Abstract

A crank drive unit, such as a piston pump has a lubricating system in which the oil flows from the crosshead, by way of through bores 52, 54, 56 in the crosshead pins 58, 60, 62 and further by way of longitudinal bores 50 in connecting rods 40, 42, 44, to the crankpin bearings 10, 12, 14. Oil is fed through an inlet 82 by an oil pump 84 or from an oil tank to an outer transverse bore 80 in the drive unit housing and at the level of the crosshead, this transverse bore 80 being aligned with further transverse bores 76, 78. The transverse bores 76, 78, 80 continuously communicate with longitudinal grooves 64-74 in the crossheads, and these grooves 64- 74 communicate with the through bores 52, 54, 56 in the crosshead pins 58, 60, 62, the through bores 52, 54, 56 supplying the crankpin bearings 10, 12, 14 with oil, by way of the longitudinal bores 50 in the connecting rods 40, 42, 44. <IMAGE>
