A power transmitting mechanism for reciprocating engines or pumps connecting the piston rods of a plurality of cylinders with a slant on a main shaft, the cylinder axes being parallel with the main shaft. The connection is provided by means of claw-shaped crossheads gripping the slant, one crosshead for each piston rod. Between the crosshead and the slant a main thrust block and a back thrust block are placed eccentrically. The crosshead may pivot around its longitudinal axis and is provided with two thrust blocks of the Michell type, the centres of these two blocks being arranged in a plane perpendicular to the longitudinal axis of the crosshead and in the middle of the gap of the crosshead. Said two thrust blocks are further adapted to slide on the cylindrical edge surface of the slant, so that, in common or individually together with a relatively short external bearing supporting surface of the crosshead, they absorb the transverse components of the rotating transverse force vector, the bearing supporting surface co-operating with an axially extending semicircular sliding guide of the engine or pump housing. |
