Title:
SURFACE PROCESSING METHOD AND SURFACE PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2018144127
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a surface processing method and a surface processing device, which achieve high fatigue strength by obtaining high residual compression stress.SOLUTION: A cover member 3 for surrounding an outer peripheral surface 10a of an annular gear 10 and a jig arranged at an inside in a radial direction of the annular gear 10 (workpiece) are synchronously and relatively moved in a circumferential direction Y of the annular gear 10 in a state in which a tension load is applied to a part 10P in the circumferential direction Y of the annular gear 10, by applying a pressure by a pressure roller 23 (pressure part) of the jig. A projection device 5 projects a projection material to an outer peripheral surface 10a of the annular gear 10 in the part 10P moved in the circumferential direction Y, through an opening part 33 of the cover member 3.SELECTED DRAWING: Figure 3
