The invention discloses a novel rubber flexible hinge filled with metal rubber. The novel rubber flexible hinge comprises a rubber body and a metal rubber filler, wherein the rubber body is made of rubber material in an integral manner, and the rubber body is composed of cylindrical connectors on the upper end and the lower end and a double-circular-arc structure which is located between two connectors; a cavity body is formed in the middle part of the upper end cylindrical connector and the double-circular-arc structure, the cavity is vertical to the cylindrical connectors on the upper end and the lower end, the height of the cavity body penetrates through the double-circular-arc structure from the upper bottom surface, and the distance from the length of the cavity body to the bottom of the double-circular-arc structure or the edge of the top is 5-15cm; and the width of the cavity body is 70-80% of the width of the middle part of the double-circular-arc body, the cavity body is filled with the metal rubber filler, and the metal rubber filler is a grid-shaped structural body which is formed by winding superposing and extruding a plurality of metal wires which are coiled to be helical. According to the novel rubber flexible hinge, the high elasticity in the rotation direction is kept, and meanwhile, the rigidity in the compression direction is enhanced.
Description
technical field [0001] The invention relates to a flexible hinge, in particular to a novel rubber flexible hinge filled with metal rubber. Background technique [0002] At present, flexible hinges have become a new type of hinge widely used in precision machinery. The most widely used materials are spring steel 65Mn, and sometimes titanium, beryllium copper and other metal materials. However, with the continuous development of science and technology, the range of motion of traditional flexible hinges can no longer meet the requirements, and large deformation flexible hinges have become one of the hotspots of current research. Large-deformation flexible hinges can be made of rubber materials with greater elasticity, but their rigidity cannot be guaranteed. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a new rubber flexible hinge filled with metal rubber that not only maintains high ...
