Abstract
The utility model discloses a fan with a novel bearing block. The bearing block is formed by a plurality of bearing brackets in a combined mode. Each bearing bracket is a strip plate which is divided into an arc section, a middle section and a connecting section in sequence. The connecting section is twisted by 90 degrees relative to the middle section. The arc section is provided with a bend angle relative to the middle section. The arc section is provided with a connecting lug at a free end, and the connecting lug forms the bend angle with the arc section. Bolt holes are formed in the connecting lug, the free end of the connecting section, and the position, close to the arc section, of the middle section. After the plurality of bearing brackets are combined, the arc sections of the plurality of bearing brackets form a closed circular hoop. The bolt holes in the connecting lugs are overlapped with the bolt holes in the middle sections of the adjacent bearing brackets and are connected through bolts. Due to the fact that the bearing block is formed by the plurality strip-plate-shaped bearing brackets in a combined mode, the bearing brackets can be manufactured in twisting, stamping and bending modes, and accordingly the fan with the novel bearing block has the advantages of being convenient to machine and assemble, and favorable for improving production efficiency.
Description
Technical field
The utility model belongs to the blower fan technical field, relates in particular to a kind of blower fan with novel bearing seat.
Background technique
Blower fan is the critical component in ventilation equipment or the ventilation system.Blower fan usually by base, be located at the spiral case on the base and the impeller be located in the spiral case constitutes.Wherein, the spiral case both sides of blower fan need arrange bearing support, in order to support impeller by axle.At present, the bearing support of prior art is the structure that adopts many spokes of round bush welding, and the bearing support of such structure needs a series of loaded down with trivial details manufacturing procedures such as turning, welding just can produce, and efficient is lower.
The model utility content
For this reason, technical problem to be solved in the utility model provides a kind of blower fan with novel bearing seat, to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of blower fan with novel bearing seat, comprise base, be fixed on the spiral case on the base, and be located at impeller in the spiral case, described spiral case is connected with bearing support at intake grill, be provided with bearing in the described bearing support, it is characterized in that: described bearing support is combined by many bearing bracket stands, described bearing bracket stand is a batten, be divided into arcuate segment successively, intermediate section and linkage section, described linkage section reverses 90 ° with respect to intermediate section, the relative intermediate section of described arcuate segment has bent angle, described arcuate segment has the engaging lug that forms bent angle with arcuate segment at free end, described engaging lug, the free end of linkage section and intermediate section all have bolt hole near the position of arcuate segment, and many bearing bracket stands are after combination, and the arcuate segment of many bearing bracket stands forms closed circular boop, wherein the bolt hole of engaging lug and adjacent shaft bolster the middleware section on bolt hole coincide together and be connected with bolt, the bolt hole of described linkage section is connected the edge of intake grill by bolt.
In preferred implementation of the present utility model, the cross section of described arcuate segment is arc, and such connecing makes bearing fixing firm.
Bent angle between bent angle between described arcuate segment and the intermediate section and arcuate segment and the engaging lug is identical.
In the utility model embodiment, described bearing bracket stand has 3, between described arcuate segment and the intermediate section and the bent angle between arcuate segment and the engaging lug be 120 °.
It more than is exactly bearing support of the present utility model, it adopts the bearing bracket stand of a plurality of batten shapes to combine, bearing bracket stand only need adopt and reverse, the mode of punching press, bending can create, and this has processing, advantage easy to assembly with respect to prior art, is conducive to enhance productivity.
Description of drawings
Below in conjunction with accompanying drawing and concrete enforcement the utility model is elaborated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the structural representation of bearing support;
Fig. 4 is the structural representation of bearing bracket stand;
Fig. 5 is the unfolded drawing of overlooking of Fig. 4;
Fig. 6 be among Fig. 4 A-A to sectional view;
Among the figure:
The 10-base, 20-spiral case, 30-impeller, 40-bearing support, 41-bearing, 100-bearing bracket stand, 110-arcuate segment, 120-intermediate section, 130-linkage section, 140-engaging lug, 150-bolt hole, 200-circular boop.
Embodiment
As depicted in figs. 1 and 2, the blower fan with novel bearing seat of the present utility model, it comprises base 10, is fixed on the spiral case 20 on the base 10, and is located at the impeller 30 in the spiral case 20, is connected with the bearing support 40 of support impeller 30 at the intake grill 21 of spiral case 20.In conjunction with shown in Figure 3, this bearing support 40 is combined by 3 bearing bracket stands 100, is provided with bearing 41 in the bearing support 40.
As Fig. 4, shown in Figure 5, bearing bracket stand is a batten, be divided into arcuate segment 110, intermediate section 120 and linkage section 130 successively, wherein, linkage section 130 reverses 90 ° with respect to intermediate section 120, arcuate segment 110 relative intermediate sections 120 have 120 ° bent angle, and arcuate segment 110 also has the engaging lug 140 that forms 120 ° of bent angles with arcuate segment 110 at free end.The free end of engaging lug 140, linkage section 130 and intermediate section 120 all have bolt hole 150 near the position of arcuate segment 110.
Again as shown in Figure 3, after 3 bearing bracket stand 100 combinations, the arcuate segment 110 of these 3 bearing bracket stands 100 forms closed circular boop 200, and this circular boop 200 just is used for fixing bearing.Wherein, the bolt hole of the engaging lug 140 of a bearing bracket stand and adjacent another root bearing bracket stand the middleware section on bolt hole coincide together and be connected with the bolt (not shown), and linkage section 130 upper bolt holes are connected the edge of intake grill 21 by bolt.
As shown in Figure 6, for guaranteeing bearing 41 fixations, the cross section of arcuate segment 110 is arc.
It more than is exactly blower fan of the present utility model, its bearing support adopts the bearing bracket stand of a plurality of batten shapes to combine, bearing bracket stand only need adopt and reverse, the mode of punching press, bending can create, and this has processing, advantage easy to assembly with respect to prior art, is conducive to enhance productivity.
