Smooth presentation on quick return motion mechanism

Very hahgd

1. gear based quick return mechanism enhancing efficiency in mechanical system

2. It is a four bar mechanism comprised of fixed link, crank, pin sliding in the slot and a sliding pair. Electric motor runs the driving pinion at a uniform speed. Pinion transmits its motion to gear. Gear has a pin on its surface which is confined to slide inside slot of crank. mechanism

3. mechanism

4. components DC motor

5. pinion

6. gear

7. Crank

8. sliding pair

9. screw and bolt

10. Application of quick return mechanism 1. employed in metal shearing machine 2. in embossing machine

11. 3. used in shaper machine to flaten the workpiece 4. used in mechanical actuator

12. Advantage :- 1. The process is automated. 2. The construction of mechanism is not complicated. 3. it can perform operations like cutting flatening etc. 4. the idle time is reduced because of the fast returning stroke.
