Rolling bearings have strict requirements on manufacturing precision and high technical specialization. Therefore, for most types of bearings that are easy to buy, it is more cost-effective to purchase than to repair. Only in the following cases, bearing repair is considered. problem.
(1) The failure modes of the bearings used in the ball mill are mainly the wear of the rolling surface, fatigue or fretting abrasion, especially the damaged parts are mostly cages or rolling elements, and the ferrule or gasket still has repair value;
(2) If the bearing fails or has failed, the part has no major damage, or the precious bearing must try to extend its effective use period;
(3) The bearing has slight damage, such as slight rust generated during the inventory period, and slight fretting abrasion caused by transportation. It is a pity that such repair is easy and abandon.
Bearing repair should not only consider its economic benefits, but also consider technical factors. The repairer fully understands the corresponding technical requirements of the bearing, and the structural, technical and material characteristics of the bearing and its parts, otherwise it is difficult to ensure that the bearing repair has the desired effect.
It is best to cooperate with professional bearing companies when repairing ball mill bearings. The reasons are: (1) the technical requirements of each process that can be repaired, and how to ensure the overall quality of the repaired bearings; (2) the use of professional bearings Many specialized experience of the factory, which can meet the process requirements reliably, efficiently and economically; (3) It is possible to order the tooling molds from professional bearing enterprises for repairing the business, which may be economical and save a lot of trouble; (4) Orders such as cages, rolling elements, rivets, etc. can be ordered from professional bearing companies, which may make the repair work simple, convenient and economical.
In addition, in the daily production, it is necessary to pay attention to the monitoring of the operation of the bearing, and to plan to repair the bearing before the failure, you can get twice the result with half the effort. At the same time, following a reasonable process, using efficient repair equipment and tools, and getting help from a professional bearing factory can help improve the economic efficiency of the company.
