Abstract

The invention provides a DTSU paying-off pulley. The DTSU paying-off pulley comprises a base core, and a wear-resisting layer is arranged on the periphery of the base core; the base core comprises a hollow cylindrical middle shaft, and the middle portion of the middle shaft extends outwards to form a connecting ring; and the wear-resisting layer is subjected to bead welding to be arranged on the periphery of the connecting ring through a bead welding technology, and the wear-resisting layer is in a V shape of which the opening is horizontally outward. According to the DTSU paying-off pulley, the structure is simple, and the bead welding technology is adopted, so that the wear-resisting is directly connected with the base core, and connection is firmer. Elements of Mn, Mo, Cr, C, Ni and Fe are used for forming a novel hard material, and the material is high in hardness and better in wear resistance. Meanwhile, the material contains a large amount of Mo, Mo oxide products can be formed in the friction process, a certain lubricating effect on contact surfaces can be achieved due to existence of the Mo oxide products, and frictional losses of the material are reduced. More compositions of C and Cr exist, high chromium cast iron can be formed, and hardness and wear resistance of the material are improved.
