[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] like figure 1 As shown, the present invention includes a turbine rotor 9, an electrostable current displacement sensor, and two bearing housing 13 (the number of bearing hoses is not limited to two). The turbine rotor 9 is provided with two bearing support sections 91 (the number of bearing support segments 91 is the same as the number of bearing housing 13). The bearing housing 13 is provided with a support housing 21, such as Figure 2-4 As shown, the support housing 21 is provided with a radial torch bearing 22, and a plurality of shaped memory alloy (SMA) spring 23 and a ring shape are provided between the outer wall of the bearing housing and the support housing 21. The wire mesh block 24, the multi-group shaped memory alloy spring 23 is uniformly arranged in the circumferential direction, each set of shape memory alloy spring 23 includes two shape memory alloy sp...
