A basic overview of the 1980s before the former Ministry of Machine, the Ministry of Textiles, Second Ministry of Machine couplings have a small number of several ministerial standards, after 20 years of development, to the 20th century, has been formed by the basic standards , product standards, quality grading standard components joint

First, the basic profile

      Before the 1980s, one of the former Ministry of Machine Building, Ministry of Textiles, Second Ministry of Machine couplings have a small number of several ministerial standards, after 20 years of development, to the 20th century, has been formed by the basic standards, product standards, quality grading standard coupling consisting of professional standards. Throughout the history of our standard couplings, coupling standard level, that national standards and machinery industry standards, is basically time to divide. Before 1989 both basic common standard couplings or product standard, almost all international and professional standards (ZB) between 1989-1990, after 1991 are all machinery industry standards (JB), 1999 onwards All the recommended standard (JB / T). Quality and Technical Supervision in 1998 after the abolition of professional standards and the national standards should straighten transformed, from March 1, 1999, professional standards (code ZB), clean up after rectification should be translated into other standards, all stop by professional standards and the use of national standards, the new system can not be a reference to the revised standard above criteria. While most industry professional standards and national standards required in 1999 before the relevant conversion industry department has been transformed, but there are a number of professional industry standards and national standards do not need to be converted for transformation. Therefore, the relevant competent authority has not transformed but still need to continue to use the professional standards unit standards and national standards were renumbered, that translated into an industry standard. Learn more beneficial couplings background selection, the level of the standard did not reflect the standard coupling itself and standard product level advanced. For a long time there is no coupling the centralized, resulting in the name of the coupling standard model chaos, advanced product structure, product standards constitute so many problems. China's current "national machine shaft and accessories for Standardization Technical Committee" with international standards TC14 counterparts, as an annex to the shaft coupling should be attributed to the TC14 as the standard committee, but in fact is not so. Second, the basis of common standards couplings
