用于金属轴承的无源无线温度监测套环
摘要：
用于金属轴的无源无线温度监测套环，其特征在于：套环分为同心的外、中、内三层，外层是半环形或者螺旋形金属，内层是圆筒状金属，中间层是包括声表面波温敏谐振器、阻抗匹配电感电容在内的绝缘支撑材料；声表面波温敏谐振器的一端接内层金属筒，另一端通过阻抗匹配电感电容接外层金属中间位置；内层金属的孔径与所要安装的金属轴相吻合，外层金属是无线信号辐射层，其外径和周长根据工作频率而定。这种套环式温度监测器具有适合金属轴承安装、完全无源(无需电池就能工作)、信号覆盖好、简单可靠等优点。
摘要（英）：

A passive wireless temperature monitoring lantern ring for a metal bearing is characterized in that the lantern ring is divided into an outer layer, a middle layer and an inner layer which are concentric, wherein the outer layer is semicircular or spiral metal, the inner layer is cylindrical metal, the middle layer is an insulating supporting material comprising an acoustic surface wave temperature sensitive resonator and an impedance matching inductance capacitor, one end of the acoustic surface wave temperature sensitive resonator is connected with the inner layer metal cylinder, the other end of the acoustic surface wave temperature sensitive resonator is connected with the middle of the outer layer metal through the impedance matching inductance capacitor, the hole diameter of the inner layer metal is matched with that of a metal shaft to be installed, the outer layer metal is a wireless signal radiation layer, and the outer diameter and the perimeter of the outer layer metal are determined according to working frequency. The lantern ring type temperature monitor has the advantages of being applicable to metal bearing installation, totally passive (the lantern ring type temperature monitor can work without a battery), good in signal coverage, simple, reliable and the like.
