Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 , as shown in 2, a suspension-type non-resonant vibration isolator, including a suspension core 1, a lower spring seat 2, a wire mesh 3, a main spring 4, a bottom spring 5, an upper spring seat 6, and a drum-shaped leaf spring damper 7 , Opening tapered collar 8, upper tapered collar 9, base 10, shell 11.

[0016] The lower end of the suspension core 1 has an internally threaded hole. The suspension device is connected with the lower spring seat 2 by sliding fit, and is threaded with the upper spring seat 6. The main spring 4 and the bottom spring 5 are embedded in the upper and lower spring seats 6 and 2. The bottom spring 5 is set on the suspension core 1, the main spring 4 is sleeved outside the bottom spring 5, the upper spring seat 6 is dry frictionally connected with the waist drum-shaped spring plate damper 7, the upper e...

Abstract

The invention relates to a suspension type resonance-free vibration isolator. The lower end of a suspension core is connected with a lower spring seat in a sliding fit mode and the upper end of the suspension core is connected with an upper spring seat through threads. The upper spring seat and a waist-drum-shaped leaf spring damper are connected in a dry friction mode. A main spring and a bottom spring are embedded between the upper spring seat and the lower spring seat. The upper end of the waist-drum-shaped leaf spring damper is connected with a base through a conic opening retainer ring and an upper conic retainer ring. The base is connected with a shell through threads. The shell and the upper end of the lower spring seat are filled with wire meshes. The pre-compression amount of the main spring is adjusted through adjusting the threads on the suspension core, the resonance peak value is eliminated through dry-friction damping force between the upper spring seat and the damper, the upper end of the damper is clamped through the conic retainer ring, the upper end of the conic retainer ring is connected with a bottom cover, the bottom cover is connected with the shell through threads, and the damping force of the damper can be adjusted through adjusting the threads between the bottom cover and the shell. The suspension type resonance-free vibration isolator has the advantages of being adjustable in damping and spring pre-compression amount, free of resonance, resistant to impact, capable of achieving the good vibration isolation effect and the like.

Description

technical field [0001] The invention relates to a vibration isolation device, in particular to a suspension type non-resonance vibration isolation device. Background technique [0002] Among the currently disclosed vibration isolators, except for bottom-supported non-resonant vibration isolators and back-to-back type non-resonant vibration isolators, no resonance-free vibration isolators have yet appeared in suspension type vibration isolators. With the rapid development of modern industry, higher and higher requirements are put forward for the anti-interference ability of some precision equipment in vibration, shock, acceleration and other environments. The existing suspension type vibration isolator cannot solve the problem of resonance Effects on precision equipment. Therefore, for some precision equipment that needs to be suspended, a new suspension shock absorber is required. Contents of the invention [0003] The technical problem to be solved by the present invent...
