Mechanical Parts: Grid Coupling

Characteristic & Merit:

We can get more favorable convenience and cost down by using thePTCTaper Grid Steel Flexible Coupling.

Parallel: The movement of the grid in the lubricated grooves accom-modates parallel misalign-ment and steel permits full function-ing of the grid-groove action in damping out shock and vibration.

Angular: Under angular misalignment, the gridgroove design permits a rocking and sliding action of the lubricated grid and hubs without any loss of power through the resilient grid.

End Float: Limited end float of driving and drivenmembers is permitted because the grid slides freely in the lubricated grooves.

Torsional Flexibility: Torsional flexibility is the advantage of PTC Taper Grid Couplings, providing flexible accommodation to changing load conditions.

1. Light Load

The grid bears near the outer edges of the hub teeth. The long span between the points of contact remains free to flex under load.2. 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 shock loads.

3. Shock Loads

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


1. When OVERLOAD, grid is assigned a part of safety pin and prevents breaking of the shaft or machinery part by cutting of grid.2. When the centering misalignment is too much, it can protect the relating machine by the virture of shearing of GRID or COVER or TOOTH.3. The life of all parts(Mechanical Seal and Bearing, etc) can be extended as a twice or more.4. Refair and check is needed scarcely, it costs short repairing time.5. Establishment. Assembly and maintenance are easy by getting rid of center misalignment.6. It always transmits the power fully(100%) and makes no noise.7. You can use it continually by changing accessories only.
