滚动表面实施精加工。在无心切入式超精加工过程中，同一批次的凸度圆柱滚子逐个进入加工区域并经受油石超精加工。
上述两种凸度圆柱滚子滚动表面超精加工方法存在以下两方面技术缺陷：一方面，加工过程中油石和导辊磨损状态随时间的变化不利于凸度圆柱滚子滚动表面形状精度和尺寸精度的提高；另一方面，由于超精加工设备同一时刻只对单个(或少数几个)凸度圆柱滚子进行加工，被加工凸度圆柱滚子滚动表面的材料去除量几乎不受同批次凸度圆柱滚子滚动表面直径差异的影响，因此用超精加工设备加工凸度圆柱滚子滚动表面很难有效改善被加工凸度圆柱滚子滚动表面的直径分散性。上述两方面的技术缺陷导致被加工凸度圆柱滚子滚动表面的形状精度和尺寸一致性提升受到制约。
现阶段，涉及凸度圆柱滚子滚动表面精加工的装置(设备)和方法还包括以下几种：
中国专利公报，公布号CN102476350A：公开了一种圆柱滚子外径无心研磨加工装置，包括两个半径一大一小的铸铁研磨辊，研磨辊之间有间隔，间隔上方安装有送料槽，送料槽上方设置有上压板，上压板上方加装有加压重锤，上压板与滚子的接触面为圆弧形。两 研磨辊的线速度不同，使得圆柱滚子与研磨辊之间产生相对滑动。调整小研磨辊在垂直和水平方向的角度可驱动滚子沿轴线方向进给。研磨辊在驱动圆柱滚子的同时，也对滚子表面进行研磨加工。
中国专利公报，公布号CN204736036U：公开了一种用于精密圆柱滚子外圆面研磨的加工装置。其特征在于：加工装置包括气缸、支撑架、磨具底板、磨具、驱动辊和底座，两个驱动辊与加工装置的对称中心平面平行，一个驱动辊的左边端在铅垂面内上翘与水平面相交成1～5°，另一个驱动辊的右边端在铅垂面内下翘与水平面相交成1～5°；两驱动辊表面涂覆有阻尼涂层以增大磨擦系数。磨具固定在磨具底板上，通过气缸施加加工压力，气缸安装在支撑架上，支撑架和驱动辊安装在底座上。加工时将圆柱滚子置于驱动辊一端，两个驱动辊产生的切向力使圆柱滚子绕中心轴旋转，产生的轴向力使圆柱滚子沿中心轴贯穿进给，磨具对滚子圆柱表面进行加工。
上述两种装置均采用两驱动辊支撑并驱动圆柱滚子前进，与圆柱滚子前进方向垂直的上方设有磨具对圆柱滚子圆柱表面进行加工，加工时所有圆柱滚子依次通过加工区域。此类装置具有与超精加工设备相同的两方面技术缺陷。
中国专利公报，公布号CN104608046A：公开了一种轴承圆柱滚子圆柱面超精密加工方法，其特征在于：采用双平面式圆柱零件外圆超精密加工设备对待加工圆柱滚子进行研磨；所采用的双平面式圆柱零件外圆超精密加工设备包括：上研磨盘、下研磨盘、外齿圈、偏心轮和保持架，其中上研磨盘、下研磨盘、外齿圈和偏心轮的转轴均同心放置，各自独立驱动；圆盘形保持架的盘面上开有多个工件夹持槽孔，槽孔呈放射状分布；保持架的旋转轴与偏心轮的中心同心设置，而保持架的中心与偏心轮的轴心存在偏距；保持架与外齿圈的齿轮配合，保持架由外齿圈和偏心轮同时驱动。研磨前将圆柱滚子置于保持架的槽孔中，对上研磨盘施加下压力；工件位于上研磨盘和下研磨盘之间，并与上、下研磨盘接触；驱动上研磨盘、下研磨盘、外齿圈和偏心轮旋转，工件在上、下研磨盘的驱动下作滚动运动的同时，也在保持架的驱动下绕上研磨盘和下研磨盘作摆线运动。
中国专利公报，公布号CN103522166A：公开了一种基于上盘偏心加压的圆柱形零件外圆加工方法，其特征在于：该加工方法的加工装置包括上研磨盘、保持架和下研磨盘。上研磨盘位于下研磨盘的上方，保持架位于上研磨盘与下研磨盘之间，保持架的转轴和下研磨盘的转轴呈同轴设置，上研磨盘的转轴与保持架的转轴存在确定偏距。加工时，加载装置通过上研磨盘偏心作用于圆柱形零件，通过上研磨盘和下研磨盘平面配合磨料对圆柱形零件外圆进行加工。
中国专利公报，公布号CN105798765A：公开了一种四平面往复式圆柱滚子研磨方法与装置，其特征在于：机架内设有由动力源带动转动的安装架，安装架周向外壁上设有若干用于安装圆柱滚子的安装槽；机架上与安装架对应设有与圆柱滚子滑动配合的研磨板。使用的时候将圆柱滚子安装在安装架上，通过转动安装架对研磨板中的多个圆柱滚子同时进行研磨。
上述的三种装置(设备)均可同时对多个圆柱形零件进行加工，直径较大的圆柱形零件圆柱表面材料去除量较大，有利于尺寸一致性的提高。但是，由于其加工装置(设备)的封闭特征，此类装置(设备)不具备大批量生产能力。
中国专利公报，公布号CN104493689A和CN104493684A：公开了一种圆柱形零件双 盘直槽研磨盘、研磨设备与研磨方法，所述设备包括工件推进装置、工件输送装置和研磨盘装置。所述研磨盘装置包括第一、第二研磨盘，两研磨盘相对转动，第一研磨盘的工作面为平面，第二研磨盘与第一研磨盘相对的表面上设有一组放射状的直沟槽，直沟槽的两侧面为第二研磨盘的工作面，第二研磨盘的工作面的横断面轮廓呈圆弧形或V字形或具有圆弧的V字形，所述待加工件与直沟槽的接触点或接触圆弧的中点处的法平面与所述直沟槽的基准面的夹角的取值范围为30～60°；所述直沟槽的近第二研磨盘的中心一端为推进口，所述直沟槽的另一端为出料口，所述工件推进装置设置在第二研磨盘中心通孔内，包括主体及其上安装的多个推料机构和储料槽。
利用该设备研磨圆柱滚子圆柱表面时，一方面，圆柱滚子可在研磨盘内外循环，具备大批量生产的能力；另一方面，在研磨加工区域，该设备可同时对大量圆柱滚子进行比较式加工，实现对直径较大的圆柱滚子的圆柱表面材料多去除，有利于圆柱滚子圆柱表面尺寸一致性的提高。
