Abstract
The utility model relates to a motor pulley being convenient to assemble and disassemble. The motor pulley comprises a key bar, a motor axle, screws, an aperture tapered sleeve and a pulley body, wherein the outer tapered face of the aperture tapered sleeve is positioned in the tapered hole of the pulley body; the aperture tapered sleeve sleeves the motor axle; the key bar is positioned in a key groove of the aperture tapered sleeve and the motor axle; and the aperture tapered sleeve and the pulley body are integrally connected by the screws. When the pulley is installed, the screws are fastened to tightly press the aperture tapered sleeve into the tapered hole of the pulley body so that the inner diameter of the aperture tapered sleeve is narrowed to be matched with the motor axle; and when the pulley is detached, the screws are detached firstly to make the inner diameter of the aperture tapered sleeve be increased and make the aperture tapered sleeve and the motor axle be released so that the pulley body can be taken off from the motor axle. The motor pulley can be assembled and disassembled without being beaten by an iron hammer so that the time and labor are saved and the motor pulley is not damaged. Therefore, the motor pulley being convenient to assemble and disassemble has evident social and economical effects.
Description
Technical field
The utility model is motor pulley, is just assembling/disassembling type motor pulley of one.
Background technique
Existing motor pulley mounting and dismounting method is all to use iron hammer to beat belt pulley exterior edge face, motor pulley is packed on motor shaft, or disassemble from motor shaft.This mounting and dismounting method easily damages belt pulley, and iron hammer beats that power is large, and operator is dangerous, and labor intensity is large, and the time that completes installment work is long, and motor idle time is long, and load business is produced, and affects output.Chinese patent 200720025488.9 " just assembling/disassembling type motor pulley ", time saving and energy saving in the time of mounted motor belt pulley, do not damage motor pulley.But because the taper hole of open conical sleeve male cone (strobilus masculinus) and belt pulley produces self-locking sometimes, open conical sleeve is not easy to take out, make its dismounting inconvenient.
Summary of the invention
The purpose of this utility model is just assembling/disassembling type motor pulley of design one, makes its motor pulley for convenience detach.
The purpose of this utility model is achieved in that and comprises screw, key bar, open conical sleeve, motor shaft, belt pulley, open conical sleeve is put in the taper hole of belt pulley, open conical sleeve is enclosed within on motor shaft, key bar is put in the keyway of open conical sleeve and motor shaft, screw links into an integrated entity open conical sleeve and belt pulley, on the outside thread of screw, configure nut, the outside of nut in belt pulley is also close to the inner side end of open conical sleeve.
The beneficial effects of the utility model are: when dismounting motor pulley reversion screw, screw exits on belt pulley, and while exiting, nut is together walked, and drives open conical sleeve outwards to walk, thereby is disassembled easily.
Brief description of the drawings
Fig. 1 is plan view of the present utility model.
Fig. 2 is side view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in the figure, embodiment of the present utility model comprises screw 1, key bar 3, open conical sleeve 4, motor shaft 5, belt pulley 6, open conical sleeve 4 is put in the taper hole of belt pulley 6, open conical sleeve 4 is enclosed within on motor shaft 5, key bar 3 is put in the keyway of open conical sleeve 4 and motor shaft 5, screw 1 links into an integrated entity open conical sleeve 4 and belt pulley 6, on the outside thread of screw 1, configure nut 2, make nut 2 and screw 1 integral, the outside of nut 2 in belt pulley 6 is also close to the inner side end of open conical sleeve 4.
When belt pulley 6 is installed, fastening screw nail 1 is tightly pressed into open conical sleeve 4 in the taper hole of belt pulley 6, open conical sleeve 4 internal diameters are dwindled and realize and the coordinating of motor shaft 5, when dismounting belt pulley 6, screw 1 reverses, screw 1 moves back and buckles with the connecting thread of belt pulley 6, screw 1 is outwards walked, and drives nut 2 to walk simultaneously, and nut 2 promotes open conical sleeve 4 and outwards walks, make its open conical sleeve 4 depart from belt pulley 6, realize belt pulley 6 for convenience detach.
