Abstract

The utility model provides an anti-impact damping self-adaptive vibration isolator, wherein the upper end of a spiral spring is fixed with a connecting sleeve, the connecting sleeve is tightly fixed with a rubber ring through an annular flange, the excircle and the shaft shoulder of the rubber ring are uniformly sleeved with 3 damping friction plates, the assembled spiral spring assembly is directly assembled into a vibration isolator shell to be contacted with a bottom plate, the damping friction plates are contacted with the inner wall of a base to form a damper for inhibiting resonance, when the vibration displacement is smaller, the damping plates are only rubbed with the inner wall of the base by the initial pre-pressure of the rubber ring, and the damping force is smaller; when vibration displacement volume grow, the adapter sleeve drives the rubber circle and vibrates from top to bottom, and rubber circle and upper cover, bottom plate contact cause the rubber circle to warp and lead to rubber circle and damping fin pressure grow, and the damping that finally restraines the resonance also grows thereupon, and rubber circle also plays the spacing effect of buffering in assaulting in addition, consequently the utility model discloses have shock resistance damping self-adaptation function.

Description

Shock-resistant damping self-adaptive vibration isolator

Technical Field

The utility model relates to a vibration isolation buffering technical field specifically is a damping self-adaptation isolator shocks resistance.

Background

At present, the vibration isolators sold in the market have a few damping self-adaption functions, and the functions are obtained through a simple and reliable structure so as to meet different use requirements of customers.

SUMMERY OF THE UTILITY MODEL

The utility model provides a damping self-adaptation isolator shocks resistance, this isolator have damping self-adaptation function, still can keep original vibration isolation performance after experiencing the impact.

The utility model discloses a base, there is the bottom plate base inner chamber lower part through the screw thread soon, and the upper portion of base has the upper cover through the screw thread soon, and base, bottom plate and upper cover constitute the shell of this isolator jointly. The upper end of the spiral spring is fixed with a connecting sleeve, the connecting sleeve is fixedly sleeved with the rubber ring through an annular flange, 3 damping friction plates are uniformly sleeved on the outer circular shaft shoulder of the rubber ring, the assembled spiral spring assembly is directly inserted into the shell of the vibration isolator to be contacted with the bottom plate, the damping friction plates are contacted with the inner wall of the base to form a damper for inhibiting resonance, when the vibration displacement is smaller, the damping friction plates are only subjected to the initial pre-pressure of the rubber ring to rub against the inner wall of the base, and the damping force is smaller; when vibration displacement volume grow, the adapter sleeve drives the rubber circle and vibrates from top to bottom, and rubber circle and upper cover, bottom plate contact cause the rubber circle to warp and lead to rubber circle and damping friction piece pressure grow, finally lead to restraining the damping of resonance also grow thereupon, and rubber circle also plays the spacing effect of buffering in assaulting in addition, consequently the utility model discloses have shock resistance damping self-adaptation function.

Further improvement: the connecting sleeve is improved into a functional component with adjustable working height, and is changed into a working height adjusting system consisting of a hexagonal ring, a cap, an adjusting bolt and an adjusting nut, wherein the adjusting bolt and the adjusting nut are screwed through threads and then are pressed into one end of a spiral spring together, a rubber ring and a damping friction plate are arranged on the cap, then the components are inserted together along the adjusting bolt and are tightly sleeved with an upper step of the adjusting bolt, then the other end of the spiral spring is inserted into a shell of the vibration isolator to be contacted with a bottom plate, and finally the upper cover is screwed.

The utility model has the advantages that:

1. When the vibration is vertical, the spiral spring is used for carrying out main bearing on the equipment and providing the required vibration isolation rigidity; when the vibration is carried out in the horizontal direction, the spiral spring is connected with the rubber ring in series, and the spiral spring and the rubber ring provide rigidity required by vibration isolation; during vibration, the damping friction plate and the inner wall of the base rub to provide damping force for inhibiting resonance, and the magnitude of the damping force changes along with the magnitude of vibration displacement to form self-adaptive damping force; in addition, the rubber ring can also have the limiting and buffering functions in impact.

2. Through the optimization of the working height adjusting system, the working heights of the equipment can be adjusted to be consistent under different bearing capacities according to the actual requirements of the equipment.
