Abstract
A limit stop for defining the range of motion of a disc drive actuator. The limit stop is formed from a single piece of material. It includes a cylindrical contact surface on the distal end of a cylindrical cantilevered beam. The beam is connected to a central mounting shaft by a radially extending bridging element. The compliance of the stop is determined by the material selection and control of certain dimensions.
Claims1
A limit stop for limiting the range of motion of an actuator in a disc drive, the actuator including a moving portion which further includes a contact feature for contacting the limit stop, the limit stop comprising
- one continuous piece of material forming:
- a central shaft, the central shaft including mounting means for attaching the limit stop within the disc drive;
- a substantially non-compliant bridging portion encircling the central shaft and extending radially therefrom;
- a cylindrical compliance portion forming a continuous cantilever beam, the cylindrical compliance portion having a first proximal end integral to the outer extent of the bridging portion and a second distal end, the cylindrical compliance portion being coaxial with the central shaft and extending axially from the outer extreme of the bridging portion;
- and
- the outer surface of the distal end of the cylindrical compliance portion forming a cylindrical contact surface for engagement with the contact feature of the actuator, the cylindrical contact surface being coaxial with the central shaft and the cylindrical compliance portion.
