不对称盘夹及包含该不对称盘夹的主轴马达组件
摘要：
本发明提供了一种不对称盘夹及包含该盘夹的主轴马达组件。所述主轴马达组件包括主轴马达、用于存储数据并安装在所述主轴马达上的盘以及用于将盘固定到主轴马达上的盘夹。所述盘夹包括：中空部分，形成在盘夹的中部；结合部分，围绕所述中空部分的外圆周形成，并包括多个螺钉插入孔，将要结合到主轴马达的夹持紧固螺钉被插入所述多个螺钉插入孔中，按压部分，围绕所述结合部分的外圆周形成，用于按压所述盘。所述结合部分包括相对于彼此不对称的第一区域和第二区域，所述多个螺钉插入孔仅形成在第一区域中，厚度增大部分或通孔形成在第二区域的至少一部分中。
摘要（英）：

The invention provides an asymmetric disk clamp and a spindle motor assembly including the asymmetric disk clamp. The spindle motor assembly includes a spindle motor, a disk for storing data, the disk being installed on the spindle motor, and a disk clamp for fixing the disk to the spindle motor. The disk clamp includes a hollow formed in a central portion thereof, a coupling portion formed around an external circumference of the hollow and including a plurality of screw insertion holes into which clamp fastening screws to be coupled to the spindle motor are inserted, and a pressing portion formed around an external circumference of the coupling portion to press the disk. The coupling portion includes a first region and a second region that are asymmetrical with respect to each other, the plurality of screw insertion holes are formed in the first region only, and a thickness extension portion or a through hole is formed in at least a portion of the second region.
