AI Technical Summary

Technical Problem

Conventional rotary tables in metalworking machines face issues with heat generation during high-speed operation, leading to impaired functioning of internal mechanisms and potential component failure due to friction, and existing cooling solutions are inefficient or require additional components that compromise lubrication functions.

Method used

A rotary table with an integrated cooling circuit featuring a mandrel with inlet and outlet sections, a cooling chamber, and return sections, allowing for effective heat dissipation of sealing elements, brakes, and bearings through a continuous flow path, eliminating the need for additional cooling components and maximizing space.

Benefits of technology

The cooling circuit effectively dissipates heat generated during high-speed operation, ensuring stable performance and extended service life by suppressing temperature rise, thereby improving operational efficiency and maintaining proper function during prolonged high-load conditions.

Abstract

A rotary table equipped with a cooling circuit, consisting of a mandrel formed in the axial direction with several inlet sections, several first flow sections each continuously connected to an inlet section or designed around the axial direction, an outlet section continuously connected to all individual first flow sections, and a first return section parallel to the axial direction, both ends of which are each designed as a first return inlet and a first return outlet, and a rotary table rigidly coupled to the mandrel and provided with a second flow section continuously connected to the outlet section, a cooling chamber continuously connected to the second flow section, and a second return section continuously connected between the cooling chamber and the first return inlet.With this arrangement, the heat generated by the sealing elements, the brake and the bearings during the rapid rotation of the rotary table is dissipated with high efficiency to ensure proper operation.
