Abstract
The invention relates to a noise-eliminating shock absorbing structure of a motor cooler, which comprises a casing plate, glass silk cottons, glass silk cloth, a perforated plate and reinforcing ribs. The casing is an external plate for the cooler, the inner side of the casing plate is provided with the glass silk cottons, the glass silk cloth, the perforated plate and the reinforcing ribs. Adopting the noise eliminating structure composed of the glass silk cottons and the perforated plate, the noise-eliminating shock absorbing structure of the invention can reduce the operating noise of motor significantly. Simultaneously, the reinforcing rib is adopted to, in the one hand, divide the noise eliminating structure into a plurality of small units so that the glass silk cottons can be placed more evenly to avoid the generation of larger displacement in use, in the other hand, reinforce the strength of the casing plate to enhance the rigidness of the cooler integrally, thus the noise-eliminating shock absorbing structure plays the role of wideband noise elimination and shock absorption.
Description
Technical field
The present invention relates to noise and vibration control field, be specifically related to a kind of noise reduction and vibration-proof structure of AC/DC motor cooler.
Background technology
At present, the shell of existing AC/DC motor cooler only is the steel plate of one deck 4 millimeter, does not make noise reduction and vibration reducing measure.When main motor and cooler moved simultaneously, vibration and noise that main motor produces can be delivered in the environment by cooler, and be more outstanding expressively in pot motor especially.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, provide a kind of and can reduce motor operation noise, reduce the vibration silencer structure of the motor of vibration with cooler, adapt at present gradually in strictness to noise and vibration control requirement.
Technical scheme of the present invention is as follows:
A kind of motor vibration silencer structure of cooler, comprise Shell Plate, glass silk flosssilk wadding, glass wool cloth, perforated plate and stiffener, described stiffener is welded on the Shell Plate inboard according to identical spacing, framework middle berth at Shell Plate and stiffener composition is filled with the glass silk flosssilk wadding, on described glass silk flosssilk wadding upper berth glass wool cloth is arranged, be welded with perforated plate at described glass wool cloth upside.
The present invention has the following advantages:
The present invention can significantly reduce running noise of motor owing to adopted the glass silk flosssilk wadding and the noise-reducing structure of perforated plate composition.The employing of reinforcement simultaneously is divided into a plurality of junior units to noise-reducing structure on the one hand, makes the placement of glass silk flosssilk wadding more even, in use is unlikely to produce big displacement; Strengthen the intensity of Shell Plate on the other hand, improved the rigidity of cooler on the whole.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention includes Shell Plate 1, glass silk flosssilk wadding 2, glass wool cloth 3, perforated plate 4 and stiffener 5.Shell Plate 1 is the outer panels of cooler, and vertically every the same distance reinforcement 5 of burn-oning, the framework middle berth of forming at Shell Plate 1 and reinforcement 5 is inserted glass silk flosssilk wadding 2 then, at glass silk flosssilk wadding 2 upper berth glass wool cloths 3, prevents that glass silk flosssilk wadding 2 from dropping out on Shell Plate 1.The perforated plate 4 of burn-oning in glass wool cloth 3 inboards at last.
The realization principle of noise reduction: after air entered the cooler inner chamber, sound wave diffused to the inwall of cooler, because the shell mechanism of cooler has been done the special processing as Fig. 1, the glass silk flosssilk wadding is equivalent to a resistance noise reduction effect for 2 layers, absorbed high-frequency noises.Perforated plate is equivalent to a reactive muffler for 4 layers, absorbs the Low Medium Frequency noise.Both combine, and are equivalent to form a complex muffler.
The realization principle of vibration damping:, be starting point to strengthen cooler rigidity for the passive vibration damping of cooler.In the structure as Fig. 1, the welded and installed of reinforcement 5 and Shell Plate 1 is significantly increased 1 section inertia of Shell Plate, thereby has increased the bulk strength of cooler.
In sum, behind employing the present invention, cooler can improve significantly aspect noise and the vibration.
The above is the preferred embodiments of the invention only, the invention is not restricted to above embodiment.Be understood that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present invention and design, all should think to be included within protection scope of the present invention.
Claims (1)
