The technology research on tractor transmission case 拖拉機變速箱殼體工藝方案研究
Seal - oil ; transmission case 變速箱殼
Gearbox is the key components in the automobile , and the case is key part in the gearbox 汽車變速器是汽車的關鍵部件之一,而變速箱殼體又是變速器中的關鍵零件。
Gearbox case is a complicacy detail . now its dimensional form and position parameter is measured ordinary by three - dimensional measuring machine . efficiency is very low 變速箱殼體是一個形狀復雜的大尺寸零件,目前國內外企業(yè)多數使用三坐標測量機對其尺寸和形位參數進行檢測。
Bj1036e2f1 light truck , developed by futian corporation , has continuously had batch cracking accidents on three shells including flywheel shell , clutch shell and gear - box shell from 1997 to 2000 . the rate of the accident is about 1 % . the accident ever not only made futian corporation certain economic loss , but also greatly affected sale of this type truck and security of customers " life and estate 福田公司開發(fā)的bj1036e2f1輕卡在1997 2000年連續(xù)發(fā)生三殼(飛輪殼、離合器殼和變速箱殼)批量破裂質量事故(約占該車型銷量的1 ) ,一度給公司造成較大的經濟損失,對該車型的市場銷售和用戶的生命及財產安全造成較大程度的影響。
This paper introduces design scheme of measurement system and establishes geometric parameter measurement patterns and functions of gearbox case , which are fit for the computer on - line automatic processing . measuring circuit and software are also introduced which are designed to carry out performance of the instrumentation 文中提出了變速箱殼體綜合檢測方案,給出了變速箱殼體幾何量測量方法,建立了變速箱殼體幾何量參數測量數學模型,推導了測量方程,對測量電路、實現(xiàn)整機功能要求的軟件結構給出了相關論述。
Now developing successfully “ gearbox synthetic inspection instrumentation ” can measure simultaneously the first and second bearing bore diameter and verticality parameters of gearbox case . information acquisition and data processing is controlled by computer . the instrumentation improves the inspection efficiency and meets the demand of mass - produced 本課題研制的變速箱殼體綜合檢測儀可實現(xiàn)在線檢測變速箱殼體一軸軸承孔直徑、二軸軸承孔直徑、一軸端面垂直度、二軸端面垂直度等幾何參數。
