Description
Technical Field
The utility model relates to a coupler equipment technical field especially relates to an improve shaft coupling.
Background
The shaft coupling mainly is used for being connected between axle and the axle to transmission motion and torque, among the prior art, most shaft couplings adopt the bolt to fix, need constantly adjust the elasticity degree of every bolt when using, the time-wasting, work efficiency is low, and at the shaft coupling during operation, inside does not have the shock attenuation part, produces the destruction to the collision of shaft coupling easily, has reduced the life of connecting axle.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem provide a adapt to and improve shaft coupling, solved waste time through the screw-thread fastening and at the inside shock pad that sets up of connecting axle body, work efficiency is low, and at the shaft coupling during operation, inside does not have the shock attenuation part, produces the destruction to the shaft coupling collision easily, has reduced the life's of connecting axle problem.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an improve shaft coupling, includes shaft coupling body and main shaft, connecting axle body surface left end has the spinal canal helicitic texture and has the elasticity fluting, still includes external nut, the external nut internal surface has straight tube helicitic texture, shaft coupling body surface has the spinal canal helicitic texture and has the straight tube helicitic texture with external nut internal surface and cooperatees, shaft coupling body surface has the spinal canal helicitic texture and has one side that the elasticity fluting from the right side diameter of left side and reduce gradually, the cavity is left to shaft coupling body inboard, the scarf joint of cavity left side inner end has the shock pad.
Further, the method comprises the following steps: the external nut is provided with a fastening and detaching groove on the outer surface.
Further, the method comprises the following steps: the coupler is made of aluminum alloy.
The utility model has the advantages that: the time waste is solved through the threaded fastening and the shock pad that sets up inside the connecting axle body, and work efficiency is low, and at the shaft coupling during operation, inside does not have the shock attenuation part, produces the destruction to the shaft coupling collision easily, has reduced the life's of connecting axle problem.

Labeled as: the coupler comprises a coupler body 1, a main shaft 2, an external nut 3, a dismounting groove 31, a cavity 4, a damping pad 5 and an elastic groove 6.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 and 2, an improve shaft coupling, including shaft coupling body 1 and main shaft 2, 1 surperficial left end of connecting axle body has canalis spinalis helicitic texture and has elasticity fluting 6, still includes external nut 3, 3 internal surfaces of external nut have straight tube helicitic texture, 1 surface of shaft coupling body has canalis spinalis helicitic texture and has straight tube helicitic texture with 3 internal surfaces of external nut and cooperate, 1 surface of shaft coupling body has canalis spinalis helicitic texture and has one side that elasticity fluting 6 reduces from the right side to the left side diameter gradually, cavity 4 is left to 1 inboard of shaft coupling body, cavity 4 left side inner end has inlayed the shock pad 5.
Through the screw-thread fastening with at the inside shock pad that sets up of connecting axle body, the waste time has been solved, work efficiency is low, and at the shaft coupling during operation, inside does not have shock attenuation part shock pad 5, produce destruction to the shaft coupling collision easily, the problem of the life of connecting axle has been reduced, elastic grooving 6 has on the shaft coupling, during the installation, loosen external nut 3, make shaft coupling body 1 be in with main shaft 2 connection position and relax the state, can easily overlap on main shaft 2, accurate back in shaft coupling location, it has the taper pipe helicitic texture and has straight tube helicitic texture to cooperate with external nut 3 internal surfaces through shaft coupling body 1 surface, cramp the shaft coupling, thereby the transmission moment of torsion, light convenient effect has been reached.
On the basis, as shown in fig. 3, the external nut 3 has a fastening and detaching groove 31 on the outer surface, and when detaching, the fastening and detaching groove 31 is clamped by a tool, and the elastic slot 6 recovers elasticity after being reversely loosened.
On this basis, the shaft coupling adopts the aluminum alloy material, and the aluminum alloy material of adoption has density little, intensity is high, the processing property is good and welding property is good some, has improved the life of shaft coupling.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
