Description

Technical Field

[0001] The present application relates to the technical field of bearing detection, and in particular to a movable ultrasonic probe mounting device. Background Art

[0002] Angular contact ball bearings are widely used in mechanical transmission systems such as aircraft engine main shafts, gearboxes, and robot speed changers due to their small friction coefficient and excellent high-speed performance. For high-speed angular contact ball bearings, frequent collisions and friction between the rollers and the cage will cause the internal temperature of the bearing to rise. The rollers slide relative to the raceways under high-speed and light-load conditions, which reduces the orbital speed of the cage. Studies have shown that at high speeds, unstable bearing operation caused by frequent collisions between the rollers and the cage and friction between the roller raceways is often the main cause of bearing failure. Therefore, real-time measurement of bearing operating parameters (such as cage slippage and bearing film thickness) is very important, so the bearing seat often needs to be equipped with sensors such as ultrasonic probes.

[0003] In the related art, the installation position of the ultrasonic probe is inaccurate, resulting in deviations in the measurement results. Summary of the invention

In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0037] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

If present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0039] In order to prevent bearing failure, real-time measurement of bearing operating parameters is very important, so the bearing seat often needs to be installed with sensors such as ultrasonic probes. In order to ensure the measurement results, the ultrasonic probe needs to be installed directly above the contact area to align with the contact point. For angular contact ball bearings, under different load and speed conditions, the contact angle between the rolling element and the track will show a large difference, which directly leads to changes in the position of the contact area. Therefore, the existing ultrasonic probe has the problem of inaccurate installation position, resulting in deviations in the measurement results.

[0040] Based on this, an embodiment of the present application provides a movable ultrasound probe installation device, which can solve the above technical problems. The movable ultrasound probe installation device provided in an embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0041] See also Figures 1 to 4 As shown, a movable ultrasonic probe installation device provided in an embodiment of the present application is used to install an ultrasonic probe 510 on a bearing seat 410. The movable ultrasonic probe installation device includes a mounting sleeve 100 and a pressing plate 200. The mounting sleeve 100 is configured with a clamping portion 121 and a mounting hole 111 for mounting the ultrasonic probe 510; the pressing plate 200 is configured with a plurality of mating portions 210 arranged at intervals along a first direction; wherein the mounting sleeve 100 can be moved along the first direction so that the clamping portion 121 is clamped and matched with one of the mating portions 210; the first direction is perpendicular to the depth direction of the mounting hole 111. Figure 4 As shown, arrows are used to indicate the first direction and the depth direction of the mounting hole 111 , and the first direction is also the axial direction of the bearing.

[0042] The movable ultrasonic probe mounting device comprises a mounting sleeve 100 and a pressing plate 200. The mounting sleeve 100 is provided with a clamping portion 121 and a mounting hole 111 for mounting the ultrasonic probe 510. The pressing plate 200 is provided with a plurality of matching portions 210. When the ultrasonic probe 510 is used to measure the first bearing 420 on the bearing seat 410, the mounting position of the ultrasonic probe 510 is adjusted by adjusting the connection position of the clamping portion 121 and the matching portion 210, that is, the clamping portion 121 is clamped on the matching portion 210 at the corresponding position, so that the ultrasonic probe 510 is just above the contact area of ​​the first bearing 420, thereby ensuring the accuracy of the measurement result.

[0043] See also Figures 4 to 7 As shown, in one embodiment, one of the clamping portion 121 and the matching portion 210 is configured as a clamping block 1211, and the other is configured as a clamping groove 211 for clamping and matching with the clamping block 1211. Figure 4 In the illustrated embodiment, the clamping portion 121 is configured as a clamping block 1211, and the matching portion 210 is configured as a clamping groove 211. Through the clamping cooperation between the clamping portion 121 and the clamping groove 211, the detachable connection between the mounting sleeve 100 and the pressing plate 200 is achieved, thereby facilitating the adjustment of the position of the ultrasonic probe 510 and ensuring the accuracy of the measurement result. Of course, in other embodiments, the setting directions of the clamping portion 121 and the matching portion 210 can also be interchanged, that is, the clamping portion is configured as a clamping groove, and the matching portion is configured as a clamping portion, etc.

