Abstract:
Method for the production of an assembled shaft comprising the steps of:pushing a part which has an inner bore by means of joining operations onto a shaft into a predetermined axial position and a specified circumferential position with friction contact due to fit connection, said part in a thrust direction having a lubricant groove which surrounds said inner bore and which is designed to be essentially wedge-shaped and exhibits a linear or curved slope, running in the direction of the inner wall of the bore; and introducing a lubricant into said groove when said part is slid on the shaft into the predetermined axial position, said lubricant being pulled continuously out of the groove into the inner bore of the part while said part is being joined with said shaft to reduce friction between an outer diameter of said shaft and the inner wall of said bore.
