Description

Technical Field

[0001] The utility model relates to the technical field of bearing temperature monitoring, and more specifically, to a combined bearing temperature monitoring and warning kit. Background Technique

[0002] In industrial production, as a key transmission component, the operating state of the bearing directly affects the performance and service life of the entire equipment. During the high-speed operation of the bearing, due to factors such as friction, poor lubrication, and excessive load, a large amount of heat is often generated. If this heat cannot be dissipated in time, it will cause the bearing temperature to rise sharply, which will further lead to bearing damage, equipment shutdown, and even more serious safety accidents. Therefore, it is particularly important to monitor and warn the bearing temperature in real time;

[0003] Most of the bearing temperature monitoring devices on the market currently adopt a single-point monitoring method, that is, only one sensor is installed at a certain position of the bearing for temperature monitoring. Although this method can initially meet the monitoring requirements, since the temperature distribution of the bearing is often uneven, single-point monitoring is difficult to comprehensively reflect the actual working state of the bearing. Therefore, we make improvements in this regard and propose a combined bearing temperature monitoring and warning kit. Summary of the Invention

[0037] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model

[0038] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments may be combined with each other

[0039] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings

[0040] Example 1, please refer to Figures 1 - 3 , a combined bearing temperature monitoring and warning kit, including two fixed seats 1. A connecting portion is provided between the two fixed seats 1. First threaded holes 202 are provided on both of the two fixed seats 1. First temperature sensors 2 are threadedly connected to the inner walls of the two first threaded holes 202. In this application, the two fixed seats 1 can be arranged on the outer side of the bearing through the connecting portion. By arranging the first temperature sensors 2 on both of the two fixed seats 1, the temperature of the bearing can be monitored at multiple points, so as to more comprehensively reflect the temperature distribution of the bearing, improve the accuracy and reliability of the monitoring. By monitoring the bearing temperature in real time and combining the preset warning threshold, a warning signal can be sent in time before the bearing fails, saving valuable time for equipment maintenance, reducing the failure risk and maintenance cost. The first temperature sensor 2 is used for monitoring the temperature of the outer ring of the bearing

[0041] The outer surface of the first temperature sensor 2 is provided with a thread and a first retaining ring 201. One side of the first retaining ring 201 contacts the fixed seat 1. The first retaining ring 201 can limit the installation of the first temperature sensor 2 to prevent the first retaining ring 201 from protruding too much and contacting the bearing to be detected during the detection process. Using threaded connection is beneficial to the disassembly and assembly of the first temperature sensor 2;

[0042] On the mutually remote sides of the two fixed seats 1, side grooves 106 are respectively formed. The position of the side grooves 106 corresponds to the position of the first threaded holes 202. The provision of the side grooves 106 can provide a receiving space for the exposed part of the first temperature sensor 2;

[0043] The connecting part includes a plurality of connecting members. The plurality of connecting members are all arranged between the two fixed seats 1 to realize the connection between the two fixed seats 1;

[0044] The connecting member includes two through holes 101 which are respectively formed in the two fixed seats 1. A first screw rod 102 is inserted and connected between the two through holes 101. A nut 103 is threadedly connected to the outer surface of the first screw rod 102. The first screw rod 102 and the nut 103 cooperate with each other to connect the two fixed seats 1 together.

[0045] Further, as Figure 1 and Figure 2 shown, on the mutually remote sides of the two fixed seats 1, protective plates 104 are respectively arranged. The outer surface of the through hole 101 passes through the protective plate 104. The protective plate 104 can play a protective role for the first temperature sensor 2.

[0046] Further, as Figure 2 shown, a wire routing hole 105 is formed in the protective plate 104. The wire routing hole 105 is used for routing wires of the first temperature sensor 2.

[0047] Embodiment 2 further optimizes the combined bearing temperature monitoring and warning kit provided in Embodiment 1. Specifically, as Figures 1 - 4 shown, two detection parts are arranged between the two fixed seats 1. The detection part includes a support member arranged between the two fixed seats 1, and a detection member is arranged on the support member. The support member can support the detection member.

[0048] Further, as Figures 1 - 4 shown, the support member includes two card slots 3 which are respectively formed in the two fixed seats 1. A support plate 302 is inserted between the two card slots 3. A connection hole 303 is formed in the support plate 302. Two insertion rods 301 are inserted into the inner wall of the connection hole 303. The mutually remote ends of the two insertion rods 301 are respectively fixedly connected to the inner walls of the two card slots 3. Such a setting enables the support plate 302 to be clamped between the two fixed seats 1.