[0044] See also Figures 4 to 7 As shown, in one embodiment, the clamping block 1211 is constructed on the mounting sleeve 100; part of the pressing plate 200 is located above the mounting sleeve 100. By arranging part of the pressing plate 200 above the mounting sleeve 100, after the pressing plate 200 and the mounting sleeve 100 are docked, the mounting sleeve 100 can play a certain supporting effect on the pressing plate 200, thereby improving the fixing effect of the pressing plate 200 and the mounting sleeve 100. The clamping groove 211 is constructed on the pressing plate 200, and the depth direction of the clamping groove 211 is parallel to the depth direction of the mounting hole 111, and the clamping groove 211 does not penetrate the pressing plate 200.

[0045] That is, the mounting sleeve 100 is provided with a protruding clamping block 1211, and the pressing plate 200 is provided with a recessed clamping groove 211. The assembly direction of the clamping block 1211 and the clamping groove 211 can be along the depth direction of the mounting hole 111, for example, Figure 4In the illustrated embodiment, the pressing block can be docked with the installation sleeve 100 along the direction from top to bottom until the clamping block 1211 is completely clamped in the clamping groove 211. When it is necessary to adjust the matching position of the installation sleeve 100 and the pressing plate 200, the pressing plate 200 is moved from bottom to top again, so that the clamping block 1211 exits the clamping groove 211. After the pressing plate 200 moves to the position where the matching is required along the first direction, the pressing plate 200 continues to move downward, and the docking of the pressing plate 200 and the installation sleeve 100 is completed through the clamping matching of the clamping block 1211 and the clamping groove 211. Among them, the depth dimension of the clamping groove 211 is greater than the dimension of the clamping block 1211 along the depth direction, that is, the clamping block 1211 can be completely clamped in the clamping groove 211, thereby improving the connection reliability between the two.

[0046] See also Figures 4 to 7 As shown, in one embodiment, the cross-sectional area of ​​the clamping block 1211 gradually increases along the depth direction of the mounting hole 111 and along the direction from one side of the pressing plate 200 away from the mounting sleeve 100 to the other side of the pressing plate 200 close to the mounting sleeve 100.

[0047] For example, Figure 4 In the illustrated embodiment, the longitudinal section of the clamping block 1211 is a trapezoid, the longitudinal section of the clamping groove 211 is a rectangle, and the trapezoidal protrusion is clamped and matched with the rectangular groove. Among them, the groove width of the rectangular clamping groove 211 can match the width dimension of the trapezoidal clamping block 1211 at most places to ensure the clamping effect of the two. By clamping the trapezoidal protrusion in the rectangular groove at different locations, the position of the mounting sleeve 100 relative to the pressing plate 200 can be changed, that is, the position of the ultrasonic probe 510 relative to the bearing seat 410 and the first bearing 420 can be changed, so that the ultrasonic probe 510 is located directly above the contact area. By providing the trapezoidal protrusion, the trapezoidal protrusion can play a certain role in installation guidance during the assembly process, so as to facilitate the clamping block 1211 to be clamped in the clamping groove 211 along the depth direction of the clamping groove 211.

[0048] In other embodiments, the longitudinal cross-sectional shape of the clamping groove can also be adapted to the longitudinal cross-sectional shape of the clamping block. For example, when the clamping block is trapezoidal, the clamping groove is also trapezoidal, which can also facilitate the clamping of the two, and can increase the contact area between the clamping block and the clamping groove, further improve the connection effect between the clamping block and the clamping groove, thereby improving the fixing effect of the pressing plate and the installation sleeve. In another embodiment, the longitudinal cross-sectional shape of the clamping block can also be rectangular or triangular.

