The Final files for this Closing Rocker Arm, enjoy,Solidworks 2014 files with added IGES/STEP,Parasolid,STL & Creo Part files as well. PLEASE COMMENT & PRESS THE LIKE BUTTON IF YOU DOWNLOAD ( THATS THE HEART SHAPED BUTTON- TOP RIGHT) In this Project i have been trying to create a "Motor Cycle Engine" Internal Setup. This model i have learned in one tutorial video.The whole project has been carried out mainly in two software one is PTC CREO & other is Solidworks 2014 for GRAB CAD audience. This will be uploaded part by part as its long one. A rocker arm (in the context of an internal combustion engine of automotive, marine, motorcycle and reciprocating aviation types) is an oscillating lever that conveys radial movement from the cam lobe into linear movement at the poppet valve to open it. One end is raised and lowered by a rotating lobe of the camshaft (either directly or via a tappet (lifter) and pushrod) while the other end acts on the valve stem. When the camshaft lobe raises the outside of the arm, the inside presses down on the valve stem, opening the valve. When the outside of the arm is permitted to return due to the camshafts rotation, the inside rises, allowing the valve spring to close the valve.(Source -Wikipedia) The above rocker arm is a part of Desmodromic Valve System that uses gears and cams to open and close the valves rather than conventional springs. I have uploaded only one fine rendered image with full detailed in Photoshop & Keyshot. I hope you guys like it. ***So stay tuned for more upcoming parts***.
