How Many Bolts are Required for Flange Coupling?

Question:

How many ½" diameter bolts in a 6" diameter bolt circle are required if the shear stress in each bolt is limited to 3000 psi?

Answer:

The number of bolts required is 20.

The shear stress in each bolt is limited to 3000 psi. The diameter of the bolts is 1/2". These bolts should be placed in a 6" diameter bolt circle.

The torque transmitted between two 2.5" diameter shafts is 15,000 in-lb. The cross-sectional area of a single bolt is 0.19635 in^2.

The shear stress formula was used to find the number of bolts required. The total force that can be applied to all the bolts is equal to 12000 lb.

Flange coupling is a type of coupling used in mechanical engineering that is used to connect two shafts.

This type of coupling is used in heavy machinery where the power transmitted is very high. A flange coupling is typically used in applications where the shafts are not close together, and there is a significant amount of misalignment.

The flange coupling is designed to transmit torque between two shafts. The torque is transmitted through a set of bolts that hold the two flanges together.

The bolts are placed in a circular pattern around the flange. The diameter of the bolt circle is an important factor in the design of a flange coupling.

The number of bolts required is determined by the shear stress in each bolt. The shear stress is the stress that is generated in the bolt when torque is applied to it.

The shear stress in each bolt is limited to a certain value, which is determined by the material properties of the bolt.
