Abstract
The invention relates to the technical field of design and manufacturing of a high-speed transmission shaft of a horizontal-type axial flow fan special for a cooling tower, and in particular relates to an anti-flying transmission shaft. The shaft comprises a transmission shaft body, a flange one, a flange two, a motor end half coupling, a reducer end half coupling, a transmission shaft half coupling and an elastic membrane; and the flange one and the flange two are designed into an integral with the transmission shaft coupling. According to the invention, under the condition of the damages of a linked bolt and a membrane, the transmission assembly can be ensured to be positioned on the original position tightly without generating falling and fly phenomenon. The shaft provided by the invention reliablely ensures that the safety running all the year round for a cooling tower fan is realized, the damages of important components caused by flying shaft accidents are eradicated thoroughly, and the overhauling and maintaining are reliable and convenient.
Description
Technical field
The present invention relates to blower fan of cooling tower transmission shaft technical field, especially a kind of anti-transmission shaft that flies.
Background technique
The Placement of existing transmission shaft is in blower fan high speed heavy load running all the year round, and attachment bolt and diaphragm between the two pairs of coupling are subjected to load impacting and mechanical wear inevitably.To cause transmission shaft integral body to come off or the accident that flies out if fracture takes place, and attachment bolt, diaphragm be difficult for obtaining repairing after impaired in short-term, bring inconvenience for equipment operation management personnel's safety operation.
Summary of the invention
In order to overcome existing transmission shaft and the low deficiency of blower fan connection safety, the invention provides a kind of anti-transmission shaft that flies.
The technical solution adopted for the present invention to solve the technical problems is: a kind ofly anti-fly transmission shaft, comprise the transmission shaft body, described transmission shaft body two ends are respectively equipped with flange one and flange two, and described flange one and flange two are the integrated design with the transmission shaft body.
The invention has the beneficial effects as follows: under the situation of propeller shaft couplings bolt and diaphragm damage, still can reliably be connected on the blower fan transmission system, reduce blower fan day-to-day operation accident to greatest extent, guarantee blower fan safe operation all the year round; In the maintenance easily of the impaired back of transmission shaft, improved working efficiency.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the schematic representation of the embodiment of the invention.
Among the figure 1, the transmission shaft body, 2, flange one, 3, flange two, 4, motor half-coupling, 5, the speed reducer half-coupling, 6, the transmission shaft half-coupling, 7, diaphragm.
Embodiment
As Fig. 1 is structural representation of the present invention, a kind ofly anti-flies transmission shaft, comprises transmission shaft body 1, and described transmission shaft body 1 two ends are respectively equipped with flange 1 and flange 23, and described flange 1 and flange 23 are the integrated design with transmission shaft body 1.
As shown in Figure 2, an end of transmission shaft body 1 connects transmission shaft half-coupling 6 and motor half-coupling 4 successively, and the other end connects transmission shaft half-coupling 6 and speed reducer half-coupling 5 successively.Be respectively equipped with diaphragm 7 between described transmission shaft half-coupling 6 and the motor half-coupling 4 and between transmission shaft half-coupling 6 and the speed reducer half-coupling 5.When blower fan transmission system operation catastrophic failure, still can be connected with flange 23 by flange 1, and then prevent coming off and flying out of transmission shaft with transmission shaft.
Claims (1)
1. prevent flying transmission shaft for one kind, comprise transmission shaft body (1), it is characterized in that described transmission shaft body (1) two ends are respectively equipped with flange one (2) and flange two (3), described flange one (2) and flange two (3) are the integrated design with transmission shaft body (1).
