【発明の名称】転がり軸受用ローラの製造方法
Document Type and Number:
Japanese Patent JP2897334
Kind Code:
B2
Abstract:
PURPOSE:To obtain the uniform quality of the peripheral surface by applying superfinishing work to the peripheral surface of a roller material after grinding work, smoothing the surface in the axial and circumferential directions and setting the surface roughness in the circumferential direction nearly equal to or slightly larger than the surface roughness in the axial direction, through tumbling. CONSTITUTION:When grinding work is carried out on the peripheral surface of the material of a roller 5, the surface roughness in the axial direction B on the peripheral surface becomes larger than the surface roughness in the circumferential direction A. Then, the superfinishing is applied to the peripheral surface in the second working, and smooth surfaces are formed in the axial and circumferential directions B and A, and the shape precision is secured, and the peripheral surface is finally finished through tumbling. Accordingly, microslip is effectively prevented, and the dispersion of the quality of the peripheral surface can be eliminated.
