Week 10- Assembly Workbench
AIM:-
To make the 3D part from the given 2D drawings and to make the assembly of it and to make the drafting.
QUICK RETURN MECHANISM
A quick return mechanism is used where the rotary inputs are provided to get the reciprocating motion as the output. They were achieved by constraining the relative motion of the links as per the requirement. The quick return mechanism enables the quicker retraction of the reciprocating link or the output link which abruptly reduces the idle time of the machine and improves the output.

CV JOINT
CV joint is a is coupling which is used to transmit power from the transmission to the wheels at constant-velocity. The joints were made in such a way that they can accommodate the up and down movement of the wheels due to the pits and bumps on the road these joints are called as Ball type CV joints and to and from motion at the transmission area to adjust the length of the shaft due the up and down movement of the wheel and this joint is called as Tripod joint.
