Candy-Couplink

Candy Mfg. Co.'s new flexible shaft couplings are designed to enable easy connectivity between shafts of servomotors, stepmotors, AC/DC motors, gearboxes and encoders. The couplings are designed to transmit torque and rotational angle while absorbing angular, parallel offset and shaft end-play misalignments.

Parallel Offset Misalignment

Symmetrical Angular Misalignment

End-Play

Combined Misalignment

Misalignments are sometimes caused not only by equipment assembly, but also by vibration, heat expansion, wear of the support bearings, etc.

Selection Calculation

Calculate Motor Torque

Motor Torque (N.m) = KW x9550/rpm

1N-m = 8.856 in-lbs
KW= motor watt

Note: Larger coupling will have larger mass and inertia.

Coupling Attached Type

Setscrew Type: Units are bored with two setscrews placed at 90 degree. This low-cost type features a conventional attachment. However, the point of screw may cause damage to the shaft and may be difficult to remove.

Clamp Type: This type is clamped on the shaft by tightening the socket head cap screws. Attachment and removal is easy, causing no shaft damage.

Keyway Type: This type, like the setscrew type, features conventional attachment and is used for transmitting high torque.

Locking Type: This type is a self-contained, frictional shaft-hub, locking device. It is designed to be easily adjustable and release on a shaft, and can transmit high torque.

Danger

For safe operation, couplings and other parts must be secure and protected by covers.

Do not touch the product during operation.
Disconnect power to the connection while servicing or installation.
Use a torque wrench to secure setscrews and cap screws.
Do not exceed the rated maximum torque, misalignment factor or rpm designed for the unit.