[0049] See also Figures 4 to 7As shown, in one embodiment, the installation sleeve 100 is provided with a plurality of clamping parts 121 arranged at intervals along the first direction, and each of the clamping parts 121 is correspondingly clamped and matched with one of the matching parts 210. By providing a plurality of clamping parts 121 to be matched with a plurality of matching parts 210 in a one-to-one correspondence, the connection area between the installation sleeve 100 and the pressing block can be increased, thereby improving the connection effect between the installation sleeve 100 and the pressing block, and improving the reliability of the entire device. It can be understood that the number of matching parts 210 is much larger than the number of clamping parts 121, that is, when the clamping parts 121 are clamped with the matching parts 210, there are always a plurality of matching parts 210 in an empty state, that is, not in a clamped state.

[0050] like Figure 4 As shown, in one embodiment, along the second direction, the two ends of the installation sleeve 100 are respectively provided with the clamping parts 121; correspondingly, the two ends of the pressing plate 200 are respectively provided with the matching parts 210; the second direction, the first direction and the depth direction of the installation hole 111 are perpendicular to each other. Figure 4 As shown, arrows are used to indicate the first direction, the second direction and the depth direction of the mounting hole 111. By providing the clamping portion 121 and the matching portion 210 at both ends of the mounting sleeve 100 and the pressing plate 200, the connection area of ​​the mounting sleeve 100 and the pressing plate 200 can be increased, thereby improving the connection effect of the two.

[0051] See also Figures 4 to 7 As shown, in one embodiment, the installation sleeve 100 includes a main body 110 and an extension portion 120 protruding from the main body 110 along the second direction, that is, the longitudinal section of the installation sleeve 100 is T-shaped, and correspondingly, the installation hole 111 is configured in the main body 110, and the clamping portion 121 is configured on a side surface of the extension portion 120 away from the main body 110. The cross section of the pressing plate 200 is U-shaped, with an opening configured in the middle, and matching portions 210 are configured at both ends of the pressing plate 200 along the second direction, and the installation sleeve 100 partially extends into the opening of the pressing plate 200 and is clamped with the matching portion 210 through the clamping portion 121.

[0052] like Figure 1 to Figure 2As shown, in one embodiment, the ultrasonic probe 510 includes two shells arranged along the depth direction of the mounting hole 111, and the two shells are sealed and connected. Detection elements such as ultrasonic sensors are arranged in the shells, and parameters such as the slip rate of the retainer and the film thickness of the bearing can be obtained through the ultrasonic sensor. A connecting line 520 is connected to one end of the ultrasonic probe 510, and a connecting end 521 is integrated at the end of the connecting line 520 away from the ultrasonic probe 510. In a specific embodiment, the connecting end 521 is an SMA male connector, which is used to be inserted into an SMA female connector to realize the transmission of radio frequency signals. Through the connecting line 520, the communication connection between the ultrasonic probe 510 and the data acquisition device is realized.

[0053] Since one end of the connecting wire 520 is integrated with an SMA male connector, its outer diameter is relatively large. In order to ensure that the mounting hole 111 has a fixing effect on the ultrasonic probe 510, the aperture of the mounting hole 111 is generally adapted to the outer diameter of the ultrasonic probe 510, that is, the aperture of the mounting hole 111 is limited. Therefore, it is impossible to assemble the ultrasonic probe 510 along the depth direction of the mounting hole 111 and make the mounting hole 111 accommodate the connecting wire 520 of the ultrasonic probe 510. Therefore, in one embodiment, refer to Figure 3 to Figure 4 As shown, the side surface of the mounting sleeve 100 along the first direction is configured with a wire groove 112 connected to the mounting hole 111. In this way, when installing the ultrasonic probe 510, the connecting wire 520 can be first inserted into the wire groove 112, and then the connecting wire 520 can be pulled upward, so that the ultrasonic probe 510 can be inserted into the mounting hole 111 along the movement direction from bottom to top, so that the ultrasonic probe 510 can be installed in the mounting hole 111 of the mounting sleeve 100. It can be understood that the groove width of the wire groove 112 is smaller than the outer diameter of the ultrasonic probe 510.