但是因研磨盘结构和加工原理的限制，上述双盘直槽研磨盘、研磨设备与研磨方法不具备对凸度圆柱滚子的滚动表面进行精加工的能力。
目前，凸度圆锥滚子滚动表面的精加工多采用无心贯穿式超精加工方法。其设备的加工部分由一对带螺旋滚道的超精螺旋导辊和一个(或一组)装有油石的超精头组成，凸度圆锥滚子由导辊支撑并驱动，在作旋转运动的同时又沿一与凸度圆锥滚子滚动表面素线相适应的轨迹作低速进给运动，在超精头以较低的压力将油石压向凸度圆锥滚子滚动表面的同时油石沿凸度圆锥滚子滚动表面的素线作高速微幅往复振动，对凸度圆锥滚子的滚动表面实施精加工。在无心贯穿式超精加工过程中，同一批次的凸度圆锥滚子依次贯穿通过加工区域并经受油石超精加工。
此外还有一种无心切入式超精加工方法，其设备的加工部分由一对平行布置的超精导辊和一个(或一组)装有油石的超精头组成，凸度圆锥滚子在导辊的支撑并驱动下作旋转运动，在超精头以较低的压力将油石压向凸度圆锥滚子滚动表面的同时油石沿一与凸度圆锥滚子滚动表面素线相适应的轨迹作低速进给运动和高速微幅往复振动，对凸度圆锥滚子的滚动表面实施精加工。在无心切入式超精加工过程中，同一批次的凸度圆锥滚子逐个进入加工区域并经受油石超精加工。
上述两种凸度圆锥滚子滚动表面超精加工方法存在以下两方面技术缺陷：一方面，加工过程中油石和导辊磨损状态随时间的变化不利于凸度圆锥滚子滚动表面形状精度和尺寸精度的提高；另一方面，由于超精加工设备同一时刻只对单个(或少数几个)凸度圆锥滚子进行加工，被加工凸度圆锥滚子滚动表面的材料去除量几乎不受同批次凸度圆锥滚子滚动表面直径差异的影响，因此用超精加工设备加工凸度圆锥滚子滚动表面很难有效改善被加工凸度圆锥滚子滚动表面的直径分散性。上述两方面的技术缺陷导致被加工凸度圆锥滚子滚动表面的形状精度和尺寸一致性提升受到制约。
中国专利公报，公布号CN1863642A公开了一种加工圆锥滚子的方法，其特征在于：所述圆锥滚子通过滚筒抛光或者滚桶抛光的方法精加工滚子表面。加工过程中滚子表面材料去除具有不确定性，该方法不能改善滚子的尺寸精度和直径分散性。

进一步地，本发明中的用于凸度滚子的滚动表面精加工的研磨设备，用于加工铁磁性材质的凸度滚子，其中的研磨盘套件采用前述的磁性研磨盘套件；该研磨设备中的滚子循环盘外系统还包括滚子退磁装置；所述滚子退磁装置设置在滚子循环盘外路径中的所述滚子输送系统中或滚子输送系统之前用于对被所述第二研磨盘基体内部的环状磁性结构的磁场磁化的铁磁性材质的被加工凸度滚子消磁。
本发明同时还提出了一种用于凸度滚子的滚动表面精加工的研磨方法，采用本发明所述的研磨设备，该研磨设备中的研磨盘套件为非磁性研磨盘套件，并包括以下步骤：
步骤一、第二研磨盘沿其轴线向第一研磨盘趋近，至第一研磨盘的内凹弧线沟槽工作面与第二研磨盘的螺旋槽工作面合围而成的每一个研磨加工区域的空间能够且仅能够容纳一个被加工凸度滚子；
步骤二、对应于研磨盘套件的回转方式一，第一研磨盘绕其轴线相对于第二研磨盘以1～10rpm低速回转；对应于研磨盘套件的回转方式二，第二研磨盘绕其轴线相对于第一研磨盘以1～10rpm低速回转；
步骤三、启动滚子输送系统、滚子整理机构和滚子送进机构；调整滚子送进机构的送进速度使之与第一研磨盘和第二研磨盘的相对回转速度相匹配；调整滚子输送系统的输送速度和滚子整理机构的整理速度使之与滚子送进机构的送进速度相匹配；从而建立被加工凸度滚子在第一研磨盘和第二研磨盘之间沿内凹弧线沟槽基线的圆弧进给与经由滚子循环盘外系统的收集、输送、整理、送进的循环；
步骤四、调整第一研磨盘与第二研磨盘的相对回转速度至5～60rpm的相对工作回转 速度，调整滚子送进机构的送进速度至工作送进速度使之与第一研磨盘和第二研磨盘的相对工作回转速度相匹配，调整滚子输送系统的输送速度和滚子整理机构的整理速度，使得上述滚子循环盘外系统中滚子收集装置、滚子输送系统、滚子整理机构和滚子送进机构各处的被加工凸度滚子的存量匹配、循环顺畅有序；
步骤五、对研磨加工区域加注研磨液；
步骤六、包括：
1)对于凸度圆柱滚子，第二研磨盘沿其轴线向第一研磨盘进一步趋近，使得研磨加工区域内的被加工凸度圆柱滚子的滚动表面分别与第一研磨盘的内凹弧线沟槽工作面发生十字交叉线接触和与第二研磨盘螺旋槽的工作面一发生线接触、被加工凸度圆柱滚子的一端面倒圆角与第二研磨盘螺旋槽的工作面二发生线接触；对于凸度圆锥滚子，第二研磨盘沿其轴线向第一研磨盘进一步趋近，使得研磨加工区域内的被加工凸度圆锥滚子的滚动表面分别与第一研磨盘的内凹弧线沟槽工作面的两对称侧面和第二研磨盘螺旋槽的工作面一发生线接触、被加工凸度圆锥滚子的大头端球基面或大头端倒圆角或小头端倒圆角与第二研磨盘螺旋槽的工作面二发生线接触；
2)对分布于研磨加工区域内的每个被加工凸度滚子平均施加0.5～2N的初始工作压力；被加工凸度滚子在第二研磨盘的螺旋槽工作面的摩擦驱动下绕自身轴线作连续旋转运动；与此同时，被加工凸度滚子在螺旋槽工作面的持续推挤作用下沿第一研磨盘的内凹弧线沟槽基线作圆弧进给运动；被加工凸度滚子的滚动表面开始经受第一研磨盘的内凹弧线沟槽工作面和第二研磨盘螺旋槽的工作面一的研磨加工；
