Special bearing box for counter-rotating axial flow fan

Abstract

The invention discloses a special bearing box for a counter-rotating axial flow fan. The special bearing box comprises a base, and a bottom frame is fixedly arranged in the middle of the upper end face of the base. The upper end of the bottom frame is connected with a top frame, and the bottom frame is rotationally connected with the top frame through hinges. Side connecting components and outer mounting seats are respectively arranged on the left side and the right side of the bottom frame and the top frame, and the bottom frame and the top frame are transverse provided with an optical axis segment in a penetrating mode. First bearings are arranged on the left side wall and the right side wall of the bottom frame and the top frame, and a fixed seat is arranged in the bottom frame and thetop frame. An axis hole is transversely formed in the middle of the fixed seat in a penetrating mode, and the optical axis segment is arranged in the axis hole. The left end and the right end of the optical axis segment are rotationally connected with the first bearings and are connected with principal axes. The mounting structure of the optical axis segment and the principal axes in the whole isstable. The special bearing box has the advantages of high strength, convenience in assembly and disassembly, high precision, convenience in maintenance, movement and carrying, long service life and powerful function and is worthy of promotion.

Description

technical field [0001] The invention relates to the technical field of fan devices, in particular to a special bearing box for a counter-rotating axial flow fan. Background technique [0002] The fan bearing box is a box part that supports and lubricates the bearing. Bear the axial and radial forces generated by the equipment during operation. In equipment with a rotating shaft, the shaft is generally supported by bearings for rotation, and the bearings are installed in a bearing box filled with lubricating oil. During the working process, the bearings are used to be lubricated. However, the existing bearing housings are inconvenient to install, unfavorable for maintenance, low in structural stability and spindle rotation accuracy, and short in service life. Therefore, a special bearing housing for counter-rotating axial flow fans is needed. Contents of the invention [0003] The object of the present invention is to provide a special bearing housing for counter-rotating...
