The main purpose of the high-elastic demountable couplings of the MOJ type is to connect the electric drive motor to the transmission shaft of the driven equipment.
The advantage of these couplings is that the replacement of the elastic elements wearing out during operation does not require disassembly of the coupling from the drive system. This applies to both the "U" type and the "F" segment. Access to the elastic elements is radial.
Furthermore, these couplings are characterized by significant capabilities for damping dynamic loads, especially under challenging operating conditions of the drive. They can be used in machines intended for operation in underground mines in zones a, b, or c of methane explosion hazard as well as A and B of coal dust explosion hazard, provided that the machines equipped with these couplings have undergone an EC type examination.
The primary application of MOJ type elastic couplings is the connection of an electric drive motor to a gearbox shaft in drives of conveyor and scraper systems, compressors, fans, and other devices.
