Process for the production of an elongate wear body

摘要

In the production of a conveyor screw (10), consisting of wear-resistant cast material, for an eccentric pump, there is already formed during its casting at its free end face a fitting surface (22) in which a counter-fitting surface (32) carried by a holder (26) can be seated with a positive fit. The eccentricity of the counter-fitting surface (32) relative to the holder axis is equal to the eccentricity of the fitting surface (22) relative to the screw axis, so that the conveyor screw (10) and holder (26) can be inserted in a processing machine in the assembled-together state such that the machine axis and the screw axis coincide. <IMAGE>
