Abstract: A method of swaging a head gimbal assembly (HGA) to an actuator arm comprises positioning a tubular element on the HGA adjacent a hole in the actuator arm; restraining the subassembly; providing a rod formed from a shape memory alloy (SMA), the SMA having a martensitic phase at a low temperature and an austenitic phase above a phase transition temperature that is higher than the low temperature, the rod having an initial diameter that is smaller than diameters of the tubular element and the hole; extending the rod through the tubular element and hole; heating the rod above the phase transition temperature such that the rod expands to a second diameter that is greater than the initial diameter to plastically deform the HGA and swage together the HGA and actuator arm to form an assembly; cooling the rod and removing the rod from the assembly such that the rod returns to the initial diameter.

Abstract: A combination mounting ring of resilient material, for connecting a shaft within a bore of a housing, has a hollow cylindrical part having radially extending projections. This part is for locating between the outer surface of the shaft and the inner surface of the bore, the radially extending projections being under compression and thus securing the shaft within the bore. The combination mounting ring further has an axial spring element extending radially inward from the cylindrical part and having two portions at different axial positions. The axial spring element is for locating between the shaft and a body axially displaced from the shaft, and serves to minimize axial movement of the shaft within the bore of the housing. The axial spring element may either be an annular part or a tab extending from an axial edge of the cylindrical part.

Abstract: A mounting assembly comprising mating inner and outer components (36, 38) mounted together using a tolerance (20) is disclosed. The tolerance ring (20) has radially extending projections (28) that are configured to cause the tolerance ring (20) to operate into the plastic phase of its compression force/retention force characteristic. This can be achieved by using softer projections than those found in conventional tolerance rings. The force required to mount the tolerance ring and a range of retention forces exhibited by it for a given variance in sizes of mating components is thereby stabilized.

Further compressive, tensile, flexural or torsional forces will be developed within other parts of the structure and additional member as a result of the shim expansion depending on the particular arrangement.
