AutoEngCalc - Engineering Calculators

Coupling Design Calculator

Select and size shaft couplings (rigid & flexible) based on torque, speed, misalignment and shaft diameters.

Recommended Coupling
Jaw Type Size 75
For 500 Nm, 1500 RPM, 1mm parallel misalignment

Shaft Coupling Selection

Featured: Rigid Flange, Flexible Jaw/Gear/Disc

Torque Capacity by Coupling Type

Rigid Couplings

• Flange, Muff, Sleeve
• No misalignment tolerance
• High torque, compact

Flexible Couplings

• Jaw (spider): moderate misalignment
• Gear: high torque, some misalignment
• Disc/Grid: high speed, zero backlash

Enter parameters and click Calculate

Coupling Types Comparison

Rigid

Perfect alignment, high torque.

Jaw/Spider

Shock absorption, moderate misalignment.

Gear

High torque, lubrication needed.

Disc/Grid

High speed, zero backlash.