步骤七、随着研磨加工过程稳定运行，对分布于研磨加工区域内的每个被加工凸度滚子逐渐增加工作压力至2～50N的正常工作压力；被加工凸度滚子保持步骤六的与第一研磨盘的内凹弧线沟槽工作面和第二研磨盘的螺旋槽工作面的接触关系、绕自身轴线的连续旋转运动以及沿内凹弧线沟槽基线的圆弧进给运动，其滚动表面继续经受第一研磨盘的内凹弧线沟槽工作面和第二研磨盘螺旋槽的工作面一的研磨加工；
步骤八、经过一段时间的研磨加工后，对被加工凸度滚子进行抽检；当被抽检的被加工凸度滚子的滚动表面的表面质量、形状精度和尺寸一致性尚未达到技术要求时，继续本步骤的研磨加工；当被抽检的被加工凸度滚子的滚动表面的表面质量、形状精度和尺寸一致性达到技术要求时，进入步骤九；
步骤九、逐渐减小工作压力并最终至零；停止滚子送进机构、滚子输送系统和滚子整理机构运行，调整第一研磨盘与第二研磨盘的相对转速至零；停止对研磨加工区域加注研磨液；第二研磨盘沿其轴线退回到非工作位置。
进一步地，本发明所述的研磨方法，采用的研磨设备中的研磨盘套件为上述磁性研磨盘套件，用于铁磁性材质的凸度滚子滚动表面的精加工，与前述研磨方法的步骤的不同之处在于：
步骤三、启动滚子退磁装置、滚子输送系统、滚子整理机构和滚子送进机构；调整滚子送进机构的送进速度使之与第一研磨盘和第二研磨盘的相对回转速度相匹配；调整滚子输送系统的输送速度和滚子整理机构的整理速度与滚子送进机构的送进速度相匹配；从而建立被加工凸度滚子在第一研磨盘和第二研磨盘之间沿内凹弧线沟槽基线的圆弧进给与经由滚子循环盘外系统的收集、输送、整理、送进的循环；
步骤六、包括：
1)第二研磨盘基体内部的环状磁性结构进入工作状态；对于凸度圆柱滚子，第二研磨盘沿其轴线向第一研磨盘进一步趋近，使得研磨加工区域内的被加工凸度圆柱滚子的滚动表面分别与第一研磨盘的内凹弧线沟槽工作面发生十字交叉线接触和与第二研磨盘螺旋槽的工作面一发生线接触、被加工凸度圆柱滚子的一端面倒圆角与第二研磨盘螺旋槽的工作面二发生线接触；对于凸度圆锥滚子，第二研磨盘沿其轴线向第一研磨盘进一步趋近，使得研磨加工区域内的被加工凸度圆锥滚子的滚动表面分别与第一研磨盘的内凹弧线沟槽工作面的两对称侧面和第二研磨盘螺旋槽的工作面一发生线接触、被加工凸度圆锥滚子的大头端球基面或大头端倒圆角或小头端倒圆角与第二研磨盘螺旋槽的工作面二发生线接触；
2)对分布于研磨加工区域内的每个被加工凸度滚子平均施加0.5～2N的初始工作压力；调整环状磁性结构的磁场强度，使得第二研磨盘的螺旋槽工作面对被加工凸度滚子绕自身轴线旋转所产生的滑动摩擦驱动力矩大于第一研磨盘的内凹弧线沟槽工作面对被加工凸度滚子绕自身轴线旋转所产生的滑动摩擦阻力矩，从而驱动被加工凸度滚子绕自身轴线作连续旋转运动；与此同时，被加工凸度滚子在螺旋槽工作面的持续推挤作用下沿第一研磨盘的内凹弧线沟槽基线作圆弧进给运动；被加工凸度滚子的滚动表面开始经受第一研磨盘的内凹弧线沟槽工作面和第二研磨盘螺旋槽的工作面一的研磨加工；
步骤九、逐渐减小工作压力并最终至零；停止滚子送进机构、滚子输送系统和滚子整理机构运行，调整第一研磨盘与第二研磨盘的相对转速至零；环状磁性结构切换至非工作状态，停止滚子退磁装置运行；停止对研磨加工区域加注研磨液；第二研磨盘沿其轴线退回到非工作位置。
本发明的研磨方法，其中，所用研磨设备中的研磨盘套件的第二研磨盘内部设置磁性结构的情况，有下述两种情形之一：
情形一、采用固结磨粒研磨方式研磨铁磁性材质的被加工凸度滚子时，在第二研磨盘的内部设置磁性结构，通过调整所述磁性结构的磁场强度，使得所述第二研磨盘的螺旋槽工作面对所述铁磁性材质的被加工凸度滚子绕自身轴线旋转所产生的滑动摩擦驱动力矩大于所述第一研磨盘的内凹弧线沟槽工作面对所述铁磁性材质的被加工凸度滚子绕自身轴线旋转所产生的滑动摩擦阻力矩，从而驱动所述铁磁性材质的被加工凸度滚子绕自身轴线连续旋转；
情形二、采用游离磨粒研磨方式研磨铁磁性材质的被加工凸度滚子时，所述第二研磨盘内置磁性结构，以增大所述第二研磨盘的螺旋槽工作面对所述铁磁性材质的被加工凸度滚子绕自身轴线旋转所产生的滑动摩擦驱动力矩，使得所述铁磁性材质的被加工凸度滚子绕自身轴线连续旋转不受所述第一研磨盘的内凹弧线沟槽工作面的材料与所述第二研磨盘的螺旋槽工作面的材料的匹配制约。
本发明的研磨方法，在所述第一研磨盘和第二研磨盘首次使用前，利用相同几何参数的被加工凸度滚子对所述第一研磨盘的内凹弧线沟槽工作面和第二研磨盘的螺旋槽工作面进行磨合；磨合方法与被加工凸度滚子的研磨方法相同；对于步骤八，对参与磨合的被加工凸度滚子进行抽检，当被抽检的被加工凸度滚子的滚动表面的表面质量、形状精度和尺寸一致性达到技术要求时，磨合过程进入步骤九；否则，继续步骤八。
与现有技术相比，本发明的有益效果是：
研磨加工过程中，在第一研磨盘的内凹弧线沟槽工作面与第二研磨盘的螺旋槽工作面合围而成的每一个研磨加工区域内，被加工凸度滚子的滚动表面分别与第一研磨盘的内凹弧线沟槽工作面和第二研磨盘的螺旋槽工作面发生接触，在第二研磨盘的螺旋槽工作面的摩擦驱动下被加工凸度滚子绕自身轴线旋转，被加工凸度滚子的滚动表面与第一研磨盘的内凹弧线沟槽工作面发生相对滑动，从而实现对被加工凸度滚子的滚动表面的研磨加工。
滚动表面的材料去除与滚动表面与内凹弧线沟槽工作面的接触应力直接相关，当较大直径的被加工凸度滚子的滚动表面或被加工凸度滚子的滚动表面的高点与内凹弧线沟槽工作面接触时，滚动表面与内凹弧线沟槽工作面的接触应力较大，接触处的滚动表面的材料去除量较大；当较小直径的被加工凸度滚子的滚动表面或被加工凸度滚子的滚动表面的低点与内凹弧线沟槽工作面接触时，滚动表面与内凹弧线沟槽工作面的接触应力较小，接触处的滚动表面的材料去除量较小。从而可实现凸度滚子的滚动表面的高点材料多去除、低点材料少去除，直径较大的凸度滚子的滚动表面的材料多去除、直径较小的凸度滚子的滚动表面的材料少去除。
