PURPOSE: An asymmetric wire rope isolator and method of manufacture is provided to simplify the design of wire rope isolators and produce a relatively small-scale isolator for use in applications with spatial limitations. CONSTITUTION: A wire rope isolator includes a wire rope(30) manipulated between a pair of mounting blocks(10,20) so that bights of wire rope having elastic properties are formed. A first mounting block(10) has at one end a blind hole(11) and a closely spaced lateral hole(12) that passes completely therethrough the mounting block. On the end of the first mounting block opposite that of the pair of holes is a lone lateral hole(13) that passes completely therethrough the first mounting block. The second mounting block has at opposite ends lateral holes(21,22) that completely pass therethrough the second mounting block. To start the wire rope winding process, one end of the wire rope is maneuvered to the back wall of the blind hole so that the end of the rope abuts the back wall. Tension is applied to the wire rope as it is manipulated through the lateral holes contained in the lateral blocks. The holes of the first block are perpendicular to the holes of the second block. After four U-shaped bights have been formed in generally a cloverleaf pattern about the mounting blocks, the free end of the wire rope is passed completely through the lateral hole nearest the originating blind hole. The wire rope is then secured to the mounting blocks by either crimping or staking. To minimize dimensional and stiffness variation in the assembled isolator, the tension is maintained after the winding process. After the crimping/staking process, the four bights created possesses spring-like properties capable of dampening vibrational energy. The four bights have equivalent dimensions and stiffness. |
