The device of transmitting vibrations is formed and is comprised cover, intermediate in rigidity overcoat, the rigidity, intermediate is the elastomeric material with certain rigidity, cover mates mutually in rigidity overcoat, the rigidity, there is certain space each other, intermediate is oppressed in the space between the cover, to be overlapped in rigidity overcoat, the rigidity and fixedlys connected with two rigid objects of the mutual transmitting vibrations of needs respectively in rigidity overcoat and rigidity.
The shape of cross section of cover, intermediate is a closed hoop in said rigidity overcoat, the rigidity, can be circle, polygon or the like, and preferred implementation is a toroidal, and especially the cross section of intermediate is circular, and is stressed even, is convenient to processing and installs.
Cover, rigidity overcoat are metal materials in the said rigidity, and intermediate is the elastomeric material with certain rigidity, comprises rubber or polyurethane or other elastomeric material.
The electromagnetic high frequency vibrating screen transmitting vibrations, the upper end of vibrating arm: put being connected in the rigidity on the vibrating arm, transmission rod is connected rigidity and puts outward; The axle head of vibrating shaft: vibrating shaft is connected in the rigidity puts, sieve box side plate is connected rigidity by fastening watt of seat and puts outward.
Vibration transmission method comprises the steps:
1. the making assembling of cover, intermediate in rigidity overcoat, the rigidity
Cover is made closed hoop in rigidity overcoat, the rigidity, space in the shape of intermediate and rigidity overcoat, the rigidity between the cover is complementary, intermediate is the elastomeric material with certain rigidity, make intermediate reach suitable pre compressed magnitude by precompressed or sulfuration, in the space between the intermediate compressing is overlapped in rigidity overcoat and rigidity;
2. need two rigid objects of mutual transmitting vibrations hinged by the device elasticity of transmitting vibrations
Cover is fixedlyed connected with two rigid objects respectively in the rigidity overcoat, rigidity, and it is hinged that the intermediate with elastomeric material of certain rigidity is finished elasticity;
3. transmitting vibrations
Two rigid objects that need mutual transmitting vibrations, by compressing intermediate transmitting vibrations between the cover in rigidity overcoat and rigidity, the transmitting vibrations mode comprises reciprocating motion, rotatablely moves and and the compound motion between the two and conversion or the like.
The present invention has following advantage and effect: compact conformation, and the stress reasonability improves; The size cross section and the quality of whole vibration transmission system reduce more than 50% than original structure, therefore system's its own inertial is significantly reduced, vibration is transmitted more rapid, efficient, energy-conservation, significantly reducing the effectively impact live load of mitigation system self, the service life of prolongation system of simultaneity factor seismic inertia; In the electromagnetic high frequency vibrating screen transmitting vibrations, make screen box design overall aspect ratio reduce by 10% before owing to use the brand-new vibration transmission system of this compact conformation.Alleviate the overall weight of equipment when saving material, also saved the factory building space that equipment work occupies, also do not needed on-the-spot Installation and Debugging pre compressed magnitude.
