Internal cooling method for shaft core of rotating structure

Abstract

The invention discloses an internal cooling method for a shaft core of a rotating structure. The internal cooling method comprises the following steps of S1, arranging a cooling liquid channel, namely arranging the cooling liquid channel inside the shaft core of the rotating structure, and correspondingly forming a liquid inlet and a liquid outlet in the cooling liquid channel; S2, installing a rotating assembly; S3, connecting a cooling water supply device; S4, starting the cooling water supply device; and S5, enabling the cooling liquid in the shaft core of the rotating structure to flow back to the cooling water supply device through the liquid outlet for heat dissipation for repeated use. According to the internal cooling method, the shaft core is used for cooling, the face generating heat can be directly used for conducting heat to the cooling liquid to the maximum extent, the heat is conducted to the cooling liquid along the metal material, and the cooling liquid directly flows back to a radiator through the shaft core for heat dissipation so as to be repeatedly used, the nternal cooling method is particularly suitable for a structure with the internal heat canno be dissipated or difficult to dissipate, and the heat conductivity of the metal material is high, so that the heat dissipation is more facilitated.

Description

technical field [0001] The invention belongs to the field of internal cooling of the shaft core, and more specifically relates to an internal cooling method of the shaft core for a rotating structure. Background technique [0002] At present, common rotating structures include mechanical equipment such as machine tool shafts and augers. For machine tool shafts, the existing machining cooling methods mainly use coolant spray cooling, which can only cool the machined parts and cannot cool the shaft parts. For the auger, most of them are external cooling, the cooling efficiency is low and the time delay is high. Therefore, we propose an internal cooling method for the shaft core for the rotating structure Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a method for internal cooling of the shaft core used in the rotating structure. This method has high direct cooling efficiency and can ensure th...
