Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically to a novel rotary transformer and temperature sensor mounting structure. Background Technology

[0002] In motor control systems, both rotary transformers and temperature sensors play crucial roles. Rotary transformers are mainly used to accurately measure the rotor position and speed of the motor, while temperature sensors are used to monitor the temperature of core components such as motor windings and casing in real time and with precision.

[0003] When installing a rotary transformer and a temperature sensor, both need to be fixed to the rear end cover of the motor. However, current installation methods have some shortcomings. Installing the rotary transformer typically relies on complex mechanical structures to ensure coaxiality between the transformer and the motor shaft, resulting in a cumbersome and time-consuming installation process. Similarly, installing the temperature sensor is also cumbersome, and the accuracy of the installation position is difficult to guarantee. To address these issues, the inventor proposes a novel mounting structure for a rotary transformer and a temperature sensor. Utility Model Content

[0004] To address the current issues of cumbersome, time-consuming, and inaccurate installation processes for rotary transformers and temperature sensors, this invention aims to provide a novel installation structure for rotary transformers and temperature sensors.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel rotating transformer and temperature sensor mounting structure, including a motor rear end cover and a rotating transformer cover, wherein a rotating transformer body is disposed between the motor rear end cover and the rotating transformer cover, a rotating transformer positioning block is fixedly connected to the outer side wall of the rotating transformer body, a rotating transformer mounting position is provided on the side wall of the motor rear end cover, a rotating transformer limiting groove is provided on the inner side wall of the rotating transformer mounting position, the rotating transformer body corresponds to and cooperates with the rotating transformer mounting position, and the rotating transformer positioning block corresponds to and cooperates with the rotating transformer limiting groove.

[0006] Preferably, a rotary transformer sealing groove is provided on the side wall of the motor rear end cover and outside the rotary transformer mounting position. The end face of the rotary transformer cover corresponds to and mates with the rotary transformer sealing groove. A cover screw hole is provided on the side wall of the motor rear end cover and outside the rotary transformer sealing groove. A through hole is provided through the side wall of the rotary transformer cover, and the through hole corresponds to the cover screw hole and has the same diameter. A rotary transformer fixing screw is provided on the side wall of the motor rear end cover and inside the rotary transformer sealing groove. There are three rotary transformer fixing screws. When installing the rotary transformer body, the rotary transformer body is placed in the rotary transformer mounting position. The rotary transformer body installed in the rotary transformer mounting position can be limited and fixed by the rotary transformer fixing screw. Then, the rotary transformer cover is aligned with the motor rear end cover, and the through hole on the rotary transformer cover corresponds to the cover screw hole. By inserting the external screw into the through hole and mates with the cover screw hole, the rotary transformer cover and the motor rear end cover can be installed and fixed.

[0007] Preferably, a rotary transformer harness fixing position is provided on the lower part of the side wall of the motor rear end cover. The rotary transformer harness fixing position corresponds to and cooperates with the harness end of the rotary transformer body. The rotary transformer harness fixing position on the motor rear end cover is used to limit the harness inside the rotary transformer body, so as to make the harness neatly arranged and avoid the harness being messy. A slot is provided through the side wall of the rotary transformer cover, and an oil seal mounting position is provided on the end face of the slot. The rotary transformer cover is made of high-quality plastic material to form an effective elastic buffer zone with the rotary transformer body. When the motor is running, it can absorb the vibration and impact generated by the motor to reduce the impact on the rotary transformer body, thereby improving the measurement of the rotary transformer body. To ensure accuracy, extend service life, and guarantee long-term stable operation of the equipment, a temperature sensor mounting position is provided on the side wall of the motor rear end cover, on one side of the rotary transformer mounting position. This mounting position can accommodate a temperature sensor for the motor. During installation, the motor temperature sensor can be directly embedded into the mounting position, followed by the application of thermally conductive silicone. This simplifies the traditional installation process, eliminating the need for complex positioning and fixing operations, thus shortening installation time and improving efficiency. Furthermore, because the sensor is directly embedded in the specially designed mounting position, positional accuracy is reliably guaranteed, ensuring that the sensor can accurately sense the temperature of critical motor components, providing more reliable protection for the stable operation of the motor.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. In this utility model, when it is necessary to install the main body of the rotary transformer and the temperature sensor on the same motor rear end cover, a special temperature sensor mounting position is provided on the motor rear end cover. When installing the temperature sensor for the motor, the sensor can be directly embedded into the specially designed mounting position. Then, only thermally conductive fixing silicone needs to be poured in to complete the installation. This eliminates the traditional complicated installation steps and processes, greatly shortens the installation time, and reduces labor costs. Moreover, by embedding the sensor into the dedicated mounting position, the problem of inaccurate position determination in the traditional installation method can be avoided, ensuring that the sensor can accurately sense the temperature of the key parts of the motor and provide accurate data support for the effective triggering of the motor protection mechanism.

