The integral type outer rotor motor end cover has a simple structure, and is convenient to install, not only the installation accuracy of the end cover is improved, but also the problem of concentricity is avoided, and the practical value of the integral outer rotor motor is greatly improved.
Description
Technical field
The utility model relates to a kind of integral type outer rotor motor, specifically, relates to a kind of integral type outer rotor motor end cap.
Background technology
At present, the external rotor asynchronous machine of known integral type end cap mainly is a low-power machine, and power is no more than 1KW, and what the whole external rotor electric machine end cap of high-power (power is from 1KW to 15KW) adopted is that bolt and seam assemble.This connected mode of powerful whole external rotor electric machine end cap makes it morpheme sum of errors rigging error may occur in processing and fit on owing to increased bolt and seam.The appearance of row bit error and rigging error, may bring following subject matter:
One. in case processing and assemble not in placely, with the air gap inequality that is easy to cause between electric motor end cap and the miscellaneous part, cause motor to damage because of the mutual friction of rotor phase;
Two. easily cause motor to produce electromagnetic noise and vibration, motor properties is degenerated owing to air gap is uneven;
Three. if use bolt to assemble, because bolt must bear the vibration in using of the weight of motor integral body and motor, so bolt is easy to become flexible, and causes motor to damage;
Four. because increasing of processing component make the work efficiency of motor reduce, but processing cost but increases to some extent.
The utility model content
The purpose of this utility model is to provide a kind of integral type outer rotor motor end cap, solves problems of the prior art, reaches the assembly process of simplifying motor and the purpose that improves assembly precision.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Integral type outer rotor motor end cap comprises the end cap shelves, and with the fuse shelves unshakable in one's determination of structure of this end cap shelves inwall center, these iron core shelves are hollow structure, and are respectively arranged with bearing chamber at these iron core shelves two ends.
Further, described end cap shelves, shelves unshakable in one's determination, bearing chamber three's axis is same straight line; And described shelves unshakable in one's determination with its on the end cap shelves to be connected end face vertical.Axis by control end cap shelves, shelves unshakable in one's determination, bearing chamber three is effectively guaranteed the concentricity of whole electric motor end cap.
Further, described shelves unshakable in one's determination and the junction of end cap shelves also are provided with the reinforcement that is connected iron core grade and end cap shelves.Reinforcement forms firm triangular structure with shelves unshakable in one's determination, end cap shelves, and the fastness between shelves unshakable in one's determination and the end cap shelves is improved greatly.
Again further, described end cap shelves and shelves unshakable in one's determination are by die casting or pour into a mould one-body molded.
Compared with prior art, the utlity model has following beneficial effect:
1. electric motor end cap makes end cap shelves and shelves unshakable in one's determination form integrative-structure, thereby has simplified the procedure of end cap greatly by die casting or pouring one-step forming in the utility model, makes the assembling of motor simpler.
2. the utility model need not bolt have promptly been realized the connection between each parts of electric motor end cap, and the morpheme sum of errors rigging error of effectively having avoided prior art to exist has improved the precision of motor assembling.
3. the end cap shelves are the concentric integrative-structure of cylindrical with shelves unshakable in one's determination, bearing chamber in the utility model, the concentricity that need not other workpieces can guarantee end cap, and then the concentricity of motor integral body is effectively guaranteed, thoroughly solved the concentricity problem of integral type outer rotor motor.
4. not use bolt to carry out fastening for the utility model, both reduced product cost, reduced assembly process again, and motor performance is not affected, and therefore, the cost performance of integral type outer rotor motor improves greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is installed on assembling schematic diagram on the motor for the utility model.
The title of correspondence in the accompanying drawing: 1-end cap shelves, 2-shelves unshakable in one's determination, 3-bearing chamber, 4-reinforcement, 6-bearing, 7-axle collar, 8-iron core, 9-rotor, 10-mandrel.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and execution mode of the present utility model includes but not limited to following embodiment.
Embodiment
As shown in Figure 1, integral type outer rotor motor end cap mainly comprises end cap shelves 1 and shelves 2 unshakable in one's determination, and the center of an end of these iron core shelves 2 and end cap shelves 1 inner surface is connected as a single entity, and shelves 2 unshakable in one's determination are 90 ° with the angle that end cap shelves 1 form; Two ends at shelves 2 unshakable in one's determination are respectively arranged with a bearing chamber 3, are used to install bearing 6; Simultaneously, in order to guarantee the concentricity of end cap, the axis of end cap shelves 1, shelves 2 unshakable in one's determination, bearing chamber 3 is same straight line, because the three is the integrative-structure by die casting or pouring one-step forming, therefore, the concentricity of end cap is not subjected to influence of mounting accuracy, as long as end cap does not damage, just will there be error in its concentricity.
In order to improve the stability of end cap, have additional reinforcement 4 in the junction of end cap shelves 1 and iron core shelves 2, the triangle of reinforcement 4 and end cap shelves 1, a fixed in shape of unshakable in one's determination grade 2 formation, thus the resistance to overturning of end cap is effectively guaranteed.So far, whole end cap just becomes the fixing global facility of a structure, himself no longer be subject to processing or the influence of assembly precision, on being installed on motor after, can improve the overall performance of motor, the problem of effectively avoiding prior art to exist greatly.
The assembling schematic diagram of above-mentioned end cap on motor as shown in Figure 2, the assembly relation of itself and motor miscellaneous part is as follows:
The shelves 2 unshakable in one's determination of end cap are placed on the mandrel 10 fully, mandrel 10 two ends extend into respectively in two bearing chambers 3, and there is the gap between the inwall of mandrel 10 and bearing chamber 3, the bearing 6 of mounting strap endoporus in this gap, iron core 8 press-fits on shelves 2 unshakable in one's determination, the endoporus of bearing 6 is then passed in the rotating shaft of rotor 9, and uses axle will ly to fix with collar 7.
In the foregoing, end cap integral body is "T"-shaped, and wherein, end cap shelves 1 are meant the carrier of end cap miscellaneous part, and it is vertical with unshakable in one's determination grade 2; Shelves 2 unshakable in one's determination are the open circles tubular of both ends open, are mainly used in carrying iron core 8, and socket mandrel 10; Iron core 8 then is the iron core of band winding.
