【摘要】：軸承作為機械設備中必不可少也是舉足輕重的零部件，在國民經濟和國防建設中具有重要的作用，目前我國軸承行業(yè)已經得到了飛速的發(fā)展，但在一些高端市場和特殊領域還要依賴進口，軸承的質量還需要不斷的提高。軸承的壽命和可靠性還不能完全滿足主機發(fā)展的要求。瓦軸集團作為中國軸承行業(yè)的領軍人物，雖然在產能上占據了一定優(yōu)勢，但在軸承質量方面還需要進一步提高，尤其是目前用戶對軋機軸承的抱怨不斷升高，軋機軸承頻繁出現質量問題，滾道剝落、軸承碎裂、保持架等問題影響了軸承的使用壽命，因此，我們有必要對影響軸承質量的原因進行深入研究，以提高軸承的使用壽命，贏得用戶的認可。 本文通過對瓦軸集團主導產品軋機軸承生產過程的質量控制研究，來提高軋機軸承的質量，解決軋機軸承壽命及可靠性低的問題，以適應市場的要求，提高企業(yè)的競爭力，并爭取早日實現國產軸承替代進口。 首先，本文對瓦軸集團的軋機軸承產品發(fā)展趨勢做了簡單的分析，并通過與國外軋機軸承的對比，明確存在的差距，，并分析了瓦軸集團質量管理現狀。其次，統(tǒng)計了軋機軸承在用戶中出現較頻繁的質量問題，通過對影響軋機軸承產品質量的原因進行分析，明確了設備的加工能力、軸承的設計方法是影響軸承質量問題的主要原因。并通過對設備的改造和軋機軸承產品的優(yōu)化設計，來提高軋機軸承的質量，實行了生產過程的質量控制。同時，通過對質量控制的持續(xù)改進情況進行探討，把軋機軸承的質量控制作為一項長期的質量行為來控制，以期得到穩(wěn)定的產品質量。 本文以質量管理理論為基礎，主要通過對鋼廠進行走訪獲得軋機軸承在用戶中使用的情況，并采用統(tǒng)計方法對影響軋機軸承壽命的原因進行分析，運用質量管理的相關知識對生產過程的質量進行控制。通過本文的研究，解決了瓦軸集團軋機軸承使用壽命低的問題，滿足了用戶的要求。
[Abstract]:Bearing, as an indispensable and important part in mechanical equipment, plays an important role in the national economy and national defense construction. At present, the bearing industry in China has been developing rapidly. But in some high-end markets and special areas have to rely on imports, bearing quality also needs to continue to improve. The life and reliability of the bearing can not fully meet the requirements of the development of the main engine. As the leading figure in China's bearing industry, although it occupies a certain advantage in production capacity, it still needs to further improve its bearing quality, especially in the light of the rising complaints from customers about rolling mill bearings at present. There are frequent quality problems in rolling mill bearings, such as raceway spalling, bearing fragmentation, cage and so on, which affect the service life of bearings. Therefore, it is necessary for us to deeply study the causes affecting bearing quality in order to improve the service life of bearings. Win the user's approval. In this paper, the quality control of rolling mill bearings, which is the main product of the rolling mill, is studied in order to improve the quality of rolling mill bearings and solve the problems of low service life and reliability of rolling mill bearings, so as to meet the requirements of the market and improve the competitiveness of enterprises. And strive for the early realization of domestic bearings to replace imports. Firstly, this paper makes a simple analysis on the development trend of rolling mill bearing products of the bearing group, and through the comparison with the foreign rolling mill bearings, it makes clear the existing gap, and analyzes the present situation of the quality management of the rolling mill bearing group. Secondly, the frequent quality problems of rolling mill bearings are analyzed, and the processing ability of the equipment is clarified by analyzing the reasons that affect the product quality of rolling mill bearings. Bearing design method is the main cause of bearing quality problem. By improving the equipment and optimizing the design of rolling mill bearing product, the quality of rolling mill bearing is improved, and the quality control of production process is carried out. At the same time, through the discussion of the continuous improvement of quality control, the quality control of rolling mill bearings is regarded as a long-term quality behavior in order to obtain stable product quality. Based on the theory of quality management, this paper obtains the use of rolling mill bearings in customers by visiting the steel mills, and analyzes the reasons that affect the life of rolling mill bearings by statistical method. Use knowledge of quality management to control the quality of production process. Through the research of this paper, the problem of low service life of rolling mill bearing of bearing shaft group is solved, and the requirement of customer is satisfied.
