TYPE - BVRG TYPE - BVRV TYPE - BVGD

Globally accepted by all engineering sectors for its unique shock absorbing and detuning properties, Resilient Couplings have earned the reputation of being ideal for drives where trouble-free operation is essential. The coupling acts as a mechanical fuse for the drive system, helps in altering the torsional vibration frequency, and prevents build up of resonance in the system. Ranging from various applications in Industries like power, steel, sugar, paper, mines, chemical, etc., where reliability is of paramount importance.

BVGD Coupling

  1. Select appropriate service factor F
  2. Calculate coupling Torque T (Knm), T = 9.55 x kW x F
    N

    Where kW = Drive rated power (kW) N = Speed (rev./min)

  3. Select coupling with the same or higher Torque.
  4. Check hub bore capacity.
  5. Check allowable speed.
