Abstract
The invention belongs to the technical field of motors, and relates to a device which prevents a rotating shaft from rotating in the transportation process of the motor in a three-phase asynchronous motor, in particular to a rotating shaft fixing device of the three-phase asynchronous motor. The rotating shaft fixing device comprises a bearing outer cover which is sealed on the end portion of the motor, a motor rotating shaft penetrates out from a center circular hole of the bearing outer cover, the two ends of the diameter direction of the bearing outer cover are respectively provided with a threaded hole, a stud is connected into each threaded hole in a threaded mode, the other ends of the studs are fixedly connected with a shaft clamping plate, and the center of the shaft clamping plate is connected to the rotating shaft through a bolt in a fastening mode. The rotating shaft fixing device of the three-phase asynchronous motor is simple and reasonable in structure, few in part, convenient to assemble and firm in fixing. In practice, any assembling mode of an existing motor is not needed in the rotating shaft fixing device, and the motor rotating shaft can be firmly fixed conveniently only through the fact that the two threaded holes are formed in the bearing outer cover.
Description
Technical field
The invention belongs to the motor technology field, relate to and a kind ofly for threephase asynchronous, prevent the device that motor rotates at the transportation shaft, specifically a kind of threephase asynchronous rotating shaft fixture.
Background technology
Since China joined WTO, the trade contacts of home and overseas are more and more frequent, each other the cooperation at the aspect such as scientific and technological, industrial is also more and more extensive, and threephase asynchronous is as the driving source in science and technology, industrial production, the quantity of producing and exporting is also more and more, and the distance of transportation is also more and more far away.Yet motor shaft, in transportation, often occurs and rotates voluntarily and then cause some rotational components such as motor reel, bearing the phenomenon of damaging to occur in threephase asynchronous, thereby even cause whole motor to run well, scraps.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of a kind of threephase asynchronous rotating shaft fixture simple in structure, ingenious, rational is provided, and this fixture can effectively prevent that motor from the situation that main shaft rotates occurring in transportation.
According to technical scheme provided by the invention: a kind of threephase asynchronous rotating shaft fixture, be characterised in that: comprise the bearing end cover that is covered in the motor end, machine shaft passes from the bearing end cover center hole, a screwed hole is offered respectively at described bearing end cover diametric(al) two ends, a stud all is threaded in each screwed hole, described stud other end fixed connection shaft clamp, and the center of axle clamp is bolted connection in rotating shaft.
As a further improvement on the present invention, described axle clamp is rectangular faceplate, and panel two ends symmetry is offered mounting hole, the stud anterior end penetrates in mounting hole, and fix by nut check, circular hole is offered at described axle clamp middle part, and bolt is fixed in the axle clamp in rotating shaft by this circular hole.
As a further improvement on the present invention, the junction of described bearing end cover outer face and main shaft is provided with sealing ring.
The present invention compared with prior art, advantage is: the present invention is simple and reasonable for structure, parts are few, easy to assembly and fixed, in fact, the present invention is without any assembling mode of existing motor, only, by two screwed holes of processing on bearing end cover, just can realize more easily the firm of motor rotary shaft fixed.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The structural representation that Fig. 2 is Fig. 1 axis clamp.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1 and Figure 2, comprise stud 1, nut 2, bolt 3, axle clamp 4, rotating shaft 5, bearing end cover 6, mounting hole 7, sealing ring 8 etc.
As shown in Figure 1 and Figure 2, the present invention is a kind of threephase asynchronous rotating shaft fixture, comprise the bearing end cover 6 that is covered in the motor end, machine shaft 5 passes from bearing end cover 6 center holes, a screwed hole is offered respectively at described bearing end cover 6 diametric(al) two ends, the stud 1 that all is threaded in each screwed hole, described stud 1 other end fixed connection shaft clamp 4, and the center of axle clamp 4 is fastenedly connected in rotating shaft 5 by bolt 3.
Described axle clamp 4 is rectangular faceplate, panel two ends symmetry is offered mounting hole 7, and stud 1 anterior end penetrates in mounting hole 7, and is locked by nut 2, circular hole is offered at described axle clamp 4 middle parts, and bolt 3 is fixed in axle clamp 4 in rotating shaft 5 by this circular hole.
The junction of described bearing end cover 6 outer faces and main shaft 5 is provided with sealing ring 8.
Operation principle of the present invention is as follows: on the bearing end cover 6 of existing motor, symmetry processes two screwed holes, choose or make by oneself two studs 1 with reference to the sized data of screwed hole, and stud 1 one ends are fastenedly connected on screwed hole, the length that the length of stud 1 is stretched out bearing end cover 6 according to rotating shaft 5 is selected coupling, and then rectangular axle clamp 4 correspondences are installed on to the anterior end of stud 1, and by bolt 3, axle clamp 4 middle parts are fixedly connected in rotating shaft 5, effectively that rotating shaft 5 is fixing by above-mentioned measure, guarantee that motor is in transportation, rotating shaft 5 can not rotate.
The present invention is simple and reasonable for structure, parts are few, easy to assembly and fixed, and in fact, the present invention is without any assembling mode of existing motor, only, by two screwed holes of processing on bearing end cover, just can realize more easily the firm of motor rotary shaft fixed.
