摘要
A tensioning apparatus is provided that is arranged to simultaneously tension a plurality of jackbolts of a multi jackbolt tensioner (MJT). The tensioning apparatus has a housing that is arranged for receiving a drive gear from a drive unit. The tensioning apparatus includes one or more planetary gears that are retained within the housing and which mesh with the drive gear in use. A ring gear encircles the one or more planetary gears and meshes with them. A plurality of spindle gears is retained in the housing. Each of the spindle gears has a spindle for coupling to a respective one of the jackbolts. The spindle gears are located around the ring gear and mesh with teeth on an outside of the ring gear. In use the drive gear rotates the one or more planetary gears to thereby rotate the spindle gears via the ring gear to thereby tension the jackbolts. The tensioning apparatus may be made compact by overlapping gear disks of the spindle gears and acts as a torque multiplier between the planetary gears and the spindle gears.