[0010] 2. In this utility model, when installing the main body of the rotary transformer, the main body of the rotary transformer can be placed in the corresponding installation position of the rotary transformer. The rotary transformer positioning block and the rotary transformer limiting groove cooperate with each other, so that the alignment can be quickly and accurately achieved during installation, and the installation position of the main body of the rotary transformer can be accurately determined. This simplifies the existing installation process and improves installation efficiency. By inserting external screws into the through holes and cooperating with the screw holes of the cover, the cover of the rotary transformer can be installed and fixed to the rear end cover of the motor, and the main body of the rotary transformer can be fixed again to improve the stability after installation.

The rotating transformer body 2 corresponds to and cooperates with the rotating transformer mounting position 5. The rotating transformer positioning block 11 corresponds to and cooperates with the rotating transformer limiting groove 8.

[0017] A rotary transformer sealing groove 4 is provided on the side wall of the motor rear end cover 1 and on the outside of the rotary transformer mounting position 5. The end face of the rotary transformer cover 3 corresponds to and fits with the rotary transformer sealing groove 4. A cover screw hole 12 is provided on the side wall of the motor rear end cover 1 and on the outside of the rotary transformer sealing groove 4. A through hole is provided through the side wall of the rotary transformer cover 3, which corresponds to the cover screw hole 12 and has the same diameter. A rotary transformer fixing screw 10 is provided on the side wall of the motor rear end cover 1 and on the inside of the rotary transformer sealing groove 4. There are three rotary transformer fixing screws 10.

[0018] By adopting the above technical solution, when installing the rotary transformer body 2, the rotary transformer body 2 is placed in the rotary transformer mounting position 5. The rotary transformer body 2 installed in the rotary transformer mounting position 5 can be limited and fixed by the rotary transformer fixing screws 10. Then, the rotary transformer cover 3 is aligned with the motor rear end cover 1, and the through hole on the rotary transformer cover 3 is aligned with the cover screw hole 12. By inserting the external screw into the through hole and cooperating with the cover screw hole 12, the rotary transformer cover 3 and the motor rear end cover 1 can be installed and fixed.

[0019] A rotary transformer harness fixing position 6 is provided on the lower side wall of the motor rear end cover 1. The rotary transformer harness fixing position 6 corresponds to and cooperates with the harness end of the rotary transformer body 2.

[0020] By adopting the above technical solution, the rotary transformer harness fixing position 6 on the motor rear end cover 1 is used to limit the harness inside the rotary transformer body 2, so that the harness is neatly arranged and the harness is not messy.

[0021] The side wall of the rotary transformer cover 3 is provided with a through slot, and the end face of the slot is provided with an oil seal mounting position 9.

[0022] By adopting the above technical solution, the rotary transformer cover 3 is made of high-quality plastic material, forming an effective elastic buffer zone between it and the rotary transformer body 2. When the motor is running, it can absorb the vibration and impact generated by the motor, thereby reducing the impact on the rotary transformer body 2, improving the measurement accuracy of the rotary transformer body 2, extending its service life, and ensuring the long-term stable operation of the equipment.

[0023] A temperature sensor mounting position 7 is provided on the side wall of the motor rear end cover 1 and on one side of the rotary transformer mounting position 5.

[0024] By adopting the above technical solution, the temperature sensor mounting position 7 can be used to install a temperature sensor for the motor. During the specific installation, the motor temperature sensor can be directly embedded into the temperature sensor mounting position 7, and then thermally conductive fixing silicone can be poured into it to complete the installation. This simplifies the traditional installation process, eliminating the need for complex positioning and fixing operations, thereby shortening the installation time and improving the installation efficiency. At the same time, since the sensor is directly embedded in the specially designed mounting position, the positional accuracy is reliably guaranteed, ensuring that the sensor can accurately sense the temperature of key parts of the motor, providing more reliable protection for the stable operation of the motor.

[0025] Working principle: When using this utility model, when it is necessary to install the temperature sensor for the main body 2 of the rotary transformer and the motor, the motor temperature sensor can be directly embedded into the temperature sensor mounting position 7 first, and then thermally conductive fixing silicone can be poured into it to complete the installation. This simplifies the traditional installation process, eliminates the need for complicated positioning and fixing operations, shortens the installation time, and improves the installation efficiency.

[0026] Next, when installing the main body 2 of the rotary transformer, the main body 2 of the rotary transformer is placed in the rotary transformer mounting position 5, and the rotary transformer positioning block 11 and the rotary transformer limiting groove 8 are engaged with each other. The rotary transformer fixing screw 10 can limit and fix the main body 2 of the rotary transformer installed in the rotary transformer mounting position 5. Then, the rotary transformer cover 3 is aligned with the motor rear end cover 1, and the through hole on the rotary transformer cover 3 is aligned with the cover screw hole 12. By inserting the external screw into the through hole and engaging with the cover screw hole 12, the rotary transformer cover 3 and the motor rear end cover 1 can be installed and fixed.

[0027] At the same time, the wiring harness on the main body 2 of the rotary transformer must be located within the wiring harness fixing position 6 of the rotary transformer so that the wiring harness is arranged neatly and avoids the wiring harness being messy.
