Lining of a rattler, which working surface is equipped with wear-resistant metal components. The distance between the elements and the value of their projections over the surface of a plate is 0.3-0.35 of ball diameter and the ratio of vulcanized part and projecting part is 0.45-0.5. The metal parts are equipped with spines, which are curved in the form of a logarithmic spiral, which curvature increases from the beginning to the end of the spine and the angle between the tangent and the axis of symmetry is reduced, and located on both sides of the metallic elements. |
