Embodiment
The present invention will be further described below in conjunction with drawings and Examples:
A kind of high elastic rubber alloy shaft coupling involved in the present invention comprises input shaft flange plate 1, elastomer 3, output tie-plate 5 and output joint sleeve 7 as shown in Figure 1.The radius R size of elastomer 3 axial two outside end faces is adopted as 40～60mm, can prevent that it is being subjected to producing fatigue failure under the long-term alternate load.The trapezoidal flank of tooth of interior engagement circular arc of input shaft flange plate 1 and the trapezoidal flank of tooth of elastomer 3 outer gearing circular arcs and to be tapering α vertically be 3 °～8 ° being slidingly matched can the compensating axial plaies, eliminate drive gap, vibration and noise reducing, install simultaneously discharge easy.Having the connecting flange that one group of hole 2 is used for input end as shown in Figure 2 on the circumference of input shaft flange plate 1 links.Output tie-plate 5 links with output joint sleeve 7 by one group of screw 6 on the circumference.Have dowel hole 8 at output joint sleeve 7 as shown in Figure 1 and be used to connect output shaft.
The circumferential outer surface of exporting tie-plate 5 as shown in Figure 4 has the left-handed and right-handed thread of β of certain helix angle.Adopt such helix structure, elastomer 3 is more prone to be bonded to an integral body with input shaft flange plate 1 and output tie-plate 5 when sulfidization molding, when elastomer 3 is subjected to the moment of torsion of input shaft flange plate 1 and 5 transmission of output tie-plate, elastomer 3 and input shaft flange plate 1 and output tie-plate 5 can be firm bond together, be not easy to come off.
Input shaft flange plate 1 is by the aluminum alloy material compression molding.It is the circumferential outer surface adhesive coating that adopts at output tie-plate 5 that elastomer 3, embedded steel wire ring 4 become as a whole technology with output tie-plate 5 high strength bond, the material of elastomer 3 is polymer rubber composite materials that weight percentage 2%～8% nanometer ZnOw modification strengthens, by material die pressing precise forming sulfide stress 10～25MPa, 150～180 ℃ of temperature, time 40～80min, the physical and chemical performance and the absorbability of the prepared high elastic rubber alloy shaft coupling elastomeric material that goes out have surpassed U.S. army's standard, long service life.
Embodiment
The polymer rubber composite material that the sulfidation of high elastic rubber alloy shaft coupling elastomer 3, the material of elastomer 3 adopt the nanometer ZnOw modification of weight percentage 3% to strengthen is placed on and carries out the glue refining among open machine X (S) K-230.Be processed with the left-handed and right-handed thread of β of certain helix angle respectively at the circumferential outer surface of output tie-plate 5, after applying special adhesive, to export tie-plate 5 and steel wire ring 4 is placed in the vulcanization die, with extrusion die the raw material that the glue refining obtains is expressed in the vulcanization die again, the vulcanization die that this cover is assembled is placed in the digitizer tablet vulcanizing equipment at last, configure 180 ℃ of sulfurize temperatures, cure time 70 minutes, sulfide stress 46kkg.
