The conveyor belt will rub against the rollers during use, and the friction between the two devices is generally unavoidable. However, in actual use, the friction between the conveyor belt and the idler roller will become large, so that the service life of both devices will be reduced. Therefore, the friction between the conveyor belt and the idler should be minimized during use.
The causes of wear between the idler and the conveyor belt mainly include installation errors, deformation of the roller frame structure, and roller corrosion.
1. The roller frame is not installed correctly; the conveyor belt can ensure its normal operation by generating a certain friction force under the support of the roller. Due to the improper installation, the axis of the idler roller is not perpendicular to the center line of the conveyor belt, and the conveyor belt is relatively slid relative to the idler roller, which aggravates the wear of the conveyor belt.
2. The adjustment of the centering roller is caused by the correction; when the centering roller is corrected, a certain inclination angle is generated. Due to the processing quality and corrosion, the rotation of the turret is not flexible, and the rotation can not be rotated in time, and the conveyor belt will be worn.
3. The rotation of the idler is delayed; due to the quality problems of the idler itself (such as poor sealing and inflexible bearing rotation), the rotation of the idler lags behind the running speed of the conveyor belt, causing relative sliding between the idler and the conveyor belt. And wear the conveyor belt.
