Abstract
The utility model relates to coupling field, provides a kind of coupling shield, and this coupling shield comprises left half guard shield, right half guard shield, left half guard shield are connected with right half guard shield Spielpassung; There is two seals groove the cylndrical surface coordinated with right half guard shield at left half guard shield, in seal groove, be equipped with seal ring.The coupling of rotation and the external world separate by this coupling shield, avoid security incident to occur; Sealing is formed to the lubricant oil in unit bearing housing, prevents mist of oil from leaking outside; The utility model structure is simple, and low cost of manufacture, achieves the protection to coupling, improves the safety and stability of coupling work, effectively facilitates the raising of manufacturing efficiency.
Description
Technical field
The utility model relates to coupling field, refers more particularly to a kind of coupling shield.
Background technique
The Large centrifugal compressors of current use is open connection, and namely compressor and driving machine are two cylinder bodies separated.When driving machine drives compressor operation, then to be connected by coupling, but coupling is often subject to the impact of peripheral dust, humidity or dry environment, the working life, performance, Security etc. of coupling are subject to very large harmful effect, thus have influence on the normal operation of whole unit, reduce manufacturing efficiency, add cost of production.
Model utility content
The utility model, for above-mentioned defect, provides a kind of coupling shield, and this coupling shield comprises left half guard shield, right half guard shield, left half guard shield are connected with right half guard shield Spielpassung; There is two seals groove the cylndrical surface coordinated with right half guard shield at left half guard shield, in seal groove, be equipped with seal ring.
Further, the both ends of the surface of cylndrical surface that seal groove coordinates from left half guard shield with right half guard shield are 20mm ~ 30mm.
Further, half guard shield comprises first guard shield A, second guard shield B, and first guard shield A is connected with second guard shield B bolt.
Further, the upper lower flange that first guard shield A is connected with next guard shield B is also equipped with alignment pin A.
Further, right half guard shield comprises first guard shield C, second guard shield D, and first guard shield C is connected with second guard shield D bolt.
Further, the upper lower flange that first guard shield C is connected with second guard shield D is also equipped with alignment pin B.
Further, the inner chamber of right half guard shield also has stiffening ring.
Compared with prior art, owing to have employed left half guard shield, right half guard shield, the coupling of rotation and the external world separate the utility model by this coupling shield, avoid security incident to occur; Have employed seal ring and sealing is formed to the lubricant oil in unit bearing housing, prevent mist of oil from leaking outside; This cover assembly connects down through bolt, and adopts positioning dowel to locate, and guarantees the coaxality of guard shield and coupling when each dismounting, effectively prevent coupling and guard shield and produces and rub, further increase the security of operation of coupling.

Fig. 1 is that master of the present utility model looks partial schematic sectional view;
Fig. 2 is the utility model I close-up schematic view;
Fig. 3 is left half guard shield of the present utility model, right half hood member decomposing schematic representation;
Description of symbols in figure: 1 left half guard shield, 2 right half guard shields, 3 seal grooves, 4 seal rings, 5 first guard shield A, 6 second guard shield B, 7 alignment pin A, 8 first guard shield C, 9 second guard shield D, 10 alignment pin B, 11 stiffening rings.
Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model is described in detail, so that those skilled in the art better understand and implement this programme.
As shown in Figure 1, this coupling shield comprises left half guard shield 1, right half guard shield 2, left half guard shield 1 be connected with right half guard shield 2 Spielpassung; As shown in Figure 2, there is two seals groove 3 cylndrical surface that left half guard shield 1 coordinates with right half guard shield 2, is equipped with seal ring 4 in seal groove 3; The program effectively realizes coupling to be isolated from the outside, and realizes forming sealing to the lubricant oil in unit bearing housing, prevents mist of oil from leaking outside.
More specifically, as shown in Figure 3, left half guard shield 1 comprises first guard shield A5, second guard shield B6, and first guard shield A5 is connected with second guard shield B6 bolt; The upper lower flange that first guard shield A5 is connected with next guard shield B6 also has alignment pin A7; Ensure that the coaxality of guard shield and coupling, effectively prevent coupling and left half guard shield 1 and produce and rub, further increase the security of operation of coupling.Right half guard shield 2 comprises first guard shield C8, second guard shield D9, and first guard shield C8 is connected with second guard shield D9 bolt; The upper lower flange that first guard shield C8 is connected with second guard shield D9 also has alignment pin B10.Ensure that the coaxality of guard shield and coupling, effectively prevent coupling and right half guard shield 2 and produce and rub, further increase the security of operation of coupling.The inner chamber of right half guard shield 2 also has stiffening ring 11, improves the intensity of right half guard shield 2, improves coupling shield safety and stability further.
The utility model structure is simple, and low cost of manufacture, achieves the protection to coupling, improves the safety and stability of coupling work, effectively facilitates the raising of manufacturing efficiency.
