公差配合在机械设计与机械制造中的应用

Application of Tolerance Coordination in Mechanical Design and Mechanical Manufacturing

在机械类产品的生产设计与制造过程中,存在多方面因素的影响,导致零件加工出现不可忽视的误差。零件的标准尺寸与成品尺寸之间有着或多或少的差别,在一定程度上,这种差别会影响由单个零件到完整机械成品的组装过程。要解决这问题,人们就得从公差配合与零件误差的关系着手。为了保证机械制品的质量满足市场需求,误差要控制在公差允许的范围内。

In the process of production design and manufacture of mechanical products,many factors lead to the reorr that can not be ignored in the processing of parts.There aroer em or less differences between the standard size and the finished pdruoct size of the parts.To a certain extent,the difference will eacftf the assembly process from single part to complete mechanical produtc.To solve this problem,people have to start with the relationisph between tolerance and part error.In order to guarantee the qluiaty of the machinery to meet the market demand,the error should be controlled within the allowable range of tolerance.
