Description

Technical Field

[0001] This utility model relates to the field of temperature detection technology, and in particular to a blade ring locking type bearing temperature sensor. Background Technology

[0002] Generator bearings, as key components for supporting and reducing friction, are crucial for the stable operation of the generator. Bearings are divided into integral and split types, and are typically placed in critical positions such as the outer ring of the rotor main shaft to support the main shaft or counteract radial forces. During normal operation, generator bearings should be within a certain temperature range. However, poor lubrication, uneven load, or material damage can cause the bearing temperature to become excessively high, thus affecting generator performance.

[0003] Currently, the sensors used in bearing temperature measurement are typically machined to match the bearing itself. This requires high machining precision for both the sensor and the bearing. Furthermore, when installing temperature sensors on bearings of different sizes, the sensor must extend into the bearing to varying lengths, resulting in high machining difficulty for both the sensor and the bearing, and poor sensor compatibility. In addition, existing sensor installation methods employ complex connections to link the sensor to the bearing, further increasing the complexity of sensor installation. Utility Model Content

[0036] Combination Figures 1 to 7 This invention provides a blade ring locking type bearing temperature sensor, including a sensor body 1, a blade ring 2, and a locking assembly 3. The blade ring 2 is sleeved on the sensor body 1 and disposed within the locking assembly 3, which is also sleeved on the sensor body 1. The locking assembly 3 is connected to the temperature measuring hole 4a of the bearing 4, and the end face of the sensor body 1 abuts against the inner wall of the temperature measuring hole 4a. Specifically, the sensor body 1 is fixed by clamping the blade ring 2. Pressure is applied to the blade ring 2 by the locking assembly 3, causing the blade ring 2 to deform under pressure, thus fixing the sensor body 1. After fixing, the end face of the sensor body 1 can closely adhere to the inner wall of the temperature measuring hole 4a of the bearing 4, accurately obtaining the temperature of the inner wall of the temperature measuring hole 4a, and realizing temperature detection of the bearing 4 during operation. Through this setting, the blade ring 2 is squeezed by the locking assembly 3, clamping and fixing the sensor body 1, thereby achieving quick installation and fixing of the sensor body 1, simplifying the installation process, and improving the efficiency of installation and maintenance. This fixing method allows for adjustment of the position of the sensor body 1 relative to the locking assembly 3 and the temperature measuring hole 4a of the bearing 4. It reduces the precision requirements for the machining of the sensor body 1 and the temperature measuring hole 4a of the bearing 4, while also enabling the sensor body 1 to be used with bearings 4 of different structural sizes, thus improving its versatility. Furthermore, by passing the sensor body 1 through the locking assembly 3 and the cutting ring 2, it ensures that the end face of the sensor body 1 directly abuts against the inner wall of the temperature measuring hole 4a, ensuring good heat conduction and efficient temperature measurement. Simultaneously, the sensor body 1 can accurately measure the temperature at the temperature measuring hole 4a of the bearing 4.

[0037] It should be noted that the specific structure of the locking assembly 3 is not limited here, nor is the method by which the locking structure applies pressure to the cutting ring 2. It is sufficient to allow the cutting ring 2 to be placed within the locking assembly 3, and to clamp the sensor body 1 by changing the structure of the locking assembly 3, such as multiple components abutting and pressing the cutting ring 2, or by the locking assembly 3 contracting to deform the cutting ring 2. Figures 4 to 7 In a preferred embodiment, the locking assembly 3 includes a first locking part 31 and a second locking part 32. The first locking part 31 is connected to the second locking part 32. The first end of the blade ring 2 abuts against the first locking part 31, and the second end of the blade ring 2 abuts against the second locking part 32. The first locking part 31 is connected to the temperature measuring hole 4a. Specifically, the first locking part 31 is connected to the temperature measuring hole 4a of the bearing 4, providing an installation base for the sensor body 1 and the second locking part 32. The first locking part 31 and the temperature measuring hole 4a can be connected by screws, rivets or interference fits, etc. The connection strength between the first locking part 31 and the temperature measuring hole 4a is sufficient to meet the operating requirements of the bearing 4 and the fixation of the sensor body 1. When the second locking part 32 is connected and installed with the first locking part 31, the distance between the first locking part 31 and the second locking part 32 is shortened, and the cutting ring 2 located between the first locking part 31 and the second locking part 32 is squeezed and deformed, so that the cutting ring 2 generates a clamping force on the sensor body 1, thus completing the fixation of the sensor body 1. The specific connection method of the first locking part 31 and the second locking part 32 is not limited here. In a preferred embodiment, the first locking part 31 and the second locking part 32 are screwed together. Specifically, the first locking part 31 is sleeved inside one end of the second locking part 32, and a thread is formed on the inner wall of the first locking part 31. This thread engages with the threaded part on one end of the second locking part 32, thus achieving the screw connection of the first locking part 31 and the second locking part 32. With this arrangement, the split structure of the locking assembly 3 simplifies the construction process. This connection method makes it easier to control the connection strength between the first locking part 31 and the second locking part 32, and facilitates the adjustment of the locking force. This ensures that the blade ring 2 has sufficient clamping force on the sensor body 1, while also avoiding the risk of over-connection of the first locking part 31 and the second locking part 32, which could lead to excessive deformation of the blade ring 2, damaging its own structure, and causing damage to the sensor body 1. This improves the connection strength and overall structural stability of the sensor body 1.

