Detailed Description
The large-load elastic support device for a blower gear box according to the present invention will be described in detail with reference to the accompanying drawings and the following detailed description.
As shown in the figures, the utility model discloses a large-load elastic supporting device for fan gear box, including the rubber support body 1 made by rubber materials and five metal baffles 2 that have the centre bore, metal baffles 2 adopt rigid material to make, preferably the steel sheet, the steel sheet is the rectangle structure, the interval between the adjacent metal baffles is equal from top to bottom, each metal baffle 2 is compound in the rubber material of rubber support body, because the centre bore is provided with to the center of steel sheet, therefore the rubber material of rubber support body fills in the centre bore naturally, from this, firmly compound the steel sheet and form an entirety in the rubber material, rubber support body 1's rubber material makes each metal baffle be provided with the annular 3 that the cross-sectional shape is isosceles trapezoid structure after carrying out compound cladding through the adhesive with each metal baffle, the rubber material of rubber support body is in the thickness of steel sheet edge cladding to adjacent two steel sheets between increase gradually, finally, an isosceles trapezoid cross-sectional structure is formed, so that stress is dispersed and uniformly distributed, and stress concentration at the edge is reduced.
Furthermore, the edge of each metal partition plate 2 is coated with an encapsulating layer, so that all the steel plate surfaces are coated, the central hole is positioned in the center of the steel plate, the area of the central hole is 30-60% of the area of the partition plate, taking the embodiment as an example, the side length of the steel plate is 240mm x 240mm, the diameter of the central hole is 90mm, in addition, inclined surface bulges 4 connected with the rubber support body are arranged on the upper surface and the lower surface of the four corner positions of the metal partition plate 2, the inclined surface bulges 4 are in curved surface transition with the connection part of the rubber support body, the supporting capacity is further improved, the stress concentration of the edge is reduced, in addition, in order to facilitate installation, one metal partition plate at the bottommost layer is used as a bottom plate, and.
