Description
Technical field
The utility model relates to the plug-in type concrete vibrating device of dress in a kind of motor.
Background technology
In building operations, during for the concrete of tamping cast in the vibratory equipments such as employed immersible concrete vibrator or vibrating head, electric machine external formula and motor built-in type two classes can be arranged by the set-up mode of its drive motors.Wherein the vibratory equipment of electric machine external formula has many defectives that self are difficult to overcome and problem owing to be subjected to the restriction of factors such as its structure design, has belonged to the product that will be eliminated.Basic structure at present existing this class motor built-in type vibratory concrete equipment, all be by afterbody to the casing of end, prolong axis and be provided with driving mechanism unit that comprises motor stator and rotor and the eccentric whirling vibration unit that is driven by it, rotor wherein and the structural member that is integral form by its eccentric whirling vibration unit that drives rotation.Therefore, include this integral structure component of rotor and eccentric whirling vibration unit, the common supporting of 3 bearing arrangements at the two switch site place that must be through being arranged at its two ends and middle part thereof respectively and being fixed in the interior space of casing.The electric power connection line of motor-driven mechanism unit is then drawn by afterbody.Because the rotor in its structure is the structural member of integral form with the eccentric whirling vibration unit employing that is driven rotation by it, for reducing the phase mutual interference between its dependency structure part when working, must propose have higher required precision to the processing and manufacturing and/or the assembling of these parts.Simultaneously, because the exciting force that the dither power that the eccentric whirling vibration unit that rotates at a high speed during work forms is produced mainly is to be born by the location bearing that is positioned at its middle part, and be subjected to the restriction of structure design, the location bearing at this middle part can only adopt expensive location bearing structures such as needle bearing at present, but the exciting force that this bearing arrangement can bear is limited.Therefore, even reached higher processing and/or assembly precision requirement, also be difficult to avoid phase mutual interference and the adverse effect when work betwixt, this location that causes being positioned at the middle part uses the application life of needle bearing very short.Simultaneously, adverse effect on the other hand also shows the distortion that easily causes rotor, thereby has also influenced the application life of motor.
The utility model content
According to above-mentioned situation, the utility model will provide dress plug-in type concrete vibration bar in a kind of improved motor, make it can overcome many weak points of present like product, realization can be reduced in the excessive demand on processing and/or the assembly precision, and can be with the needle roller type location bearing that must adopt in the plain ball bearing present like product of generation, reach and both reduced cost, can solve the various problems such as distortion of rotor again effectively, the purpose that prolongs motor and other corresponding construction parts application life.
The structure of dress plug-in type concrete vibration bar in the improved motor of the utility model, equally by afterbody to the casing of end in the space, prolong axis and be provided with driving mechanism unit that comprises motor stator and rotor and the eccentric whirling vibration unit that is driven by it, rotor and eccentric whirling vibration unit are fixed in the casing in the space through the supporting of at least 3 bearing arrangements, and the electric power connection line of driving mechanism unit is drawn by afterbody.Wherein, this rotor and eccentric whirling vibration unit the absolute construction that is separated from each other for being provided with through corresponding bearing arrangement supporting respectively, and through the facial syndeton that is provided with is in transmission connection in its axial opposite end.Here the facial syndeton that is provided with in said axial opposite end in rotor and eccentric whirling vibration unit, except that two-way plug-type syndeton bodily form formulas such as the at present simple key commonly used of the employing that can be used as concrete enforcement reference example, pin, can also adopt as buckle mutually, wear and the syndeton of other various ways such as helicitic texture.
In said structure, because this rotor and eccentric whirling vibration unit are two absolute construction parts that can be separated from each other, therefore said rotor and eccentric whirling vibration unit can be respectively through being positioned at its bearing arrangement at two ends suitable position place separately, supporting is arranged in the interior space of casing, thus no longer have as in the present like product because of the processing that must adopt in the middle part of this integral form structural member institute and/or assembly precision require all very high location bearing must run into and the problems of need solution.Simultaneously, because between rotor and eccentric whirling vibration unit is interconnective through suitable syndeton, therefore the diameters of its two two axial relative connection ends just can have bigger variation degree of freedom, then can adopt common ball bearing to replace the needle bearing that must use at present according to actual conditions, and required adaptive change gets final product only need make the two two axially relative diameter that are connected the end of rotor and eccentric whirling vibration unit make ball bearing structures satisfied and that it uses separately to cooperate the time.This form of structure is except that can significantly reducing cost, since between rotor and eccentric whirling vibration unit for to interconnect by suitable syndeton, so the no matter processing therebetween and/or the height of assembly precision, therebetween phase mutual interference and adverse effect can be integrally-built form less than the two to some extent when work.
On the basis of said structure, for making arranging and further compact and reasonable being set of each structure member in the casing, as one of alternative optimal way in the specific implementation, be the two bearings structure that makes wherein said rotor and the axial relative connection end side of eccentric whirling vibration unit, be adopted as the form of shared same bearing arrangement.
Be appreciated that thus, dress plug-in type concrete vibration bar in the motor of the above-mentioned improvement form of structure of the utility model, be the rotor of overall structure form and eccentric whirling vibration unit in the like product by having now, two independent structures bodies that the portion connecting structure work is in transmission connection mutually in the warp have been changed into, and by after the corresponding bearing support structure form, can reach the excessive demand that reduces on processing and the assembly precision fully, and can realize with the necessary expensive needle roller type location bearing structure of using in the plain ball bearing present like product of generation, both reduced cost, prolonged its application life, can solve the problems such as distortion of rotor again effectively, the purpose that has prolonged motor and other corresponding construction parts application life.
According to foregoing, under the prerequisite that does not break away from the above-mentioned fundamental technics thought of the utility model,, modification, replacement or the change of various ways can also be arranged to its content according to the ordinary skill knowledge and the customary means of this area.
Below in conjunction with the specific embodiment, foregoing of the present utility model is described in further detail again by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.All technology that is realized based on the utility model foregoing all belong to scope of the present utility model.
