JE/T9148-[999
The full standard is a revision of 2B902990 single-sex quick coupling. The difference between this standard and 2B19029:90 is that the force transmission nozzle is changed to symmetrical distribution, the pin hole length is improved, the working temperature range is expanded to 30-+120, the nominal non-[0000-3150000N·m is reduced, and the coupling with brake wheel is deleted. Appendix A coupling solution selection instructions: This standard is a replacement for ZDJ19029-90. This standard was proposed and drafted by the National Machinery Auxiliary and Accessory Standardization Technical Committee of the State Council. The drafting units of this standard are: Mechanical Science Research Institute, Zhandu Xinxing Ji Machinery Co., Ltd., and the main drafters of this standard are: Zhou Mingheng, Li Hongbo. The enterprise standard was issued for the first time in September 1990.
