摘要： @ A method of and means for controlling a clearance in a machine having a rotary element is disclosed. The embodiment depicted comprises a pair of coacting rotors, in a rotary compressor, having interengaging lobes and grooves, the rotors being journalled in intersecting bores in a housing. The circumferential surfaces, and end walls of the bores are polymer-layered, and the rotors carry abrasive to machine the polymer to define an optimum clearance for rotor rotation within the bores, and in coaction together. Each rotor is polymer-coated and abrasive particles are borne in the polymer on the outer edges of the lobes and in discrete radial patterns on the rotor sides. The method defines the polymer-coating and abrasive particles-deposition steps.
