    摘要： An isolation component for vibratory equipment such as a vibratory trough or feeder includes an isolation spring for supporting the dynamic load of the equipment, and a damper element, preferably an elastomeric ring, arranged against an end of the isolation spring. The damper element prevents excessive motion of the isolation spring due to the vibratory equipment's operating frequency being close to any of the natural frequencies of the bending mode of the isolation spring by applying an opposing load to any such motion. The damper element is preferably an elastomer ring and is arranged along an axis of the support spring. A connector extends from a first end of the isolation spring, adjacent the damper element, toward and past a second end of the isolation spring and is connected to the vibratory equipment. The second end of the isolation spring is supported by a housing supported by external structure such that the weight and dynamic load of the equipment compresses and expands the isolation spring, and excessive expansion of the support spring acts on damper element which is braced against the housing.

    摘要翻译： 用于振动设备（例如振动槽或进料器）的隔离部件包括用于支撑设备的动态负载的隔离弹簧和抵靠隔离弹簧的端部设置的阻尼器元件，优选弹性体环。 由于振动设备的工作频率接近于隔离弹簧的弯曲模式的任何固有频率，所以阻尼元件可以防止隔离弹簧的过度运动，通过对任何这种运动施加相反的载荷。 阻尼元件优选地是弹性体环，并且沿着支撑弹簧的轴线布置。 连接器从隔离弹簧的第一端部邻近阻尼元件延伸并且经过隔离弹簧的第二端并且连接到振动设备。 隔离弹簧的第二端由外部结构支撑的壳体支撑，使得设备的重量和动态负载压缩和膨胀隔离弹簧，并且支撑弹簧的过度膨胀作用在阻尼元件上，阻尼元件支撑在壳体 。

    摘要： An isolation component for vibratory equipment such as a vibratory trough or feeder includes an isolation spring for supporting the dynamic load of the equipment, and a damper element, preferably an elastomeric ring (54), arranged against an end of the isolation spring (56). The damper element prevents excessive motion of the isolation spring due to the vibratory equipment's operating frequency being close to any of the natural frequencies of the bending mode of the isolation spring (56) by applying an opposing load to any such motion. The damper element is preferably an elastomer ring (54) and is arranged along an axis of the support spring (56). A connector extends from a first end of the isolation spring, adjacent the damper element, toward and past a second end of the isolation spring and is connected to the vibratory equipment. The second end of the isolation spring is supported by a housing (50,52) supported by external structure such that the weight and dynamic load of the equipment compresses and expands the isolation spring, and excessive expansion of the support spring (56) acts on damper element which is braced against the housing (50,52).
