Description

A kind of air blast cooling protective cover
Technical field
The utility model relates to permanent magnet speed regulation device field, particularly relates to a kind of air blast cooling protective cover.
Background technology
Permanent magnet speed regulation device is a kind of drive apparatus utilizing electromagnetic induction principle work, and its primary structure comprises magnet rotor and conductor disc, is provided with air gap between conductor disc and magnet rotor, and conductor disc is connected with motor, and magnet rotor is connected with load.When conductor disc during High Rotation Speed, can cut the magnetic line of force in magnet rotor magnetic field under motor drives, produce induced magnetism moment of torsion, thus drive loaded work piece, so just achieve the noncontact torsion transmission between motor and load.This structure can realize flexibly connecting between motor and load as coupler or speed regulating device, there is the effect of energy efficient, therefore permanent magnetic transmission device is widely used in the motor transmission system of all trades and professions, but because it exists the slippage of about 4%, eddy-current heating can be produced in conductor disc, and too high temperature can cause magnet rotor demagnetization, therefore for conductor disc cooling is the key designed, non-working surface normally in conductor disc in conventional design arranges aluminium heat sink, object is when conductor disc rotates, and heat is taken away by the disturbance forming air-flow.
Through practical proof; it is this that by conductor disc self, to rotate the heat taken away be limited; because for the sake of security; usually also will protective cover be set in the outside of conductor disc; to prevent from flying out in High Rotation Speed, thing is hurted sb.'s feelings, and protective cover makes the circulation of air-flow be obstructed, and heat is difficult to be pulled away; this problem is more obvious in high-power permanent magnet drive system, and urgently to be resolved hurrily.
Summary of the invention
The purpose of this utility model is to provide a kind of air blast cooling protective cover; overcome the deficiencies in the prior art; optimize protective cover structure; defencive function can be realized; refrigerating function can be realized again; improve the operating heat dissipation problem of permanent magnetic transmission device, for the development of more high-power permanent magnet transmission device provides a solution.
To achieve these goals, the technical solution of the utility model is such:
A kind of air blast cooling protective cover; comprise cover body; described cover body is up-down structure; be provided with dividing plate between upper outlet body and lower cover, upper outlet body is divided into left and right two parts by baffle plate, and wherein a part is provided with blower fan; another part is provided with air channel; the air outlet of blower fan is connected with lower cover, and the one end in described air channel is connected with lower cover, and the other end in air channel is provided with opening on upper outlet body.
Described lower cover is that left and right splits structure.Arc liner plate is provided with in described lower cover.
The sidewall of described lower cover opens observation window, and window place is provided with movable panel.
The base of described movable panel is connected by folding with lower cover, and the top margin of movable panel is connected by rod bolt with lower cover.
The air inlet of described blower fan is opened on the sidewall of upper outlet body.
Described air channel is formed by wind deflector and upper outlet body side walls enclose.Described air channel is curved channel.
Compared with prior art, the beneficial effects of the utility model are: the blower fan that 1) housing is built-in and arc air channel, are conducive to forming smooth airflow circulating, alleviate operation noise; 2) fast the heat that slippage produces can be taken away, ensure that p-m rotor always works in below demagnetization temperature, be conducive to the long-term safety stable operation of permanent magnetic transmission device, and the power of air cooling permanent magnet devices can be improved further; 3) lower cover of left and right fractionation structure facilitates the installation of permanent magnetic transmission device especially, can be applicable to the permanent magnetic transmission device of most of version; Observation window structure makes cover interior state very clear, and these are all that installation is provided convenience condition.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment external structure schematic diagram;
Fig. 2 is the utility model embodiment internal structure schematic diagram (front side board is hidden).
In figure: 1-upper outlet body, 2-lower cover, 3-dividing plate, 4-baffle plate, 5-blower fan, 6-air channel, 7-wind deflector, 8-installation axle hole, 9-observation window, the movable panel of 10-, 11-folding, 12-rod bolt, 13-liner plate.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, Fig. 2; it is a kind of air blast cooling protective cover of the utility model example structure schematic diagram; this cover body is up-down structure; dividing plate 3 is provided with between upper outlet body 1 and lower cover 2; upper outlet body 1 is divided into left and right two parts by baffle plate 4, and wherein a part is provided with blower fan 5, and another part is provided with air channel 6; the air outlet of blower fan 5 is connected with lower cover 2, and the air inlet of blower fan 5 is opened on the sidewall of upper outlet body 1.The one end in air channel 6 is connected with lower cover 2, and the other end in air channel 6 is provided with opening on upper outlet body 1.For reducing resistance, air channel 6 is curved channel.In embodiment, air channel 6 is formed by the side walls enclose of wind deflector 7 and upper outlet body 1.As the case may be, air channel also can form by tubular article is curling.
Arc liner plate 13 in lower cover 2 form curved channel, the resistance of air circulation can be reduced.
When the utility model protective cover is used for high-power permanent magnet transmission device; the main frame of permanent magnetic transmission device is contained in lower cover 2 at (comprising conductor disc and p-m rotor); the power shaft of main frame and output shaft are stretched out by the installation axle hole 8 of lower cover; in order to improve the convenience of installation; lower cover 2 may be selected to be left and right and splits structure; this situation is applicable to the transformation and upgrade of old protective cover, and now lower cover 2 splits by about the central axis of installation axle hole 8, is optimal state.
