An attachment point for fixation of lining to a blade of radial fan includes the blade and formed with pad with wear-resistant built-up material, main lining with through openings for fixation elements as bearing bushing and a rod with head at one end and threading at the other end for turning on a nut. To increase the life time of the lining, the unit is provided with additional lining, this comprises wear-resistant built-up material, at that the height of the rod head and the bearing bushing installed in the through opening of the blade is taken as equal to the thickness of the pad, additional lining is placed in the opening over the head of the rod and is taken with thickness equal to the height of the wear-resistant built-up material of the main lining, and the wear-resistance of the built-up material of the additional lining is taken as not smaller than the wear resistance of the built-up material of the main lining. |
