Abstract

The patent of the present invention belongs to the field of machinery, and specifically relates to a vibration-isolation bearing seat utilizing secondary vibration-isolation technology. It provides multi-directional vibration isolation for rotating parts, and is directly installed at the vibration source to directly isolate the vibration source. It is not between the foundation and the whole equipment like the vibration isolation of existing equipment. The technical solution of the present invention includes a bearing main body, a bearing fixing ring, an inner seat fixing ring and a bearing support seat. The bearing main body, the bearing fixing ring and the inner seat fixing ring are sleeved in sequence from the inside to the outside. The bearing The fixed ring and the inner seat fixed ring are connected by a primary vibration isolation device; the inner seat fixed ring and the bearing support seat are connected by a secondary vibration isolation device, and the inner ring of the inner seat fixed ring is provided with a primary Leaf spring outer 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 utilizing secondary vibration isolation technology. Background technique [0002] Bearings are standard parts widely used in the support of rotary parts in various mechanical products; bearing housings are components used to fix, support and position bearings. [0003] Except for some machines that use vibration to work, vibration is harmful to machines. Vibration can cause structural looseness, premature fatigue of parts, and noise, small-scale earthquakes and other hazards. [0004] Machinery with rotating parts will inevitably generate vibration during operation, especially for some working conditions with harsh working environments, large resistance and instability, the vibration generated is particularly serious. Generally, equipment with severe vibration will have corresponding vibration isolation measures. Vibration is...