由于第一研磨盘的内凹弧线沟槽和第二研磨盘的螺旋槽的开放性设计，研磨加工中存在被加工凸度滚子在第一研磨盘和第二研磨盘之间沿内凹弧线沟槽基线的圆弧进给与经由滚子循环盘外系统的收集、输送、整理、送进的循环，且经由滚子循环盘外系统时被加工凸度滚子原有的次序会被打乱。
一方面，第一研磨盘的内凹弧线沟槽和第二研磨盘的螺旋槽的开放性设计非常适应于大批量凸度滚子的滚动表面的精加工；另一方面，经由滚子循环盘外系统时被打乱的被加工凸度滚子的次序使得前述特征“凸度滚子的滚动表面的高点材料多去除、低点材料少去除，直径较大的凸度滚子的滚动表面的材料多去除、直径较小的凸度滚子的滚动表面的材料少去除”可以扩散至整个加工批次，从而可提高整个批次的凸度滚子的滚动表面的形状精度和尺寸一致性；再一方面，第一研磨盘的内凹弧线沟槽与第二研磨盘的螺旋槽有数十个至数百个之多的交会处，即同时有数十个至数百个被加工凸度滚子参与研磨，从而可以提高凸度滚子的滚动表面的加工效率，降低加工成本。
而且，由于第二研磨盘内部磁性结构的设置，在铁磁性材质的被加工凸度滚子的力平衡体系中引入了第二研磨盘的螺旋槽工作面对铁磁性材质的被加工凸度滚子的磁吸力，而所述磁吸力独立于研磨加工时通过第一研磨盘和第二研磨盘的相对趋近施加于铁磁性材质的被加工凸度滚子的工作压力，使得条件“第二研磨盘的螺旋槽工作面对所述铁磁性材质的被加工凸度滚子绕自身轴线旋转所产生的滑动摩擦驱动力矩大于第一研磨盘的内凹弧线沟槽工作面对所述铁磁性材质的被加工凸度滚子绕自身轴线旋转所产生的滑动摩擦阻力矩”更容易实现。

对应于主机构型三，设置有两套主轴装置18，其中一套主轴装置18安装在所述基座11上，通过与其连接的所述下托盘16驱动所述第一研磨盘21绕其轴线回转，另一套主轴装置18安装在所述滑台14上，通过与其连接的所述上托盘15驱动所述第二研磨盘22绕其轴线回转；所述两套主轴装置18均设置有锁死机构，同一时间只允许所述第一研磨盘21和第二研磨盘22之一回转，而另一研磨盘处于周向锁死状态。
当研磨设备的研磨盘套件2以方式一回转进行研磨加工时，所述第一研磨盘21与第二研磨盘22的相对运动与所述主机构型一相同；所述滚子送进机构45的结构、安装位置和作用与所述主机构型一相同；被加工凸度圆锥滚子3的循环路径和研磨过程与所述主机构型一相同。

如图3-10(a)和图3-11(a)所示，研磨加工时，被加工凸度圆锥滚子3从所述第一研磨盘的各内凹弧线沟槽入口21118进入研磨加工区域，从所述第一研磨盘的各内凹弧线沟槽出口21119离开研磨加工区域，再从所述第一研磨盘的各内凹弧线沟槽出口21119，顺次经由所述滚子收集装置41、滚子输送系统43、滚子整理机构44和滚子送进机构45，进入所述第一研磨盘的各内凹弧线沟槽入口21118，形成被加工凸度圆锥滚子3在所述第一研磨盘21和第二研磨盘22之间沿所述内凹弧线沟槽基线21116的圆弧进给与经由所述滚子循环盘外系统4的收集、输送、整理、送进的循环。所述循环在所述研磨盘套件2之外的路径为从所述第一研磨盘的各内凹弧线沟槽出口21119，顺次经由所述滚子收集装置41、滚子输送系统43、滚子整理机构44和滚子送进机构45，进入所述第一研磨盘的各内凹弧线沟槽入口21118，定义所述路径为滚子循环盘外路径。
采用游离磨粒研磨方式时，可通过分别选择所述第一研磨盘的内凹弧线沟槽工作面21111的材料和所述第二研磨盘的螺旋槽工作面22111的材料，使得在研磨加工工况下所述第二研磨盘的螺旋槽工作面22111的材料与被加工凸度圆锥滚子3的材料组成的摩擦副对被加工凸度圆锥滚子3绕自身轴线31旋转所产生的滑动摩擦驱动力矩大于所述第一研磨盘的内凹弧线沟槽工作面21111的材料与被加工凸度圆锥滚子3的材料组成的摩擦副对被加工凸度圆锥滚子3绕自身轴线31旋转所产生的滑动摩擦阻力矩，从而驱动被加工凸度圆锥滚子3绕自身轴线31连续旋转。
当所述第一研磨盘的内凹弧线沟槽工作面21111的材料选择聚四氟乙烯、所述第二研磨盘的螺旋槽工作面22111的材料选择聚甲基丙烯酸甲酯时，可实现GCr15、G20CrNi2MoA、Cr4Mo4V等材质的被加工凸度圆锥滚子3绕自身轴线31连续旋转。
研磨设备实施例四：一种用于铁磁性材质(如GCr15、G20CrNi2MoA、Cr4Mo4V等)的凸度圆锥滚子滚动表面精加工的研磨设备。
该研磨设备包括主机、研磨盘套件和滚子循环盘外系统4，与研磨设备实施例三所述的研磨设备的不同之处在于：其中的研磨盘套件采用如研磨盘套件实施例四所述的研磨盘套件，并且在所述的滚子循环盘外系统4中还包括有滚子退磁装置42。
如图4-3(a)和图4-3(b)所示，所述滚子循环盘外系统4，包括滚子收集装置41、滚子退磁装置42、滚子输送系统43、滚子整理机构44和滚子送进机构45。
如图4-3(a)、图4-3(b)、图4-4和图4-5所示，所述滚子退磁装置42设置在所述滚子循环盘外路径中的所述滚子输送系统43中或滚子输送系统43之前用于对被所述第二研磨盘基体内部的环状磁性结构226的磁场磁化的铁磁性材质的被加工凸度圆锥滚子3消磁，以避免所述铁磁性材质的被加工凸度圆锥滚子3在通过滚子输送系统43或滚子整理机构44时发生团聚。
