Abstract
The utility model belongs to the motor technology field, relates to a device used to prevent a rotating shaft of a motor from rotating in a three-phase asynchronous motor during a transportation process and especially relates to a three-phase asynchronous motor rotating shaft fixing device. The device comprises a bearing outer cover which carries out seal capping on a motor end portion. The motor rotating shaft passes through a center hole of the bearing outer cover. Two ends of a diameter direction of the bearing outer cover are provided with threaded hole respectively. Each threaded hole forms threaded connection with one double-end bolt. The other end of the double-end bolt is fixedly connected with a shaft clamping plate. A center of the shaft clamping plate is fastened and connected to the rotating shaft through the bolt. The structure of the device of the utility model is simple and reasonable. There are few parts. Assembling is convenient and fixing is firm. Actually, by using the device of the utility model, any assembling modes of an existing motor are not needed; only through processing the two screwed holes on the bearing outer cover, firm fixing of the motor rotating shaft can be conveniently realized.
Description
Technical field
The utility model belongs to motor technology field, relates to a kind ofly for threephase asynchronous, preventing the device that motor rotates at 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 also more and more extensive in the cooperation of the aspect such as scientific and technological, industrial, 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 in transportation, often there is motor shaft and rotate voluntarily and then cause some rotational components such as motor reel, bearing to occur the phenomenon of damaging in threephase asynchronous, thereby even cause whole motor to run well, scraps.
Summary of the invention
The purpose of this utility model 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.
The technical scheme providing according to the utility model: a kind of threephase asynchronous rotating shaft fixture, be characterised in that: comprise the bearing end cover that is covered in motor end, machine shaft passes from bearing end cover center hole, a screwed hole is offered respectively at described bearing end cover diametric(al) two ends, a stud is all 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 further improvement of the utility model, described axle clamp is rectangular faceplate, panel two ends symmetry is offered mounting hole, 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 on axle clamp in rotating shaft by this circular hole.
As further improvement of the utility model, the junction of described bearing end cover outer face and main shaft is provided with sealing ring.
The utility model compared with prior art, advantage is: the utility model is simple and reasonable for structure, parts are few, easy to assembly and fixed, in fact, the utility model is without any assembling mode of existing motor, only, by process two screwed holes on bearing end cover, just can realize more easily the firm of motor rotary shaft fixed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of Fig. 1 axis clamp.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
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 utility model is a kind of threephase asynchronous rotating shaft fixture, comprise the bearing end cover 6 that is covered in 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 is all 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 on 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.
The utility model operation principle is as follows: on the bearing end cover 6 of existing motor, symmetry processes two screwed holes, with reference to the sized data of screwed hole, choose or make by oneself two studs 1, and stud 1 one end is 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 utility model is simple and reasonable for structure, parts are few, easy to assembly and fixed, and in fact, the utility model is without any assembling mode of existing motor, only, by process two screwed holes on bearing end cover, just can realize more easily the firm of motor rotary shaft fixed.
