Embodiment Construction

[0015] combine figure 1 , the present invention is a method for detecting the parallelism and roughness of the axial end face of a bearing. The width end face of the bearing is defined as the axial end face of the bearing, and the outer diameter end face of the bearing is defined as the radial end face of the bearing. Since the bearing has an outer ring and an inner ring, and the width of the outer ring is either equal to the width of the inner ring or not equal to the width of the inner ring, the detection method of the present invention can detect the parallelism and roughness of the axial end surface of the outer ring of the bearing as well as Detect the parallelism and roughness of the axial end face of the inner ring of the bearing.

[0016] In this detection method, firstly, the bearing 7 to be tested is placed on the measuring platform 6. The lower end of the measuring platform 6 is connected to the main shaft 11 and is perpendicular to the main shaft 11. The main shaf...

Abstract

A method for testing the parallelism and roughness of the axial end surface of a bearing, in which the bearing to be tested (7) is placed flat on a measuring platform (6), and the side fulcrum (5) is aligned by moving the side fulcrum fork (4). Accurate the radial end face of the bearing under test, contact the sensor probe (8) with the axial end face of the bearing under test (7), make the measuring platform rotate one circle at a low speed through the motor (13), and the sensor probe against the axial end face of the bearing under test It also detects one circle and sends out a detection signal. The detection signal is input into the computer, and the parallelism or roughness of the axial end surface of the bearing under test can be detected through the comparison of the computer's pre-stored programs. For the parallelism or roughness detection of batches of small and medium-sized outer rings or batches of small and medium-sized inner rings and batches of small and medium-sized sleeve parts, the detection efficiency is higher, and the detection accuracy is more accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of bearing detection, in particular to a method for detecting the parallelism and roughness of the axial end surface of the bearing, which is suitable for small and medium-sized bearings. Background technique [0002] Most bearing manufacturers test the parallelism and roughness of the bearing axial end face manually. This manual detection method is inefficient and has large manual operation errors, which is no longer suitable for modern high-efficiency detection requirements. [0003] Bearings are usually composed of outer ring, inner ring, cage and balls. The axial end face of the bearing refers to the two parallel side end faces of the outer ring and the two parallel side end faces of the inner ring, and the two parallel side end faces of the finished bearing. The end face actually refers to the width end face of the bearing, therefore, the custom axial end face of the bearing refers to the width end face...
