Key Insights

• 😴 The design procedure of a bush pin type coupling involves selecting a suitable prime mover and coupling based on given parameters.
• 📶 Material selection for different components is crucial to ensure the coupling's strength and performance.
• 🫢 The use of a rubber bush in the coupling provides benefits such as shock absorption and proper alignment.
• 📔 Phd data books and standard coupling designations can be referenced for selecting appropriate dimensions and parameters.

Questions & Answers

Q: What is the purpose of a bush pin type coupling in machine design?

A bush pin type coupling is a flexible coupling used to transmit power between a prime mover and a driven end, allowing for slight misalignments in the shaft.

Q: How is the power to be transmitted calculated in the given numerical problem?

The power to be transmitted is calculated using the formula: Torque (Nm) = (Power (kW) * 1000) / (2π * RPM).

Q: Why is an electric motor selected as the prime mover in this scenario?

An electric motor is the most suitable prime mover because the given power requirement is not high, and the expected RPM is not large.

Q: How is the material selection done for different components of the coupling?

The material selection is done based on factors such as strength, stress limits, and application requirements. In this case, C30 steel is selected for shafts, keys, and bolts, while cast iron (GCI25) is chosen for hubs and flanges. A rubber bush is selected for shock absorption and proper alignment.
