Problems solved by technology
[0004] The method of wired power supply and wired data transmission brings inconvenience to installation and maintenance, and there are certain potential safety hazards
In addition, when the temperature measuring device is rotated to fix the temperature measuring device on the shaft to be measured, the end of the resistance is incompletely in contact with the inside of the shaft to be measured or the contact force is too large, which may easily cause inaccurate temperature measurement or damage to the resistance

Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

The invention discloses an elastic contact type wireless temperature measurement mechanism, which is used for measuring the temperature of the internal part of a shaft to be measured. The elastic contact type wireless temperature measurement mechanism comprises a control end and a temperature measurement resistor fixed to the control end. The temperature measurement resistor comprises a spacing ring. The elastic contact type wireless temperature measurement mechanism also comprises a fastener and an elastic piece, wherein the fastener sleeves the temperature measurement resistor, and the elastic piece sleeves the temperature measurement resistor, and two ends of the elastic piece respectively abut against the spacing ring and the fastener, enabling the fastener to be movably disposed on the temperature measurement resistor. The fastener is provided with a fastening part, which cooperates with the shaft to be measured, enabling the elastic contact type wireless temperature measurement mechanism to be fixed to the shaft to be measured. When the tail end of the temperature measurement resistor abuts against the internal part of the shaft to be measured, the fastener is moved, enablingthe fastener to align with and be fixed to the fixed hole of the shaft to be measured, so that the problem that when the fastener is fixed to the shaft to be measured, the contact between the tail end of the temperature measurement resistor and the internal part of the shaft to be measured is partly done or excessively done, causing the temperature measurement to be not accurate or the reaction force at the tail end of the temperature measurement resistor to be excessively high and reducing the service lifetime of the temperature measurement resistor can be resolved.
Description
technical field [0001] The invention relates to a temperature measuring device, in particular to an elastic contact wireless temperature measuring mechanism. Background technique [0002] At present, in the process of industrial production, especially in the production process of oil refining, chemical industry and power generation enterprises, there are many bearing bushes of rotating system devices, especially the inside and outside of wind turbine bearings, large motor unit bearings, large high-speed blowers, steam turbines, compressors, Bearing bushes and thrust bushes such as hoods need to use thermal resistance temperature measuring devices for their temperature measurement. The existing temperature measuring device mainly uses wired temperature measuring method to measure temperature. In addition, in the temperature measuring contact mode, the platinum resistance is extended into the shaft to be measured and conflicts with the inside of the shaft to be measured, and t...
