Rotating apparatus capable of improving the shock resistance and method for manufacturing the rotating apparatus
Abstract:
A rotating apparatus includes a hub, a shaft housing portion having a center through-hole, a base plate, and a shaft with a cylindrical section housed in the through-hole. At a joint between the shaft housing portion and the hub is formed a bonding region for bonding the shaft housing portion and the hub by a hardening resin, and a narrow-gap region more toward the base plate than the bonding region. A gap between the shaft housing portion and the hub in the narrow-gap region is narrower than a gap between the shaft housing portion and the hub in the bonding region. The hub includes a fourth circumferential recessed portion recessed in the axial direction and a lower circumferential raised portion projecting in the axial direction on a radially inner side of the fourth circumferential recessed portion. The narrow-gap region is located inside the lower circumferential raised portion.
Abstract(Chinese):

旋转装置包括轮毂，具有中心通孔的轴容纳部分，基板和具有容纳在通孔中的圆柱形部分的轴。 在轴壳部和轮毂之间的接合处形成有用于通过硬化树脂将轴容纳部和轮毂接合的接合区域，以及比接合区域更靠近底板的窄间隙区域。 狭缝间隙区域的轴收纳部与轮毂之间的间隙比接合区域的轴收纳部与轮毂之间的间隙窄。 毂包括沿轴向凹陷的第四周向凹部和在第四圆周凹部的径向内侧沿轴向突出的下周向凸起部。 窄间隙区域位于下周向隆起部分的内部。
