The AC compact type motor frame structure provided by the utility model can reduce the dead weight of the motor and the cost of the motor, effectively reduce temperature rise of the motor and the adverse effects of welding operation to the size of spigots on two sides of the frame, enhance the precision of the motor, prolong the service life of the motor, and reduce the noise of the motor and vibration indexes.
Description
Technical field
The utility model relates to machine field, relates in particular to a kind of interchange compact(ing) machine stand structure.
Background technology
The technology that traditional alternating current machine adopts is earlier the stator punching closed assembly to be become iron core, and then iron core integral body is pressed into the support of integral type, because integral type support surface radiating is the main cooling channel of enclosed motor, secondly, the intensity of support must be guaranteed, thereby exists a series of problems such as the support volume is big, surface texture is complicated, material therefor is more, radiating effect is relatively poor.In addition, when being tested, compact(ing) machine finds that motor oscillating and noise are bigger than normal, find that after testing all there is the distortion situation in support both sides seam, ultimate analysis draw reason be stress that the thin wall-type shell structure at support two ends the time is gathered in welding effectively do not discharge cause, this situation can shorten the life-span of motor bearings, increases the maintenance cost of motor.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art and a kind of interchange compact(ing) machine stand structure is provided, it can alleviate the deadweight of motor, reduce the cost of motor, effectively reduce electric machine temperature rise, and reduce the adverse effect of welding operation to support both sides seam size, increase the accuracy of motor, prolong the useful life of motor, reduce the noise and the vibration index of motor.
The technical scheme that realizes above-mentioned purpose is: a kind of interchange compact(ing) machine stand structure, comprise stator core and housing, wherein,
It is square cuboid that described stator core is the cross section, it is formed by some identical punching closed assemblies, this stator core inside in axial direction is provided with several air ducts, weld four angle steel respectively on its four ribs, and also be welded with band steel on its peripheric surface so that some punchings form an integral body;
Described housing comprises first housing and second housing that is welded in described stator core both sides.
Above-mentioned interchange compact(ing) machine stand structure wherein, is evenly equipped with several ventilation holes in the described punching, formed described axial ventilation road behind their process punching closed assemblies.
Above-mentioned interchange compact(ing) machine stand structure, wherein, the ventilation hole in the described punching is shaped as circle.
The beneficial effects of the utility model are: the utility model alleviates the deadweight of motor by the application of stacked support, reduces the cost of motor; By the setting of base inner wind path, reach the effect of effective reduction electric machine temperature rise; By the structure applications of syllogic support, reduce the adverse effect of welding operation to support both sides seam size, increase the accuracy of motor, prolong the useful life of motor, reduce the noise and the vibration index of motor.
Description of drawings
Fig. 1 is the structural representation of interchange compact(ing) machine stand structure of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, there is shown a kind of interchange compact(ing) machine stand structure of the present utility model, comprise stator core 1 and housing, wherein:
It is square cuboid that stator core 1 is the cross section, it is formed by some identical punching 11 closed assemblies, this stator core 1 inside in axial direction is provided with several air ducts 4, weld four angle steel 3 respectively on its four ribs, and also be welded with band steel 2 on its peripheric surface so that some punchings 11 form an integral body;
Housing comprises that first housing 5 that is welded in stator core 1 both sides and second housing, 6, the first housings 5 and second housing 6 are a kind of thin wall-type frame structures, is mainly used in the installation of both sides end cap, the protection of winding overhang etc.;
Be evenly equipped with several circular ventilation holes 41 in the punching 11, form air duct 4 behind their process punching 11 closed assemblies.
The utility model is stacked support, stator core 1 is the main place that the motor magnetic circuit distributes, by punching 11 closed assemblies, pressurization is formed, then by being distributed in several groups of band steels 2 of punching 11 four sides and four jiaos, the welding of angle steel 3, formed an integral body reliably, be shaped on several groups of circular ventilation holes 41 in 11 4 jiaos of upper punches of punching, behind closed assembly, just formed axial air duct 4 naturally in stator core 1 inside, because punching 11 is that welding is fixing under the situation of pressurization, be similar to and think that this air duct 4 seals, the enclosed-ventilated road 4 of stator core 1 inside can effectively improve cooling effectiveness, thereby improve the output torque of unit volume motor, the material of saving motor uses.In addition, after preventing the integral type welding, two side body seam equidimensions produce moderate finite deformation, so earlier first housing 5 and second housing 6 are welded as individual components respectively, carry out temper then, discharge stress wherein, again itself and stator core 1 are welded at last, it is minimum that stress in two side bodies has been dropped to, and the precision when guaranteeing the motor assembling prolongs useful life of motor.
This stand structure is applicable to the interchange compact(ing) machine, the characteristics of this type motor are small sizes, export torque greatly, because the wind path characteristics and the punching of this support directly are exposed in the air, so the degree of protection of the type motor can only reach IP23, generally be applicable to indoor environment or the outdoor environment of waterproof measure arranged that the type of cooling is the cooling of IC06 high wind.
In sum, the utility model is the characteristics at compact and open-type electric machine, carried out the improvement of wind path, the closed cooling air channel that promptly is used for the cooling air circulation core interior being provided with, the support of cancellation integral type under the situation that guarantees electric machine stand intensity, reach the minimizing material, reduce the purpose of motor cost; In addition, the syllogic support has improved the performance index of noise of motor and vibration aspect, has prolonged the useful life of motor.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.