如图4-1(a)、图4-1(b)、图4-2(a)和图4-2(b)所示，研磨加工时，通过调整所述环状磁性结构226的磁场强度，以在所述第二研磨盘正面221附近形成足够强的磁场227，并使所述第二研磨盘的螺旋槽工作面22111对所述铁磁性材质的被加工凸度圆锥滚子3产生足 够强的磁吸力，以使所述第二研磨盘的螺旋槽工作面22111对所述铁磁性材质的被加工凸度圆锥滚子3绕自身轴线31旋转所产生的滑动摩擦驱动力矩大于所述第一研磨盘的内凹弧线沟槽工作面21111对所述铁磁性材质的被加工凸度圆锥滚子3绕自身轴线31旋转所产生的滑动摩擦阻力矩，从而驱动所述被加工凸度圆锥滚子3绕自身轴线31连续旋转。
所述第二研磨盘基体内部的环状磁性结构226处于非工作状态时，所述第二研磨盘正面221附近的磁场227消失或减弱，所述第二研磨盘的螺旋槽工作面22111对所述铁磁性材质的被加工凸度圆锥滚子3产生的磁吸力消失或减弱。
所述主机存在三种构型，对应于主机构型二，如图4-2(b)所示，所述主轴装置18安装在所述滑台14上，通过与其连接的所述上托盘15驱动所述第二研磨盘22绕其轴线回转；所述下托盘16安装在所述基座11上，所述第一研磨盘21和下托盘16不回转。用于驱动所述第二研磨盘22回转的主轴装置18的主轴上安装有导电滑环，用于给处于回转状态的所述第二研磨盘基体内部的环状磁性结构226提供电力。
本发明实施时，可采用游离磨粒研磨方式或固结磨粒研磨方式。
当采用固结磨粒研磨时，所述第一研磨盘的内凹弧线沟槽工作面21111由固结磨粒材料制成。
采用固结磨粒研磨方式研磨铁磁性材质的被加工凸度圆锥滚子3时，通过调整所述环状磁性结构226的磁场强度，使所述第二研磨盘的螺旋槽工作面22111对所述铁磁性材质的被加工凸度圆锥滚子3产生足够强的磁吸力，以使所述第二研磨盘的螺旋槽工作面22111对所述铁磁性材质的被加工凸度圆锥滚子3绕自身轴线31旋转所产生的滑动摩擦驱动力矩大于所述第一研磨盘的内凹弧线沟槽工作面21111对所述铁磁性材质的被加工凸度圆锥滚子3绕自身轴线31旋转所产生的滑动摩擦阻力矩，从而驱动所述铁磁性材质的被加工凸度圆锥滚子3绕自身轴线31连续旋转。
采用游离磨粒研磨方式研磨铁磁性材质的被加工凸度圆锥滚子3时，调整所述环状磁性结构226的磁场强度，以增大所述第二研磨盘的螺旋槽工作面22111对所述铁磁性材质的被加工凸度圆锥滚子3绕自身轴线31旋转所产生的滑动摩擦驱动力矩。此时所述铁磁性材质的被加工凸度圆锥滚子3绕自身轴线31连续旋转可不受所述第一研磨盘的内凹弧线沟槽工作面21111的材料与所述第二研磨盘的螺旋槽工作面22111的材料的匹配制约。
研磨方法实施例一：一种用于凸度圆柱滚子滚动表面精加工的研磨方法。
该研磨方法采用如研磨设备实施例一所述的研磨设备，下面结合附图1-1至图1-11(b)对本实施例研磨方法进行详细描述，该研磨方法包括以下步骤：
步骤一、第二研磨盘22沿其轴线向第一研磨盘21趋近，至第一研磨盘正面上连接相邻内凹弧线沟槽的过渡面2112与第二研磨盘正面上连接相邻螺旋槽的过渡面2212尽可能接近、但研磨加工区域内的被加工凸度圆柱滚子3尚未同时与第一研磨盘的内凹弧线沟槽工作面21111发生十字交叉线接触和与第二研磨盘螺旋槽的工作面一221111和工作面二221112发生线接触，即第一研磨盘的内凹弧线沟槽工作面21111与第二研磨盘的螺旋槽工作面22111合围而成的每一个研磨加工区域的空间能够且仅能够容纳一个被加工凸度圆柱滚子3。
步骤二、对应于研磨盘套件2的回转方式一，驱动第一研磨盘21绕其轴线相对于第二研磨盘22低速回转；对应于研磨盘套件2的回转方式二，第二研磨盘22绕其轴线相对 于第一研磨盘21低速回转。根据第一研磨盘21和第二研磨盘22的外径尺寸回转速度为1～10rpm，第一研磨盘21和第二研磨盘22的回转方向需根据第二研磨盘的螺旋槽2211的旋向及螺旋槽入口22118、螺旋槽出口22119的位置确定，以保证被加工凸度圆柱滚子3可以自第一研磨盘的各内凹弧线沟槽入口21118进入内凹弧线沟槽2111和自对应的各内凹弧线沟槽出口的21119离开内凹弧线沟槽2111。
步骤三、启动滚子输送系统43、滚子整理机构44和滚子送进机构45；调整滚子送进机构45的送进速度使之与第一研磨盘21和第二研磨盘22的相对回转速度相匹配，以保证当第二研磨盘的各螺旋槽入口22118与第一研磨盘的各内凹弧线沟槽入口21118发生交会时，在滚子送进机构45的作用下将分别有一个被加工凸度圆柱滚子3进入螺旋槽入口22118与内凹弧线沟槽入口21118的每一入口交会处；调整滚子输送系统43的输送速度和滚子整理机构44的整理速度使之与滚子送进机构45的送进速度相匹配，使被加工凸度圆柱滚子3经由滚子输送系统43和滚子整理机构44，在滚子送进机构45的作用下及时进入各入口交会处；进入入口交会处的被加工凸度圆柱滚子3随后因第一研磨盘21和第二研磨盘22的相对回转在第二研磨盘的螺旋槽入口22118处的螺旋槽工作面22111的推挤作用下进入研磨加工区域；进入研磨加工区域的被加工凸度圆柱滚子3在第二研磨盘的螺旋槽工作面22111的持续推挤作用下沿第一研磨盘的内凹弧线沟槽基线21116作圆弧进给运动，贯穿通过内凹弧线沟槽2111，并从第二研磨盘的各螺旋槽出口22119与第一研磨盘的各内凹弧线沟槽出口21119的出口交会处离开研磨加工区域；离开研磨加工区域的被加工凸度圆柱滚子3经由滚子收集装置41、滚子输送系统43和滚子整理机构44，原有的次序被打乱后再次在滚子送进机构45的作用下依次进入入口交会处；从而建立被加工凸度圆柱滚子3在第一研磨盘21和第二研磨盘22之间沿内凹弧线沟槽基线21116的圆弧进给与经由滚子循环盘外系统4的收集、输送、整理、送进的循环。
