- Abstract
Grinding is a prevalent metal processing method extensively employed in industrial production. However, the high temperatures generated during the grinding process can elevate the temperature of the grinding motorized spindle, subsequently impacting its performance and lifespan. Therefore, the design and research of the grinding motorized spindle cooling system become particularly important. In order to study the thermal characteristics of the grinding motorized spindle, this paper studies the two heating paths of the grinding motorized spindle based on the heat source, including the heat loss of the motor and the friction heat of the bearing, and establishes a fluid heat transfer model. Through cooling system design and thermal characteristic simulation analysis, the U-shaped cooling grinding motorized spindle is determined. The experiment found that the spindle temperature rise results are consistent with the numerical simulation results. Although the vibration amplitude will increase with the increase of the rotational speed, it will always remain within a stable range, which verifies the rationality of the cooling system design and provides ideas and methods for the design and optimization of the cooling system of the grinding motorized spindle in the future.
