Embodiment Construction

[0027] like figure 1 , figure 2 As shown, the present invention provides a bearing seat reconstruction structure and method for on-site monitoring of rolling bearing operation status, wherein the bearing seat 1 can represent the bearing seat of a rolling bearing in any mechanical system, and the bearing seat 1 and the test bearing 2 are matched. An annular groove 12 is processed in the circumferential direction on the inner surface, thereby providing enough arrangement space for the strain sensor 3 (such as Figure 5 As shown, the strain sensor 3 is pasted on the annular outer wall of the outer ring 21 of the test bearing 2). Moreover, the modification brought by the annular channel 12 to the various azimuth angles of the bearing seat is exactly the same, thereby ensuring that the modification to the bearing seat will not change the operating state such as the internal load distribution of the test bearing 2 . The cross-sectional shape of the annular channel 12 is arc-shape...

Abstract

The invention provides a bearing pedestal transformation structure and method for rolling bearing operation state in-situ monitoring. The structure is characterized in that an annular through groove is machined on the inner surface, used for cooperating with a test bearing, of a bearing pedestal in the circumferential direction, and the annular through groove can be connected with an outer ring ofthe test bearing to form an arrangement space; and a wiring hole is further machined on the bearing pedestal, and the annular through groove is communicated with the outer surface of the bearing pedestal through the wiring hole. The annular through groove ensures that the introduction of a groove does not change the original running state in a bearing, and the arc shape of the annular through groove avoids the occurrence of stress concentration in the transformation process of the bearing pedestal, thereby ensuring that the introduction of the groove does not cause the reduction of the structural strength. The frequency of a strain signal obtained in the test can be used for obtaining the rolling and sliding state in the bearing, and the amplitude and mean value of the strain signal can be used for obtaining the load and distribution condition of the bearing.

Description

technical field [0001] The invention relates to a structure and method for rebuilding a bearing seat for on-site monitoring of the running state of a rolling bearing, and in particular to a rebuilding method for a bearing seat for on-site monitoring of the running state of the rolling bearing in service environment. Background technique [0002] Rolling bearings are important components of mechanical transmission systems, and their internal rolling and sliding behavior, load distribution and other operating conditions directly affect the power transmission of the system. Most of the existing bearing seat reconstruction structures and methods for on-site monitoring of the running state of rolling bearings only use temperature probes to monitor the changes in the temperature parameters of the outer ring of the bearing in real time. Although this kind of temperature monitoring can avoid overheating of the bearing, it cannot timely and accurately understand the internal operatin...
