Adjustable composite damping rubber pad

Abstract

The invention discloses an adjustable composite damping rubber pad, and belongs to the field of rubber pads, the adjustable composite damping rubber pad comprises two oppositely arranged rubber pads, a buffer device is arranged between the two rubber pads, the buffer device comprises a flexible rubber sleeve, two groups of friction rings are arranged in the flexible rubber sleeve, the friction rings are of a circular ring structure with an L-shaped section, and the friction rings are arranged in the flexible rubber sleeve. The two friction rings are arranged in a buckled mode, the sides, away from each other, of the two friction rings are fixedly connected with the rubber pad, a fixed magnetic ring is arranged on one side of a circular ring of each friction ring, a cavity is formed in the other side of the circular ring of each friction ring, a sliding magnetic ring is slidably connected into each cavity, and the magnetism of the sliding magnetic rings is the same as that of the fixed magnetic rings. According to the rubber pad, the compression deformation quantity of the rubber pad can be effectively reduced, the service life of the rubber pad is prolonged, and the rubber pad has market prospects and is suitable for popularization.

Description

technical field [0001] The invention relates to the field of rubber pads, and more particularly, to an adjustable composite shock-absorbing rubber pad. Background technique [0002] Rubber pad is a widely applicable metal-rubber structure, which is widely used in places that need to provide vibration damping support. (For example, the application number CN201720501765.2, the utility model patent named "An axial composite rubber pad"; the application number CN202011049540.0, the invention application named "An axial rubber pad and a cross-support bogie"), etc. . Although the above solutions can meet certain vibration damping support requirements, to change the load-bearing capacity and elasticity, for the solutions with application numbers CN201620022210.5 and CN201720501765.2, it can only be achieved by changing the hardness of the rubber. At this time, the creep resistance of the rubber will also change accordingly. Although the proposal of the application number CN202011...

Problems solved by technology

Although the above-mentioned schemes can meet certain requirements for vibration-reducing support, if you want to change its load-bearing capacity and elasticity, for the schemes of application number CN201620022210.5 and application number CN201720501765.2, it can only be achieved by changing the hardness of the rubber. At this time, the creep resistance of the rubber will also change accordingly. Although it is mentioned in the scheme of application number CN202011049540.0 that the stiffness is adjusted by setting through grooves and through holes (paragraph 43 of the specification), when the stiffness adjusted in this way The range is very limited, especially for small-volume rubber pads. To achieve a slightly larger range of stiffness adjustment, it is still necessary to change the hardness of the rubber at the same time, and this method will make the rubber pad molding mold structure complicated. It is inconvenient to process, that is to say, when the use environment changes, the above scheme will seriously affect the vibration damping support effect and service life of the rubber pad, so it can only be used in a single environment. Different environments will have different usage requirements, such as different load requirements, different rigidity requirements, etc., and the existing structure is difficult to meet such usage requirements. Therefore, we propose an adjustable composite shock-absorbing rubber pad to solve the above problems
