Couplings slide to accomodate misalignment

Paradrive oldham couplings for motion control applications comprise two aluminium hubs with drive tenons that mate with a floating centre member.

Paradrive oldham couplings for motion control applications comprise two aluminium hubs with drive tenons that mate with a floating centre member.

This design allows for easy sliding to accommodate misalignment.

These couplings have very light bearing loads as the only resistance caused by misalignment is frictional.

They also have the advantages of electrical isolation and relatively low cost.

The couplings accommodate angular and axial misalignment, but are especially useful in applications where parallel misalignment is present.

The replaceable centre disks are available in two materials to suit different applications.

Nylon disks are compliant to dampen vibrations and reduce noise.

Acetal disks are designed especially for precision applications.

They offer zero backlash and high torque capacity.

As the disks are the weakest and least expensive part of the coupling, they may be used as a mechanical fuse.

Paradrive couplings are offered in a choice of set screw or Nomar clamp-style hubs with outside diameters from 13 to 57mm and bores from 3 to 30mm.

The hubs are anodised for improved lubricity and increased life.

The couplings feature a balanced design for reduced vibration in higher rpm applications.

Common applications include encoders, positioning systems using servo and stepper motors, and other light duty drives.