[0038] Combination Figures 3 to 6In a preferred embodiment, the first locking part 31 includes a first portion 311 and a second portion 312. The first portion 311 is sleeved on the sensor body 1 and connected to the temperature measuring hole 4a. The second portion 312 abuts against the surface of the bearing bush 4. The cutting ring 2 is disposed within the second portion 312. The second locking part 32 is connected to the second portion 312. Specifically, the first portion 311 is connected to the temperature measuring hole 4a to ensure the coaxiality of the sensor body 1 and the temperature measuring hole 4a. The second portion 312 provides installation space for the cutting ring 2. Preferably, the cross-sectional dimension of the second portion 312 is larger than that of the first portion 311 to ensure the structural strength between the first portion 311 and the second portion 312, while also forming installation space for the cutting ring 2 within the second portion 312. The second part 312 abuts against the surface of the bearing 4 to ensure the connection length between the first part 311 and the temperature measuring hole 4a. During the installation of the sensor body 1, the positional relationship between the second part 312 and the bearing 4 is used to determine whether the locking assembly 3 and the sensor body 1 are installed in the appropriate position, thereby improving installation accuracy and efficiency.

[0039] It should be noted that the specific structure of the cutting ring 2 is not limited here. It can be a cylindrical structure fitted onto the sensor body 1, which can clamp and fix the sensor body 1 by compression deformation through the first locking part 31 and the second locking part 32. In a preferred embodiment, the cutting ring 2 includes a ring body 21 and a first cutting edge 22. The first cutting edge 22 is located at the first end of the ring body 21, and a first chamber 31a is formed inside the first locking part 31. The first cutting edge 22 abuts against the inner wall of the first chamber 31a. Specifically, as shown... Figure 6 and Figure 7As shown, the specific structure of the first cutting edge portion 22 is configured such that its diameter gradually shrinks towards the first locking portion 31 along the axial direction of the cutting ring 2. That is, an inclined surface is formed on the outer side of the first cutting edge portion 22 relative to the axial direction of the cutting ring 2. By engaging the first chamber 31a formed in the first locking portion 31 with the inclined surface of the first cutting edge portion 22, when the cutting ring 2 is compressed and deformed, the inclined surface of the first cutting edge portion 22 moves towards the inner wall of the first chamber 31a. In the extreme state, such as when the compressive force applied to the cutting ring 2 by the first locking portion 31 and the second locking portion 32 reaches its maximum, the inclined surface of the first cutting edge portion 22 abuts against the inner wall of the first chamber 31a, forming a reaction force of the cutting ring 2 on the first locking portion 31 and the second locking portion 32, thus limiting the over-connection of the first locking portion 31 and the second locking portion 32. With this design, the first cutting edge 22 is more easily deformed during compression. When the first locking part 31 and the second locking part 32 apply a small compressive force, the first cutting edge 22 can deform, achieving efficient clamping of the sensor body 1. In addition, the cooperation between the first cutting edge 22 and the first chamber 31a ensures that the sensor body 1 is securely installed while avoiding over-connection of the first locking part 31 and the second locking part 32, preventing damage to the locking assembly 3, and improving the stability and service life of the overall structure.

