The main body of this fan casing is tubular shell, tubular shell one end is fixedly connected with motor rack both sides, and be motor cabinet in the middle part of motor rack, motor cabinet is provided with the mounting hole being fixedly connected with motor, and the rotary shaft hole to coordinate with machine shaft, rotary shaft hole and described tubular shell concentric; Described motor rack is relative to symmetrical centered by rotary shaft hole axle center.By motor rack being arranged at the end of fan casing, thus reducing motor rack, motor to the impact of fan casing exhaust outlet, improving air output.
In order to reduce the impact of motor rack on fan casing ventilation as far as possible, described motor rack is except the position be connected with described tubular shell end, and the part beyond described motor cabinet is hollow out.
In order to make the connection between motor rack and tubular shell comparatively solid and reliable, described motor rack side and described tubular shell end are same disjunctor, and motor rack opposite side and described tubular shell end are for being welded and fixed.Concrete scheme structure is: described motor rack is that in the middle part of rectangular frame, disjunctor is provided with circular electric support, and side minor face and the described tubular shell end of rectangular frame are same disjunctor, and opposite side minor face and the described tubular shell welding edges of rectangular frame are fixed.
Further, two long sides of described rectangular frame are provided with right angle flange, right angle, both sides flange is provided with the power supply string holes be centrosymmetric relative to described rotary shaft hole axle center, and each right angle flange is provided with two power supply string holes, one of them power supply string holes is near described motor cabinet, and another power supply string holes is near the short brink of described rectangular frame.By designing power supply string holes, thus facilitate the installation of power line to lay, prevent power cord wrap, improve Security.
The described tubular shell the other end is provided with annular flange fitting surface, and annular flange fitting surface is provided with the attachment hole of annular array distribution.By this annular flange fitting surface, attachment hole, the installation realizing fan casing is fixed.
The corresponding described attachment hole position, the back side of described annular flange fitting surface is fixedly connected with cushion block, and cushion block is provided with the through hole alignd with attachment hole.By setting up cushion block, improve the join strength of this annular flange fitting surface, thus improve the reliability of fan casing installation.
Further, the inner hollow out of described cushion block forms elasticity collapsing structure.When annular flange fitting surface is locked with corresponding attachment face by locking element, cushion block crumple is out of shape, and prevents locking element from locking excessively on the one hand, prevents locking element from loosening on the other hand, more reliable after fan casing is assembled.
The making method of this fan casing is: described tubular shell is made by flat sheet formed by plate bending rolls, welding machine, before making tubular shell, described flat sheet one end completes the described motor rack of disjunctor in advance, when flat sheet makes formation tubular shell, again the side that motor rack is connected with tubular shell is folded, motor rack opposite side and tubular shell welding edges, namely complete the making of this fan casing.
Further, described tubular shell end is made by roll squeezing type flanger and forms annular flange fitting surface, and this annular flange fitting surface makes the attachment hole forming annular array distribution by driling machine.
The utility model structure is comparatively simple, and processing and fabricating more for convenience, not only increases the fastness of motor rack structure, and improves the ventilation of fan casing, and the case being suitable as all kinds of axial fan uses.

In figure, numbering and the name of parts are called: 1, tubular shell, 101, annular flange fitting surface, 102, attachment hole, 2, motor rack, 201, motor cabinet, 202, mounting hole, 203, rotary shaft hole, 204, right angle flange, 205, power supply string holes, 3, cushion block, 4, flat sheet.
Embodiment
Now by reference to the accompanying drawings, be specifically made as example with this fan casing, the utility model is described as follows.
As shown in Figure 3, the original material making this fan casing is one piece of flat sheet 4, and flat sheet 4 one end disjunctor is provided with motor rack 2, and motor rack 2 is rectangular frame, the minor face side of rectangular frame and flat sheet 4 disjunctor.Be provided with the circular electric support 201 of disjunctor in the middle part of rectangular frame, motor cabinet 201 is provided with the mounting hole 202 connecting motor, is provided with the rotary shaft hole 203 coordinated with machine shaft in the middle part of motor cabinet 201.Two long sides of rectangular frame are equipped with right angle flange 204, and this right angle, both sides flange 204 is provided with the power supply string holes 205 be centrosymmetric relative to rotary shaft hole 203 axle center, and each right angle flange 204 is provided with two power supply string holes 205, one of them power supply string holes 205 is near motor cabinet 201, and another power supply string holes 205 is near the short brink of rectangular frame.
The working process of this fan casing is: the tubular first flat sheet 4 being rolled into lateral opening by existing plate bending rolls, and carries out straight seam welding by welding machine to lateral opening and form complete tubular shell 1.Again as shown in Figure 4, the side that motor rack 2 is connected with tubular shell 1 is folded, after folding, make the rotary shaft hole 203 of motor rack 2 and rotary shaft hole 203 concentric of tubular shell 1.Finally by motor rack 2 opposite side and tubular shell 1 welding edges, namely make formation easy fan casing.
Conveniently this fan casing fixed installation, utilize roll squeezing type flanger to carry out roll extrusion flange to tubular shell 1 end and form annular flange fitting surface 101, made the attachment hole 102 forming several annular arrays at annular flange fitting surface 101 by driling machine, thus this fan casing is connected and fixed with fan casing position to be installed by annular flange fitting surface 101, attachment hole 102.The fan casing that this making is formed as shown in Figure 1.
In order to improve fastness when annular flange fitting surface 101 and fan casing position to be installed are fixed and reliability, the position welding cushion block 3 of the corresponding attachment hole 102 in the back side of annular flange fitting surface 101, cushion block 3 is provided with the through hole alignd with attachment hole 102.As required, cushion block 3 can be designed to inner hollow out, thus forms elasticity collapsing structure, when making the attachment hole 102 of annular flange fitting surface 101 connect locking element, prevents locking element from locking excessively or loosening.The fan casing that this making is formed as shown in Figure 2.
