When using any coupling component, it is advisable to analyze some factors of great relevance, such as using appropriate tools and devices to enable assembly and disassembly of the couplings, and to prevent possible damages to the electric motor .
Direct coupling has some advantages, has a much lower cost, greater safety against any type of accident and still takes up less space. The maximum loads and speed limits set out in the manufacturer’s, couplings and electric motor catalogs can not be exceeded. It is necessary to level and align the motor.
Functional engines that do not have coupled transmission elements must have their key fixed securely or removed in order to act to prevent accidents. It is important that flexible couplings, which have the capacity to absorb minimum misalignments during the device intervention, are applied.
In this way, the couplings are very useful in transmitting the torque from the motor to the driven machine. The direct coupling can be connected at the exact instant in which the motor shaft is coupled directly to the axis of the driven load, without the need of using any transmission element.
