National Standard of the People's Republic of China Nominal torque series of the mechanicai couplingUDC621.825 GB3507---83 This standard applies to the nominal torque series transmitted by mechanical couplings for general purposes. When selecting the coupling torque, the values of series 1 should take precedence over those of series 2, and the values of series 2 should take precedence over those of series 3. The nominal torque value of mechanical couplings for general purposes should be selected from the following table. If the torque value is greater than the value specified in this standard, it can be selected according to the R20 series specified in (13321-80 "Preferred Numbers and Preferred Number Systems". The international unit system is preferred: 1kgl·m=9.80665N·m-10N·m Series National Bureau of Standards 1983-02-23 Issued 3 Series 2 Series 198312-01 Implementation GB3507-83 3 Series 10 000 25 000 100 000 160000 250 000 10 000 16 000 25 000 31 500bZxz.net 40 000 100000 125000 200 000 250 000 11 200 20 000 56 000 90 000 100000 112000 125000 140000 160000 180000 200000 224000 250 000 280000 630 000 Additional instructions: 315000 400 000 500000 800 000 GB3507—83 315000 355000 400 000 500 000 630 000 710 000 800 000 This standard is proposed by the Ministry of Machinery Industry of the People's Republic of China. 1 1000000 1600 000 2 series 1000 000 1250 000 1600 000 2000000 This standard was drafted by the Standardization Research Institute of the Ministry of Machinery Industry and the Xi'an Heavy Machinery Research Institute.
