Product Summary

pdf

A supporting roller comprises a skirt, for supporting a return side of a chain of a conveyor, and, coaxial with the skirt, a hub designed to rotate idly on a journal. Though in many ways satisfactory, the known rollers leave much to be desired when it comes to durability of operation.

One of the main problems with known rollers is that they tend, as they rotate about their respective journals, to pick up impurities, such as particles resulting from wear, and dirt in general, which greatly increase the resistance to rotation of the supporting roller on the journal. Because of the increasing resistance to rotation present between the known roller and the journal, the return side of the chain tends to skid on the surface of the skirt, resulting in accelerated wear of the parts in contact with each other. Another problem with known rollers, especially under the conditions of use at high speeds of rotation of the chain, is the noise of the coupling between the skirt and the chain. The problem addressed by the present invention is to devise a supporting roller with structural and functional characteristics such as to overcome the abovementioned problems cited with reference to the prior art.
