Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wear-resistant rotating member.

[0002]

2. Description of the Related Art Conventionally, a lagging material made of an ultra-hard wear-resistant material such as ceramic is attached or embedded on the surfaces of a conveyor belt and a driving pulley as rotating members.

The lagging material is used to prevent the surface from being worn.

The lagging material is formed in a substantially rectangular plate shape, and the back surface of the lagging material is embedded in the belt while the surface thereof is exposed on the surface of the conveyor belt.

[0005]

However, since the above-mentioned lagging material is in the form of a rectangular plate, the connection between the conveyor belt and the lining material does not become strong, and the lagging material is ore when the ore is transported. It has a drawback that it is easily peeled off by directly receiving an impact force such as.

Therefore, when the ore or the like comes into contact with the lining material from which the lagging material has been peeled off, the lining material is abraded, which shortens the life of the conveyor belt.

[0007]

Therefore, in the present invention, the upper portion is formed into a flat plate having a constant width and a narrow width, and a vertical plate-shaped embedded portion is integrally hung on the lower portion thereof, and the embedded portion is provided on the side surface of the embedded portion. A wear-resistant lagging material, which is integrally formed in an overhanging shape and has a recess in the rotation direction, is embedded in a lining material coated on a rotation base material that rotates in a fixed direction. The present invention provides a wear-resistant rotating member, characterized in that the longitudinal direction of the lagging member is substantially perpendicular to the rotating direction of the rotating base material.
