Embodiment 1

[0032] see Figure 1 to Figure 4 , the embodiment of the present invention provides a motor bearing state monitoring and early warning device: comprising a mounting seat 7 and a motor body 1 and a bearing seat 2 fixedly connected with the mounting seat 7, the bearing seat 2 is sleeved on the outside of the bearing of the output shaft of the motor body 1 ; The mounting seat 7 and the motor body 1 are existing mature technologies, and will not be described in detail here; the bottom of the bearing seat 2 is fixedly connected with the mounting seat 7, and its upper part is arranged in an annular sleeve outside the bearing, and the interior is hollow An annular placement groove is arranged and runs through the inner wall.

[0033] The internal movement of the placement groove is provided with a detection component 5 for monitoring the state of the bearing, and the internal movement of the bearing seat 2 is provided with several rotating components 3 and several connecting componen...

Embodiment 2

[0038] see Figure 1 to Figure 10On the basis of the first embodiment, the rotating assembly 3 includes a U-shaped bracket 301 located inside the placement groove, and a first spring 302 is provided between the surface of the U-shaped bracket 301 away from the bearing and the inner wall of the bearing seat 2. The first spring 302 It is fixedly connected to the U-shaped bracket 301 without being fixedly connected to the bearing seat 2. Because the first spring 302 is provided, the U-shaped bracket 301 tends to move relative to the bearing, and the first spring 302 can make the detection assembly 5 It can better contact with the bearing, so that the detection component 5 can better detect data; the surface of the U-shaped bracket 301 is penetrating and rotatably installed with a first support rod 303, and the end of the first support rod 303 is fixedly installed with a gear ring. 6. The gear 305 is connected by a transmission. A second support rod (not shown in the figure) is fi...

Embodiment 3

[0047] see Figure 1 to Figure 10 , on the basis of the second embodiment, a second spring (not shown in the figure) is arranged between the connecting rod 401 and the inner wall of the bearing seat 2, the second spring is arranged on the side of the connecting rod 401 close to the bearing, the second spring Not being fixedly connected with the connecting rod 401 and the bearing seat 2 will not affect the rotation of the connecting rod 401, but under the action of the second spring, the connecting rod 401 tends to move away from the bearing.

[0048] In this embodiment, it is preferred that when the elastic metal belt 501 rotates itself and rotates relative to the bearing under the action of the rotating roller 306 and the cylinder 402, its moving route is from below the rotating roller 306 through the cylinder 402 Above, and then below the next rotating roller 306, because the second spring is provided, the connecting rod 401 and the cylinder 402 have a tendency to move away ...

Abstract

The invention relates to the field of bearing monitoring, and discloses a motor bearing state monitoring and early warning device which comprises a mounting seat, a motor body and a bearing seat, the motor body and the bearing seat are fixedly connected with the mounting seat, the bearing seat sleeves a bearing of an output shaft of the motor body, and a placement groove is formed in the inner wall of the bearing seat in a penetrating mode. A detection assembly used for monitoring the state of the bearing and a plurality of rotating assemblies movably clamped with the detection assembly are movably arranged in the containing groove, and a plurality of connecting assemblies movably attached to the bearing seat are movably arranged in the bearing seat. Through cooperation of the rotating assembly, the connecting assembly, the detection assembly, the gear ring and the like, the detection assembly can be driven to move and rotate relative to the bearing, so that different positions of the detection assembly can make contact with different positions of the outer surface of the bearing for detection, and meanwhile the different positions of the detection assembly can detect the same position; and more accurate and more comprehensive temperature data can be obtained through data comparison.

Description

technical field [0001] The invention relates to the technical field of bearing monitoring, in particular to a motor bearing state monitoring and early warning device. Background technique [0002] Bearings are a kind of general equipment widely used in electric motors in electric power, metallurgy, aviation and other fields. They play the role of carrying and transmitting loads in the motor. Whether its running state is normal or not directly affects the performance of the entire motor. Therefore, It is very necessary to monitor and warn the running state of the bearing. [0003] Chinese Patent Publication No. CN210969432U, discloses a bearing temperature rise device for monitoring large stone saws, and relates to an online bearing monitoring system, including bearing outer ring, base, temperature sensor, power module, electromagnetic valve, microprocessor, indicator The lamp and the wireless communication module include a base, a rotating motor, and a bearing seat. The rot...
