Title: RECIPROCATING PISTON MACHINE, IN PARTICULAR ONE-, TWO-, OR THREE-STAGE PISTON COMPRESSOR FOR A COMPRESSED AIR SUPPLY SYSTEM OF A VEHICLE
Abstract:
The invention relates to a reciprocating piston machine, in particular a one-, two-, or multi-stage piston compressor (400) or a one-, two-, or multi-cylinder compressor, having: at least one cylinder (410, 420) and at least one piston (K1, K2) each assigned to a cylinder (410, 420), wherein, during operation, the piston (K1, K2) is deflected along a radially oriented cylinder axis (Z) in a cylinder displacement space (411, 421) of the cylinder (410, 420); a crankshaft (430) that can be driven during operation and has a crankshaft journal (432), which is arranged eccentrically in relation to a shaft axis (E) of the crankshaft, and a drive shaft coupling (431), which is designed for coupling a drive shaft (501) for driving the crankshaft (430); at least one connecting rod (P1, P2), each designed to deflect the at least one piston (K1, K2) and extending along a connecting rod axis (Pa, Pb), which can be moved by means of the crankshaft journal (432), wherein the crankshaft journal (432) and/or the drive shaft coupling (431) is/are oriented along an axially aligned shaft axis (E) which extends at right angles to the radially oriented cylinder axis (Z). The connecting rod axis (Pa) of the connecting rod (P1) is located in a position in which at least one connecting rod bearing (L1, L2) is braced with respect to the crankshaft journal (432) by a predetermined force (Fk) acting on the at least one connecting rod bearing (L1, L2) along the direction of the shaft axis (E), in particular in such a way that the bearing play of the at least one connecting rod bearing (L1, L2) is reduced. The connecting rod axis (Pa) of the connecting rod (P1) is moved into the position in which a force acting along the direction of the shaft axis (E) is applied to the at least one connecting rod bearing (L1), until a predetermined opposing force is reached.
