Description

Technical Field

[0001] This application relates to the field of temperature measurement, and more particularly to a temperature sensor for a gearbox. Background Technology

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. It utilizes the characteristic that the resistance of a thermistor decreases rapidly as the temperature rises under a certain measurement power. By measuring the resistance of the thermistor, the corresponding temperature can be determined, thereby achieving the purpose of temperature detection and control.

[0003] In existing technologies, gearbox temperature monitoring sensors often face problems such as low temperature transmission efficiency, high assembly complexity, and difficulty in installation and debugging. Traditional sensor designs usually rely on an inefficient heat conduction medium to transmit the internal temperature information of the gearbox detected by the temperature probe to the thermistor. This transmission process is often slow and easily affected by external environmental factors, resulting in poor accuracy and real-time performance of temperature detection. Utility Model Content

[0004] To accurately detect temperature changes, this application provides a temperature sensor for a gearbox.

[0005] The temperature sensor for a gearbox provided in this application adopts the following technical solution: it includes a square ring installed on the outside of the housing, a connector is fixedly installed on one side of the housing, a temperature probe is fixedly installed on the other side of the housing, thermally conductive silicone is provided on the inner side of the temperature probe, a thermistor is wrapped on the inner side of the thermally conductive silicone, two leads are connected to the outer side of the thermistor, and one end of the two leads is connected to a terminal.

[0006] By adopting the above technical solution and setting thermally conductive silicone, the temperature inside the gearbox detected by the temperature probe can be quickly transferred to the thermistor. The thermistor's resistance decreases due to the actual heat, which changes the current. By measuring the actual current, the actual temperature of the gearbox can be detected, thus improving the temperature detection efficiency of this sensor.

[0007] Preferably, the outer side of the temperature probe is provided with external threads.

[0008] By adopting the above technical solution, it is easy to connect and install with the gearbox via external threads, and to better detect temperature.

[0009] Preferably, a partition block is fixedly installed on the inner side of the temperature probe, and the partition block is fixedly installed with the lead wire, with the two lead wires distributed on the outer sides of the partition block.

[0010] By adopting the above technical solution, the leads can be separated by the separator block, ensuring that adjacent leads remain in a non-contact state. This guarantees that the thermistor leads can smoothly transmit current, reducing the risk of leads becoming entangled due to movement or external interference. It effectively avoids problems such as poor current transmission or short circuits caused by entanglement. The thermistor leads can transmit current more smoothly and without obstruction on their predetermined paths, which not only improves the operating efficiency of the entire circuit system, but also significantly enhances the stability and reliability of the thermistor in complex environments.

[0011] Preferably, the two leads of the thermistor are connected to the terminal block by resistance welding.

[0012] By adopting the above technical solution, the current can be better transmitted between the thermistor and the terminal block through the lead wire.

[0013] Preferably, the wiring terminal is fixedly installed on the inside of the connector.

[0014] By adopting the above technical solution, the terminal blocks can be fixedly installed by setting connectors, making the plug-in installation more stable and better connecting the terminal blocks.

[0015] Preferably, mounting blocks are fixedly installed on both sides of the connector.

[0016] By adopting the above technical solution and setting the mounting block, a tight fit between the connector and the plug is ensured, effectively preventing detachment or separation caused by vibration or external force. It also greatly increases the firmness of the connection and installation, providing a solid guarantee for the long-term stable operation of the sensor. Through this structural design, we not only improve the detection performance of the sensor, but also ensure its reliability and durability in complex and ever-changing working conditions.

[0017] Preferably, a sealing gasket is provided on one side of the square ring.

[0018] By adopting the above technical solution, the sealing performance of this sensor is enhanced through the use of a sealing gasket.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] The thermally conductive silicone can quickly transfer the temperature inside the gearbox detected by the temperature probe to the thermistor. The thermistor's resistance decreases due to the actual heat, which changes the current. By measuring the actual current, the actual temperature of the gearbox can be detected, thus improving the sensor's temperature detection efficiency. The integrated design of the housing, square ring, and temperature probe reduces the need for welding, lowers assembly complexity, and achieves functional integration through structural optimization, reducing installation and debugging difficulties.

