BEARING MODULE AND ELECTRIC BLOWER HAVING THE SAME

摘要

According to one embodiment of the present invention, the bearing module comprises: a bearing supporting a shaft to be rotated; a tolerance ring coupled to the outer circumference unit of the bearing; and a ring guide having an inner space to enable the tolerance ring to be inserted and coupled to the inner space and having a coupling unit to be fixated to a fixing unit of an electric blower. The purpose of the present invention is to provide an electric blower having the bearing module, and the bearing module minimizing noise and maintaining a coupling force regardless of thermal expansion caused by a temperature change.
