Title: Gear dedendum working device
Inventor: NAKAMURA SHIGETOSHI
IPC: B23F19/00
Filed: 1990-11-30
Abstract: PURPOSE:To give a uniform residual compressive stress to a dedendum by setting a crossed axes angle between the axes of a dedendum roll means and a gear to be worked to an angle with which the number of contact points of a pressurizing gear with the dedendum is reduced to one or less, and providing the dedendum roll means, which is reciprocated freely and relatively, along the axis of the gear to be worked. CONSTITUTION:A rotating means provided on a fixed table 13 is driven with a specified pressurizing force F energized to a gear to be worked W. Since a helix angle beta' of a pressurizing gear 19 is set to an angle determined by a helix angle beta of the gear to be worked W and their crossed axes angle thetato reduce the number of contact points of the pressurizing gear 19 with a dedendum 1 to one or less, the number of contact points of a dedendum roll tool 12 with the gear to be worked W is always one or less irrespective of their rotating position. Accordingly, when the dedendum 1 is worked to increase the strength under a specified pressurizing force F, the pressurizing force for each contact point becomes constant. Thus a residual compressive stress to be given to the dedendum 1 becomes even to uniform the mechanical strength of the gear to be worked W.