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0027] This application discloses a temperature sensor for a gearbox, including a square ring 2 installed on the outside of a housing 1. A connector 6 is fixedly installed on one side of the housing 1, and a temperature probe 5 is fixedly installed on the other side of the housing 1. Thermally conductive silicone 9 is provided on the inner side of the temperature probe 5, and a thermistor 10 is wrapped inside the thermally conductive silicone 9. Two leads 11 are connected to the outer side of the thermistor 10, and one end of the two leads 11 is connected to a terminal block 8.

[0028] Reference Figure 1 , Figure 4 The outer side of the temperature probe 5 is provided with an external thread 4.

[0029] By setting the external thread 4, it is easy to connect and install with the gearbox, and better detect the temperature. By setting the thermally conductive silicone 9, the temperature inside the gearbox detected by the temperature probe 5 can be quickly transferred to the thermistor 10. The resistance of the thermistor 10 decreases due to the actual heat, which changes the magnitude of the current. By measuring the actual current, the actual temperature of the gearbox can be detected, thus improving the temperature detection efficiency of this sensor.

[0030] Reference Figure 1 , Figure 4 A partition block 12 is fixedly installed on the inner side of the temperature probe 5. The partition block 12 is fixedly installed with the lead wire 11. The two lead wires 11 are distributed on the outer sides of the partition block 12. The two lead wires 11 of the thermistor 10 are connected to the terminal block 8 by resistance welding.

[0031] By setting the separator 12, the leads 11 can be separated, ensuring that adjacent leads 11 remain in a non-contact state. This ensures that the leads 11 of the thermistor 10 can smoothly transmit current, reducing the risk of the leads 11 becoming entangled due to movement or external interference. It effectively avoids problems such as poor current transmission or short circuits caused by entanglement. The leads 11 of the thermistor 10 can transmit current more smoothly and without obstruction on their predetermined path, which not only improves the operating efficiency of the entire circuit system, but also significantly enhances the stability and reliability of the thermistor 10 in complex environments.

[0032] Reference Figure 3 , Figure 4 Terminal 8 is fixedly installed inside connector 6.

[0033] By setting connector 6, terminal 8 can be fixedly installed, making the plug-in installation more stable and better connecting the connection end of terminal 8.

[0034] Reference Figure 2 Mounting blocks 7 are fixedly installed on both sides of connector 6.

[0035] By setting the mounting block 7, a tight fit between the connector plug and the connector 6 is ensured, effectively preventing detachment or separation caused by vibration or external force. It also greatly increases the firmness of the connection and installation, providing a solid guarantee for the long-term stable operation of the sensor. Through this structural design, we not only improve the detection performance of the sensor, but also ensure its reliability and durability in complex and ever-changing working conditions.

[0036] Reference Figure 1 , Figure 4 A sealing gasket 3 is provided on one side of the square ring 2.

[0037] By setting the sealing gasket 3, the sealing performance of this sensor is enhanced.

[0038] The implementation principle of a temperature sensor for a gearbox according to an embodiment of this application is as follows: This sensor integrates the housing 1, the square ring 2, and the temperature probe 5, thereby reducing the welding requirements and assembly complexity. Functional integration is achieved through structural optimization, reducing installation and debugging difficulty. By using high-performance thermally conductive silicone 9, the real-time internal temperature information of the gearbox accurately detected by the temperature probe 5 can be transmitted to the thermistor 10 extremely quickly and efficiently. During this process, the thermally conductive silicone 9 ensures the immediacy and accuracy of temperature transmission through its thermal conductivity. The resistance value of the thermistor 10 decreases accordingly with the actual heat received, and the change in resistance value dynamically adjusts the current flowing through it. The actual change in current is a key indicator for detecting the actual temperature of the gearbox, thus greatly improving the detection efficiency and accuracy of this temperature sensor for temperature changes. By setting the mounting block 7, the stability of the connecting plug and the connector 6 can be ensured, preventing detachment and increasing the robustness of the connection installation.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
