Engineering Drawing/Technical Drawing Assembly model

  1. Aug 20, 2012 #1
    Hi all,

    I was just wondering if anybody knew what the attached assembly is and how it works- any information on where to find a CAD model for one would be greatly appreciated, too!

    Thanks guys

    Looks like it converts linear motion of the shaft to circular motion of the disk (or visa-versa). Do you have any more information about it?

    It appears that a belt is attached to the pulley (Item 1). This turns the pinion on the shaft, which is engaged to the horizontal shaft by bevel gear. There on the right hand side is a flywheel, and the left hand side is a counterbalanced reciprocating up/down output motion shaft (Item 2).

    Well geez, anyone can see that it's a walnut cracker! :redface:
    One could use it for a reciprocating pump drive.
    It might make it a good tool to punch out donut holes.
    Or to give Bond, James Bond, his "shaken, not stirred" Martinis.
