Coupling Design Calculator | Torque, Shaft, and Stress Tool

coupling design Tool Formula:

Torque Capacity (T):

\[ T = F \times r \]

(where F = force acting on coupling, r = radius of coupling)

Shear Stress in Coupling Bolts (τ):

\[ T = \frac{T}{n \times r \times A_{b}} \]

(where T = torque, n = number of bolts, r = radius, A_b = bolt area)

Crushing Stress in Coupling (σ_c):

\[ \sigma_{c} = \frac{T}{d \times t \times r} \]

(where T = torque, d = hub diameter, t = flange thickness, r = radius)

The Coupling Design Calculator is an aid used by engineers, students, and technicians to develop safe and efficient power transmission couplings of shafts. Couplings are used to join rotating shafts to pass the torque, misalignment, and vibrations of mechanical systems. When stress limits are properly designed by proper coupling, failure and the downtime of the machinery will be avoided.

The user can key in the torque, shaft diameter, shaft speed, material strength, and the type of coupling (rigid or flexible). The calculator is used to determine shaft diameter, coupling size, transmitted torque, shear and bending stresses, and misalignment capability. Formulas used to transmit torque, analyse stress, or determine coupling size are explained in step-by-step format, which makes it simple to choose or design couplings to suit mechanical, automotive, and industrial systems.

Those units are supported: Nmm of torque, mm of dimensions, MPa of stress, rpm of shaft speed. This is the most suitable tool in the study of mechanical engineers, design engineers, students, and educators working with motors, pumps, gearboxes, and industrial machines to allow proper and dependable selection and design of couplings.
