    摘要： A disk mounting hub has a disk-mounting face formed at one end as a truncated conical surface of revolution symmetric about a central axis. A cylindrical inner hub member is coaxial with the hub body outside diameter and the surrounding mounting face. The inner hub member is adapted to receive a planar disk with a central opening. The mounting face is disposed at a hub face angle (n/2+/−1) relative to the central axis. Hub face angle Ω is selected so that a disk clamping force F applied to an inner disk portion surrounding the opening bends a portion of the disk interior to the hub inside diameter to conform with the conical disk-mounting face. This interior bending portion reduces or eliminates the tendency of the outer disk portion to form an excessive conning angle Φ.

    摘要： An aspect of the invention can be regarded as a method of balancing a rotary actuator for use in a rotatable head stack assembly (HSA) portion in a disk drive. The rotary actuator has a pivot axis, and the rotatable HSA portion has an installed HSA portion center-of-gravity. The method provides for deetermining a desired rotary actuator center-of-gravity location for locating the installed HSA portion center-of-gravity along the pivot axis for mitigating acceleration of the rotary actuator about the pivot axis due to external linear acceleration experienced by the disk drive during a track-follow operation. The method further provides for measuring weight distribution characteristics of the rotary actuator to determine an actual rotary actuator center-of-gravity. The method further provides for selectively modifying weight distribution characteristics of the rotary actuator to locate the actual rotary actuator center-of-gravity at the desired rotary actuator center-of-gravity location.

    摘要： An improved method for producing a final balanced and noise suppressing brake drum including a generally closed outer end, a generally axially extending cylindrical main body, and an open inner end. The closed outer end of the brake drum includes a centrally located wheel spindle opening formed therein, and a plurality of lug bolt mounting holes spaced circumferentially around the wheel spindle opening. The cylindrical main body of the brake drum is formed during a casting operation and includes a plurality of discrete raised segments formed on an outer surface thereof. Preferably, at least three raised segments are provided on an outer surface of the brake drum, and at least two of the three segments are spaced apart from one another by generally equal angles. The discrete raised segments are provided at predetermined locations on the outer surface to reduce brake noise and are selectively machined during a machining operation to produce a final balanced brake drum.

    摘要： A process for measuring an unbalance of a torque converter, in which an outer member and an inner member of the torque converter are assembled, and oil is filled into the outer member to establish a condition similar to an actual service state of the torque converter. In this condition, the two members are rotated in unison. If the rotational speed of the torque converter reaches a measuring rotational speed, a plurality of measurements are conducted with the phase of the outer and inner members being varied between each measurement through a predetermined angle, thereby correctly detecting only an unbalance due to the outer member, with an unbalance due to the inner member being canceled from the results of the measurements. Cutting a balance weight having a weight sufficient to correct the detected unbalance from a metal tape and attached said cut balance weight to an outer periphery of the outer member of the torque converter at a given position by spot-welding or adhesive-bonding.
