The abstract relates to Fig. 1 A steam engine, which comprises a crankcase frame (1) arranged so as to rest on a foundation, a steam cylinder (25) supported by the crankcase frame, a cylinder bore (28) in the steam cylinder, a reciprocating piston (45) in the cylinder bore (1), a connecting rod (50), connected at one end with the piston by means of a piston rod (46), steam values on the cylinder, a crankshaft (56) with crank webs (57, 65) supporting a crank pin (63), for the other end of the connecting rod a crank pin (63), and in the crankcase a plurality of crankshaft bearings (8) allowing rotation of the crankshaft. The crankcase frame's (1) principal supporting members consist of two horizontally lying beams (2), arranged so as to support between themselves the crank bearings (8) for the crankshaft (56), from each of the lying beams vertically standing beams (12) forming columns for supporting a plate with a hole (14) for the cylinder (25) as well as beams (15) extending between the vertically standing beams for bracing the standing beams. The plate is arranged so as to support in its hole (14) the cylinder (25), formed as a unit, which by means of a guide extends down into the hole (14). |
