[0002] Belt conveyors are used in power plants, docks, mines, etc. In belt conveyors, rollers are one of the important parts. During the operation of the conveyor, the friction between the belt and the roller causes the roller to vibrate, which makes the conveyor produce very loud noise during operation. A steel silent roller is proposed in prior art publication number CN205294076U. The roller includes: a roller tube, a bearing seat, a bearing, a roller shaft, a seal, a bearing clamp and at least one rubber ring. The inner diameter of all the rubber rings is larger than the diameter of the roller shaft. The roller disclosed in the patent is provided with at least one rubber ring in the steel roller tube, so that the vibration generated by the roller during operation can be absorbed by the rubber ring inside the roller tube, thereby reducing the noise generated by the vibration of the roller. However, a large part of the noise generated by the roller during operation is generated by the friction and extrusion between the bearing and the bearing seat, and adding a rubber ring to the roller tube is time-consuming, labor-intensive and difficult to operate, so it cannot solve the noise problem in actual production.
