Abstract

The crankshaft of a piston engine is built up from a shaft (1) with the web and balance weight (3) and the crankpin (5) forming a single element. The crankpin (5) fits in a hole in the second web and balance weight (4) which is integral with the shaft (2). The connecting rod (6) has a big end (7) forming the outer race of the needle roller-bearing with teh needle rollers (8) running directly on the crankpin (5). A thrust washer (10) is fitted between the side face of the big end (7) and the face of the crank web (3). The innr edge of the thrust washer (10) is curved to suit the filler radius between crankpin (5) and the web (3).
