mechanical coupling
Has been developed at all levels of the standard coupling of our country has reached dozens of varieties, never were part of the flexible coupling and flexible coupling. Among the many standard couplings of how to combine the selection of those conditions of their purchase of even the correct coupling is a coupling purchase common problems faced by those who. JB / T 731l-94 can only be chosen to meet the computing needs, the content of certain limitations; JB / T 7937
95 (instead of GB / T 11227 89), is equivalent to using the same international standards ISO 4863 1984 "flexible coupling of users and manufacturers to provide technical information", its content and presentation and the actual situation of China's many gaps cloth, there is Some of the content ahead of that in recent cases, it is difficult to implement. In order to address the needs of the domestic purchase with reference to the relevant information and abroad with the national situation, developed a JB / T 8556-97 "choice of technical data coupling" mechanical industry standards in order to standardize the purchase of the coupling when the purchase by technical information provided to the factory the content and format, avoid shopping when there are no standard with a common technical language and the formation of chaos is a common and basic standards of professional couplings, one applicable to a variety of structural types of joint axis device option. The standard from the transmission system considerations, mainly by the driving machine, from the motivation, installation, working environment, marking and other components, applications and JB / T 73ll a 94 "mechanical coupling selection of calculation" supporting applications.
