Abstract

This invention proposes a slip ring device integrating axial flow ventilation and heat dissipation with impact-type inertial dust removal, belonging to the field of motor equipment technology. It solves the core technical defects of existing slip ring devices in actual operation, specifically including the risk of equipment overheating due to insufficient heat dissipation efficiency, the degradation of insulation performance and mechanical failure caused by dust accumulation, and the increased energy consumption and maintenance costs caused by the reliance on external power sources in traditional auxiliary systems. In this invention, the slip ring is mounted on a shaft and rotates with the shaft. The end face of the brush assembly is in contact with the conductive ring of the slip ring, conducting electricity through rotational friction. The air guide shroud has a conical cross-section and is embedded in the dust separation device, with the dust collector installed below the dust separation device. This invention organically integrates axial flow ventilation and heat dissipation with impact-type inertial dust removal technology, achieving synergistic optimization of slip ring heat dissipation and dust removal while ensuring the stable operation of the motor's transmission system.
