Description

TECHNICAL FIELD

[0002] At present, bearings are used in various mechanical equipment, and the performance and service life of the bearings are directly related to the quality of the entire equipment. Especially for bearings selected by large equipment, once assembled, the bearings cannot be easily replaced. In the process of selecting bearings for assembling equipment, the detection of bearings is generally manual detection or detection after trial assembly. In the detection process, the work intensity of workers is high, the work efficiency is low, and the detection effect is greatly affected by factors such as experience, responsibility, emotion, environment and physical condition of the detector, which greatly affects the detection effect. Therefore, the direct determining factor of the quality of the bearings is the bearing production enterprise, and the problem belongs to an uncertain factor relative to the quality system of the equipment.

[0003] In bearing production enterprises, the existing technology has adopted CCD video imaging technology to detect the size of the produced bearings. This detection method is mainly used in the bearing production line, and the bearings are detected in a static state, and the detector holds a CCD camera or fixes it on a device for detection. This method cannot detect the rotating dynamic effect of the bearing and cannot analyze whether there is a defect inside. Holding a CCD camera will also affect the accuracy of imaging due to shaking or position deviation. This production process cannot guarantee the safety and reliability of all bearings, which is a safety hazard for the bearing users.

[0004] For the bearing users, there is an urgent need for a dynamic detection device suitable for various bearings. For this purpose, the applicant has actively designed the technical solution to be introduced below, and has carried out simulation tests in the test center of the applicant under the condition of taking security measures, and the results prove that it is feasible. SUMMARY

[0006] The application is realized in the following way: the upper end of the disc base is fastened to the inner ring of the rotary bearing through fastening bolts 3; the pinion fixed on the rotary motor on the side of the disc base is engaged with the outer gear ring on the rotary bearing; a multi-prism test table is fixed on the middle part of the upper surface of the disc base, a lead screw motor is fixed in the center of the multi-prism test table, n groups of bearing support seats are welded on the outer conical surface of the multi-prism test table, the outer circumferential surface of the bearing on the bearing support seat is in contact with the outer circumferential surface of the inverted conical rubber block; the inverted conical rubber block and the pressure sensor are fixed on the upper part of the lead screw on the lead screw motor through the upper and lower lifting adjusting bolts; the CCD camera and the bearing noise monitor are fixed on the outer gear ring of the rotary bearing.

[0007] Further, a screw rod is arranged in the middle part of the disc type fixing seat of the bearing support seat, the outer circumferential surface of the inverted conical fastener arranged on the screw rod is in contact with the inner end surface of the four groups of clamping discs, and the left and right end surfaces of the spring are respectively in contact with the inner end surface of the inverted T-shaped groove and the end surface of the inverted T-shaped block.

[0008] The application has the following advantages and positive effects: ① the device has simple structure and is safe and reliable, and can meet the dynamic detection work of bearings of different specifications and sizes for equipment production enterprises; ② the device is complete in function, and can detect various data of bearings and analyze the health condition of the bearings through the CCD camera and the bearing noise monitor; ③ the device realizes dynamic detection in the rotating process of the bearing, is closer to the actual working condition than the traditional detector, and can obtain more accurate data.
