Definitions

  • crank-shaft consists of the normal main bearing journals with a crank-web at each side, the main bearing shells being carried in a stationary split disc, with a close fit in the tunnel bore. Also half discs are used, in which case the main bearing is closed with a normal bearing cap, the half disc often being underslung at that side of the tunnel bore, which is closest to the cylinders.
  • the tubular girder will be freed from tensile forces due to the combustion.
  • the reinforced edge of the tunnel also merges into the integral main bearing housing, leading the gas forces from the cylinder head through the cylinder head rods, the inner end plate and the reinforced cross walls, along the shortest way to the main bearings.
  • the joint in the main bearing housing can be flat, against circular ones in small-sized tunnel-frames.
