Coupling
Technical field
The utility model relates to coupling.
Background technique
Coupling is the bindiny mechanism that is used for connecting motor and gear-box; Make it the mechanical parts of common rotation with transmitting torque, motor joint and gear-box joint all adopt spring steel plate to process on the coupling, because spring steel plate has certain rigidity and fragility; It is just therefrom separated automatically when moment of torsion surpasses certain value; Coupling damages, and Safety performance is not high, and descend to working life.
The model utility content
The technical problem that the utility model will solve is that existing coupling Security is not high, thereby coupling is provided.
In order to solve the problems of the technologies described above; The utility model is realized through following technological scheme: coupling; Comprise the coupling body; Said coupling body is provided with first steel disc of motor joint and second steel disc of gear-box joint, is provided with damping device between said first steel disc and second steel disc, and said damping device is fixedly connected with first steel disc, second steel disc respectively.
Preferably; Said damping device is a rubber; Be respectively equipped with the groove that matches with first steel disc, second steel disc on the said rubber; Also can be other damping devices, rubbery intensity height, good combination property, intensity ability high, that restore rapidly, and have good physical and mechanical property and chemical stability.
Preferably, also be provided with oil groove on the said coupling body, the setting of oil groove prevents that to a certain extent the grease of gear-box from draining to motor the inside, and is simple in structure, easy to use.
Preferably, the cross section of said oil groove is a rectangular, also can be the oil groove of other structures, and elongate slots is simple in structure, and is easy to process, and using effect is good.
In sum, the advantage of the utility model: through damping device first steel disc is linked to each other with second steel disc, when transmission was impacted, damping device started protection and buffering effect, and in the working life of having improved coupling, attachment security is reliable, has improved practicability.

Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, coupling comprises the coupling body; Said coupling body is provided with first steel disc 1 of motor joint and second steel disc 2 of gear-box joint, is provided with damping device 3 between said first steel disc 1 and second steel disc 2, and said damping device 3 is fixedly connected with first steel disc 1, second steel disc 2 respectively; Said damping device 3 is a rubber, is respectively equipped with the groove that matches with first steel disc 1, second steel disc 2 on the said rubber, also can be other damping devices 3; Rubbery intensity height, good combination property, intensity ability high, that restore rapidly, and have good physical and mechanical property and chemical stability, also be provided with oil groove 4 on the said coupling body; The setting of oil groove 4 prevents that to a certain extent the grease of gear-box from draining to motor the inside, and is simple in structure; Easy to use, the cross section of said oil groove 4 is a rectangular, also can be the oil groove 4 of other structures; Elongate slots is simple in structure, and is easy to process, and using effect is good.
With first steel disc 1, second steel disc 2 respectively be arranged on the rubber upper groove and be fixedly connected; The motor joint that makes the coupling after the installation is linked to each other with motor; The gear-box joint of coupling links to each other with gear-box; When motor when high speed transmission or moment of torsion surpass certain value, rubber starts cushioning and protection.
Through damping device first steel disc is linked to each other with second steel disc 2, when transmission was impacted, damping device started protection and buffering effect, and in the working life of having improved coupling, attachment security is reliable, has improved practicability.
