Description
Technical field
The utility model relates to a kind of component of blower fan, is specifically related to a kind of blower fan support device.
Background technique
Blower fan is a kind of for compressing and carry the machinery of gas, and from energy viewpoint, it is the one machinery mechanical energy of prime mover being changed into gas energy.Centrifugal blower is formed primarily of critical pieces such as intake grill, impeller, spiral cases, be generally used for the room ventilation ventilation of the buildings such as factory, also can be used for the high pressure forced ventilation of boiler, forge etc., and be applied to mass transport etc. occasion, the centrifugal force mainly utilizing vane rotary to produce makes medium obtain energy, is then static pressure through spiral case and volute outlet diffuser by part kinetic transformation.The kind of conventional centrifugal blower conveying gas be air or other nonflammable not easily sudden and violent, to the non-corrosive gas of steel.Current centrifugal blower support device adopts fixed support, is fixed in by impeller in rotating shaft, causes like this installing inconvenience, impeller side plate Rig up error mutability row; When frequency changes, along with the change of fan blade diameter, Dimensions is too many, produces extremely inconvenience.
Summary of the invention
The utility model object provides a kind of blower fan support device to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of blower fan support device, it comprises Blower Housing, be arranged on the arbor of Blower Housing central authorities, be fixed on arbor and outer side surface has the supporting and location cover of multiple tapped hole, the impeller be arranged in Blower Housing, one end are fixed on the other end in supporting and location thread die cutting hole and are fixed on many struts on impeller, described strut is provided with the adjusting bolt for regulating strut length.
Optimally, described supporting and location cover is fixedly connected with by locking nut with strut.
Optimally, described impeller is fixedly connected with by lock bolt with strut.
Optimally, described arbor is fixed on Blower Housing central authorities by the bearing being installed on its two ends.
Optimally, described strut is identical with the tapped hole quantity that supporting and location overlaps.
Further, described strut is 3 ~ 8.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model blower fan support device, strut is utilized supporting and location cover and impeller to be fixed on the one hand, thus impeller is fixed on arbor, be conducive to the replacing of impeller, maintenance and installation; On the other hand adjusting bolt is set at strut, thus the length of strut can be regulated, go for the impeller of different-diameter, be beneficial to mass production.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model blower fan support device;
Wherein, 1, Blower Housing; 2, arbor; 3, impeller; 4, supporting and location cover; 5, strut; 6, adjusting bolt; 7, lock bolt; 8, locking nut; 9, motor; 10, bearing.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Blower fan support device as shown in Figure 1, mainly comprises Blower Housing 1, arbor 2, impeller 3, supporting and location cover 4 and strut 5.
Wherein, arbor 2 is arranged on Blower Housing 1 central authorities, can arrange bearing 10, thus be fixed on Blower Housing 1 at its two ends; Impeller 3 is rotatably arranged in Blower Housing 1; Supporting and location cover 4 is fixed on arbor 2, and its outer side surface is provided with multiple tapped hole; The adjustable length of strut 5, its one end is fixed in the tapped hole of supporting and location cover 4, the other end is fixed on impeller 3, thus utilize strut 5 to be fixed on arbor 2 by impeller 3, be conducive to the replacing of impeller 3, maintenance and installation, and strut 5 is provided with adjusting bolt 6, can be used for regulating the length of strut 5, go for the impeller of different-diameter, overcome the defect that Dimensions is too many, be beneficial to mass production.
In the present embodiment, one end of strut 5 is overlapped 4 by locking nut 8 (or bolt) with supporting and location and is fixedly connected with, the other end is fixedly connected with impeller 3 by lock bolt 7, and strut 5 is identical with the tapped hole quantity that supporting and location overlaps 4, tapped hole can overlap 4 outer side surface circumferential directions 3 ~ 8 at supporting and location, such one side facilitates the dismounting of impeller 3, can improve the join strength of impeller 3 and arbor 2 on the other hand.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
