| description | To provide a worm gear inspection device capable of inspecting meshing noises on a worm gear alone, and a worm gear inspection method.SOLUTION: A disclosed worm gear inspection device determines whether the worm meshing noise is acceptable or not based on the absolute value of acceleration A that is obtained by second-order differentiation in the displacement amount X in the distance between the rotation shaft of the worm relative to the rotation angle of the mating gear and the rotating shaft of the mating gear, or based on the difference Dx between the maximum value Ap1 and the minimum value Ap2 of acceleration A. With this, the meshing noise of the worm can be inspected before assembling the worm to a product; i.e., at the worm manufacturing stage (manufacturer).SELECTED DRAWING: Figure 7
【課題】ウォームギヤ単体にて当該ウォームギヤの噛み合い騒音を検査できるウォームギヤの検査装置、及びウォームギヤの検査方法を提供する。【解決手段】本発明は、相手ギヤの回転角度に対するウォームの回転軸と前記相手ギヤの回転軸との軸間距離の変位量Ｘを二階微分して得られる加速度Ａの絶対値、又は前記加速度Ａの最大値Ａｐ１と最小値Ａｐ２の差分Ｄｘにより、ウォームの噛み合い騒音の良否を判定する。このため、ウォームを製品に組み付ける前、すなわちウォームの製造段階（製造業者）において、当該ウォームの噛み合い騒音の検査を行うことができる。【選択図】図７ |
