Questions & Answers

Q: What is a knuckle joint and why is it used?

A knuckle joint is a mechanical joint used to connect a motor and a machine component. It allows for the transmission of rotational motion from the motor to the machine component.

Q: What are the failure criteria for a knuckle joint?

The failure criteria for a knuckle joint include tensile strength, crushing strength, shear strength, and bending strength. These factors must be considered in the design process.

Q: How is the knuckle joint assembled?

The knuckle joint consists of five components: I-end, forked end, pin, collar, and locking pin. The pin is inserted through the holes in the I-end and forked end, and the collar is used to lock the pin in place.

Q: How is the knuckle joint designed to withstand axial loads?

The design of the knuckle joint takes into consideration the axial load and the failure modes associated with it. Factors such as the diameter, length, and strength of the components are considered to ensure the joint can withstand the applied loads.
