Ring Blower of air cooler structure bearing for bearing

摘要

The present invention relates to a bearing air cooling structure of a ring blower, and more specifically, heat generated in a bearing supporting a motor shaft in a ring blower is primarily cooled with air sucked from the outside and discharged secondly to separate bearing cooling. The present invention relates to a bearing air cooling structure of a ring blower, which is not only provided with a device, but also has a simple structure and can extend the life of the bearing.;That is, a bearing that supports the shaft of the motor is installed on both sides of the impeller and the impeller is mounted on the motor of the motor and the shaft of the motor so as to discharge the outside air to the compressed high-pressure and high-speed air by suction In the upper and lower casing provided in the inside and the ring blower formed in the upper and lower casings, the outer flow passage formed outside the lower casing and the air flowing from the outer flow passage flow into the inner flow passage. It characterized in that the bearing is air-cooled.
