Gear-Flex Couplings Type ORD/ORS

Gear Couplings

High Torque Ratings

Octaforce ORD & ORS Series Gear couplings torque capacity exceeds the competition, and it allows smaller coupling size of increased service factor.

 

Large Bore Capacity

Octaforce ORD & ORS Series Gear couplings can accommodate large shaft diameters for given particular size of coupling compared to the competition, in most instances. That mean you can buy a smaller less expensive coupling and still get the proper rating for the equipment.

 

Interchangeability

Complete half coupling assemblies are interchangeable with any other half gear coupling with exposed bolt flange manufactured to AGMA standard. Octaforce replacement half couplings provide additional hub strength and lower gear mesh loads.

 

High Misalignment Capacity

Octaforce ORD & ORS Gear couplings are designed to accommodate a static misalignment of 1 ½° per gear mesh. The recommended operating misalignment is limited to 3/4° per gear mesh. Axial moment of connected shafts is also accommodated in these couplings.

 

 Lubrication System

Octaforce Special Grease (ORS) properties are designed/developed to resist separation of Base oil & thickner due to centrifugal forces encountered in Gear coupling. This benefits for the application –

  • Significantly extended relubrication intervals
  • Reduced maintenance cost
  • Superior lubrication
  • Increased coupling life

 

The location & size lubrication holes in the sleeve ensures that adequate grease is available at the gear mesh, where it is needed AGMA std. upto size 90.’O’ Ring retain Lubricant, during misaligned condition.

Double Engagement Couplings : TYPE - ORD

Double Engagement Couplings TYPE

Double Engagement Couplings: TYPE – ORD

Standard Double engagement couplings accommodate both angular and parallel misalignment or combination of both, as well as end float without imposing appreciable axial loads on adjacent bearings.

The exposed bolt design allows use of either open end or socket wrenches, which makes it the preferred design for most industrial applications.

Ideal for all standard applications including fans, overhead cranes, conveyors, steel and paper mill equipment’s.

Special requirements like limited end float, electrical insulation, Mill motor, Slide, Spacer, Brake drum, Shear pin, Shrouded bolt designs are supplied. Many designs can be created for “Unique” applications as well, contact Octaforce.
