| Abstract | Tolerance-ring (T-ring) installation is one of the assembly processes used to assemble a bearing cartridge that consists of one or two miniature ball bearings, a center shaft and a bearing sleeve to the bore of a hard disk drive (HDD) actuator arm. This process is widely used due to its cost effectiveness, repeatability of assembly, ease of rework, short cycle time and fulfillment of a resonance performance design requirement. In this paper, the finite element (FE) model of a T-ring installation process is proposed. The FE computational result of push-in force is compared to that from experiment, and it is found to be acceptable. It is also found that the solid elements provide better computational results than the shells. Then this model is further used to determine the main contributor to push-in force. It is found that the bearing sleeve parallelism has significant impact on the process but it is somewhat unaffected by the change in the lead-in chamfer. |
