Vertical mill rocker bearing chamber wear reason and the online repair steps

'Vertical mill rocker bearing chamber why wear? Vertical mill rocker bearing chamber after wear how to repair? Repair roller mill rocker bearing chamber wear steps have? 'These questions are constantly vertical mill radial bearings are often focus on topics, in order to we can better repair roller mill room rocker bearing wear, the Chinese bearing network on the basis of summarizing, share related knowledge. The main reason (vertical mill rocker bearing chamber wear 1) Normal fatigue wear, long-term collision and extrusion metal fatigue caused the rocker arm bearing chamber to cause plastic deformation. ( 2) Operation environment, the matching surface adhesion because of the dust, clearance and cause wear and tear. ( 3) With precision manufacturing technology, it is difficult to reach theory, form fitting surface has certain gap. Repair radial bearing chamber to wear ( 1) Remove after repair welding processing, maintenance time is long, laborious removal device, high cost, mating surface after repair welding gap still exists, and unable to deal effectively with stress concentration problem. ( 2) Brush plating repair technology, brush plating can't go beyond the requirements of critical thickness, and in the process of using brush plating easily shattered and use life is short. ( 3) Carbon nanotubes polymer materials, the materials is a high performance resin and carbon nano inorganic materials after polymerization technology to generate a function composite materials. Biggest advantage is the information impact resistant, corrosion resistance, wear resistance, high compressive strength, strong adhesion, machining performance inferior features, can be in the adhesion of metal, concrete, glass, PVC, rubber etc. Vertical mill rocker bearing chamber wear online repair case: a raw material for cement group problems larger low-frequency vibration grinding, and the vertical mill using about 8 - 10 years, the four roller rocker support part was badly damaged, serious wear is 20 ~ 30 mm, the early stage of the enterprises have adopted other metal repair process of bearing stop to repair, the overhaul, it found that the original repair downtime data once die forming secondary wear.
