Three-direction spacing type wire-rope vibration isolator

Abstract

The invention relates to a three-direction spacing type wire-rope vibration isolator which is used for the vibration isolation of various electromechanical apparatuses and facilities in the fields of ships, vehicles, aviation, buildings and the like. A three-direction elastic spacing mechanism is arranged between upper and lower bearing splints of the wire-rope vibration isolator and is composed of a rigid rod and a spacing seat ring, wherein different spacing clearances are designed between the rigid rod and a rubber layer compounded in an inner cavity of the spacing seat ring according to spacing requirements. When the wire-rope vibration isolator bears vibration or impact in any direction, once a dynamic displacement exceeds the designed spacing clearance valve, the rigid rod is in contact with the rubber layer compounded in the inner cavity of the spacing seat ring, so that the upper and lower bearing splints of the wire-rope vibration isolator are prevented from being further and mutually dislocated in the direction, thereby achieving the purpose of elastic spacing. Thus, the excellent softened nonlinear rigidity and damping characteristic of the wire-rope vibration isolator are kept, and the restriction requirements for displacements in three directions in engineering can be met. The wire-rope vibration isolator provided by the invention has a compact structure and reliable performance.

Description

technical field [0001] The invention relates to a three-way limit type steel wire rope vibration isolator, which is used for vibration isolation of various electromechanical equipment and facilities in the fields of ships, vehicles, aviation, construction and the like. Background technique [0002] At present, various types of vibration isolators (shock absorbers) such as rubber type shock absorbers, wire rope vibration isolators, air springs, etc. Vibration isolation, cushioning (resistance) and transmission of structural noise are reduced to achieve the purpose of protecting the safety and normal operation of equipment and facilities. In particular, wire rope isolators with multi-directional softening nonlinear stiffness and damping characteristics have been widely used. [0003] The biggest structural feature of the current wire rope vibration isolator is that it has a multi-directional large displacement elastic deformation function, and the maximum dynamic deformation ...
