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
