ROTARY SHAFT SEALING DEVICE FOR CENTRIFUGAL BLOWER

摘要

PROBLEM TO BE SOLVED: To provide a rotary shaft sealing device for centrifugal blower capable of facilitating the assembling without receiving the influence of the vibration of a casing. SOLUTION: A static part of a rotary shaft sealing device 10a provided between a casing 2 and a rotary shaft 3 of a centrifugal blower is held by a bearing part 6 of the rotary shaft 3, and a displacement between the static part and a rotary part is eliminated so as to facilitate the assembling of the rotary shaft sealing device 10a. A clearance between the static part of the rotary shaft sealing device 10a and the casing 2 is sealed by a flexible plate 43 so as to prevent the transmission of the vibration of the casing 2 to the rotary shaft sealing device 10a.
