Week 10- Assembly Workbench

REPORT

AIM

          To design part models and assemble the parts and create drafting and drawing files, taking dimensions from the given references.

QUICK RETURN MECHANISM

A quick return mechanism is an apparatus to produce a reciprocating motion in which the time taken for travel in return stroke is less than in the forward stroke. It is driven by a circular motion source (typically a motor of some sort) and uses a system of links with three turning pairs and a sliding pair.

CV JOINT

A constant-velocity joint (also called a CV joint) is a mechanical coupling which allows the shafts to rotate freely (without an appreciable increase in friction or blacklash) as the angle between the two shafts moves within a certain range.
