A bottom vibration isolator with independent adjustable vertical and horizontal damping

Abstract

The invention relates to a vertical and horizontal damping separately adjustable bottom part vibration isolator. The vertical and horizontal damping separately adjustable bottom part vibration isolator comprises a base and a bearing barrel which is erected in the inner cavity of the base through a main spring; a circle of outwards-convex baffle ring is formed on the lower end of the bearing barrel; the bearing barrel on the upper end of the baffle ring is sleeved with a damping resonance suppression device; the damping resonance suppression device comprises a lower damping slide sheet, an open ring, a conical ring, an upper damping slide sheet and a damping locking nut which are sequentially socketed outside the bearing barrel; the inner ring surface of the damping barrel is provided with an arc surface structure which is narrow on two ends and wide on a middle part; the conical ring is in butt joint with the arc surface of the damping barrel through the open ring; the surface, which is in butt joint with the open ring, of the conical ring is a slope; and the surface, which is in butt joint with the damping barrel, of the open ring is an arc surface. By adopting the vibration isolator, separate adjustment of damping in each direction can be realized, so that the mechanical environment requirement in each direction is met; and therefore, an optimum vibration isolation and buffering effect in each direction is achieved.

Description

Technical field [0001] The invention relates to a vibration isolator, in particular to a bottom vibration isolator with independent adjustable vertical and horizontal damping, belonging to the technical field of vibration isolator production. Background technique [0002] With the development of modern military and the continuous upgrading of weaponry and equipment, military electronic equipment has become more and more severe due to the external mechanical environment. It is required that the vibration isolator installed in the electronic equipment has good vibration isolation and cushioning effects in all three axes. After the impact, the electronic equipment can work normally. [0003] At present, electronic equipment commonly used is a non-resonant peak anti-strong shock isolator. The patent application (patent) number of this isolator is CN204512269U. The vertical and horizontal damping forces of the isolator are related to each other, that is, the damping force in one directi...

AI Technical Summary

Problems solved by technology

[0005] 1. When the main shaft is rotated, the step where the main spring and the bottom plate cooperate is easy to slip, which makes it impossible to fine-tune the load capacity in the later stage of the vibration isolator assembly

[0006] 2. The outer and inner circles of the upper damping plate and the lower damping plate are not positioned. When the vibration isolator vibrates horizontally, the upper and lower damping plates slide freely

Since the vibration in actual engineering is coupled vibration, that is, vertical and horizontal vibrations exist at the same time, when the upper and lower damping baffles move in circles to stop the curved surface of the inner wall of the shell, it is easy to cause hard damage to the inner wall

[0007] 3. There are edges and corners on the upper and lower edges of the damping friction ring, which are easy to rigidly rub against the curved surface of the inner wall of the mounting seat, which is easy to cause damage
