Description
Technical field
The utility model relates to permanent magnet transmission technical field, particularly relates to a kind of noise reduction protective cover for magnetic actuator.
Background technology
Magnetic actuator is a kind of industrial new energy-saving equipments, form primarily of permanent magnetism body disc, conductor disc and speed adjusting gear, conductor disc and motor shaft are connected, and permanent magnetism body disc and load (blower fan, water pump) are connected, conductor disc and permanent magnetism body disc produce relative rotation, the magnetic induction line of conductor disc cutting permanent magnetism body disc, produces induced current in conductor disc, and then produces induced field and permanent magnetism body disc interacts, drive permanent magnet disc spins, and then band dynamic load rotates.When between conductor disc and permanent magnetism body disc, distance becomes large, interaction force diminishes, and load speed is slow, and when between conductor disc and permanent magnetism body disc, distance diminishes, interaction force becomes large, and load speed is fast.Therefore magnetic actuator is that this principle of application carrys out regulating load rotating speed according to needs of production, thus realizes energy-conservation object.
When magnetic actuator works, on the one hand, due to conductor disc and permanent magnetism body disc High Rotation Speed, therefore with the noise of high-decibel, need to carry out sound-deadening and noise-reducing process to it; On the other hand due to conductor disc producing induced current, conductor disc temperature raises, and therefore needs to carry out radiating treatment to it.In addition, as High Rotation Speed transmission mechanism, protecting it is also the measure that must take.Current permanent-magnet speed governor generally uses common protective cover, it possesses safeguard function, in use there is weak heat-dissipating, do not absorb the shortcoming of noise, affect stability when magnetic actuator works and fail safe, and the noise pollution that equipment produces cannot be prevented, healthy the causing of surrounding people is had a strong impact on.
Summary of the invention
The utility model provides a kind of noise reduction protective cover for magnetic actuator, integrate noise reduction, heat radiation and safeguard function, the problem of disposable solution sound-deadening and noise-reducing, wind guide and heat dispersion and security protection, can ensure that magnetic actuator is stable, safe and reliable and reduce noise pollution; Its structure is simple, and fabrication and installation are convenient, and cost is low, practical.
In order to achieve the above object, the utility model realizes by the following technical solutions:
For a noise reduction protective cover for magnetic actuator, be arranged on outside permanent magnetism body disc and conductor disc transmission device, comprise scroll casing shape cover body and supporting leg, described cover body is upper and lower two parts along horizontal axis subdivision, and passes through Flange joint; Inlet scoop is offered respectively in cover body both sides, and top sets out air port, and cover body adopts the composite material of double-deck orifice plate therebetween asbestos cloth to make.
Described air outlet place is provided with protection network, is fixed by a pair ring flange.
Compared with prior art, the beneficial effects of the utility model are:
1) integrate noise reduction, heat radiation and safeguard function, the problem of disposable solution sound-deadening and noise-reducing, wind guide and heat dispersion and security protection, can ensure that magnetic actuator is stable, safe and reliable and reduce noise pollution;
2) structure is simple, and fabrication and installation are convenient, and cost is low, practical;
3) the special-purpose assorted device that can be used as magnetic actuator uses, and has promotional value.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1-Fig. 2, it is structural representation of the present utility model, a kind of noise reduction protective cover for magnetic actuator of the utility model, be arranged on outside permanent magnetism body disc and conductor disc transmission device, comprise scroll casing shape cover body 1 and supporting leg 2, described cover body 1 is upper and lower two parts along horizontal axis subdivision, and is connected by flange 5; Cover body 1 both sides offer inlet scoop 3,4 respectively, and top sets out air port 6, and cover body 1 adopts the composite material of double-deck orifice plate therebetween asbestos cloth to make.
Described air outlet 6 place is provided with protection network 8, is fixed by a pair ring flange 7.
A kind of noise reduction protective cover for magnetic actuator of the utility model realizes noise reduction, heat radiation and safeguard function by special substance and structure, wherein, the composite material that have employed double-deck orifice plate therebetween asbestos cloth due to cover body 1 makes, therefore can there is the effect absorbing noise reduction to the high-decibel noise sent during magnetic actuator transmission, good erasure effect can be played.Because cover body 1 entirety adopts volute type structure design, there is involute contour, and be provided with inlet and outlet, discharge from top outlet inlet 6 very swimmingly along cover body 1 inner curve from inlet scoop, both sides 3,4 leaked-in air, therefore there is good wind guide and heat dispersion function.In addition, the transmission mechanism of permanent magnetism body disc and conductor disc encloses by cover body 1, prevents high-speed rotary part from producing injury to human body or other equipment, therefore has function of safety protection.
The inlet scoop 1 of cover body 1 both sides can be passed for power transmission shaft between conductor disc and motor, inlet scoop 24 can be passed for the connecting axle between permanent magnetism body disc and load, while the operation not affecting mechanism, diameter because of inlet scoop is greater than the diameter of axle, when transmission mechanism operates, negative pressure is formed, from can air intake simultaneously between inlet scoop 1, annulus between inlet scoop 24 and respective shaft in cover body 1.
Below cover body 1, both sides are respectively provided with 2 supporting legs 2, and by being bolted on frame or ground, make overall structure more stable.
Claims (2)
1. for a noise reduction protective cover for magnetic actuator, be arranged on outside permanent magnetism body disc and conductor disc transmission device, it is characterized in that, comprise scroll casing shape cover body and supporting leg, described cover body is upper and lower two parts along horizontal axis subdivision, and passes through Flange joint; Inlet scoop is offered respectively in cover body both sides, and top sets out air port, and cover body adopts the composite material of double-deck orifice plate therebetween asbestos cloth to make.
2. a kind of noise reduction protective cover for magnetic actuator according to claim 1, it is characterized in that, described air outlet place is provided with protection network, is fixed by a pair ring flange.
