PURPOSE:To efficiently burnish the stepped part of a gear without need for using a highly accurate die by providing an equipment having an intermeshing device of gears without requiring any expensive rolling machine. CONSTITUTION:A gear 11, in which the stepped parts 10 are gear cut, is mounted on the mandrel 6 of a gear intermeshing device 1. The mandrel 6, on which a workpiece 12, or the gear 11 is mounted, is provided between a rotary shaft 2 and a center retainer 3 and centered, and a work carry 9a is engaged with the engaging part (not shown in figure) of a plate 4. And, the tooth part 16 of a master gear 9 is brought in contact with the stepped part 10 of the workpiece 12 and a load of about 3 ton is applied. Then, the shaft 2 is rotated, the workpiece 12 is rotated, and the stepped part 10 is burnished through the tooth part 16 of a master gear 9. |
