Example Embodiment

[0021] The present invention will be further described in detail below through specific embodiments:

[0022] See also figure 1 with figure 2 ,among them, figure 1 It is a schematic diagram of the structure of the fully enclosed stiffness adjustable vibration isolator of the present invention, figure 2 Yes figure 1 Top view. The fully enclosed stiffness adjustable vibration isolator includes a mounting mandrel 1, a protective rubber cover 2, an upper cover 3, an upper rubber ring 4, a damping rubber ball 5, a shell 6, a lower rubber ring 7, a hollow rivet 8, and a bottom plate 9. The upper cover 3 is arranged on the shell 6 and is threadedly connected with the shell, and the top has a mounting hole for placing the mounting mandrel 1. The bottom edge of the shell 6 is connected with the bottom plate 9 by hollow rivets 8 to form an integral sealed shell. The bottom of the mounting mandrel 1 is deep inside the housing and has a transverse boss structure. The spherical vibration i...

Abstract

The invention relates to a vibration isolation and buffer device for machine-born equipment, in particular to a totally-closed rigidity adjustable type vibration isolator, which comprises a casing, an installation core shaft, a protective rubber cover, an upper rubber ring, a spherical vibration isolation part and a lower rubber ring. The casing is of a sealed structure, the top of the casing is provided with an installation hole where the installation core shaft is arranged, and the spherical vibration isolation part is arranged in the sealed casing and is connected with the bottom of the installation core shaft together. The upper rubber ring is sleeved at the upper portion of a damp rubber ball, and the lower rubber ring is sleeved at the lower portion of the damp rubber ball which is sealed in the casing. The totally-closed rigidity adjustable type vibration isolator adopts a totally-closed structure to have small environment influence, utilizes a combination structure combining the spherical surface and the cylindrical surface to improve vibration isolation and retarding effects, utilizes the structures of the upper rubber ring and the lower rubber ring to limit the swinging of the head of the installation core shaft and improve using safety, and can be suitable for different frequency ranges by rotating the upper cover to adjust the rigidity of the vibration isolator.

Description

technical field [0001] The invention relates to a device for vibration isolation and buffering of airborne equipment, in particular to a fully enclosed vibration isolator with adjustable stiffness. Background technique [0002] Existing vibration isolators are usually open structures, made of rubber and damping rubber materials and skeleton materials (metal, fiber, engineering plastics, etc.), using the attenuation characteristics of molecular friction inside the rubber to slow down and isolate The vibration and shock generated by the vibration source protect the normal operation of the vibration-isolated equipment. Rubber vibration isolators have good damping characteristics and three-way vibration isolation effects. When airborne equipment is not allowed to be used in oily, dusty and other environments, rubber vibration isolators with open structures will not be able to meet the use of such environments Require. [0003] In addition, for ordinary rubber vibration isolato...
