Embodiment 1

[0031] Embodiment one: if figure 1 As shown, a linear anti-vibration, nonlinear anti-strong shock type vibration isolator includes a mounting seat 6, a main shaft 2 that can move up and down and a lower spring seat 8 arranged at the bottom of the seat cavity are arranged in the seat cavity of the mounting seat 6 A main spring 4 for anti-vibration of the main shaft 2 is arranged between the main shaft 2 and the lower spring seat 8, and the main shaft 2 is supported in the seat cavity by the main spring 4.

[0032] The bottom end of the main shaft 2 radially protrudes to form a circle of retaining rings, which are located on the outer wall of the main shaft 2 above the retaining ring, and are arranged in sequence from bottom to top with a lower retaining ring 9, a damping friction ring 11, a damping pressure ring 12, an adjusting nut 14 and The upper buffer pad 15; the inner ring surface of the damping friction ring 11 has a tapered cavity structure with a wide top and a narrow ...

Embodiment 2

[0042] Embodiment two: if figure 2 As shown, a linear anti-vibration, nonlinear anti-strong impact type vibration isolator, the upper end of the lower buffer pad 7 is formed with a step, and a lower buffer cone spring 16 is arranged on the step, and the small ring end of the lower buffer cone spring 16 is connected to the The bottom end of the main shaft 1 is connected and fixed by the lower lock nut 17, and the large ring end of the lower buffer cone spring 16 is connected with the step on the lower buffer pad 7.

[0043] An upper buffer cone spring 18 is arranged on the adjustment nut 14, and the small ring end of the upper buffer cone spring 18 is arranged on the adjustment nut 14 through the upper lock nut 19, and the large ring end of the upper buffer cone spring 18 is against the inner wall of the seat cavity , so that when the main shaft 2 moves horizontally, the upper buffer conical spring 18 provides the reaction force of the nonlinear characteristic in the horizonta...

Abstract

The invention relates to a linear anti-vibration and nonlinear strong-impact-resistant type isolator which comprises a mounting seat, a spindle and a lower spring seat. A retainer ring is radially outwardly and convexly formed at the bottom of the spindle, and a lower closing ring, a damping friction ring, a damping compression ring, an adjusting nut and an upper cushion are sequentially arranged on the outer wall of the spindle from bottom to top and are positioned above the retainer ring; an inner ring surface of the damping friction ring is provided with a big-end-up conical cavity structure, an outer ring surface of the damping compression ring is provided with a big-end-up conical structure, and the upper end surface and the lower end surface of the damping compression ring are respectively higher than the upper end surface and the lower end surface of the damping friction ring; the upper cushion is arranged on the adjusting nut, and the radial size of the upper cushion is larger than the radial size of the adjusting nut. The linear anti-vibration and nonlinear strong-impact-resistant type isolator has the advantages that the tightness of the adjusting nut can be adjusted, so that damping force can be changed; the pitch and the fine diameter of a main spring can be changed, so that series isolators with identical outline dimensions, different rigidity and damping characteristics and different carrying capacities can be acquired.

Description

technical field [0001] The invention relates to a linear anti-vibration, non-linear anti-strong impact vibration isolator. Background technique [0002] With the development of modern military, the requirements for weapons and equipment are further improved, and the environment of electronic equipment is more severe, and the following special requirements are put forward for vibration isolators: [0003] 1. Be able to ensure that electronic equipment can work normally under mechanical environmental conditions such as large acceleration, large displacement, and large impact; [0004] 2. The vibration isolator has the ability of vibration isolation and buffering in three axes. [0005] 3. When the electronic equipment is subject to a large impact acceleration during shipboard strong impact, vehicle impact and airborne crash, it is necessary to ensure the normal operation of the electronic equipment; [0006] However, traditional vibration isolators cannot achieve effective b...