步骤四、调整第一研磨盘21与第二研磨盘22的相对回转速度至相对工作回转速度，根据第一研磨盘21和第二研磨盘22的外径尺寸相对工作回转速度为5～60rpm，调整滚子送进机构45的送进速度至工作送进速度使之与第一研磨盘21和第二研磨盘22的相对工作回转速度相匹配，调整滚子输送系统43的输送速度和滚子整理机构44的整理速度，使得上述滚子循环盘外系统4中滚子收集装置41、滚子输送系统43、滚子整理机构44和滚子送进机构45各处的被加工凸度圆柱滚子3的存量匹配、循环顺畅有序。
步骤五、对研磨加工区域加注研磨液。
步骤六、第二研磨盘22沿其轴线向第一研磨盘21进一步趋近，使得研磨加工区域内的被加工凸度圆柱滚子的滚动表面32分别与第一研磨盘的内凹弧线沟槽工作面21111发生十字交叉线接触和与第二研磨盘螺旋槽的工作面一221111发生线接触、被加工凸度圆柱滚子的一端面倒圆角与第二研磨盘螺旋槽的工作面二221112发生线接触，并对分布于研磨加工区域内的每个被加工凸度圆柱滚子3施加初始工作压力，根据被加工凸度圆柱滚子3的直径尺寸初始工作压力平均为0.5～2N。第二研磨盘的螺旋槽工作面22111对被加工凸度圆柱滚子3绕自身轴线31旋转所产生的滑动摩擦驱动力矩大于第一研磨盘的内凹弧线沟槽工作面21111对被加工凸度圆柱滚子3绕自身轴线31旋转所产生的滑动摩擦阻力矩，被加工凸度圆柱滚子3绕自身轴线31作连续旋转运动；与此同时，被加工凸度圆柱滚子3在第二研磨盘的螺旋槽工作面22111的持续推挤作用下沿第一研磨盘的内凹弧线 沟槽基线21116作圆弧进给运动。被加工凸度圆柱滚子滚动表面32开始经受第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘螺旋槽的工作面一221111的研磨加工。
步骤七、随着研磨加工过程稳定运行，对分布于研磨加工区域内的每个被加工凸度圆柱滚子3逐渐增加工作压力至正常工作压力，根据被加工凸度圆柱滚子3的直径尺寸正常工作压力平均为2～50N。被加工凸度圆柱滚子3保持步骤六的与第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘的螺旋槽工作面22111的接触关系、绕自身轴线31的连续旋转运动以及沿第一研磨盘的内凹弧线沟槽基线21116的圆弧进给运动，其滚动表面32继续经受第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘螺旋槽的工作面一221111的研磨加工。
步骤八、经过一段时间的研磨加工后，对被加工凸度圆柱滚子3进行抽检；当被抽检的被加工凸度圆柱滚子的滚动表面32的表面质量、形状精度和尺寸一致性尚未达到技术要求时，继续本步骤的研磨加工；当被抽检的被加工凸度圆柱滚子的滚动表面32的表面质量、形状精度和尺寸一致性达到技术要求时，进入步骤九。
步骤九、逐渐减小工作压力并最终至零；停止滚子送进机构45、滚子输送系统43和滚子整理机构44运行，调整第一研磨盘21与第二研磨盘22的相对转速至零；停止对研磨加工区域加注研磨液；驱动第二研磨盘22沿其轴线退回到非工作位置。收集循环中各处的被加工凸度圆柱滚子3，至此，研磨加工过程结束。
可以理解到，上述的步骤及顺序不仅可以进行如实例所述的组合，而且可以进行其它的组合使用，这不超出本发明的范围。
由于针对特定被加工凸度圆柱滚子3的参数设计加工的所述第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘的螺旋槽工作面22111不可避免地存在制造误差，且所述第一研磨盘21和第二研磨盘22在研磨设备上安装时也会存在安装误差。这些制造误差和安装误差可能会导致研磨加工时被加工凸度圆柱滚子3与所述第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘的螺旋槽工作面22111的接触状态与理想情况存在差异。
为了减小此种差异，在所述第一研磨盘21和第二研磨盘22首次使用前，推荐利用相同几何参数的被加工凸度圆柱滚子3对所述第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘的螺旋槽工作面22111进行磨合。磨合方法与被加工凸度圆柱滚子3的研磨方法相同；对于步骤八，对参与磨合的被加工凸度圆柱滚子3进行抽检，当被抽检的被加工凸度圆柱滚子的滚动表面32的表面质量、形状精度和尺寸一致性达到技术要求时，磨合过程进入步骤九；否则，继续步骤八。
本实施例研磨方法不限用于凸度圆柱滚子滚动表面精加工，还可用于球面滚子等具有凸度圆柱滚子圆弧素线或近似圆弧素线特征的回转体零件的外径表面精加工，这不超出本发明的范围。
研磨方法实施例二：一种用于铁磁性材质(如GCr15、G20CrNi2MoA、Cr4Mo4V等)的凸度圆柱滚子滚动表面精加工的研磨方法。
