The present invention provides for a flexural pivot that can be fitted within
a cavity of an actuator. The pivot includes a first member that can be coupled
to the wall defining the cavity and a second member that can be mounted to the
disc drive housing component of the disc drive. At least two leaves join external
surfaces of the first member to the second member.
The present invention offers a flexural pivot that can be easily incorporated
with rotary actuators traditionally designed for use with a ball bearing pivot
cartridge. In addition, it avoids the difficulties encountered by conventional
designs when trying to assemble intersecting flat springs within a cylindrical
sleeve. Furthermore, in comparison with conventional flexural pivots that are located
outside the actuator body, the present invention provides a compact pivot that
can be mounted substantially in a cavity of the actuator body such that the center
of rotation of the actuator is located nearer the center of mass.
