Abstract

The invention relates to a direct driving type pressure expanding guide vane adjusting device. The direct driving type pressure expanding guide vane adjusting device comprises guide vanes, rotation arms, a rotary plate and idler wheels. The rotary arms are fixedly connected with the shaft necks of the guide vanes through first keys respectively, one end of each connecting rod is connected with the corresponding rotation arm through first hinge pins, and the other end of each connecting rod is connected with the corresponding shaft hole through second hinge pins, wherein the shaft holes are evenly distributed in the rotary plate through second hinge pins respectively. The shaft necks of the idler wheels are installed in second shaft holes evenly distributed in a gear box flange respectively, and the internal diameter of the rotary plate is tangent with each idler wheel. The direct driving type pressure expanding guide vane adjusting device is characterized by further comprising a motor, the number of the guide vanes is nine, the shaft necks of the guide vanes are installed in first shaft holes evenly distributed in the gear box flange, and the motor is connected with a rotating shaft of a driving guide vane. The direct driving type pressure expanding guide vane adjusting device is simple, compact and reasonable in structure, low in manufacturing cost and suitable for being used on high-speed centrifugal fans of all standards. All guide vanes can be synchronously adjusted, and synchronous adjustment is guaranteed.

Description

technical field [0001] The invention relates to a direct-drive diffuser guide vane adjustment device, in particular to a mechanical device for synchronously adjusting the outlet guide vane angle on a high-speed centrifugal fan, which belongs to the technical field of mechanical structures. Background technique [0002] In the existing technology, the high-speed centrifugal fan can maintain high efficiency when the flow rate is changed by adjusting the outlet guide vane. The adjustment of the guide vane is generally realized by gear and sprocket transmission, which has a complex structure and high manufacturing cost. . Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages, thereby providing a direct-drive diffuser guide vane adjustment device with simple structure and low cost. [0004] According to the technical solution provided by the present invention, a direct-drive diffuser guide vane adjustment device includes ...
