A kind of Combined coupler, comprise coupling main body, coupling main body comprise two shaft coupling portions with for being connected the joint of two shaft coupling portions, shaft coupling portion is at one end provided with for connecting the projection of joint, joint includes elastomer block and steel bushing, the two ends of elastomer block are respectively equipped with for settling the mounting groove of shaft coupling portion, the inner side of mounting groove is provided with for settling protruding groove, steel bushing arranges in a tubular form, elastomer block is arranged in steel bushing, the two ends of steel bushing are provided with end cap, between end cap and steel bushing, be the setting that removably connects, end cap comprises top and bottom, bottom is provided with the through hole wearing for shaft coupling portion, elastomer block is made by ebonite.
As concrete technological scheme of the present utility model, main body employing rubber due to coupling, therefore the utility model coupling has the feature of rubber coupling: simple in structure, need not lubricate, mounting or dismounting are convenient, there is the torsional vibration and the impulsive load that relax drive line, prevent that drive line resonance from also can compensate the performance of two axial lines relativity shift, is applicable to moderate torque 50-8000N.The setting of steel bushing and end cap defines the deformation range of elastomer block, prevent the situation that makes axle and elastomer block depart from because elastomer block deformation is excessive, the through hole of end cap bottom, than the large setting of shaft coupling portion external diameter, can make the movement within the specific limits of shaft coupling portion not be subject to the restriction of end cap.
Further, elastomer block is comprised of two identical semicylinders, and steel bushing size and elastomer block are suitable.
The setting that elastomer block is comprised of two identical semicylinders, can be further for the assembling of coupling facilitates.Steel bushing size and the suitable setting of elastomer block, can facilitate elastomer block to put into steel bushing, and in the time of can be for elastomer block deformation, certain space is provided, guaranteed that coupling has torsional vibration and the impulsive load that relaxes drive line, prevented that drive line resonance from also can compensate the performance of two axial lines relativity shift.
Further, the outer ring of steel bushing is provided with outside thread, and end cap is provided with and the suitable internal thread of the outside thread of steel bushing at the externally threaded position of corresponding steel bushing.
Between end cap and steel bushing, adopt and be threaded, there is easy manufacture, connect reliable, easy to use, versatility is good, can repeat the advantages such as dismounting use.
Further, end cap is prism-shaped setting.
End cap is prism-shaped setting, and the shape corner of prism is clearly demarcated, and by the end cap of prism-shaped is set, the locking of using common spanner just can carry out end cap and steel bushing, makes the assembling of coupling and dismounting become more convenient.
Compared with prior art, the utility model has the advantage of: this Combined coupler Placement is simple in structure, easily manufactured, by elastomer block, connect two shaft coupling portions, in coupling using process, can allow institute's coupling shaft have slight axially and move radially, guarantee that coupling is in use steady.
