Tray assembly for spindle motor with aerodynamic bearing

摘要

A tray assembly for a spindle motor includes a tray and an aerodynamic rotational shaft. The tray includes an engaging hole in a center thereof. The aerodynamic rotational shaft includes an outer circumference with a smooth surface. An end of the aerodynamic rotational shaft is engaged in the engaging hole of the tray, with the outer circumference of the end of the aerodynamic rotational shaft engaged with an inner circumference of the engaging hole of the tray by forcibly fitting, allowing precise control and adjustment of an engaging relationship between the aerodynamic rotational shaft and the tray.
