Abstract:
1. A load cell assembly for a machine component having a bore, the load cell assembly comprising: a tubular insert including an outer sleeve insertable within the machine bore and having a tapering inner circumferential surface and an inner sleeve axially displaceable inside the outer sleeve and having a tapering outer circumferential surface complementary with the outer sleeve inner surface; a load cell connected to the inner sleeve of the tubular insert; and means for displacing the inner sleeve and the outer sleeve axially relative to each such that the sleeve outer and inner tapering surfaces slide against each other to at least partially expand the outer sleeve so as to increase a gripping force between the insert and the bore and provide a pretension to the load cell sufficient to emit signals representative of a load acting on the machine component, and wherein the outer surface of the inner sleeve and the inner surface of the outer sleeve have cooperating tapering sawtooth-formed profiles.
