Question

Quick return mechanism is an inversion of:

• A. Four bar chain
• B. Single slider crank chain
• C. Double slider crank chain
• D. Crossed slider crank chain

Hint:

The quick return mechanism is typically found in shaper and slotter machines and is an inversion of the single slider crank mechanism.

Answer 1

The Correct Option is B

The quick return mechanism is an inversion of the single slider crank chain. It is commonly used in shaper and slotter machines to convert rotary motion into reciprocating motion, with the return stroke being faster than the cutting stroke.
- A Four bar chain mechanism is a simple closed-loop mechanism but does not result in a quick return motion.
- A Double slider crank chain is a different type of mechanism that also does not produce quick return action.
- Crossed slider crank chain is a type of slider crank mechanism where the sliders cross each other, but it does not represent a quick return mechanism either.
Thus, the correct answer is (2), Single slider crank chain.