该研磨方法采用如研磨设备实施例二所述的研磨设备，该研磨设备中的研磨盘套件的第二研磨盘22内部设置有环状磁性结构226，该研磨设备中的滚子循环盘外系统4还包括有滚子退磁装置42，滚子退磁装置42设置在滚子盘外循环路径中的滚子输送系统43中或滚子输送系统43之前用于对被第二研磨盘内置的环状磁性结构226的磁场磁化的铁 磁性材质的被加工凸度圆柱滚子消磁，以避免铁磁性材质的被加工凸度圆柱滚子在通过滚子输送系统43或滚子整理机构44时发生团聚，与研磨方法实施例一所述的研磨过程的不同之处在于：
步骤三中同时启动滚子退磁装置42。
步骤六为：第二研磨盘基体内部的环状磁性结构226进入工作状态；第二研磨盘22沿其轴线向第一研磨盘21进一步趋近，使得研磨加工区域内的被加工凸度圆柱滚子的滚动表面32分别与第一研磨盘的内凹弧线沟槽工作面21111发生十字交叉线接触和与第二研磨盘螺旋槽的工作面一221111发生线接触、被加工凸度圆柱滚子的一端面倒圆角与第二研磨盘螺旋槽的工作面二221112发生线接触，并对分布于研磨加工区域内的每个被加工凸度圆柱滚子3施加初始工作压力，根据被加工凸度圆柱滚子3的直径尺寸初始工作压力平均为0.5～2N。调整环状磁性结构226的磁场强度，使得第二研磨盘的螺旋槽工作面22111对铁磁性材质的被加工凸度圆柱滚子3绕自身轴线31旋转所产生的滑动摩擦驱动力矩大于第一研磨盘的内凹弧线沟槽工作面21111对铁磁性材质的被加工凸度圆柱滚子3绕自身轴线31旋转所产生的滑动摩擦阻力矩，从而驱动铁磁性材质的被加工凸度圆柱滚子3绕自身轴线31作连续旋转运动；与此同时，被加工凸度圆柱滚子3在第二研磨盘的螺旋槽工作面22111的持续推挤作用下沿第一研磨盘的内凹弧线沟槽基线21116作圆弧进给运动。被加工凸度圆柱滚子的滚动表面32开始经受第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘螺旋槽的工作面一221111的研磨加工。
步骤九为：逐渐减小工作压力并最终至零；停止滚子送进机构45、滚子输送系统43和滚子整理机构44运行，调整第一研磨盘21与第二研磨盘22的相对转速至零；环状磁性结构226切换至非工作状态，停止滚子退磁装置42运行；停止对研磨加工区域加注研磨液；驱动第二研磨盘22沿其轴线退回到非工作位置。收集循环中各处的被加工凸度圆柱滚子3，至此，研磨加工过程结束。
本实施例研磨方法不限用于铁磁性材质的凸度圆柱滚子滚动表面精加工，还可用于球面滚子等具有凸度圆柱滚子圆弧素线或近似圆弧素线特征的铁磁性材质的回转体零件的外径表面精加工，这不超出本发明的范围。
研磨方法实施例三：一种用于凸度圆锥滚子滚动表面精加工的研磨方法。
该研磨方法采用如研磨设备实施例三所述的研磨设备，下面结合附图3-1至图3-11(b)对本实施例研磨方法进行详细描述，该研磨方法包括以下步骤：
步骤一、第二研磨盘22沿其轴线向第一研磨盘21趋近，至第一研磨盘正面上连接相邻内凹弧线沟槽的过渡面2112与第二研磨盘正面上连接相邻螺旋槽的过渡面2212尽可能接近、但研磨加工区域内的被加工凸度圆锥滚子3尚未同时与第一研磨盘的内凹弧线沟槽工作面21111的两对称侧面、第二研磨盘螺旋槽的工作面一221111和工作面二221112发生线接触，即第一研磨盘的内凹弧线沟槽工作面21111与第二研磨盘的螺旋槽工作面合围而成的每一个研磨加工区域的空间能够且仅能够容纳一个被加工凸度圆锥滚子3。
步骤二、对应于研磨盘套件2的回转方式一，驱动第一研磨盘21绕其轴线相对于第二研磨盘22低速回转；对应于研磨盘套件2的回转方式二，第二研磨盘22绕其轴线223相对于第一研磨盘21低速回转。根据第一研磨盘21和第二研磨盘22的外径尺寸回转速度为1～10rpm，第一研磨盘21和第二研磨盘22的回转方向需根据第二研磨盘的螺旋槽 2211的旋向及螺旋槽入口22118、螺旋槽出口22119的位置确定，以保证被加工凸度圆锥滚子3可以自第一研磨盘的各内凹弧线沟槽入口21118进入内凹弧线沟槽2111和自对应的各内凹弧线沟槽出口21119离开内凹弧线沟槽2111。
步骤三、启动滚子输送系统43、滚子整理机构44和滚子送进机构45；调整滚子送进机构45的送进速度使之与第一研磨盘21和第二研磨盘22的相对回转速度相匹配，以保证当第二研磨盘的各螺旋槽入口22118与第一研磨盘的各内凹弧线沟槽入口21118发生交会时，在滚子送进机构45的作用下将分别有一个被加工凸度圆锥滚子3进入螺旋槽入口22118与内凹弧线沟槽入口21118的每一入口交会处；调整滚子输送系统43的输送速度和滚子整理机构44的整理速度使之与滚子送进机构45的送进速度相匹配，使被加工凸度圆锥滚子3经由滚子输送系统43和滚子整理机构44，在滚子送进机构45的作用下及时进入各入口交会处；进入入口交会处的被加工凸度圆锥滚子3随后因第一研磨盘21和第二研磨盘22的相对回转在第二研磨盘的螺旋槽入口22118处的螺旋槽工作面22111的推挤作用下进入研磨加工区域；进入研磨加工区域的被加工凸度圆锥滚子3在第二研磨盘的螺旋槽工作面22111的持续推挤作用下沿第一研磨盘的内凹弧线沟槽基线21116作圆弧进给运动，贯穿通过内凹弧线沟槽2111，并从第二研磨盘的各螺旋槽出口22119与第一研磨盘的各内凹弧线沟槽出口21119的出口交会处离开研磨加工区域；离开研磨加工区域的被加工凸度圆锥滚子3经由滚子收集装置41、滚子输送系统43和滚子整理机构44，原有的次序被打乱后再次在滚子送进机构45的作用下依次进入入口交会处；从而建立被加工凸度圆锥滚子3在第一研磨盘21和第二研磨盘22之间沿内凹弧线沟槽基线21116的圆弧进给经由滚子循环盘外系统4的收集、输送、整理、送进的循环。
