General purpose gear couplings are made from titanium.

• True

• False

Rigid couplings are used to connect shafts that are precisely aligned.

• True

• False

Flexible couplings are used to connect shafts that need to be accommodated for their misalignment.

• True

• False

Flanged couplings are designed for use in low torque applications under 20,000 ft-lbs.

• True

• False

Sleeve couplings attach to shafts with locking setscrews.

• True

• False

Clamp rigid couplings allow for even distribution of clamping forces around the shaft.

• True

• False

Flexible couplings can accommodate up to 3 degrees of angular misalignment between shafts.

• True

• False

To reduce wear, some gear couplings are hardened

• True

• False

Manufacturers rate a coupling for its maximum misalignment capability.

• True

• False

Disc couplings transmit torque by a simple tensile force.

• True

• False
