Technical Field

[0001] The utility model relates to the technical field of bearing measurement, in particular to a bearing clearance measuring mechanism. Background Art

[0002] Bearing clearance refers to the amount of movement when the bearing is not installed on the shaft or bearing box, one of its inner ring or outer ring is fixed, and then the unfixed side of the bearing clearance moves radially or axially. According to the direction of movement, it can be divided into radial clearance and axial clearance. The size of the clearance during operation (called working clearance) affects the rolling fatigue life, temperature rise, noise, vibration and other performance of the bearing. Therefore, the bearing clearance of newly manufactured bearings basically needs to be measured. However, the current measurement of bearing clearance is done by manually placing it on a measuring machine, and then manually operating the machine to push the outer ring of the bearing up and down for measurement. The whole process is complicated and inefficient.
