Description

Technical Field

[0001] This utility model relates to the field of fan transmission box technology, and in particular to a fan transmission box device. Background Technology

[0002] When the main shaft of a centrifugal fan is driven, it is lubricated and supported by a transmission box. However, when the existing transmission box is used for periodic bearing replacement, the fan impeller on the main shaft needs to be disassembled before the main shaft can be removed from the transmission box and the bearing on the main shaft can be replaced. This is not only time-consuming, but also difficult to disassemble and assemble.

[0003] A centrifugal fan transmission box, disclosed in CN218000179U, includes a fan bearing housing and a main shaft. The fan bearing housing has a first bearing support and a second bearing support respectively installed at its two connecting ends. A first bearing and a second bearing are inserted and installed in the middle of the main shaft, with the outer diameter of the first bearing being larger than that of the second bearing. This transmission box is integrally cast, and its internal cavity design features a larger front bearing and a smaller rear bearing, with a large space between the two bearings. This allows for the storage of more lubricating oil, ensuring sufficient lubrication of both bearings and significantly extending their service life. Furthermore, the installation method of a larger front bearing and a smaller rear bearing offers significant advantages compared to traditional transmission boxes. During on-site maintenance, it avoids disassembling the fan impeller and allows for direct replacement of the front and rear bearings. This avoids situations where the shaft and impeller cannot be disassembled due to long-term use of the fan, necessitating replacement of the main shaft and reducing on-site maintenance costs.

[0004] The above technical solution can quickly repair the corresponding components, but it cannot quickly repair the steering mechanism used for internal transmission, and it cannot guarantee the overall strength, so it needs to be improved. Utility Model Content
