Semiconductor temperature control stabilization and vibration damping device for high-speed rotating disc inner edge

Abstract

The present invention discloses a semiconductor temperature control stabilization and vibration damping device for a high-speed rotating disc inner edge. The device is mainly composed of a semiconductor temperature control sheet, a temperature sensor, an adjustment washer, a heat dissipating fin barrel, and the like. The device is characterized in that: the temperature of the rotating disc inner edge boundary is controlled by using a thermoelectric cooling effect of the semiconductor thermocouple, so that the thermal stress is generated in the disc inner boundary portion to improve the overallrigidity of the disc, and the critical speed of the disc is increased to realize stabilization and vibration damping functions of the device; and in the device, the disc is mounted on a barrier temperature control structure and is fixed on a transmission shaft by inserting an aluminum joint into a heat insulating sleeve, the temperature of the disc inner edge boundary is controlled by using the semiconductor temperature control sheet, and measurement of the temperature of the disc inner edge boundary is completed by using the temperature sensor. According to the device provided by the presentinvention, the stabilization and vibration damping functions of the discs of different materials and different thicknesses can be completed by controlling the boundary temperature, and the whole device has the advantages of a compact structure, a convenient operation, high reliability and a low cost.
