More Information
Summary:The utility model discloses an anti-shaft-flying limiting device of a cooling tower fan. The limiting device comprises a limiter, wherein the limiter comprises a base, a support arranged on the base and a limiting ring arranged at the top end of the support, the base is fixed on a cross-shaped beam below the cooling tower fan, and the limiting ring is arranged on the periphery of a transmission shaft of the cooling tower fan in a sleeved and non-contact mode. According to the limiting device, the movement of the transmission shaft is limited within the range of the limiting ring when the high-speed transmission shaft of the cooling tower fan breaks down, the shaft-flying phenomenon is effectively prevented, the destructive power is reduced when the high-speed transmission shaft breaks down, and operation security is improved. Furthermore, the anti-shaft-flying limiting device of the cooling tower fan is simple in structure, convenient to install and low in cost.
