Motor or compressor unit with three parallel crankshafts - has crankpins intercoupled by triangular yoke giving synchronised rotation in same direction

摘要

The crankshaft arrangement comprises two parallel shafts (2, 3) connected to rotate synchronously in the same direction. a yoke(16) connects three crank pins(14, 15, 17) of which two(14, 15) belong to the crank shafts(2, 3). The third pin(17) is part of a third crank shaft(18) parallel to the first two and at a distance from the plane through these two. The crank pins connected by the yoke may each be arranged between adjacent crank pins on their respective crank shafts or may be arranged at the ends of their respective shafts.
