Shield restricting axial movement

摘要

In one example, an FDB motor having a shield member is provided. In one example, the method includes disposing a first member and a second member for relative rotation about an axis of rotation. An annular shield member is attached to the first member, the shield member disposed adjacent a fluid reservoir for containing a bearing fluid. The reservoir is filled through an aperture (e.g., a fill hole) in the shield member. Thereafter, the aperture is at least partially sealed. The aperture may be hermetically sealed via one or more laser pulses. In other examples, a two piece shield is provided for shielding a reservoir without a fill hole.

1. An apparatus comprising:
a first member and a second member; and a shield member coupled to a rotatable sleeve, wherein an edge of said shield member is configured to restrict axial movement of said first member with respect to said second member, said shield member comprises an aperture for receiving fluid, and said aperture is further configured to be sealed subsequent to receiving said fluid, and further defines a fluid reservoir configured to store said fluid.
