EIXO MOTRIZ COM ELEMENTOS ACIONADORES A ELE AFIXADOS

摘要

The force-locking connection between a shaft (1) and driving elements (21) attached to it is improved or achieved via a slight plastic expansion of the shaft in that the driving elements are arranged in groups and connected by connecting sleeves (22) produced so as to be integral with the driving elements. The higher degree of elastic expansion is limited to the region of the connecting sleeves so that the driving elements themselves are largely excluded from this process. The dimensional accuracy of the finish-machined driving elements is not adversely affected. If necessary, recesses (27) may be produced to form webs (24) as a result of which the elastic deformation occurring in the inner region (23) is reduced.
