Abstract
Rubber pad is including vulcanizing roof, the rubber body and the bottom plate of connecting, its characterized in that roof and at least one central point of bottom plate put to open and have the central through hole, rubber body central point put to open and have the axial hole, the diameter of axial hole be less than the diameter of central through hole, and axial hole and roof and bottom plate between all have a rubber body. The utility model provides a rubber pad, through the improvement to the rubber pad structure, stress concentration when preventing rubber body pressurized avoids the rubber body to wear and tear mutually with the metal sheet, and rubber pad life is longer.
Description
Technical field
This utility model relates to rubber elastic element field, particularly to the rubber blanket of a kind of metallic plate with rubber bodies sulfuration.
Background technology
Rubber blanket and rubber metal pad are the damping elements of conventional rubber-metal compound, can be widely applied to various vibration damping place, very general particularly in applying in the bogie of rolling stock. For round rubber pad, in order to reduce its axial rigidity, can in center axial aperture, round rubber pad is become ring-shaped rubber pad, it is illustrated in figure 1 endoporus inner concave shape ring-shaped rubber pad, is characterized in that the endoporus rubber profile of rubber bodies 2 is that the bonding transition position of indent and top board 1 and base plate 3 has fillet. As in figure 2 it is shown, deformation during ring-shaped rubber heap stress, rubber profile indent can avoid the rubber of abutting edge P will not wear away mutually with metallic plate.
Ring-shaped rubber pad is in going out mold process, because the endoporus of rubber bodies 2 is indent, the die insert at endoporus place must be divided into many lobes and could release from the inside, so endoporus necessary sufficiently large 4. When the diameter of endoporus is less, the endoporus of rubber blanket is extracted out typically via die core axle entirety and is formed, and rubber gasket structure is as it is shown on figure 3, be characterized in that endoporus does not have an indent, but straight type. During stress as shown in Figure 4, rubber bodies 2 can form tensile stress concentration at endoporus bonding part P. The main fatigue rupture of rubber bodies is that tensile stress concentrates position to produce be full of cracks, peels off with metallic plate in bonding part, and rubber bodies and metallic plate wear away mutually, the final service life shortening product. For preventing stress from concentrating, it is to avoid rubber bodies and metallic plate wear away mutually, necessary rubber gasket structure is improved.
Utility model content
The rubber blanket that this utility model provides, by the improvement to rubber gasket structure, it is prevented that during rubber bodies pressurized, stress is concentrated, it is to avoid rubber bodies and metallic plate wear away mutually, rubber blanket longer service life.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: rubber blanket, including top board, rubber bodies and base plate that sulfuration connects, it is characterized in that described top board and at least one center of base plate have central through hole, described rubber bodies center has axial hole, the diameter in described axial hole is less than the diameter of central through hole, and is respectively provided with rubber bodies between described axial hole and top board and base plate.
Preferably, described top board is equal with the thickness of base plate, and the radial difference in described central through hole and axial hole is not less than the one-tenth-value thickness 1/10 of top board.
Preferably, the center of described top board and the center of base plate all have central through hole, and described axial hole is through hole.
Preferably, the center of described base plate has central through hole, and described axial hole is the axial blind hole opened from rubber blanket bottom up, has rubber bodies between diapire and the bottom surface of top board in axial hole.
Preferably, the described angle between axial hole diapire and sidewall is fillet.
Preferably, the diameter in described axial hole is less than 90mm.
At least one center of rubber blanket of the present utility model, top board and base plate has central through hole, and rubber bodies center has axial hole, and the diameter in axial hole is less than the diameter of central through hole, and is respectively provided with rubber bodies between described axial hole and top board and base plate. There is between central through hole and axial hole one layer of rubber bodies, the edge of central through hole is encased by rubber bodies, and the end face of the bottom surface of top board and base plate is covered by rubber bodies entirely, when rubber blanket compressive deformation, prevent from rubber bodies from forming tensile stress to concentrate, rubber bodies and metallic plate is avoided to wear away mutually, rubber blanket longer service life.

Detailed description of the invention
Following by drawings and Examples, this utility model is further described.
Embodiment one:
As shown in Figure 5, rubber blanket, including top board 1, rubber bodies 2 and base plate 3 that sulfuration connects, the center of described top board 1 and the center of base plate 3 all have central through hole 4, described rubber bodies 2 center has axial hole 5, described axial hole 5 is through hole, and the diameter in described axial hole 5, less than the diameter of central through hole 4, is respectively provided with rubber bodies 2 between described axial hole 5 and top board 1 and base plate 3. Described top board 1 is equal with the thickness of base plate 3, and described central through hole 4 and the radial difference B in axial hole 5 are not less than the one-tenth-value thickness 1/10 of top board 1.
Embodiment two:
As shown in Figure 6, rubber blanket, including top board 1, rubber bodies 2 and base plate 3 that sulfuration connects, the center of described base plate 3 has central through hole 4, described rubber bodies 2 center has axial hole 5, described axial hole 5 is the axial blind hole opened from rubber blanket bottom up, and the diameter in described axial hole 5, less than the diameter of central through hole 4, has rubber bodies 2 between described axial hole 5 and base plate 3. Between diapire and the bottom surface of top board 1 in axial hole 5, there is rubber bodies 2. Described top board 1 is equal with the thickness of base plate 3, and described central through hole 4 and the radial difference in axial hole 5 are not less than the one-tenth-value thickness 1/10 of top board 1. The described angle between axial hole 5 diapire and sidewall is fillet.
