【正文】 曲柄壓力機偏心機構設計 摘 要 中文摘要 。 鍛壓機械是為實現(xiàn)鍛壓工藝服務的。隨著生產的發(fā)展，鍛壓機械越來越廣泛的應用于國民經濟部門的工業(yè)生產中，除機械制造業(yè)本身外，動力機械工業(yè)、船舶、電機、電器、汽車、拖拉機、農業(yè)機械、機車車輛制造業(yè)、航空航天工業(yè)，以及與人們日常生活密切相關的家用電器、日用五金等輕工部門，均需要大量鍛壓機械為之服務；隨著科學技術的進步，需要更多、更好的各種鍛壓機械來進行各種鍛壓工藝，這就要求我們應用各種現(xiàn)代化的設計理論和計算方法，設計出自重輕、性能好生產率高的各類新型鍛壓機械，更好地 服務于祖國現(xiàn)代化建設中，對現(xiàn)代制造業(yè)極具現(xiàn)實意義。本設計鍛壓機械設備為機械式曲柄壓力機（采用偏心軸作為偏心機構）。 關鍵詞 : 曲柄壓力機，曲柄滑塊，偏心軸 連桿滑塊，滑動軸承 , [Crank Press eccentric design] [ABSTRACT] English summary 。 Fing machinery for the realization of fing technology services. With the development of production, fing machinery increasingly broad sectors of the national economy for the industrial sector, In addition to manufacturing its own machinery, power machinery industry, shipbuilding, electronics, electronics, electrical appliances, cars, tractors, agricultural machinery, vehicle manufacturing, aviation and aerospace industry, as well as closely related to people39。s daily life of household appliances, daily hardware and other light departments, which need a lot of fing machinery servicing。 With scientific and technological progress needs more, better the fing machinery for various fing process, This requires us to the application of modern design theory and the calculation method, from the light weight, The performance of various types of high productivity fing new machinery, to better serve China39。s modernization drive, Modern manufacturing highly realistic significance. Fing the design of mechanical equipment for mechanical crank press (using the eccentric shaft as eccentric institutions).
