过去我国没有“圆锥公差与配合”方面的国家标准,为适应机械制造化日益发展的需要,保证圆锥联结件的互换、配套和提高产品质量,近几年。先后发布了GB157-89《锥度与锥角系列》,GB4096-83《棱体的角度与斜度系列》,GB11334-89《圆锥公差》,GB11335-89《未注公差角度的极限偏差》,GB1236-90《圆锥配合》等五项国家标准,为了推动新国标的贯彻,我们以问答形式连载介绍。 In the past, our country did not have “conic tolerance and cooperation” aspects of the national standards, to meet the growing needs of the manufacture of machinery to ensure the exchange of conical coupling, supporting and improving product quality in recent years. GB157-89 series of taper and cone angles, GB4096-83 series of angles and inclinations of prismatic bodies, GB11334-89 conical tolerance, GB11335-89 “limit deviation without tolerance angle”, GB1236-89 -90 “cone with” five national standards, in order to promote the implementation of the new national standard, we introduced a series of questions and answers.
