Vibration isolation bearing pedestal utilizing two-stage vibration isolation technology

Abstract

The invention belongs to the field of machinery, and particularly relates to a vibration isolation bearing pedestal utilizing a two-stage vibration isolation technology. The vibration isolation bearing pedestal utilizing the two-stage vibration isolation technology provides multi-directional vibration isolation for a rotating part, is directly installed on a vibration source, conducts direct vibration isolation on the vibration source and does not adopt the mode that vibration isolation of an existing facility is located between a foundation and the whole facility. According to the technical scheme, the vibration isolation bearing pedestal utilizing the two-stage vibration isolation technology comprises a bearing body and further comprises a bearing fixing ring, an inner base fixing ring and a bearing supporting base. The bearing body, the bearing fixing ring and the inner base fixing ring are arranged in a sleeving mode in sequence from inside to outside. The bearing fixing ring and the inner base fixing ring are connected through primary vibration isolation devices. The inner base fixing ring and the bearing supporting base are connected through secondary vibration isolation devices. A primary leaf spring outer ring is arranged on an inner ring of the inner base fixing ring.

Description

Technical field [0001] The patent of the invention belongs to the field of machinery, and specifically relates to a vibration isolation bearing seat using secondary vibration isolation technology. Background technique [0002] Bearings are standard parts widely used in the support of rotating parts in various mechanical products; bearing seats are used to fix, support and position the bearings. [0003] Except for some machines that use vibration to work, vibration is harmful to the machine. Vibration can cause structural loosening, premature fatigue of parts, noise, small-scale earthquakes and other hazards. [0004] Machines with rotating parts will inevitably produce vibrations during work, especially for some harsh working conditions, large resistance and unstable conditions, the resulting vibration is particularly serious. Generally, equipment with severe vibration will have corresponding vibration isolation measures. Vibration isolation equipment is usually added to the part...
