Abstract

The invention relates to a device for damping the vibrations and noise of an electric motor (1) embedded in a housing (5) by three elastic blocks (2, 3, 4), wherein the stator is formed by the elastic blocks (3) and (4) and the rotor is fastened by means of the elastic block (2).

Description

The vibration damping of motor and noise eliminator
Technical field
The present invention relates to a kind of device that in various technical scopes, is used for motor vibration damping and noise elimination.
Background technology
Motor produces vibration and noise at run duration.Its vibration damping with eliminate the noise main at present when motor is cased by by means of different linings, seal, cotton lining or the like to the whole casing vibration damping with eliminate the noise and realize.The shortcoming of present state of the art is less vibration damping and noise elimination effect, big requirement aspect installing space, thus and cause higher cost.
Summary of the invention
Eliminate above-mentioned deficiency by technical scheme of the present invention.Relate to flexible motor setting-in at this.Motor by means of several elastomer block setting-ins in the enclosure, described elastomer block not only cushion motor stator and also the buffering motor rotor.Producing beginning from it is favourable with regard to vibration damping and noise elimination, thereby and prevents to continue to transmit.
Description of drawings
End view by device of the present invention shown in Figure 1, wherein motor casing illustrates with cutting open.Its perspective view shown in Figure 2.At the view that is similar to Fig. 1 and 2 shown in Fig. 3 and 4, however not charged motivation.Fig. 5 illustrates the profile of motor and shell halfbody.Fig. 6 illustrates the thin portion of the elastomer block of rotor.Be to have tripod and in Fig. 7 not with the perspective view in the motor front of elastomer block, the perspective view that has elastomer block shown in Figure 8.
Embodiment
At the end view of pressing device of the present invention shown in Fig. 1 and 2, wherein the shell 5 of motor 1 illustrates with cutting open.The second shell halfbody generally is of similar shape, yet forwards the position of mirror-inverted to.Advantageously, two halfbodies detachably connect into an integral body.
This device is made of three elastomer block 2,3,4, and wherein stator is fixed by means of elastomer block 3 and 4, and rotor is fixing by means of elastomer block 2.It is right in these two accompanying drawings travelling gear to be shown also as an example, is made of the worm gear 50 and the gear 51,52 and 53 that are contained on 11 on the motor.
At the view that is similar to Fig. 1 and 2 shown in Fig. 3 and 4, however not charged motivation 1. Visible contact point 30,31,31 in these two accompanying drawings ' and 32, described contact point is formed in the shell fin 5.In the second shell halfbody, constitute abreast contact point 30 ', 31 ", 31 " ' and 32 '.Relate generally to be shaped as circular or oval-shaped space, the outline of this shape copying motor 1 or elastomer block 2,3,4.
Elastoplast piece 4 guarantees to prevent that motor 1 is along axially and move radially.Described elastoplast piece 4 has the shape of flange, and is set on the back side 15 of motor stator.The contact point 30,30 of elastomer block 4 on being formed in shell fin 5 ' on flexibly be embedded in the shell 5 abreast.Elastomer block 4 is provided with a liner 24, and this liner prevents that motor is along axially and move radially.Liner 24 is positioned at elastomer block 4, and abuts on the motor on the level of armature spindle.The material of liner 24 can be made by any material, for example plastics or metal.
Elastoplast piece 3 guarantees to prevent that motor is along axially and move radially.Described elastoplast piece 3 has the shape of flange, and is set on the front 10 of stator of motor 1.The contact point 31,31 of elastomer block 3 on being formed in shell fin 5 ', 31 ", 31 " ' on flexibly be embedded in the shell fin abreast.
The profile of motor 1 shown in Figure 5 and shell 5.Fig. 6 illustrates the profile of thin portion of the elastomer block 2 of rotor.Elastoplast piece 2 be placed on space 26 by a retaining element 20, one with the form of the cover that has space 26 and crimping 27 and have in rubber rings 21 in the fixed cap 22 of roll forming shape on inclined-plane constitute, it is flexibly settled by rubber ring.Freely place in retaining element 20 end of armature spindle 11.Armature spindle 11 rotates in retaining element 20.Fixed cap 22 be placed on space 32,32 in the shell fin of motor 1 ' in.
Having tripod 12 shown in Fig. 7 and 8 not with the front perspective view of the motor 1 of elastomer block 3, the situation that has elastomer block 3 shown in Figure 8 in addition.The opening 25 that is shaped as the trident star is arranged in elastomer block 3, and the tripod 12 that is fixed to motor 1 front 10 is embedded in this trident starriness.
Industrial applicibility
The device that is used for motor vibration damping and noise elimination can use in the technical field of various use motor.
