Crank and Lever Reciprocating Mechanism

This paper deals with the analysis of crank and slotted mechanism that converts rotary motion into reciprocating motion at different rate for its working stroke and return stroke. A CAD model of synthesized link lengths has been prepared to simulate the mechanism and to specify the accurate path of the mechanism which would provide the actual position of the slider against the crank rotation. Software package will be helpful for manufacturing industries to get accurate performance in minimum manufacturing cost. Software also provides the optimized scheme of tolerance for desired permissible variation in output. In this mechanism we are using spraying pump as an application. With help of spraying pump we can wash any car. It reduces human effort. As we know spraying pump can be used in various industries. We can also use it for spraying water to the flower. The mechanism is fully made of mild steel. The quick return mechanism is broadly used in manufacturing industries, like slotted link shaper machine, such type of machine sustain varying load during the manufacturing the job. We have studied static and dynamic force behaviour of the entire mechanism of particular machine. Our project is concerning to the study of kinematic motion with the help of the Whitworth quick return mechanism. The objective of the project is to investigate the performance of a Crank and lever reciprocating mechanism and to verify that the motion does have a quick return stroke and a slow forward stoke with additionally attaching spraying pump. Additionally the increase in efficiency of the system mechanism is also determined.
