SWC universal coupling with whole fork
1 Scope
This standard specifies the classification, technical requirements, inspection rules, marking, packaging and storage of the SWC universal coupling with whole fork (hereinafter referred to as "the universal coupling").
This standard is applicable to the universal coupling connecting two transmission shaftings of different axes. Its swing diameter is 100 mm ~ 550 mm; nominal transmission torque is 2.5 kN·m ~ 1000 kN·m; and the axis break angle is 15° ~ 25°.
