由于鼓风机叶轮的驱动是通过贯穿附件机匣内25齿轮轴内套齿带动作高速运转,因而构成了内外径通道.外由磁力密封装置封严,内由O形圈封严,在高转速过程中伴随着不同程度的振动、窜动、比压、摩擦发热等诸多因素影响,导致滑油泄漏故障频发.为此,针对原采用完全互换法安装存在的故障分析原因,寻求提高装配精度与零件制造精度的关系,改进了与常规不同的选配、修配和调整的工艺方法进行装配控制,对排除泄漏故障有重要意义.%The driver for the impellers of a blower is operated at a high speed by a 25-gear shaft in accessory machine. Hence, it forms the in-side-outer diameters channels. The blower drive is encapsulated by magnetic sealing device from outside and an O-ring from inside. Affect-ed by vibrations, shifts, specific pressure, frictional heat and other factors, the lubrication leakage and the blower drive sealing device often breaks down while working at high speed. Thus, this paper analyzes the problems employing the method of complete switching installation. This paper aims to explore the relations between the improvement of the assembly accuracy and the precision of manufacturing. It is be-lieved that adopting improved methods to control assembling can contribute to the precision of manufacturing. This is of important signifi-cance for eliminating leaking problems.
