The low-frequency large-damping spring composite vibration isolator is characterized in that an upper steel plate (2), a positioning device (3), a spring (4), a pull rod (5), a hexagon bolt (6) and a lower steel plate (7); an upper rubber anti-skidding gasket (1) is arranged on the upper steel plate (2), the positioning device (3) is fixedly installed below the upper steel plate (2), the spring (4) is fixedly installed below the positioning device (3), the lower steel plate (7) is arranged below the spring (4), the hexagon bolt (6) is arranged on the lower steel plate (7), and the pull rod (5) is fixedly arranged on the hexagon bolt (6); and a lower rubber anti-skidding gasket (8) is arranged below the lower steel plate (7).

Description

technical field [0001] The invention discloses a vibration isolator, in particular to a low-frequency large damping spring composite vibration isolator. Background technique [0002] The vibration isolator is an elastic element connecting the equipment and the foundation to reduce and eliminate the vibration force transmitted from the equipment to the foundation and the vibration transmitted from the foundation to the equipment. Spring isolators are the most commonly used type of steel isolators. There are spiral, disc, ring and plate forms. Existing vibration isolators have small static compression, high natural frequency, poor vibration isolation performance, easy to be eroded by oil, water, etc., large changes in working temperature are easy to affect performance, easy to age, creep and many other problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device with large static compression, low natural fr...
