摘要
A driving apparatus is used for simultaneously tensioning the jackbolts of a multi-jackbolt tensioner and includes a central drive gear mounted for rotation along a central drive gear axis. An annular array of spindles surrounds the central drive gear, each spindle independently mounted for rotation, with one spindle associated with one of the jackbolts. A socket on one spindle end is configured to receive one of the jackbolts. A spindle gear surrounds each spindle and is configured to rotate the spindle. The spindle gear is meshed with the central drive gear to be rotated by the central drive gear, wherein at least one spindle gear is offset along the central drive gear axis from at least another spindle gear. A slip clutch is positioned radially between each spindle gear and the associated spindle, wherein rotation of the jackbolts is up to a torque setting of the slip clutch during tensioning.
