Description
Technical field
The utility model relates to a kind of universal machine accessory, is specifically related to a kind of novel coupler.
Background technique
Between existing most machinery, be provided with various transmission shafts, and the great majority that arrange of transmission shaft have strict NBS, there is dimensionally strict regulation, but there will be the situation that length is inadequate between transmission shaft in the middle of some equipment, so just there has been the existence of coupling.
Coupling is that driving shaft and the driven shaft for connecting in obstructed mechanism makes both carry out the mechanical parts of common rotation, in the power transmission of high-speed overload, it is the effect of dynamic performance that some coupling also has buffering, vibration damping and raising axle, common coupling fixes axle and coupling by place key on driving shaft and driven shaft, make driving shaft drive coupling to rotate, drive driven shaft to rotate by coupling.
But after driving shaft is braked, driven shaft still has certain inertia, driven shaft is under the effect of inertia, can proceed to rotate, but now driving shaft stops operating, the rotation of driven shaft can be subject to the obstruction of driving shaft, now can be to the key effect on driving shaft and transmission shaft, comparatively frequently in situation, can make the impaired situation of key or coupling occur in braking.
Model utility content
Technical problem to be solved in the utility model is the novel coupler that a kind of braking that can effectively relax driven shaft after driving shaft braking is provided for the above-mentioned state of the art.
For achieving the above object, the utility model provides following technological scheme:
A kind of novel coupler, include main shaft coupling portion and the duplicate invoice axial region that is connected driven shaft for connecting driving shaft, described main shaft coupling portion and duplicate invoice axial region are bolted, on described duplicate invoice axial region, be equipped with and wear axle piece for coupling shaft, described wearing on axle piece is provided with ratchet, on described duplicate invoice axial region, the position of corresponding ratchet is provided with steering shaft, described duplicate invoice axial region also includes fixture block, and a side of fixture block is connected with steering shaft, described fixture block is taking steering shaft as axle, rotate in a circumferential direction around steering shaft, the corresponding side being connected with steering shaft of described fixture block is provided with elastic component, and the other end of the corresponding fixture block of elastic component is connected with duplicate invoice axial region.
In main shaft coupling portion, wear driving shaft, on duplicate invoice axial region, place and wear axle piece, to wear axle piece is connected with driven shaft again, then by bolt, main shaft coupling portion is connected with duplicate invoice axial region, completed being connected of this novel coupler and axle, in the time that driving shaft starts to rotate the rotation of drive coupling, duplicate invoice axial region starts to rotate, because only having a side, the fixture block on duplicate invoice axial region is connected with the steering shaft on duplicate invoice axial region, in the time that duplicate invoice axial region rotates, the opposite side that fixture block is corresponding and duplicate invoice axial region is hinged can withstand duplicate invoice axial region, the ratchet of now wearing on axle piece can be blocked by fixture block, cannot rotate, wearing axle piece can rotate in the lump along with duplicate invoice axial region, thereby drive driven shaft to rotate, coupling can be worked normally.
After driving shaft braking, owing to being bolted between main shaft coupling portion and duplicate invoice axial region, and main shaft coupling portion and driving shaft are fixed, inertia when driven shaft can still keep it to rotate after driving shaft braking, can continue to keep former direction to be rotated further, make the now tooth of ratchet to promote fixture block from the hinged opposite side of fixture block, fixture block is rotated, after ratchet turns over a tooth, elastic component can promote fixture block, fixture block is resetted, so carry out reciprocal work, by coordinating of ratchet and fixture block, make driven shaft after driving shaft is braked, driven shaft can also carry out certain rotation, and by the collision between fixture block and ratchet, ratchet is carried out to deceleration progressively, make from all progressively decelerations slowly of axle, avoid after driving shaft braking, driven shaft is but subject to duplicate invoice axial region situation about pullling because the effect of inertia own is rotated further occurs, make driven shaft can carry out stopping again after certain buffering, effectively reduce the warping force being subject on axle, extend the working life of axle.
Of the present utility modelly further be set to, be equipped with the flexible rod being convexly curved in described elastic component, be provided with the telescopic chute of placing for flexible rod on described duplicate invoice axial region, described flexible rod is flexibly connected with flexible rod.
By adopting such scheme, in elastic component, being equipped with the flexible rod being convexly curved, be because the elastic performance of elastic component own is good, and rigidity is poor, by flexible rod is set, can play to elastic component the effect of rigid support, guarantee that elastic component can work normally, flexible rod setting is convexly curved simultaneously, can be convenient to fixture block reclaims flexible rod, and telescopic chute is set on flexible rod, also makes flexible rod can take in the middle of telescopic chute, guaranteed the normal movement of fixture block.
Further, a side of the corresponding telescopic chute of described flexible rod is provided with block.
A side at the corresponding telescopic chute of flexible rod arranges block, can avoid flexible rod in the middle of telescopic chute, to depart from flexible process, guarantee the normal work of flexible rod, made driving shaft fixture block in the process of braking still can keep normal working state in the process of repeatedly motion.
Further, described in wear on axle piece and be provided with swivel becket, on described duplicate invoice axial region, be provided with the rotation slot suitable with swivel becket.
Swivel becket is set wearing on axle piece, and the rotation slot suitable with swivel becket is set on duplicate invoice axial region, can make to wear axle piece in the process of rotating along with driven shaft, can also fit with duplicate invoice axial region firmly, guarantee to wear the normal work of axle piece, simultaneously also can within the time of rotating with inertia, impose resistance to wearing axle piece to wearing axle piece, allow the steady decline of speed of driven shaft.
As concrete technological scheme of the present utility model, described elastic component is spring.
Preferred version using spring as elastic component, is because the elasticity capacity of spring itself is good, can adapt to long-term work, and spring itself is cheap simultaneously, and the manufacture cost of this novel coupler is reduced greatly.
Compared with prior art, the utility model has the advantage of: cooperatively interact by the fixture block on duplicate invoice axial region and the ratchet of wearing on axle piece, make after driving shaft brakes, driven shaft still can rotate along with its inertia, slowly slow down, guarantee that axle can, because damaging appears in frequent braking, not extend the working life of axle.
