Centrifugal plant for producing bimetallic sleeves

摘要

A plant for producing bimetallic sleeves by pouring molten so called babbitt metal into the space of a sleeve being rotated. The plant comprises a head stock and a tail stock mounted on a bed, the tail stock being slidable along the axis of the sleeve being babbitted, each mounting means for centering and clamping the sleeve that is poured in between them with the help of cones set up on the head and the tail stocks.The tail stock mounts a pouring device wherein the babbitt metal to be poured into the sleeve is delivered by a batcher. The pouring device includes a feed funnel adapted to receive the molten babbitt from the batcher, a pipe enclosed in the axis of the sleeve, a connecting pipe supplying the molten babbitt from the feed funnel into the pipe, and a chute onto which the molten babbitt is delivered from the pipe through an opening provided therein. The chute is inclined to the direction of rotation of the sleeve so that the babbitt is fed directly to the internal wall of the rotating sleeve along its entire length and flows off in the direction of its rotation. The sleeve being babbitted is cooled by sprayers mounted along its periphery so that the entire external surface of the sleeve is simultaneously exposed to the effect of the coolant.
