Abstract
The utility model discloses an impeller assembly and spindle locating structure for a transmission centrifugal fan. The locating structure comprises a spindle and an impeller assembly shaft disk, a limit step is arranged on the spindle, the impeller assembly shaft disk is sleeved on the spindle on one side of the limit step, a connection disk is sleeved on the other side of the limit step, and the impeller assembly shaft disk is detachably and fixedly connected with the connection disk. According to the impeller assembly and spindle locating structure for the transmission centrifugal fan, the spindle and the impeller assembly shaft disk are fixed through the connection disk, axial sliding of the impeller assembly on the spindle is avoided, when the impeller assembly is disassembled, a bolt only needs to be screwed off, a locating key exits from the right side, and accurate locating of the spindle and the impeller assembly is achieved. Meanwhile the impeller assembly and spindle locating structure is stable in structure and convenient to assemble and disassemble.
Description
Technical field
The utility model relates to a kind of position structure, and concrete is the position structure of a kind of transmission centrifugal blower fan blade wheel group and main shaft.
Background technique
The main shaft of existing centrifugal blower rotor set and the location of impeller sets adopt the standard round nut screwing clamping to locate usually, and be high but the accuracy of screw machining of main shaft and round nut requires, the fabricating cost height; Simultaneously in installation process, all need bigger screwing force and loosen moving measure, and when dismounting, need knock the round nut outside when withdrawing from round nut repeatedly, be easy to make damaged, the destruction of round nut, the reliability of the quality of rotor set to be difficult to guarantee.
Given this, just need a kind of novel position structure of design, guarantee quality of product, reduce manufacture cost.
The model utility content
The utility model proposes the position structure of a kind of transmission centrifugal blower fan blade wheel group and main shaft, improved the quality of centrifugal blower rotor set, convenient assembling and disassembling, economic and practical.
The technical solution of the utility model is achieved in that the position structure of a kind of transmission centrifugal blower fan blade wheel group and main shaft, comprise main shaft and the impeller sets reel that is radially positioned on the main shaft, described main shaft is provided with limited step, be with the impeller sets reel on the limited step one side main shaft, opposite side is with land, detachably fixedlys connected between impeller sets reel and the land.
Further, detachably fixedly connected between described main shaft and the impeller sets reel.
Further, be connected by bolt between described impeller sets reel and the land.
Further, described impeller sets reel is provided with the bayonet socket that adapts with limited step near an end inwall of land.
Further, the positioning key that described main shaft is provided with locating slot and matches, described impeller sets reel is provided with the locating groove that adapts with positioning key.
The beneficial effects of the utility model are: the transmission centrifugal blower fan blade wheel group that the utility model provides and the position structure of main shaft adopt land that main shaft and impeller sets reel are fixed, prevent that impeller sets from endwisely slipping at main shaft, connect by positioning key again, the impeller sets reel that makes is circumferentially fixing at main shaft, and in dismounting, only bolt need be screwed down, positioning key withdrawed from getting final product from the right side, realized the accurate location of main shaft and impeller sets, simultaneously structural stability, easy accessibility.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 2 is the utility model embodiment's scheme of installation.
Among the figure: 1, main shaft; 2, impeller sets reel; 3, limited step; 4, land; 5, positioning key; 6, locating slot; 7, locating groove; 8, bayonet socket.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
A kind of transmission centrifugal blower fan blade wheel group as shown in Figure 1 and Figure 2 and the position structure of main shaft, comprise main shaft 1 and the impeller sets reel 2 that is radially positioned on the main shaft 1, described main shaft 1 is provided with limited step 3, be with impeller sets reel 2 on the limited step 3 one side main shafts 1, opposite side is with land 4, detachably fixedlys connected between impeller sets reel 2 and the land 4.
As preferably, described impeller sets reel 2 is provided with the bayonet socket 8 that adapts with limited step 3 near an end inwall of lands 4.Bayonet socket 8 is used for locating impeller sets reel 2, and land 4 is fixed on the bayonet socket 8 of impeller sets reel 2 on the limited step 3, prevents impeller sets reel 2 axial float on main shaft 1.
As preferably, the positioning key 5 that described main shaft 1 is provided with locating slot 6 and matches, described impeller sets reel 2 is provided with the locating groove 7 that adapts with positioning key 5.By positioning key 5 that main shaft 1 is fixing with impeller sets reel 2, prevent impeller sets reel 2 circumferentially rotation on main shaft 1.
As preferably, be connected by bolt between described impeller sets reel 2 and the land 4.Can make things convenient for the user to load and unload by the bolt connection.
The transmission centrifugal blower fan blade wheel group that the utility model provides and the position structure of main shaft 1 adopt land 4 that main shaft 1 and impeller sets reel 2 is fixing, connect by positioning key 5 again, the impeller sets reel 2 that makes is circumferentially fixing at main shaft 1, and in dismounting, only bolt need be screwed down, positioning key 5 withdrawed from from the right side get final product, realized the accurate location of main shaft 1 with impeller sets, simultaneously structural stability, easy accessibility.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
