Embodiment
For the effect that makes technological means of the present utility model and can reach, can have more complete and clearly disclose, be hereby described in detail as follows, see also accompanying drawing and the figure number of exposure:
First, refer to shown in Fig. 1, for motor linking shaft cent(e)ring ring of the present utility model, this cent(e)ring ring 3 comprises a ring main body 31, and form an annular distance 311 in these ring main body 31 central authorities, and these ring main body 31 materials wear-resisting material such as be Furtulon, and make ring main body 31 outer periphery 312 form convex arc-shape, the annular distance wall 313 of another ring main body 31 forms flat, an end face in this ring main body 31 is concaved with along the groove 32 of these ring main body 31 moulding again, and make this ring main body 31 be provided with otch 33 in a side place, so that this ring main body 31 forms and disconnects shape in these otch 33 places.
Accordingly, when assembling is used, refer to shown in Fig. 1~figure tetra-, the otch 33 that its ring main body 31 1 sides of cent(e)ring ring 3 mats of the present utility model are disconnected, and large its ring footpath of support, make the annular distance 311 of cent(e)ring ring 3 its ring main bodys 31 of the present utility model can convenient be sheathed on embedding ditch default on machinery equipment 2 its main shafts 21 22 location, utilize ring main body 31 its annular distance walls 313 to form flat design simultaneously, to reach in the interior good location effect of embedding ditch 22, again machinery equipment 2 main shafts 21 that are arranged with this cent(e)ring ring 3 are inserted in the appearance hole 12 of direct-drive motor 1 its transmission shaft 11, now, cent(e)ring ring 3 of the present utility model offsets and contacts with appearance hole 12 hole walls of transmission shaft 11, and utilize cent(e)ring ring 3 its grooves 32 to design, can make cent(e)ring ring 3 be and there is elasticity and flexible allowance, so, just can to proofread and correct machinery equipment 2 its main shafts 21, be sheathed on direct-drive motor 1 its transmission shaft 11Rong Kong 12 rear center's departures via cent(e)ring ring 3, and the main shaft 21 of machinery equipment 2 is aligned with direct-drive motor 1 its transmission shaft 11 centers, in this, thereby reach while reducing direct-drive motor 1 drive machinery equipment 2 main shafts 21 rotation, the phenomenon such as when dynamic start moment pause and transition in rhythm or melody vibrations and start, rock, to guarantee power transmission smooth degree and validity, and make a noise while reducing transmission, thereby improve the working life of direct-drive motor 1 and machinery equipment 2.
And rotate when direct-drive motor 1 drives machinery equipment 2 main shafts 21, via cent(e)ring ring 3, eliminate its vibrations and rock and make the suffered extruding force of used time cent(e)ring ring 3, can utilize its groove 32 to make cent(e)ring ring 3 bufferings, absorb this extruding force, so that cent(e)ring ring 3 is being subject under frequent extruding, also can maintain for a long time distortion and not damage effect, another via 3 settings by wear-resisting material formings such as Furtulons of cent(e)ring ring, also can avoid frequently the rubbing situation of the wearing and tearing that cause, thereby reach, make cent(e)ring ring 3 of the present utility model there is the effect of long-acting use, and then avoid just 3 maintenances of cent(e)ring ring being renewed every the short time, the cost allowance causing, and frequent maintenance is shut down, the situations such as the delay in man-hour causing and manufacturing efficiency reduction.
Aforesaid embodiment or accompanying drawing are not implemented sample state in order to limit motor linking shaft cent(e)ring ring of the present utility model, under all, in technical field, there is suitable variation or the modification of conventionally knowing that the knowledgeable does, all should be considered as not departing from motor linking shaft cent(e)ring ring patent category of the present utility model.
From said structure and mode of execution, the utlity model has following advantage:
1. motor linking shaft cent(e)ring ring of the present utility model is concaved with along the groove of this ring main body moulding its ring main body one end face, so that cent(e)ring ring has elasticity and flexible allowance, by this, when center correcting collar, eliminating direct-drive motor drives machinery equipment main shaft rotate the vibrations that produce and rock effect, and while being subject to frequently pushing, to utilize this groove be available buffer, absorb extruding force, to reach, makes cent(e)ring ring maintain for a long time distortion not damage effect.
2. motor linking shaft cent(e)ring ring of the present utility model makes its ring main body with wear-resisting material formings such as Furtulons, in this, just can further avoid the situation of cent(e)ring ring wearing and tearing that cause when frequent friction.
