Abstract
The utility model discloses an anti-rotation structure of a traction machine stator with a winding. The anti-rotation structure comprises a stator with a winding and a machine pedestal, and also comprises a semicircular flat key. The semicircular flat key comprises a flat key segment and a circular pin segment. The stator is in clamp connection with the flat key segment, and the circular pin segment is clamped in a semicircular pin hole of the machine pedestal. The semicircular flat key integrates the functions of a circular pin and a flat key by employing a conventional flat key mode on the stator and a circular pin mode on the machine pedestal, so that it is more convenient for the stator to process a key groove and for the machine pedestal to process the semicircular pin hole at the same time. Meanwhile, the required shear strength is achieved, so that rotation of the stator can be effectively prevented, and it is safer and easier to process and assemble the stator and the machine pedestal of a traction machine under the same conditions.
Description
Technical field
The utility model relates to a kind of permanent-magnet synchnorous gearless dragging machine that is applied in the towed elevator system advantages such as efficient, low energy consumption, environmental protection, and particularly a kind of traction machine has winding stator anti-rotation structure.
Background technology
The elevator place that permanent-magnet synchnorous gearless dragging machine is used in low-speed heave-load, starting torque is large and the positive and negative rotation frequency is high of using at present, just because of this use occasion, during the traction machine operation, by three-phase alternating-current supply, there iing the winding stator to form a rotating magnetic field, there is the magnetic field that can be rotated field drives in rotor with permanent magnet, rotor can form the rotating speed identical with rotating magnetic field like this, and large torque is provided simultaneously.Once owing to there being the winding stator to rotate, corresponding change occurs in whole rotating magnetic field, encoder feedback in frequency converter position of magnetic pole also change, cause the control system of elevator to break down, elevator can not normally move, so there is the anti-rotation structure of winding stator just to seem extremely important.
The anti-rotation structure that winding stator and support are arranged of the external rotor cantilever type permanent-magnet synchnorous gearless dragging machine of current domestic use is generally limit screw and two kinds of modes of flat key.Limit screw, because the rotation shearing force can bear is smaller, can't meet and drag the operating shearing force that the winding stator is arranged of machine machine, and the situation that limit screw is cut off often occurs, and few people use this structure on traction machine now; Current domestic use flat key structure is commonplace, there is like this keyway processing on the winding stator more convenient, but the processing of the keyway on support is cumbersome, generally to separately increase by a procedure, the processing of use slotting machine, efficiency is lower than effect, considers the convenience of support processing in order to improve the traction machine reliability of operation simultaneously, must design that a kind of use is reliable, easy to process winding stator anti-rotation structure mode efficiently.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of traction machine that winding stator anti-rotation structure is arranged, and to prevent more reliably the rotation of winding stator, and cuts down finished cost.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of traction machine has winding stator anti-rotation structure, includes winding stator and support, also comprises a semicircle flat key; Described semicircle flat key comprises flat key section and round pin section, and described have winding stator and a described flat key section engagement connection, and described round pin section snaps in the semi-circle pin holes of described support.
Preferably, the described flat key section of described semicircle flat key and round pin section are integrated and process, and the diameter of section of described round pin section is greater than the cross-sectional length of described flat key section.
Pass through technique scheme, the traction machine that the utility model provides has winding stator anti-rotation structure, its semicircle flat key combines the function of round pin and flat key, the mode that adopts original flat key on the winding stator is being arranged, adopt the mode of round pin on support, there is like this winding stator processing keyway more convenient, the semi-circle pin holes of support processing simultaneously also than efficacious prescriptions just, meet again its shearing strength simultaneously, can effectively prevent the rotation of winding stator, make under the processing that winding stator and support are arranged of traction machine and assembling aspect equal conditions safer, convenient.
The accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, in below describing embodiment, the accompanying drawing of required use is briefly described.
Fig. 1 is that the disclosed traction machine of embodiment has winding stator anti-rotation structure schematic diagram;
The perspective view that Fig. 2 is the disclosed semicircle flat key of embodiment.
Numeral in figure:
11. winding stator 12. support 13. semicircle flat keys are arranged
21. flat key section 22. round pin sections
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
With reference to figure 1 and 2, the traction machine that the utility model provides has winding stator anti-rotation structure, includes winding stator 11 and support 12, also comprises a semicircle flat key 13; Semicircle flat key 13 comprises flat key section 21 and round pin section 22, and winding stator 11 and flat key section 21 engagement connections are arranged, and round pin section 22 snaps in the semi-circle pin holes of described support 12.
Wherein, flat key section 21 and the round pin section 22 of semicircle flat key 13 are integrated and process, and the diameter of section of round pin section 22 is greater than the cross-sectional length of flat key section 21.
The utility model adopts the mode of semicircle flat key 13, is about to semicircle flat key 13 and first is assembled in the semi-circle pin holes of support 12, then will have winding stator 11 to be inserted in along the direction of flat key section 21, finally will have winding stator 11 to be seated.Due to the flat key section 21 of semicircle flat key 13 that had winding stator 11 to connect, support 12 has connected the round pin section 22 of semicircle flat key 13, the three is unified into an integral body like this, can effectively prevent that winding stator 11 from rotating under the effect of rotating magnetic field, the effect of effect and flat key is just the same, facilitated the processing that winding stator 11 and support 12 are arranged, be a kind of use structure of traction machine and optimal design of processing technology of combining simultaneously.
Wherein, winding stator 11 is arranged for square keyway, generally adopt broaching tool processing, convenient and swift, be suitable for batch production; Support 12 adopts semi-circle pin holes, generally adds disposable processing when man-hour, the work in-process heart was processed other position, hole, without more exchange device processing; Semicircle flat key 13 in Fig. 2 is the synthesis of round pin and flat key, more convenient at the aspects such as assembling of traction machine.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.Multiple modification to above-described embodiment will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
