An improved basket assembly and method of making same of the type designed for use in a sugar centrifuge that includes an annular mounting flange containing an upwardly-flared frustoconical seat and an open-bottomed conical element adapted to mate in assembled relation with the aforementioned frustoconical flange seat. The apparatus is characterized by shaping the opposed surfaces at the lower end of the cone and base of the seat so as to cooperate with one another in assembled relation to define an upwardly-opening and inwardly-flared continuous annular groove for the reception of a weld. The apparatus also includes a circumferentially-spaced series of apertures in the wall of the cone opening onto the conical surface of the seat when assembled to receive a corresponding number of plug welds. The method of assembling the cone and flange assembly includes the unique feature of taking advantage of the shrinking action of the continuous annular weld to draw the cone down into its seat thus defining a shrink fit therebetween and maintaining the relationship thus established upon relaxation of the external forces holding the parts in assembled relation by placing distortion-free plug welds within the cone apertures.
The combination in a basket assembly for use in a sugar centrifuge of a hollow upwradly-flared open-bottomed frustoconical member, an annular mounting flange for said frustoconical member having a frustoconical seat shaped to receive same and a first weld joining said frustoconical member and its mounting flange together in assembled relation, said frustoconical member and flange having opposed weld-receiving surfaces spaced apart to leave a portion of said seat exposed therebetween in assembled relation, said weld-receiving surfaces cooperating with one another and said exposed portion of the seat to define an inwardly-opening continuous annular groove for the reception of the weld, and said first weld when in place within the groove being effective to draw the frustoconical member into its seat so as to maintain a shrink-fit relation between it and its mounting flange.
The method for fastening the upwardly-flared open-bottomed frustoconical element of a sugar centrifuge basket assembly within the frustoconical seat shaped to receive same in the mounting flange therefor which comprises the steps of:
