Description
Technical field
The utility model relate to a kind of assembled encapsulation type powder core reducing noise.
Background technology
Powder core of the prior art in the course of the work noise ratio is comparatively large, is 28dB, has a negative impact to the normal life and work of people when 7KHz frequency operation.And the cost of goods manufactured reducing noise in prior art is higher, product structure is complicated, and therefore how reducing noise is the major issue preparing powder core.
Summary of the invention
The purpose of this utility model is: provide that a kind of technique is simple, low cost of manufacture and effectively can reduce the powder core of noise.
The technical scheme of powder core of the present utility model is: a kind of powder core, it is set to ring-type shape, it is characterized in that: at least comprise two parts, each several part is assemblied to form an entirety, the non-magnetic shell of powder core arranged outside, powder core wraps by non-magnetic shell, and non-magnetic shell and powder core embedding are integrated.
Optimally, each several part can agree with on basis circlewise, shape and volume any.
Optimally, each several part is by bonding one-tenth entirety.
Optimally, non-magnetic shell is set to plastic casing.
Optimally, non-magnetic shell is provided with the cannelure identical with powder core shape, and arranges the end cap of one and cannelure cooperation.
Optimally, non-magnetic shell and powder core pass through epoxy resin encapsulated.
Optimally, ring-type is annulus or Fang Huan.
The technical program adopts assembled embedding form, compares traditional product, by original 28dB noise reduction to below 15dB, cost of manufacture is identical with traditional product, lower than the production cost of existing reduction noise, and effect is better than prior art, and structure is very simple.
The technical program each several part shape and volume arbitrarily, are conveniently produced, cost-saving.
The technical program adopts cohesive material bonding, and erection method variation, is conducive to the enforcement of scheme.
The technical program adopts plastic casing, and plastic casing cost compare is low, and plasticity is relatively good.
The non-magnetic shell of the technical program is provided with the hollow cylindrical groove identical with powder core shape, and the end cap of one and hollow cylindrical slot fit is set, during assembling, powder core puts into hollow cylindrical groove, then end cap is put well, carry out embedding, the non-magnetic shell of this structure assembles up fairly simple, and noise reduction is also relatively good.
The technical program adopts epoxy resin to carry out embedding, and embedding is simple, effectively can reduce noise.
The technical program annular can be annulus or Fang Huan, and convenient production, can be suitable for different operational environments.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Embodiment 1:
As shown in the figure, the technical scheme of powder core of the present utility model is: a kind of powder core, it is set to circular, comprise two parts, each several part is assemblied to form an entirety, the non-magnetic shell of powder core arranged outside, shell is by powder core internal and external circumference curved surface and one end parcel, non-magnetic shell and powder core embedding are integrated, two parts can agree with on circular basis, shape is identical with volume, two parts are by bonding one-tenth entirety, non-magnetic shell is set to plastic casing, non-magnetic shell is identical with powder core shape, its one end is provided with the circular breach agreed with powder core, and a circular end cap is set, non-magnetic shell and powder core pass through epoxy resin encapsulated.
Powder core of the present utility model is set to circular, in manufacturing process, powder core is divided into two parts to be pressed separately, each several part is formed a whole by erection method, the assembled cohesive material that can adopt carries out boning or connecting, the shell with non-magnet material such as plastic production is added outside powder core, shell have with shell one and add liquid-state epoxy resin in the non-magnetic enclosure cannelure of pipe that can agree with powder core, powder core is put into and carries out embedding, end cap is buckled the most at last, completes whole manufacturing process.
Embodiment 2:
The difference of the present embodiment and embodiment 1 is, the powder core of the present embodiment comprises three parts.
Embodiment 3:
The difference of the present embodiment and embodiment 1 is, the powder core of the present embodiment comprises four parts.
Embodiment 4:
The difference of the present embodiment and embodiment 1 is, the powder core side of the being set to ring-type of the present embodiment.
Embodiment 5:
The difference of the present embodiment and embodiment 1 is, the powder core of the present embodiment is set to two C shape semi-ring powder cores.