[0049] Further, as Figure 4 shown, a support base 304 is provided on one side of the support plate 302. A threaded groove is formed in the support base 304, and a threaded rod 309 is threadedly connected in the threaded groove. One end of the threaded rod 309 passes through the support plate 302, and by rotating the threaded rod 309, the distance between the support base 304 and the support plate 302 can be adjusted.

[0050] Further, as Figure 4 shown, a limiting groove is formed in the support base 304, and a limiting rod 308 is inserted and connected in the limiting groove. One end of the limiting rod 308 is fixedly connected to the support plate 302. The cooperation between the limiting rod 308 and the limiting groove can limit the support base 304 to prevent the support base 304 from deflecting during movement;

[0051] A second threaded hole 305 is further formed in the support base 304. The detecting member includes a second temperature sensor 306 threadedly connected to the inner wall of the second threaded hole 305. A second retaining ring 307 is fixedly sleeved on the outer surface of the second temperature sensor 306. The second temperature sensor 306 is used for detecting the inner ring of the bearing.

[0052] Further, as Figure 4 shown, a groove 310 is formed in the support plate 302 away from the support base 304. One end of the threaded rod 309 away from the support base 304 is located in the groove 310, and a bearing is provided between the outer surface of the threaded rod 309 and the support plate 302. The arrangement of the groove 310 prevents one end of the threaded rod 309 away from the support base 304 from protruding.

[0053] Further, as Figure 4 shown, one end of the support plate 302 away from the support base 304 is arc-shaped, which is convenient for the support plate 302 to rotate.

[0054] Further, the inner wall of the clamping groove 3 is roughened to increase the frictional force between the clamping groove 3 and the support plate 302, so that after the two fixing seats 1 clamp the support plate 302, the situation of the support plate 302 rotating by itself is reduced.

[0055] Example 3 further optimizes the combined bearing temperature monitoring and warning kit provided in Example 1 or 2. Specifically, as Figure 1 shown, mounting seats 4 are fixedly connected to both sides of one of the fixing seats 1. An installation screw 401 is threadedly connected to the inner wall of the mounting seat 4. The cooperation between the mounting seat 4 and the installation screw 401 can mount the present application on a support object beside the bearing to be monitored, so that the present application and the circumference to be monitored do not directly contact during the monitoring process, thus not affecting its operation.

[0056] Further, as Figure 1As shown, a controller is installed inside one of the fixed seats 1, and an alarm 5 is also installed on the fixed seat 1. The alarm 5, the first temperature sensor 2, and the second temperature sensor 306 are all connected to the controller. Both the first temperature sensor 2 and the second temperature sensor 306 are non-contact temperature detection sensors, and the alarm 5 is used for high-temperature alarms.

[0057] When this application is in use, the support plate 302 is rotated, that is, as Figure 5 shown. At this time, the second temperature sensor 306 can be aligned with the inner ring of the bearing to be monitored. Before installation and use, the support plate 302 can be rotated horizontally. At this time, the second temperature sensor 306 is located between the two fixed seats 1, which can reduce the damage caused by being bumped during the carrying process.

[0058] The usage process of the combined bearing temperature monitoring and warning kit provided by the present utility model is as follows:

[0059] First, unscrew the first screw 102, and then the mounting seat 4 and the mounting screw 401 cooperate to install the corresponding fixed seat 1 on the supporting object beside the bearing to be monitored. At this time, the fixed seat 1 connected to the mounting seat 4 is located on one side of the bearing to be monitored. Then, the other fixed seat 1 is set on the other side of the bearing to be monitored, and the two fixed seats 1 are pre-fixed by the first screw 102 and the nut 103. Then, rotate the support plate 302, adjust the angle of the support plate 302 according to the actual situation, rotate the threaded rod 309 to make the support seat 304 move, adjust the position of the second temperature sensor 306 according to the actual situation, so that the second temperature sensor 306 is aligned with the inner ring of the bearing to be monitored. After adjustment, tighten the nut 103 to make the two fixed seats 1 clamp the support plate 302, and realize temperature monitoring through the cooperation of the second temperature sensor 306 and the first temperature sensor 2.
