Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of equipment state detection, in particular to a device for automatically detecting the wear of a ball mill bearing bush. Background Art
[0002] Real-time status detection of long-term rotating and easily worn bearings is crucial. It is usually composed of a flat circular piece with a relatively thin thickness and high measurement accuracy. The surface is slightly uneven and has lubricating grease particles attached to it. It is used to support and fix the main shaft of the main equipment. The function of the bearing is to support the rotation of the main shaft when the main equipment is running, and to bear the weight and wear of the abrasive and grinding media. At the same time, the gap between the main shaft and the bearing shell must be as small as possible to avoid the abrasive and grinding media from entering the bearing shell, thereby affecting the normal operation of the mill. During the long-term operation of the equipment, due to the gravity of the cylinder, all the weight will be concentrated on the bearing. Such working conditions make the bearing bear continuous and strong pressure, resulting in a relatively high wear rate. After the bearing is worn, it will rotate with gravity or other influences and there will be slight millimeter-level jitter affecting the reliable measurement of ordinary measuring devices. This wear will not only affect the normal operation of the equipment, but may also cause personal injury and even require shutdown for maintenance, which brings inconvenience to production and personnel safety. Therefore, we propose an automatic detection device for ball mill bearing wear to solve the above problems. Utility Model Content
