Gear Coupling JDRO.MMZ-003 for Reliable Torque Transfer in Metro Applications

Coupling toothed ZhDRU.MMZ-003 (metro) is designed for connection of coaxial horizontal shafts and torque transmission at angular, radial and axial displacements of shafts. They are used to ensure stable operation of rail cars engaged in passenger transport. An initiative development, import substitution of the German KWD coupling. The design of the coupling allows to reduce time indices for mounting and dismounting of the coupling on the shafts of traction motors and gearboxes. Allows the use of oils of domestic manufacturers.
