SPRING VIBRATION INSULATOR Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: spring vibration insulator has a cylindrical spring, bushings with a screw load whose pitch corresponds to the pitch of the cylindrical spring. The bushings are built into the cylindrical spring and has threaded openings. Cylindrical permanent magnets with a thread on the external surface are received in the openings. The magnets are magnetized in the axis direction and their opposite poles face each other. The bellows is freely mounted coaxially inside the cylindrical spring, one end face of the bellows being connected to the support and the other one being in a contact with the end face of the cylindrical permanent magnet. One end of the cylindrical spring is rigidly connected to the support and the other one can be rigidly connected to the object. EFFECT: improved design. 1 dwg
