Abstract
The utility model relates to a coupling without fastener, comprising an outer sleeve, a driven body formed by a lining which is arranged in the outer sleeve, and a driving body which is formed by that two semicircle centrifugal blocks are clamped with a groove in the center sleeve and in the outer circle groove of the semicircle centrifugal block is provided with an annular spring. The driving body is arranged in the lining of the driven body. The utility model which has the advantages of novel and simple physical design, practicability and weak switch percussion decreases the commutating current of an electric motor, reduces temperature rise of the electric motor, eliminates the vibration of machine, ensures the quality of workpieces and enhances the serviceability rate of machine.
Description
The utility model belongs to mandrel connector and makes the field.
Prior art in the utility model prior art field is: existing linear cutting machine adopts elastic ring column pin shaft coupling and elasticity cross shaped joint coupling more, its deficiency is: reversing impact is very serious, under the reversing impact effect, linking bond is cut off, pin fractures, the cross shaped joint fragmentation, even the fault that transmission shaft (comprising motor shaft) twists off takes place often.
Purpose of design of the present utility model is: avoid deficiency of the prior art, design that a kind of novel structure is simple, reversing impact power is faint and can guarantee (linear cutting machine) reliably not coupling of proper functioning.
Design proposal of the present utility model is: 1, design philosophy: reversing impact is an absolute being, but reversing impact power is little of very far away apart from the strength of materials limit, just do not constitute the destruction to material, the utility model becomes many little imaginations of dashing with a large impact and designs.The utility model is done on the coaxial line, and the usefulness of diaxon connection belongs to the coupling class.Before active part starts and when commutating, be not coupled situation, so, this mechanism is named as " not coupling ".2, purposes: the utility model has replaced elastic ring column pin shaft coupling and cross shaped joint coupling that linear cutting machine uses at present, and it also is applicable to the little torque drive of other high speed.3, organization plan: model utility has active body and by kinetoplast two-part, and can not the transmission active body by kinetoplast.Active body is installed on the driving shaft (as motor shaft) of high speed rotating; Be installed on the driven axle by kinetoplast.Active body is made of central sleeve, centrifugal of semicircle, annular spring; Constituted by overcoat, lining by kinetoplast.Its detailed organization plan is: coupling not, and it comprises overcoat 5, lining 4 is positioned at overcoat 5 and constitutes by kinetoplast; In two semicircle centrifugal 2 grooves that are connected to central sleeve 1 and in two semicircle centrifugal 2 cylindrical draw-in grooves annular spring 3 is housed and constitutes active body, active position is in by the lining of kinetoplast.Central sleeve 1 is to be made of and for one foreground 7 and backstage 9, and the axis bilateral symmetry on foreground distributes perpendicular to the groove 8 of axis, the bottom land wall of two grooves constitutes that two semicircle centrifugal 2 clamping card platforms 10, two are shaped on draw-in groove 11 on semicircle centrifugal and clamping is supporting mutually with the clamping Ka Tai of central sleeve and groove.Two semicircle centrifugal 2 two draw-in grooves 11 after involutory constitute a slotted hole.4, working principle: centrifugal 2 is slided along central sleeve 1 groove under centrifugal action, up to pasting dead lining 4, drives with frictional force and is rotated by kinetoplast.When active body commutated, its rotating speed was zero (moment), and centrifugal 2 is separated with lining 4 in spring 3 effects, at this moment by kinetoplast since the effect of inertial force still in rotation.After the active body commutation, brake extremely gradually by kinetoplast to lining 4 subsides again for centrifugal 2, so that drive by kinetoplast.The performance characteristic of this mechanism of putting it briefly be exactly will commutation " moment " be extended for one " process ".Thereby alleviated reversing impact greatly, protected transmission shaft (comprising motor shaft) and coupling arrangement etc.
The utility model compared with prior art, the one, the structural design novelty is simple, practical; The 2nd, alleviate the commutation load widely, thereby reduced the current of commutation of motor, reduced electric machine temperature rise; The 3rd, eliminated impact, alleviated machine vibration, guaranteed workmanship, the serviceability rate of lathe is improved greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of central sleeve of the present utility model.
Fig. 3 is the structural representation of centrifugal of semicircle of the present utility model.
1～3 pair of the utility model is done with narration in conjunction with the accompanying drawings:
Central sleeve 1, centrifugal 2 of semicircle, lining 4 and overcoat 5 are pressed the prior art processing and fabricating with reference to accompanying drawing and specification the 5th part, square screw 6 outsourcings or external coordinations in the annular spring 3 and six; Install: lining 4 is contained in and is interference fit in the overcoat 5 and constitutes by kinetoplast or lining 4 and be processed as one with overcoat 5, two semicircle centrifugal 2 draw-in grooves 11 are connected on the clamping card platform 10 of central sleeve 1 and annular spring 3 are contained in the two semicircle centrifugal 2 cylindrical draw-in grooves that constituted and constitute active body, active body is contained in promptly constituted the utility model in the lining 4 of kinetoplast, during use, the axis hole of active body (axis hole of central sleeve) is installed on the driving shaft (as motor shaft) of high speed rotating; Be installed on the driven axle by the axis hole of kinetoplast (axis hole of overcoat).
Claims (3)
1, a kind of not coupling, it comprises overcoat 5, it is characterized in that: lining 4 is positioned at overcoat 5 and constitutes by kinetoplast; In two semicircle centrifugal 2 grooves 8 that are connected to central sleeve 1 and in two semicircle centrifugal 2 cylindrical draw-in grooves annular spring 3 is housed and constitutes active body, active position is in by the lining of kinetoplast.
2, not coupling according to claim 1, it is characterized in that: central sleeve 1 is to be made of and for one foreground 7 and backstage 9, and the axis bilateral symmetry on foreground distributes perpendicular to the groove 8 of axis, the bottom land wall of two grooves constitutes that two semicircle centrifugal 2 clamping card platforms 10, two are shaped on draw-in groove 11 on semicircle centrifugal and clamping is supporting mutually with the clamping Ka Tai of central sleeve and groove.
3, not coupling according to claim 1 and 2 is characterized in that: two semicircle centrifugal 2 two draw-in grooves 11 after involutory constitute a slotted hole.
