Abstract
The utility model relates to a coupling. The coupling is provided to overcome equipment damage caused by high-speed operation and unavailable axis coincidence during use of the present coupling. The coupling is an integrated cylinder, wherein two ends of the cylinder are respectively provided with a groove for installing a driving shaft and a driven shaft which are fixed with the corresponding grooves through a fastening screw. With the coupling, not only can parts be prevented from falling off, but also a mechanical axis coincides to an inertia axis, the normal operation of machinery is ensured and the service life of equipment is prolonged.
Description
Technical field
The utility model relates to a kind of mechanical parts, relates in particular to a kind of coupling.
Background technique
Coupling is that two axles (driving shaft and driven shaft) that are used for connecting in the different institutions make it the mechanical parts of common rotation with transmitting torque.Traditional coupling is two individual components that link together, and that is to say, is made of coupling that connects driving shaft and driven axle respectively and the connection part that is positioned in the middle of two coupling.When motor drove driving shaft and driven axle high speed rotating, the fastening screw that is used for fixing came off, and causes device damage.Simultaneously, because the axis of coupling is artificial involutory, so will produce the phenomenon of uneven centrifugal inertia force, centrifugal inertia idol power and dynamic deflection (vibration shape) in the running, this energy imbalance must cause the vibration of axle system, thereby influence the proper functioning and the working life of machine.
The model utility content
During the utility model uses at present coupling owing to run up and axis does not conform to the device damage that causes, a kind of coupling is provided, the cylinder that described coupling is integrated, described cylinder two ends are respectively arranged with the groove that driving shaft and driven axle are installed, and driving shaft and driven axle are fixed by fastening screw and respective slot.Because driving shaft and driven axle are installed in the coupling jointly, and this coupling is incorporate, so the mutual containing in two ends even therefore fastening screw because high speed rotating is loosening, can not come off yet, causes device damage.Simultaneously, because coupling is by two original interconnective individual components, change to integral structure, so after connecting driving shaft and driven axle, its axial location overlaps with its principal inertia axis, can not cause uneven centrifugal inertia force etc., thereby assurance equipment runs well, reduce vibration, increase the service life.
As a kind of improvement of the present utility model, described cylinder is an elastic metallic body cylinder.Because the elastic metallic body not only has the characteristic of metal, but also have small elasticity, have the ability of small adjustment two axial lines relativity shift, also have cushioning effect simultaneously, guarantee that machine runs well, prolonged mechanical working life.
In sum, the beneficial effects of the utility model are conspicuous.Not only have the effect that prevents that part from coming off, and can guarantee mechanical normal operation, prolong service life of equipment so that mechanical axis overlaps with axis of inertia.

Embodiment
Be fit into respectively in the groove 1 at coupling 7 two ends being connected driving shaft 3 on the motor 5 and the driven axle 4 that is connected on the pump 6, and fastening screw 2 is screwed in according to equally spaced mode, thereby coupling 7 and driving shaft 3 and driven axle 4 are tightened together.Open motor, motor drives driving shaft 3 and rotates, and rotates thereby drive the coupling 7 that tightens together with driving shaft 3, because an other end and the driven axle 4 of coupling 7 tighten together, so driven axle 4 rotates along with the rotation of coupling 7, thereby finished the conduction of power.Power through driving shaft 3, coupling 7, driven axle 4, finally reaches pump from motor 5.After pump was subjected to conducting next power, machinery action was finished in entry into service.When transmission shaft because high speed rotating, make that to be used for fastening screw 2 loosening, because coupling 7 two ends itself are connected on driving shaft 3 and the driven axle 4, so the mutual containing in two ends can not fly because of screw, and cause that coupling comes off, and then cause mechanical deterioration.Simultaneously because 7 of coupling are as integral structure, so the axis of driving shaft 3 and driven axle 4 be easy to overlap with axis of inertia, can be because of the even power of centrifugal inertia etc., the generation shafting vibration.Not only guarantee mechanical normal operation, and can prolong the working life of equipment.
Must explanation be the application of the explanation of above-mentioned implementation example and unrestricted creation, only illustrative principle of the present utility model and effect, but not be used to limit protection domain of the present utility model.Rights protection scope of the present utility model should be described in claims.
