What kind of rolling bearing is worth repairing and what is the best way to repair it? Rolling bearings are mass-produced mechanical parts, and the manufacturing accuracy requirements are very strict, and the degree of technical specialization is very high. Therefore, for the vast majority of easy-to-buy bearing varieties, it should be more cost-effective to buy than to repair, only in the following cases , before considering the bearing repair problem: (1) For a large number of bearings of the same type used in large factories, the failure forms are mainly wear, fatigue or fretting of the rolling surface, especially the damaged parts are mostly cages or rolling elements, The ferrules or washers still have repair value; (2) large and extra large bearings are on the verge of failure or have failed without major damage to the parts, or expensive bearings must try to extend their effective service life; (3) some do Bearings that are difficult to buy have to be repaired without spare parts after failure, especially imported bearings; (4) There is slight damage to the bearing, such as slight rust during the inventory period, and slight fretting wear during transportation. It is a pity that such cases are easy to fix and discard. In addition to the economy, the repair of the bearing also has its technical nature, which requires the repairer to fully understand the corresponding technical requirements of the bearing, and the characteristics of the bearing and its parts in terms of structure, technology and material, otherwise it is difficult to ensure that the bearing is repaired. desired effect. 1. The economic benefits of bearing repair Generally speaking, the variety of bearings is small, the quantity is large, the price of a single bearing is high, or the structure of the bearing is simple. The larger the size, the lower the repair cost and the higher the economic benefit. In addition, monitoring the operation of the bearing, and repairing the bearing before it fails in a planned way, can get twice the result with half the effort. Following a reasonable process, using efficient repair equipment and tools, and obtaining the help of a professional bearing factory will help improve economic efficiency. Second, the benefits of cooperation with professional bearing companies. In the business of repairing bearings, if users can obtain the cooperation of professional bearing companies, they may get the following benefits: (1) The technical requirements of each repair process can be clarified, and how to ensure the overall quality of the repaired bearings; (2) It can be Using many specialized experiences of professional bearing factories, these experiences can meet the process requirements reliably, efficiently and economically; (3) It is possible to order work-carrying molds from professional bearing companies and borrow them for repair business, which may be more economical and save money. A lot of trouble; (4) accessories such as cages, rolling elements, rivets, etc. can be ordered from professional bearing companies, which may make the repair work simple, convenient and economical.
