H-SLD type grid coupling

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. 

Grid couplings use two slotted hubs with a steel grid running between them to transmit torque. The coupling flexes by allowing the grid to slide along the slots in the hubs. Grid couplings can only accommodate 1/3° misalignment and transmit torque from 422 in-lbs to 2,700,000 in-lb (3,656,555 Nm).

Tanso is pleased to be able to provide quality grid couplings covering a large number of industry standard sizes and lengths. The Tanso grid style coupling has proven itself in performance and popularity over a wide range of applications.

Tanso’s grid style coupling design has demonstrated its ability to dampen vibration by as much as 30% and can cushion shock loads that could cause damage to both the driving and driven equipment. The tapered grid spring design absorbs impact energy by spreading the energy out over the full length of the grid spring thus reducing the magnitude of the torque spikes.

The Tanso design uses a curved hub tooth profile which creates a progressive contact with the flexible grid spring as the application torque increases. This feature provides a more effective and efficient transmission of power in properly aligned couplings.

Tanso’s versatile design of industry standard hubs and grid springs for both horizontal and vertical cover styles allow Tanso couplings to be interchangeable with other industry standard grid couplings and components.

Proper grid coupling installation and maintenance can add to a longer coupling life. Grid spring replacement is simple and can be performed at a fraction of the cost and time of a complete coupling.
