    • Provided is a gear grinding method capable of improving processing accuracy and easily adjusting the crowning shape by simplifying a processing operation. To this end, a work piece (W) is ground by a gear-shaped grinding stone (11) having a drum shape such that crowning along a tooth trace direction is applied to the work piece (W) by applying a relative feed in a feed direction (D1) that intersects a work piece rotation axis (C1) at a predetermined first diagonal angle (θ1) between the work piece (W) and the gear-shaped grinding stone (11) while the work piece (W) and the gear-shaped grinding stone (11) are synchronously rotated in the state of being engaged so as to have a predetermined crossed axes angle (Σ), and the curvature in a grinding stone width direction, which defines the drum shape of the gear-shaped grinding stone (11), and the first diagonal angle (θ1) are set according to the crowning shape of the work piece (W).
    • 本发明提供一种齿轮磨削方法,其能够通过简化加工操作来提高加工精度并且容易地调整凸面形状。 为此,工件(W)通过具有鼓形状的齿轮形磨石(11)磨削,使得通过将相对进给到工件(W)中而沿工件(W)施加沿着齿线方向的凸面 (W)和齿轮状磨石(11)之间以预定的第一对角角(θ1)与工件旋转轴线(C1)相交的进给方向(D1) 在啮合的状态下,齿轮状磨石11以规定的交叉轴角度(Σ)同步旋转,限定齿轮形状的鼓形状的磨石宽度方向的曲率 磨石(11)和第一对角(θ1)根据工件(W)的隆起形状设定。
