Generally, there will be a strong mechanical transmission movement in the use position of the bearing, and strong vibration will occur at the bearing. À temperature-measuring sensor of the bearing is generally mounted in a bearing sleeve. When the bearing rotates at a high speed, relative vibration will occur between the temperature-measuring sensor and the bearing sleeve. If the vibration is violent, a temperature-measuring thermal resistor will be damaged. The current temperature-measuring thermal resistor is prone to damage during use due to its poor anti- vibration performance.
Therefore, it is necessary to research and develop a temperature-measuring thermal resistor with good anti-vibration performance in order to solve at least one of the above technical problems.

Embodiment I: As shown in Figs. 1 and 2, the present invention provides a temperature-measuring thermal resistor with good anti-vibration performance, comprising: a thermal resistor 1, a main body 2, a conducting wire 3, and a protective casing 4. The thermal resistor 1 is located in a closed end of the protective casing 4, and the other end of the protective casing 4 is connected to one end of the main body 2. The main body 2 is internally provided with a sliding hole 5 having openings at two ends thereof. The opening arranged at the end of the main body 2 close to the protective casing 4 is a first circular hole. The diameter of the first circular hole is smaller than that of the sliding hole 5. The opening arranged at the other end of the main body 2 is a second circular hole, and the diameter of the second circular hole is the same as that of the sliding hole 5. A hollow spring fixing member 9 is provided in the second circular hole. A hollow slider 6 is slidably provided in the sliding hole 5. A first compression spring 7 is provided between the slider 6 and an inner wall of the main body 2 at the end thereof close to the protective casing 4. A second compression spring 8 is provided between the slider 6 and the spring fixing member 9. The thermal resistor 1 is connected to one end of the conducting wire 3. The other end of the conducting wire 3 passes through the first circular hole, the first compression spring 7, the slider 6, the second compression spring 8 and the spring fixing member 9 in sequence, and is fixedly connected to the slider 6 by means of a wire fixing member 13.
It can be understood that in the case where the temperature-measuring thermal resistor is mounted on a mechanical device, when the thermal resistor is subjected to mechanical vibration, since the first compression spring 7 and the second compression spring 8 are in a compressed state in the main body 2, the slider 6 will quickly return to an original position under the action forces of the first compression spring 7 and the second compression spring 8, thereby reducing the vibration the thermal resistor 1 is subjected to, and prolonging the service life of the thermal resistor 1.
Embodiment II:
As shown in Figs. 2 and 4, this embodiment differs from the above embodiment in that theU501993 spring fixing member 9 comprises a hollow cylindrical plug 91; one end of the cylindrical plug 91 is located in the second circular hole; the other end of the cylindrical plug 91 is provided with a fixing portion 92 having a flange; the fixing portion 92 is provided with a through hole; a side wall of the main body 2 is provided with a threaded hole in a position corresponding to the through hole; and a fixing screw 12 passes through the through hole and extends into the threaded hole.
It can be understood that the cylindrical plug 91 is located in the second circular hole, ensuring that the second compression spring 8 is in a compressed state, and the fixing portion 92 is fixedly connected to the side wall of the main body 2 by means of the fixing screw 12, facilitating subsequent mounting and dismounting.
Preferably, in one of the preferred technical solutions of this embodiment, at least two pairs of through holes and threaded holes are provided in the fixing portion 92 and the side wall of the main body 2. The at least two pairs of through holes and threaded holes can increase the stability of connection between the fixing portion 92 and the side wall of the main body 2.
Preferably, in one of the preferred technical solutions of this embodiment, four pairs of through holes and threaded holes are provided, and the fixing portion 92 is connected to the side wall of the main body 2 via the four pairs of through holes and threaded holes, so that not only the connection is firm, but also the mounting and dismounting are facilitated.
Preferably, in one of the preferred technical solutions of this embodiment, the four pairs of through holes and threaded holes are uniformly distributed circumferentially. The four pairs of through holes and threaded holes uniformly distributed circumferentially allow the fixing portion 92 and the side wall of the main body 2 to be uniformly stressed during connection, so that edge warping is less prone to occur, and the appearance is attractive.
Preferably, in one of the preferred technical solutions of this embodiment, a first rubber cushion ring is provided on a side wall of an inner hole of the cylindrical plug 91. The first rubber cushion ring 10 can prevent the conducting wire 3 from rubbing against the side wall of the inner hole of the cylindrical plug 91 when being subjected to vibration, resulting in damage to the conductive wire 3.
Embodiment lil: As shown in Figs. 1, 2 and 3, this embodiment differs from the above embodiments in that the end of the protective casing 4 close to the main body 2 is provided with a resilient corrugated structure portion 41. It can be understood that when the protective casing 4 is subjected to vibration, the corrugated structure portion 41 is stretched or compressed, so that not only can the vibration be reduced to protect the thermal resistor 1, but also the service life of the protective casing 4 can be prolonged.
Preferably, in one of the preferred technical solutions of this embodiment, a second rubbdsJ501993 cushion ring 11 is provided in the first circular hole. The second rubber cushion ring 11 prevents the conducting wire 3 from rubbing against the inner wall of the first circular hole.
Preferably, in one of the preferred technical solutions of this embodiment, an outer side wall of the main body 2 is further provided with a helical fixing member 14. The helical fixing member 14 facilitates connection with a mechanical device.
Preferably, in one preferred technical solutions of this embodiment, the wire fixing member 13 is an adhesive tape. The conducting wire 3 and the slider 5 are connected and fixed by means of the adhesive tape, facilitating mounting and dismounting.