步骤四、调整第一研磨盘21与第二研磨盘22的相对回转速度至相对工作回转速度，根据第一研磨盘21和第二研磨盘22的外径尺寸相对工作回转速度为5～60rpm，调整滚子送进机构45的送进速度至工作送进速度使之与第一研磨盘21和第二研磨盘22的相对工作回转速度相匹配，调整滚子输送系统43的输送速度和滚子整理机构44的整理速度，使得上述滚子循环盘外系统4中滚子收集装置41、滚子输送系统43、滚子整理机构44和滚子送进机构45各处的被加工凸度圆锥滚子3的存量匹配、循环顺畅有序。
步骤五、对研磨加工区域加注研磨液。
步骤六、第二研磨盘22沿其轴线向第一研磨盘21进一步趋近，使得研磨加工区域内的被加工凸度圆锥滚子的滚动表面32分别与第一研磨盘的内凹弧线沟槽工作面21111的两对称侧面和第二研磨盘螺旋槽的工作面一221111发生线接触、被加工凸度圆锥滚子的大头端球基面342(或大头端倒圆角341或小头端倒圆角331)与第二研磨盘螺旋槽的工作面二221112发生线接触，并对分布于研磨加工区域内的每个被加工凸度圆锥滚子3施加初始工作压力，根据被加工凸度圆锥滚子3的直径尺寸初始工作压力平均为0.5～2N。第二研磨盘的螺旋槽工作面22111对被加工凸度圆锥滚子3绕自身轴线31旋转所产生的滑动摩擦驱动力矩大于第一研磨盘的内凹弧线沟槽工作面21111对被加工凸度圆锥滚子3绕自身轴线31旋转所产生的滑动摩擦阻力矩，被加工凸度圆锥滚子3绕自身轴线31作连续旋转运动；与此同时，被加工凸度圆锥滚子3在第二研磨盘的螺旋槽工作面22111的持续推挤作用下沿第一研磨盘的内凹弧线沟槽基线21116作圆弧进给运动。被加工凸度圆锥滚子的滚动表面32开始经受第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘螺旋 槽的工作面一221111的研磨加工。
步骤七、随着研磨加工过程稳定运行，对分布于研磨加工区域内的每个被加工凸度圆锥滚子3逐渐增加工作压力至正常工作压力，根据被加工凸度圆锥滚子3的直径尺寸正常工作压力平均为2～50N。被加工凸度圆锥滚子3保持步骤六的与第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘的螺旋槽工作面22111的线接触关系、绕自身轴线31的连续旋转运动以及沿第一研磨盘的内凹弧线沟槽基线21116的圆弧进给运动，其滚动表面32继续经受第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘螺旋槽的工作面一221111的研磨加工。
步骤八、经过一段时间的研磨加工后，对被加工凸度圆锥滚子3进行抽检；当被抽检的被加工凸度圆锥滚子的滚动表面32的表面质量、形状精度和尺寸一致性尚未达到技术要求时，继续本步骤的研磨加工；当被抽检的被加工凸度圆锥滚子的滚动表面32的表面质量、形状精度和尺寸一致性达到技术要求时，进入步骤九。
步骤九、逐渐减小工作压力并最终至零；停止滚子送进机构45、滚子输送系统43和滚子整理机构44运行，调整第一研磨盘21与第二研磨盘22的相对转速至零；停止对研磨加工区域加注研磨液；驱动第二研磨盘22沿其轴线退回到非工作位置。收集循环中各处的被加工凸度圆锥滚子3，至此，研磨加工过程结束。
可以理解到，上述的步骤及顺序不仅可以进行如实例所述的组合，而且可以进行其它的组合使用，这不超出本发明的范围。
由于针对特定被加工凸度圆锥滚子3的参数设计加工的所述第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘的螺旋槽工作面22111不可避免地存在制造误差，且所述第一研磨盘21和第二研磨盘22在研磨设备上安装时也会存在安装误差。这些制造误差和安装误差可能会导致研磨加工时被加工凸度圆锥滚子3与所述第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘的螺旋槽工作面22111的接触状态与理想情况存在差异。
为了减小此种差异，在所述第一研磨盘21和第二研磨盘22首次使用前，推荐利用相同几何参数的被加工凸度圆锥滚子3对所述第一研磨盘的内凹弧线沟槽工作面21111和第二研磨盘的螺旋槽工作面22111进行磨合。磨合方法与被加工凸度圆锥滚子3的研磨方法相同；对于步骤八，对参与磨合的被加工凸度圆锥滚子3进行抽检，当被抽检的被加工凸度圆锥滚子的滚动表面32的表面质量、形状精度和尺寸一致性达到技术要求时，磨合过程进入步骤九；否则，继续步骤八。

步骤九为：逐渐减小工作压力并最终至零；停止滚子送进机构45、滚子输送系统43和滚子整理机构44运行，调整第一研磨盘21与第二研磨盘22的相对转速至零；环状磁性结构226切换至非工作状态，停止滚子退磁装置42运行；停止对研磨加工区域加注研磨液；驱动第二研磨盘22沿其轴线退回到非工作位置。收集循环中各处的被加工凸度圆锥滚子3，至此，研磨加工过程结束。
