Centering principle and structural characteristics of roller
Clicks:12760 Date:4-12
Belt conveyor belt conveyor, also known, as a kind of important transport equipment, is widely used in metallurgy, mining, building materials, electricity, ports, food, light industry, machinery and chemical industries for the environment temperature of -25~40 that can carry the bulk materials, can also transport the goods. The utility model has the advantages of small noise, simple structure, and can be used for horizontal, inclined or mixed transportation, and can also be applied to the continuous moving machinery such as a ship loader, a ship unloader, a stacker and reclaimer, etc.. However, due to the influence of the factors such as the manufacture, installation and the misalignment of the joint, the deviation of the belt is inevitable. At present, there are many correction methods, the most commonly used and the most effective way is to use the center roller. The structure of a variety of self-aligning roller of offset in different ways, but the principle of roughly the same, namely when the rubber belt is driven by the self-aligning roller group deflection roller to produce a prompt recovery tape the equilibrium position of the friction force, so as to achieve the export of adhesive tape. The common self-aligning roller has the TD75 type groove shape centering roller, DTII type tapered roller, etc. a. Each of these two kinds of self-aligning roller has its advantages and disadvantages. The principle and structural characteristics of the core roller are introduced briefly, and the design is improved according to their respective characteristics.
When the center line roller and belt vertical to the central line, take the tape and roller any contact point, the belt line speed and the rotation speed of V, equivalent to V2 roller, because no relative sliding velocity between the two static friction, friction tape to the roller and the friction roller to glue with anti force equilibrium, the friction force and tape angle of central line is zero, so when the center line of the roller and the center line of the vertical belt, belt lateral force, the rubber belt is not roller automatic correction.
When the center lines of the roller and the tape is not vertical, a roller angle forward, take any point of contact, the belt line speed is V3, roller rotation speed is V4, the center lines of the roller and the tape is not vertical, the relative sliding speed. Between the two for dynamic friction. According to the direction of belt, roller tape to a forward F traction, the traction force can be decomposed into the roller rotating force F, and a lateral component of Fz, the transverse component to produce a reaction of F3 tape, F3 tape to shift to the right, which leads to the belt deviation. The method of adjustment is to move the right idler or move the left roller back to 5,6.
Therefore, the centering roller is provided with an error correcting force when the rubber belt deviates from the angle, which is designed and manufactured according to the principle.
