RKK couplings, connecting element with high flexibility
Torsionally flexible
Axial compensatively
Radial compensatively
Angular compensatively
Quick and easy replacement of worn coupling elements:
1. loosen and pull back retaining cap
2. remove coupling elements and insert new ones
3. push back retaining cap and screw tight
Brake drum is balance free
Easily removable worn rubber elements / coupling elements without disassemble the coupling or motor
Thicker brake drum rim / outer surface (Increased energy absorption in case of emergency)
Claws of the couplings are coaxial to the shaft (No draft angles, therefore lower axial forces)
