Tapered Grid Coupling

The steel tapered grid coupling is similar in nature to a steel gear coupling, except the connecting sleeve is replaced by a flexible chrome-vanadium alloy leaf spring grid. The steel hubs are cut with profiled slots, allowing the grid to engage circumferentially. The grid "springs" deflect under torque, distributing the peak torque load over a large angle of rotation. The inherent property of torsional softness allows the coupling to absorb shock loads.

Taper Grid Coupling

Vibration & Shock

Light Load

 Light Load

The grid contacts near the outer edges of the hub teeth. A long span between the points of contact remains free to flex under load.

Normal Load

 Normal Load

As the load increases, the distance between the contact points on the hub teeth is shortened, but a free span still remains to cushion the load.

Shock Load

 Shock Load

The coupling is flexible within its rated capacity. Under extreme overloads, the grid bears fully on the hub teeth and transmits full load directly.

 

Advantages

  • Overload conditions cause the grid element to shear, like a mechanical fuse
  • Grid can be changed "in place," saving time
  • Low maintenance
  • Quite operation
  • Allows for parallel / angular misalignment and permits end float
  • Torsional flexibility
  • Competitively priced
