Bearing clearance measuring device

Abstract

The invention relates to a bearing clearance measuring device. A pair of symmetrical supports is placed on the working chopping board. And two sets of mutually parallel angular contact bearings (an inner spacer ring and an outer spacer ring are arranged between the two bearings) are fixed through bracket fastening screws. Two pairs of jacks are arranged below the parallel support, and the working clearance of the angular contact bearing is measured by adjusting the lifting heights of the two pairs of jacks below the parallel support. The upper set screw in the support is matched with the lower bearing outer ring and is fastened with the bearing outer ring through a bolt, the jack on the cutting board is matched with the bearing inner ring at the same time, the dial indicator is read, and the bearing clearance can be effectively measured.

Description

Technical Field

[0001] The present invention relates to a measuring device for bearing clearance. Background Art

[0002] The functions of a bearing measuring device mainly include two aspects. One is to provide a bearing detection platform; the other is to enable an angular contact bearing to have an accurate detection result under relatively precise auxiliary detection conditions to ensure the assembly accuracy.

[0003] Patent Search: Invention Patent "A Comprehensive Bearing Clearance Measuring Device", Patent Authorization Number CN201811063102.2. The present invention discloses a comprehensive bearing clearance measuring device, including a loading control mechanism for bearing clearance measurement. The loading control mechanism includes a frame, on which there is an installation hole. A bearing clamping device for radial bearing clearance measurement and a bearing clamping device for axial bearing clearance measurement can both be adaptively installed in the installation hole to achieve the comprehensive measurement of radial and axial bearing clearances. It has the following advantages: when performing radial or axial clearance measurement, only the installation method of the measured bearing needs to be changed, and there is no need to change the machine to achieve the comprehensive measurement of axial and radial clearances; it has a precise measurement function that existing instruments do not have. Summary of the Invention

[0004] The purpose of the present invention is to provide a measuring device for bearing clearance, with a reasonable design structure, reliable performance, convenient operation, which can limit the degrees of freedom of the bearing, can improve the operation and measurement level to a large extent, has high measurement accuracy and accurate measurement, eliminates the inability to measure the clearance of angular contact bearings before installation, and after installation, the phenomenon of assembly rework caused by the measured bearing being too small or too large is avoided, improving the installation accuracy of the equipment and the operation efficiency.

[0005] The technical solution adopted by the present invention is a measuring device for bearing clearance, including a flat anvil. On the top surfaces of both side parts of the flat anvil, brackets are vertically arranged respectively. On the inner bottom parts of the brackets, a jack is vertically arranged respectively. On the inner top parts of the brackets, a set screw is vertically arranged respectively; between the inner parts of the brackets and the set screws, two angular contact bearings are horizontally arranged at upper and lower intervals. An outer bearing spacer is arranged between the outer rings of the two angular contact bearings, and an inner bearing spacer is arranged between the inner rings of the two angular contact bearings. The lower end of the set screw is in contact with the top surface of the outer ring of the upper angular contact bearing, and the upper ends of the two jacks are in contact with the bottom surface of the inner ring of the lower angular contact bearing. A dial indicator is arranged on the top surface of the inner ring of the upper angular contact bearing.

[0006] On the working anvil, there is a pair of symmetric brackets. Two sets of angular contact bearings parallel to each other are fixed by bracket set screws (there are inner and outer spacer rings between the two bearings). There are two pairs of jacks under the parallel brackets, and the lifting height of the two pairs of jacks under the parallel brackets is adjusted. The upper set screw inside the bracket cooperates with the outer ring of the lower bearing and is fastened to the outer ring of the bearing through bolts. The jacks on the anvil cooperate with the inner ring of the bearing at the same time. By reading the dial indicator, the bearing clearance can be effectively measured.

[0007] From the perspective of using the bearing clearance measuring device, the measurement of angular contact bearings achieves the purpose of judging the quality of bearing clearance. Through the use of angular contact bearings on the production line, all qualified products can meet the requirements of on-site working conditions after measurement. Under the condition of ensuring good bearing lubrication, the tracking working state of angular contact bearings is normal, indicating that the bearing clearance detection device has achieved the expected effect. The present invention is applicable to the detection method of bearings in high-speed wire rod roll boxes and cone boxes with the function of bearing clearance detection and installation requirements of the same type, and the accuracy of clearance detection is high. Brief Description of the Drawings

[0008] Figure 1 It is a front view structural schematic diagram of the present invention. Embodiment

[0009] A bearing clearance measuring device, as Figure 1 shown, includes a flat anvil 1. On the top surfaces of both side parts of the flat anvil 1, brackets 2 are vertically arranged respectively. On the inner side of the bottom surface of each bracket 2, a jack 3 is vertically arranged respectively. On the inner side of the top end of each bracket 2, a set screw 4 is vertically arranged respectively; between the inner side of the bracket and the said set screw, two angular contact bearings are horizontally arranged at upper and lower intervals. An outer bearing spacer ring 5 is arranged between the outer rings of the two angular contact bearings, and an inner bearing spacer ring 6 is arranged between the inner rings of the two angular contact bearings. The lower end of the set screw contacts the top surface of the outer ring of the upper angular contact bearing. The upper ends of the two jacks contact the bottom surface of the inner ring of the lower angular contact bearing. A dial indicator 7 is arranged on the top surface of the inner ring of the upper angular contact bearing.
