【摘要】：陶瓷材料作為非金屬工程材料,在現(xiàn)代機械應用發(fā)展中占據(jù)越來越重要的地位,尤其是在制作陶瓷球作為軸承的滾動體方面,制作出高性能的陶瓷球軸承,提高了軸承的性能,廣泛應用于高速機床、航空航天、非磁性環(huán)境、耐高溫環(huán)境等方面。本論文以氮化硅陶瓷球為研究對象,以提高研磨陶瓷球的加工效率和精度為目標,通過理論研究、有限元仿真相結(jié)合,探索氮化硅陶瓷球在加工過程中受到的各項工藝影響,選擇工藝優(yōu)化方式來提高加工效率和精度。本論文的主要研究內(nèi)容包括:1.了解陶瓷的特性以及陶瓷球軸承的發(fā)展歷史和在國內(nèi)外的應用研究。2.陶瓷球的生產(chǎn)困難不僅僅包括對成型球坯的研磨加工,其制備毛坯球也是阻礙應用發(fā)展的問題,這里主要介紹國內(nèi)比較成熟的制坯過程和一些學者的改進方法。3.分析球在加工過程中的研磨軌跡和研磨流程,研究研磨過程中影響加工質(zhì)量的加工工藝參數(shù)和工藝裝備。4.通過熱態(tài)特性分析及熱力耦合分析,分析加工過程中在熱和力作用下的徑向和軸向變動量;通過對陶瓷球在研磨盤中的運動和靜力學分析,考慮對研磨板溝槽進行改進,并分析改進之后對球加工的影響。本論文考慮到工藝裝備對加工效率和精度的影響,并從實際情況選用合適的加工機床及從實際加工角度對加工進行了改進,確定研究成果的可靠性。
[Abstract]:As non-metallic engineering materials, ceramic materials play a more and more important role in the development of modern mechanical applications, especially in the production of ceramic ball as the rolling body of bearings, the production of high performance ceramic ball bearings, improve the performance of bearings, It is widely used in high speed machine tool, aerospace, non-magnetic environment, high temperature resistance environment and so on. In this paper, silicon nitride ceramic ball is taken as the research object, with the aim of improving the machining efficiency and precision of the grinding ceramic ball, the theoretical research is carried out. Combined with finite element simulation, the effects of various processes on silicon nitride ceramic ball in the process of machining are explored. The main contents of this thesis include: 1. Understanding the characteristics of ceramics and the development history of ceramic ball bearings and their application at home and abroad. 2. Difficulties in the production of ceramic balls. 2. Selection of process optimization methods to improve machining efficiency and accuracy. 1. Understanding the characteristics of ceramics and the history of development of ceramic ball bearings and their applications at home and abroad. It's not just the grinding of the molded ball billet, It is also a problem which hinders the development of application. This paper mainly introduces the relatively mature process of billet production in China and the improvement methods of some scholars. 3. The grinding track and grinding process of the ball in the process of processing are analyzed. The process parameters and equipment which affect the processing quality in the grinding process are studied. The radial and axial variations of the processing process under the action of heat and force are analyzed through the analysis of thermal characteristics and thermo-mechanical coupling. By analyzing the movement and statics of ceramic ball in the grinding disk, the improvement of the grooves of the grinding plate is considered, and the influence of the improvement on the machining of the ball is analyzed. In this paper, the effect of the process equipment on the processing efficiency and precision is considered. According to the actual situation, the suitable machining machine tool is selected and the machining is improved from the point of view of the actual processing, and the reliability of the research results is determined.