[0054] See also Figure 3 to Figure 4 As shown, in one embodiment, the extension direction of the wire groove 112 is not parallel to the depth direction of the mounting hole 111, that is, the longitudinal cross-sectional shape of the wire groove 112 is not a linear rectangle. Since the connecting wire 520 has a certain flexibility, even if the wire groove 112 is not a linear opening, the connecting wire 520 can pass through the wire groove 112 under the action of external force. Compared with a linear wire groove, by setting the wire groove 112 as a non-linear notch, the possibility of one end of the ultrasonic probe 510 extending into the wire groove 112 along its own radial direction can be reduced, that is, the possibility of the ultrasonic probe 510 shaking or displacing in the radial direction is reduced, and the reliability of fixing the ultrasonic probe 510 is improved. For example, in Figure 4 In the embodiment shown, the longitudinal cross-section of the wire groove 112 is approximately serpentine. In other embodiments, the longitudinal cross-section of the wire groove may also be stepped.

[0055] See also Figure 2 and Figure 3As shown, in one embodiment, the mounting sleeve 100 is configured with a step portion 113 at a position corresponding to the mounting hole 111, so that the mounting hole 111 is configured as a step hole, that is, the shape of the mounting hole 111 is adapted to the shape of the ultrasonic probe 510, and the ultrasonic probe 510 has a smaller outer diameter at one end, i.e., a small diameter end, and a larger outer diameter at the other end, i.e., a large diameter end. Figure 2 In the perspective shown, the outer diameter of the upper end of the ultrasonic probe 510 is smaller, and the outer diameter of the lower end is larger, and the transition between the small diameter end and the large diameter end forms a shoulder. Correspondingly, the mounting hole 111 also includes a small hole section and a large hole section, and the transition between the small hole section and the large hole section forms a step portion 113.

[0056] See also Figure 2 and Figure 3 As shown, in one embodiment, the surface of the step portion 113 on one side away from the pressing plate 200 is connected with an elastic member 130, and the elastic member 130 is used to provide a force in the direction of gravity. When the ultrasonic probe 510 is installed in the mounting hole 111 of the mounting sleeve 100, the upper end of the elastic member 130 abuts against the step portion 113, and the lower end of the elastic member 130 abuts against the shoulder of the ultrasonic probe 510, and the elastic member 130 is in a compressed state, so the elastic member 130 can apply a downward pressing force to the ultrasonic probe 510, so as to press the ultrasonic probe 510 tightly against the outer ring of the first bearing 420, thereby improving the measurement accuracy.

[0057] See also Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, the movable ultrasonic probe mounting device further includes a fixing member 300, the pressing plate 200 is detachably connected to the fixing member 300, and the fixing member 300 is used to connect with the bearing seat 410. Figure 3 As shown, the fixing member 300 is provided with a first connecting hole 310, and the fixing member 300 is connected to the bearing seat 410 through the first connecting hole 310. For example, the bearing seat 410 is provided with a first connecting shaft (not shown in the figure), and the first connecting shaft can be inserted into the first connecting hole 310 to achieve the connection between the bearing seat 410 and the fixing member 300; or, the bearing seat 410 is also provided with a connecting hole, and a fastener such as a bolt is passed through the second connecting hole 220 of the bearing seat 410 and the fixing member 300 to achieve the connection and fixation between the two.

[0058] like Figure 1 and Figure 4As shown, in one embodiment, a second connecting hole 220 is provided on the pressing plate 200, and the connection between the pressing plate 200 and the fixing member 300 is achieved through the second connecting hole 220. For example, the pressing plate 200 can be fixed to the fixing member 300 by passing a fastener through the fixing member 300 and the second connecting hole 220 of the pressing plate 200, thereby fixing components such as the ultrasonic probe 510 on the bearing seat 410.

[0059] In some embodiments, by rotating the first bearing, the contact position between the ultrasonic probe and the outer ring of the first bearing can be changed, thereby changing the test position. There is no need to frequently disassemble and assemble the ultrasonic probe, which reduces the frequency of disassembly and assembly of the ultrasonic probe, reduces the complexity of the measurement process, simplifies the detection process, improves efficiency, and ensures efficient acquisition of bearing operating parameters.

[0060] In some other embodiments, a temperature sensor is further provided in the ultrasonic probe, and the temperature of the outer ring of the first bearing can be measured by the temperature sensor, thereby enriching the measurement function.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