[0040] In a preferred embodiment, the cutting ring 2 further includes a second cutting edge 23 located at the second end of the ring body 21. A second chamber 32a is formed within the second locking part 32, and the first cutting edge 22 abuts against the inner wall of the second chamber 32a. The function and principle of the second cutting edge 23 are similar to those of the first cutting edge 22, and will not be described again here. It should be noted that, in a preferred embodiment, the cutting ring 2 is configured with a left-right symmetrical structure, that is, the first cutting edge 22 and the second cutting edge 23 are symmetrically distributed on both sides of the ring body 21. With this configuration, the first locking part 31 and the second locking part 32 simultaneously apply pressure to both ends of the cutting ring 2, ensuring that the pressure effect at both ends of the cutting ring 2 is consistent, thereby improving the clamping uniformity of the cutting ring 2 and avoiding excessive stress on one side that could damage the structure of the cutting ring 2 or the sensor body 1.

[0041] In a preferred embodiment, a third chamber 312a is formed within the second portion 312, the second locking portion 32 is connected to the inner wall of the third chamber 312a, the ring 21 is located within the third chamber 312a, and the inner diameter of the third chamber 312a is larger than the diameter of the ring 21. Figure 5 and Figure 6As shown, after the second locking part 32 and the first locking part 31 are connected, the second locking part 32 is located in the third chamber 312a. The ring 21 is placed in the third chamber 312a. On the one hand, this ensures that there is a gap between the end of the second locking part 32 and the first locking part 31, further expanding the adjustable range of the locking connection. On the other hand, the inner diameter of the third chamber 312a is larger than the diameter of the ring 21, ensuring that the ring 21 has sufficient deformation space during compression, ensuring sufficient clamping force for the first cutting edge 22 and the second cutting edge 23, while releasing the energy present during compression and improving the stability of the overall structure. For example, when the cutting ring 2 is deformed by compression, the compression energy is equivalent to being stored in the cutting ring 2 in the form of elastic potential energy. The third chamber 312a provides sufficient deformation space for the cutting ring 2, thereby preventing the cutting ring 2 from being damaged by excessive compression.

[0042] In a preferred embodiment, a through groove 2a is formed on the blade ring 2, and the through groove 2a is arranged parallel to the axial direction of the sensor body 1. For example... Figure 7 As shown, the through groove 2a on the blade ring 2 is axially parallel to the sensor body 1. When the blade ring 2 is subjected to pressure, the reserved through groove 2a can increase the elasticity and deformation of the blade ring 2, further reducing the force required for locking. At the same time, the through groove 2a makes the blade ring 2 easier to deform, releasing the stress after locking.

[0043] Combination Figures 1 to 7 In a preferred embodiment, a limiting part 5 is also connected to the sensor body 1, the diameter of which is larger than the diameter of the sensor body 1. The limiting part 5 prevents the sensor body 1 from being excessively inserted into the temperature measuring hole 4a, and also prevents the end of the sensor, i.e., the end located outside the bearing 4, from entering the locking assembly 3. Specifically, during the installation of the sensor body 1, the sensor body 1 extends into the temperature measuring hole 4a along the locking assembly 3. After the end face of the sensor body 1 contacts the inner wall of the temperature measuring hole 4a, the limiting part 5 may abut against the locking assembly 3 or leave a gap between it and the locking assembly 3, preventing the end of the sensor body 1 from entering the locking assembly 3 and affecting the judgment of the installation status, while also facilitating the disassembly of the sensor body 1.

[0044] Combination Figures 3 to 5 In a preferred embodiment, the sensor body 1 integrates a temperature sensing element 6, which is connected to an optical fiber 7, which in turn connects to an external device. The optical fiber 7 and the temperature sensing element 6 work together to complete temperature measurement and temperature signal transmission, avoiding interference with traditional electrical signals, improving transmission efficiency and distance, and ensuring data reliability. In another preferred embodiment, the limiting part 5 is coaxial with the axis of the sensor body 1, and the optical fiber 7 passes through the limiting part 5 to connect to the temperature sensing element 6. This coaxial arrangement ensures that the optical fiber 7 is coaxial with the sensor body 1, preventing the optical fiber 7 from bending at the end of the sensor body 1 and affecting the locking operation.

[0045] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
