WebMay 1, 2014 · designing a quick-return mechanism. The most common quick return ratio of the time of the cutting stroke to the time of the return stroke is about 3:2 (Ramamurti, 27). For the model to be considered a quick-return the desired time ratio should determine the radius of the crank and the length of the slider. WebCrank and slotted lever quick return motion mechanism: This mechanism is mostly used in shaping machines, slotting machines and in rotary internal combustion engines. In this mechanism, the link AC (i.e. link 3) forming the turning pair is fixed, as shown in fig. The link 3 corresponds to the connecting rod of a reciprocating steam engine. The …
