May 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. Quick-return slider crank mechanisms.
Explain with the diagram working of crank and slotted lever.
. Crank 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. b Crank and Slotted Lever Mechanism Figure 3.11 The motion of link 4 in crank and slotted lever quick return motion mechanism can be taped through link 5 and can be transferred to ram. O2A1 and O2A2 are two positions of crank when link 4 will be tangential to the crank circle and corresponding to which ram will have extreme positions.

. A single slider crank chain is a modification of the basic four-bar chain. It consist of one sliding pair and three turning pairs. It is, usually, found in reciprocating steam engine mechanism. This type of mechanism converts rotary motion into reciprocating motion and vice versa. In a single slider crank chain, as shown the links 1 and 2..

Finite element analysis of crank and slotted lever quick return.
Crank and slotted lever quick return mechanism. To determine the return and forward stroke; 1 T i m e o f c u t t i n g s t r o k e T i m e o f r e t u r n s t r o k e = = 360 0 o r 360 0 In this study, the analysis was accomplished because of the three cases of the QRM. Whitworth quick return mechanism is consists of the following components:- 1] Crank:- The crank rotates with uniform angular velocity. It gets power from a pinion wheel or motor. 2] Slotted bar amp; Slider:- It is a bar with a slot for guiding a slider into it. The slider is connected to the end of the crank. For a crank and slotted lever quick return motion mechanism, the length of the fixed link is 300 mm and driving crank is 150 mm, and the slotted bar carrying the slider is 600 mm long. Which of the following are values of length of stroke LOS and quick return ratio QRR? QRR = 5 LOS = 600 cm QRR = 2 LOS = 60 cm Answer Detailed Solution Below.
Crank and Slotted Lever Quick Return Mechanism [Autosaved].
The quick return mechanism was modeled after the crank and slider arm, and this is present in its appearance and function; however, the crank is usually hand powered and the arm has the same rate throughout an entire revolution, whereas the arm of a quick return mechanism returns at a faster rate..
