摘要: 提出圆锥滚子凸度贯穿式超精研修形加工的一种新型的锥柱匹配的导辊配置方式,其后导辊是圆柱形形面,可通用于不同型号的滚子;其前导辊采用匹配的专用螺旋锥形形面。对锥柱匹配导辊配置方式的滚子姿态进行简化分析表明,这是一种具有特定滚子姿态的斜置贯穿式超精研,可以获得凸度。依据共轭曲面原理建立斜置贯穿式超精研导辊的理想形面方程,通过数值计算分析锥柱匹配导辊形面和相应滚子姿态问题,结果表明,一般斜置贯穿式超精研前后导辊理想形面的轴向截形均为相对于导辊轴线倾斜的轻微内凹曲线,但存在特定的滚子姿态,可以使后导辊形面曲线不倾斜而只有轻微内凹;锥柱匹配导辊配置方式中,后导辊的圆柱面是近似形面,但其形状误差很小,一般不超过4 μm,对滚子的支撑稳定性影响不大。给出了锥柱匹配导辊配置方式中圆柱导辊形状误差、锥形导辊形面参数以及相应滚子姿态参数的精确计算方法。

Abstract: A new type of settings with the cone-cylinder match guide rollers for the through-feed superfinishing of tapered rollers with crown is proposed. The rear guide roller adopts cylindrical surface, so as to be shared by the different specifications of tapered rollers. The front guide roller adopts the spiral and conical surface, and is specially matched for only one specification of the tapered roller. The simplified analysis on the roller posture in corresponding to the cone-cylinder match guide rollers is performed. The result shows that this is a through-feed superfinishing with specifically oblique roller posture and the roller crown can be obtained. According to the principle of conjugating surfaces, the equations of the ideal surface profile of the guide rollers for common through-feed superfinishing with oblique roller posture are established. The surface profiles as well as the roller posture in corresponding to the cone-cylinder match guide rollers are analyzed by numerical calculation according to the equations, and some conclusions are drown as follows:For common through-feed superfinishing with oblique roller posture, the ideal surface profile of the front guide roller and the rear one are usually slightly concave curves which are oblique with respect to the axis of the guide rollers, but there is a specifically oblique roller posture which can make the curve of the rear guide roller change to be not oblique but only slightly concave; For the type of settings with cone-cylinder match guide rollers, the cylindrical surface is a approximation of the ideal surface of the rear guide roller,and there is shape error on it; The shape error is usually not more than 4 μm, and there is no obvious effect on the support stability of the rollers. The exact methods to calculating the shape error of the cylindrical guide roller, the surface profile parameters of the cone guide roller and the roller posture parameters are given.
