Description
Technical Field
The invention belongs to the field of vibration isolation devices, and particularly relates to a rubber vibration isolation device.
Background
The silicon rubber material has viscoelasticity and a high loss factor, and can reduce energy transmission through internal consumption in the deformation process of the silicon rubber material, so that the silicon rubber material is widely applied to vibration isolation design in the fields of electronics, electrical appliances and the like as a damping material.
The silicon rubber vibration isolation structure has lower rigidity and larger deformation, so a metal framework is usually added into the silicon rubber vibration isolation structure to play a role in protection and support. The traditional bowl-shaped and diamond-shaped rubber vibration isolation structures widely applied at present mostly relate to the problem of bonding between rubber and metal, and due to the limited bonding strength, the situation that the rubber and the metal are debonded due to impact or fatigue overload often occurs in the use process, so that the vibration isolator is damaged. The T-shaped vibration isolator is special in structure, the problem of bonding between rubber and a metal interface can be solved through the limiting bushing and the gasket, but the traditional T-shaped vibration isolator is limited by the structure and is connected with a vibration isolation device through a flange hole with certain size requirement. The mounting mode has high requirement on the size of a mounting flange hole, occupies the structural design space of a vibration isolation device and has great limitation.
Along with the continuous upgrading and the development towards lightweight of electronic equipment, the limitation of the installation mode of the T-shaped vibration isolator to the application range of the T-shaped vibration isolator is more and more obvious. Therefore, a novel vibration isolation structure which has a simple mounting structure and can effectively avoid the phenomenon of debonding rubber and metal in the use process needs to be designed urgently.
Disclosure of Invention
The invention aims to: the rubber vibration isolator structure overcomes the defects in the prior art, and is a novel rubber vibration isolator structure which can prevent the debonding of rubber and metal in the rubber vibration isolator and is simple in mounting structure.
The technical scheme of the invention is as follows: a rubber vibration isolation device is characterized in that: the rubber part is provided with a through hole in the middle, and the limiting bush and the bolt penetrate through the middle of the rubber part; the rubber pieces are arranged up and down, the mounting frame is clamped in the middle, the mounting frame is fixed on the mounting bottom plate through a fastening bolt, the limiting gasket is riveted with the limiting bushing, and the limiting bushing is sleeved on the bolt; the mounting frame, the rubber part, the limiting spacer and the limiting bush jointly form a vibration isolator, and the vibration isolator is fixed on the mounting upper plate through bolts.
The mounting frame is fixed on the mounting bottom plate through at least two fastening bolts.
The bottom of the mounting frame is provided with a protruding circular ring which limits the position of the mounting frame.
A circular groove is processed on the mounting bottom plate, the rubber pieces are of a T-shaped structure, the ratio of the radius r of the groove to the maximum outer diameter d formed by the two rubber pieces is r: d which is 0.55-1: 1, and the ratio of the depth X of the groove to the thickness K of the rubber pieces is X: K which is 1.1-2: 1.
The ratio of the total height L of the mounting frame to the height H of the vibration isolation device is 0.15-0.8: 1.
The mounting frame is provided with a flange hole structure, and the ratio of the thickness h to the maximum outer diameter d of the rubber piece is h: d which is 0.1-1: 1.
The invention has the following remarkable effects:
(1) The rubber part is fixed in the form of the limiting spacer and the limiting bush, so that damage caused by displacement overload in the use process of the vibration isolator is avoided, meanwhile, rubber and metal in the limiting structure do not need to be bonded, and the problem that the bonding interface of the rubber and the metal of the vibration isolator is debonded in use is avoided.
(2) The mounting frame structure is introduced in the mounting mode, and the defect that a mounting lug is required to be arranged when the traditional T-shaped shock absorber is mounted is overcome. Under the same condition, the novel vibration isolation structure with the mounting frame structure can adapt to a smaller structural space compared with the traditional novel vibration absorber, and meanwhile, the novel vibration isolation structure has a simpler mounting structure.
(3) The invention has novel structure, eliminates the problem of debonding of a rubber and metal bonding interface, has simple installation structure and does not need to consider installation lugs. The vibration isolator is successfully applied to certain electronic equipment at present, and has the advantages of good vibration isolation effect, stable structure and high safety.
