Abstract
The present invention relates to a kind of high-strength cast iron motor fan housing, including connecting bolt, bonnet, conventional stud, fan housing body, the fan housing body is evenly equipped with four axial boss by HT200 gray cast iron castables in fan housing body, four mounting holes are provided with four axial boss.The front end of the connecting bolt is provided with the preceding thread matched with the lug of bonnet 2, and rear end is machined with the deep hole thread for fan housing fastening.The bonnet is fixed on support by connecting bolt, and four axial boss are closely contacted in the rear end of connecting bolt in the fan housing body, and are locked with connecting bolt with conventional stud.The present invention can be used in the presence of a harsh environment, prevent motor from damage fan due to collision.
Description
Technical field
The present invention relates to a kind of cast iron electric machine, more particularly to a kind of high-strength cast iron motor fan housing.
Background technology
Motor rear end is typically provided with fan and fan housing, and fan is to cool down the heat produced during motor rotation, and fan housing is to protect
Shield fan is hardly damaged normal work and the flowing of guiding wind direction support side, and the danger for even more preventing people from touching fan generation is asked
Topic.But existing fan housing is mostly Steel Sheet, motor when industrial and mineral and field building trade are used, because environment is disliked
It is bad, motor can be collided unavoidably, motor fan housing is deformed and is damaged fan, so as to have influence on the integral protection of motor
Can, the machine of sending a telegraph cannot normal work.Furthermore existing cast iron fan housing be all radially installed on support, due to cast member inner circle not
Rule, it is that point-to-point contact is fixed that installation always has direction, and the vibrations that once work is produced of such motor can make point-to-point for a long time
Contact position bolt looseness, so as to have influence on the integral protection performance of motor.
The content of the invention
For defect present in above-mentioned prior art, the technical problems to be solved by the invention are to provide one kind and can prevent
Motor damaged in collision fan, and the upper of electric machine stand is more fastened on, so as to improve motor integral protection performance and safety
The high-strength cast iron motor fan housing of measure.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of high-strength cast iron motor fan housing, bag
Connecting bolt, bonnet, conventional stud, fan housing body are included, the fan housing body is by HT200 gray cast iron castables, fan housing body
Four axial boss are inside evenly equipped with, four mounting holes are provided with four axial boss.
The front end of the connecting bolt is provided with the preceding thread matched with the lug of bonnet 2, and rear end is machined with for fan housing fastening
Deep hole thread.
The bonnet is fixed on support by connecting bolt, and four axial boss are closely contacted in the fan housing body
In the rear end of connecting bolt, and it is locked with connecting bolt with conventional stud.
The beneficial effects of the invention are as follows：The high-strength cast iron motor fan housing that the present invention is provided, the design of fan housing mounting hole is existed
Axial location, is designed using sunk, and motor monnolithic case size is not hindered, is attached by the connecting bolt of particular design
Install.Bonnet is first filled during assembling, is fixed on support with connecting bolt, fan housing is then installed, enable four boss in fan housing tight
Close contact is in the rear end of connecting bolt, then reinforces conventional stud locking.Can in the presence of a harsh environment use, prevent motor due to touching
Hitting damages fan, so as to improve motor integral protection performance and safety measure.
Fan housing mounting hole design in axial location, this installation can well reinforce fan housing in itself, can prevent motor due to
Vibrations make bolt looseness, so as to improve motor integral protection performance.

Specific embodiment
Embodiments of the invention are described in further detail below in conjunction with brief description of the drawings.
As shown in Figures 1 to 5, high-strength cast iron motor fan housing of the invention, including fan housing body 4, connecting bolt 1, after
Lid 2, conventional stud 3.
Such as Fig. 2, shown in 3, fan housing body 4 is evenly equipped with four axial directions by HT200 gray cast iron castables in fan housing body 4
Boss, is provided with four mounting holes 5 in four axial boss.Mounting hole 5 is that connecting bolt 1 passes through the passage being locked on support.
Such as Fig. 4, shown in 5, preceding thread and the lug of bonnet 2 of the front end of connecting bolt 1 match, and rear end is machined with deep hole spiral shell
Line.The rear end deep hole thread of connecting bolt 1 is the installation screw of fan housing fastening.
It is as shown in Figure 1 in assembling in the embodiment of the present invention：Bonnet 2 is first filled during assembling, machine is fixed on connecting bolt 1
On seat, fan housing body 4 is then installed, four axial boss in fan housing body 4 is closely contacted in the rear end of connecting bolt,
Conventional stud 3 is reinforced again to lock.
