Smart cold circulation system for heat radiation of bearing pedestal

Abstract

The invention discloses a smart cold circulation system for heat radiation of a bearing pedestal. The smart cold circulation system comprises a bearing pedestal body and a water cooling cavity, wherein the water cooling cavity is in a M-shape with the opening facing towards the left side, a cooling water tank is arranged on the outer wall of the bearing pedestal body, and a cooling water circulation outlet pipe is connected to the water outlet of the water tank. A first water pump and a first hydraulic pressure sensor are connected to the cooling water circulation outlet pipe, and a cooling water circulation inlet pipe is connected to the water inlet of the water tank. A second water pump and second hydraulic pressure sensor are connected to the cooling water circulation inlet pipe, a control box is arranged on the outer wall of the cooling water tank, and a controller is arranged in the control box. The controller comprises an AVR single-chip microcomputer, a power supply module, a crystal oscillator circuit module, a reset circuit module, a flash data storage circuit module, a signal conditioning circuit module, a key operation circuit module, a water temperature sensor, a plurality of semiconductor refrigeration sheets, a liquid crystal display screen, a first water pump driver, a second water pump driver and a switch circuit. The smart cold circulation system has no cooling blind corners, cools uniformly, and is highly reliable.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation of bearing seats, and in particular relates to an intelligent cold cycle system for heat dissipation of bearing seats. Background technique [0002] The bearing is an important supporting element of the rotating spindle, and the bearing seat is used to fix and support the bearing and bear the force and torque on the shaft. Since the rolling body of the bearing generates heat when it rotates, the heat must be transmitted through the bearing seat in time, so the bearing seat needs to play a role in cooling the bearing, especially in some high-temperature environments or high-speed rotating spindles, the bearing heat is more serious , good heat dissipation is required to ensure that the temperature of the bearing is within an allowable range, prolong the life of the bearing, and ensure the normal operation of the bearing. If the bearing is not cooled in time, the wear of the bearing will be...

AI Technical Summary

Problems solved by technology

If the bearing is not cooled in time, the wear of the bearing will be aggravated, and in severe cases, the expansion of the bearing will cause the bearing to be stuck and fail

Traditional bearing cooling methods include natural cooling, air cooling, water cooling, and oil cooling. Natural cooling and air cooling have poor cooling effects and are often used in environments with low heat generation. Complex and high maintenance cost, it is used in some high-end products, while the water-cooling method has a simple structure and good cooling effect, and has been widely used

However, most of the water cooling methods in the prior art are to directly install a water cooling cavity on the structure of the bearing. The cooling water only circulates once in the water cooling cavity and then comes out from the drain port, which has the defects of uneven cooling and poor cooling effect. and deficiency
