Description

Motor linking shaft cent(e)ring ring

Technical field

The utility model is relevant for a kind of motor linking shaft cent(e)ring ring, espespecially a kind of with wear-resisting and resistance to extruding and can be for long-acting motor linking shaft cent(e)ring ring.

Background technique

Existing as machinery equipments such as sewing machines, mostly adopt direct-drive motor to carry out transmission, though direct-drive motor has, assembling is convenient, cost is low, transmission efficiency high, but, when direct-drive motor is assembled in to the bodies such as sewing machine, often find the out-of-flatness due to body wall, while causing direct-drive motor laminating to be assembled in body wall, the center transmission shaft of direct-drive motor is understood because of the out-of-flatness of body wall, and produces a little error.

In order to revise these errors, on the main shaft of machinery equipment, conventionally can be arranged with rubber washer, while socket-connecting with the transmission shaft of the main shaft in this machinery equipment and direct-drive motor, via this rubber washer, departure buffering between the transmission shaft of its main shaft of machinery equipment and direct-drive motor is eliminated, make the center transmission shaft of direct-drive motor be able to proofread and correct with the alignment of shafts of machinery equipment, and be held on same center line, when significantly reducing power transmission, the shaking phenomenon producing because of departure, the moment pause and transition in rhythm or melody vibrations that produce in the time of also can avoiding dynamic start, to guarantee smooth degree and the validity of power transmission, during with minimizing transmission, make a noise, and improve the machinery equipment texts in working life that direct-drive motor and transmission group thereof connect.But; this rubber washer is owing to being squeezed continually between the main shaft of the transmission shaft at direct-drive motor and machinery equipment and friction etc., causes the easily abrasion and damaging of this rubber washer, and loses its effect such as eliminate that departure and buffering are rocked; therefore on practice is used; every a short time, just must keep in repair, the rubber washer that these abrasion are damaged renews, so; not only cause the raising of maintenance cost; meanwhile, frequent maintenance is shut down, and also can cause delay in man-hour and manufacturing efficiency etc. to reduce disappearance.

Therefore, the inventor is because the rubber washer of the existing transmission shaft for direct-drive motor and its main shaft connecting part of machinery equipment, abrasion easily occur to be damaged, must often keep in repair and the disappearance such as renew, be mat its for many years in the manufacture of association area and assisting a ruler in governing a country of design experiences and knowledge, and through clever thought in many ways, and grind, create the utility model.

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.

3. motor linking shaft cent(e)ring ring of the present utility model makes its ring main body be provided with otch in a side place, so that this ring main body forms and disconnects shape in this incision, so, can make its ring footpath of cent(e)ring ring there is modulability, to be applicable to the main shaft socket of various machinery equipments, use.
