Describe the function of a solid coupling

A solid coupling functions to rotate the shafts in opposite directions.

A solid coupling functions to separate two shafts for flexibility.

A solid coupling functions to connect two shafts together rigidly for power transmission.

A solid coupling functions to absorb vibrations in the shafts.

Describe the effect of thermal expansion on coupling alignment

Thermal expansion has no impact on coupling alignment

Coupling alignment improves with thermal expansion

Thermal expansion can cause misalignment in couplings due to differential expansion rates of the connected components.

Couplings expand uniformly with temperature changes

Describe coupling misalignment in a mechanical drive system

Is when the gears are too small

Is caused by excessive lubrication

Is a result of over-tightening the bolts

Occurs when the input and output shafts of the system are not properly aligned.

What cause shaft misalignment in a mechanical drive system

Improper installation, wear and tear, thermal expansion, or excessive loads

Lack of lubrication, over-tightening, incorrect material choice

Vibration, electrical interference, incorrect gear ratio

Corrosion, improper maintenance, inadequate power supply

Do couplings need lubrication?

Yes

Rarely

Sometimes

A bushed-pin type flange coupling is used

For intersecting shafts

When the shafts are not in exact alignment

For small shafts rotating at slow speeds

For parallel shafts
