Problems solved by technology
The integration of the temperature measuring element of this structure is low, and the structural change of the motor base is required to support it, which limits the design of the motor body structure. At the same time, when the temperature measuring element is damaged, all cables and sensors need to be replaced, which is economical. Poor performance, aesthetics, convenience, and integration

Embodiment Construction
[0011] In order to better understand the technical solution of the present invention, the following is a detailed description through specific embodiments:
[0012] See figure 1 , A motor bearing temperature measuring element of the present invention includes a temperature measuring sensor 1, a conversion head 2, a metal hose connector 3, a metal hose 4, a metal hose female connector 5, a double adapter male connector 6, an adapter seat Female 7 and end cable 8.
[0013] The temperature sensor 1 adopts a PT100 temperature sensor, which adopts a metal package, and is connected to a metal hose connector 3 through a conversion head 2. The conversion head 2 is threaded and installed with a spring, so that the temperature measurement sensor 1 can expand and contract relative to the conversion head, so that the temperature measurement sensor 1 can be closely attached to the measured part.
[0014] The metal hose connector 3 encapsulates the cable lead-out section of the temperature senso...

The invention discloses a motor bearing temperature measuring element which comprises a temperature measuring sensor, an adapter, a metal hose connector, a metal hose and a tail end cable connector assembly. The temperature measuring sensor abuts against a measured part. The metal hose connector enables a cable leading-out section of a sensor to be packaged in the metal hose, the metal hose is located outside a motor shell, the cable leading-out section of the sensor is led to a cable gathering part of a machine base, and then the cable leading-out section of the sensor is connected into the machine base through the tail end cable connector assembly to be connected. According to the invention, the purpose of separating a motor temperature measurement cable from a motor internal cable can be achieved.
Description
Technical field [0001] The invention relates to a bearing temperature measuring element used in the field of electric motors. Background technique [0002] The existing motor bearing temperature measurement element structure is to encapsulate the bearing-specific PT100 temperature measurement element in a metal or insulating sheath. The rear of the temperature measurement element is led out by a special cable and connected to the motor measurement outlet box for user monitoring. . The cable wiring of the temperature measurement element needs to pass through the inside of the motor. Considering the safety of cable wiring and the convenience of replacing the temperature measurement element, the inside of the motor base needs to be specially equipped with angle steel for wiring. The temperature measuring element of this kind of structure has low integration and requires structural changes of the motor frame to support it, which limits the design of the motor body structure. At the ...
