Basics of Couplings

The couplings are very useful in transmitting the torque from the motor to the driven machine. It is recommended to use flexible couplings that are capable of absorbing minor misalignments during the process of operating the device. The direct coupling is recognized when the axis of the electric motor is directly coupled to the axis of the driven load, without the need for any transmission element. When using any type of coupling, it is important to observe all the factors for effective operation, such as using suitable tools to assemble and disassemble the couplings, thus avoiding possible engine damage.

Direct coupling offers some advantages, has significantly lower cost, greater safety against any type of accident and still takes up less space. The maximum loads and speed limits reported in the couplings and engine manufacturers’ catalogs can not be exceeded. Leveling and alignment of the motor must be performed. Engines driven without coupled transmission elements must have their cotter pinned firmly or removed in order to prevent accidents.
