Causes and solutions of friction between conveyor belt and idler

The conveyor belt will rub against the conveyor idler during use. Generally, the friction between these two types of equipment is inevitable. However, in actual use, the friction between the conveyor belt and the conveyor idler will become larger, so that the service life of both equipment will be reduced. Therefore, the friction between the conveyor belt and the conveyor idler should be minimized during use. Let’s take a look at the causes and preventive measures of abnormal wear between the conveyor belt and the conveyor idler.

A. The causes of wear between the conveyor idler and the conveyor belt mainly include installation errors, deformation of the conveyor idler frame structure and corrosion of the idler. Organized as follows:

1. The roller frame is not installed correctly; the conveyor belt is supported by the roller to generate a certain frictional force to ensure its normal operation. Due to the incorrect installation, the axis of the supporting roller is not perpendicular to the center line of the conveyor belt, and the conveyor belt slides relative to the supporting roller, which aggravates the wear of the conveyor belt.
2. The self-aligning roller corrects and produces wear; when the self-aligning roller corrects, a certain inclination angle is generated. Due to processing quality and corrosion and other reasons, the rotation of the turret is not flexible and cannot be reset in time, which will wear the conveyor belt.
3. The rotation of the idler roller lags; due to the quality problems of the idler roller (such as inadequate sealing, inflexible bearing rotation, etc.), the rotation of the idler roller lags behind the running speed of the conveyor belt, causing relative slippage between the idler roller and the conveyor belt And wear conveyor belt.

B. The maintenance measures for the belt conveyor roller and the conveyor belt to prevent wear

1. First ensure that the entire conveyor belt is on a center line; secondly, the inclined rollers on both sides and the middle horizontal rollers have the same inclination angle, and all the intermediate rollers are on the same horizontal plane, so that all the rollers and the conveyor belt have a good Contact to ensure that each roller is evenly stressed.
2. Use self-aligning rollers as little as possible.
3. Strengthen the routine maintenance work of the rollers, and replace damaged rollers in time.
Conveyor belt wear is one of the more common failures, but if it is not taken seriously, it will often cause more serious accidents. Therefore, corresponding measures are taken to reduce the wear of the conveyor belt, extend the service life, and normal operation of the belt conveyor. Reducing maintenance costs has practical significance.
The above is about the cause and solution of the friction between the conveyor belt and the idler. I hope it will help you.
