| titleOfInvention | Expandable hub locking assembly |
| abstract | The present disclosure relates to an expandable hub assembly constructed to provide a locking connection between two members such as a shaft and the smooth bore of a pulley. The expandable hub assembly includes inner and outer annular hub parts which have slidably engaging frustoconical surfaces. The hub parts each have axial slits to accommodate radial contraction and expansion. Three intermediate members interconnect the two hub parts. Each intermediate member has a coarse screw thread portion which engages a threaded hole in the inner hub part and a fine screw thread portion that engages a threaded hole in the outer part. Rotation of the intermediate members will produce relative axial displacement between the two hub parts as a result of the differential in the pitch of the screw threads. This axial movement, in combination with the sliding engagement of the frustoconical surfaces, will produce radial contraction and expansion of the inner and outer hub parts into gripping engagement with the shaft and the bore of the pulley. The radial movement of the hub parts will also cause the intermediate threaded members to be distorted and this deformation will produce forces that resist accidental disassembly of the expandable hub that might otherwise result from normal machinery vibration. |
