This standard specifies the type, size, technical requirements, selection and marking requirements for the one-piece elastic coupling of the mixing transmission device. This standard applies to the connection between the output shaft and the transmission shaft of the reducer of the mixing transmission device. The transmission shaft must be supported on the double-fulcrum frame, and the coupling only plays the role of transmitting torque. This standard does not apply to single-fulcrum racks and use as couplings in kettles.
