Rubber vibration absorber

Abstract

The invention belongs to the technical field of rubber vibration isolation, and particularly relates to a rubber vibration absorber. According to the rubber vibration absorber, the problems that the size of appearance structure of vibration absorber system is large and the pre-tightening amount of each vibration absorber of the vibration absorber system is not easy to control of an existing product are solved. The vibration absorber comprises a rubber vibration absorber pad, a pressing cover and a support shaft, wherein the pressing cover and the supporting shaft are arranged at the two ends of the rubber vibration absorber pad respectively; the supporting shaft is of an inverted T-shape, a mounting boss is arranged at the large end of the supporting shaft, an external thread is arranged at the small end of the supporting shaft, and a through hole penetrating through the axis of the supporting shaft is formed in the middle of the supporting shaft; the rubber vibration absorber pad is cylindrical, the longitudinal section of the rubber vibration absorber pad is in an I-shape, and a supporting shaft mounting hole penetrating through the axis of the supporting shaft is formed in the middle of the supporting shaft; a stepped hole is formed in the pressing cover, the stepped hole comprises a first mounting hole and a second mounting hole which are coaxially arranged, wherein the diameter of the first mounting hole is equal to the aperture of the through hole, the aperture of the second mounting hole is matched with the outer diameter of the small end of the supporting shaft, andan inner thread is arranged in the second mounting hole; and the supporting shaft penetrates through the supporting shaft mounting hole from bottom to top and extends into the second mounting hole and is in threaded connection to the pressing cover and the thread.

Description

technical field [0001] The invention belongs to the technical field of rubber vibration isolation, and in particular relates to a rubber vibration absorber. Background technique [0002] With the continuous development of aerospace technology, the reliability requirements of aerospace products are getting higher and higher, especially the mechanical environment adaptability of products under launch and flight conditions. At present, most of the damping systems suitable for this environment use rubber damping systems. Rubber damping systems can meet the harsh working environments of high temperature, high pressure, high vacuum, ultra-low temperature, and corrosive media in aviation, aerospace, and national defense. In order to make the product meet the mechanical environment such as vibration, overload, transportation, impact, etc., the rubber shock absorber needs to be pre-tightened to a certain extent when installing the rubber shock absorber. At the same time, it meets th...
