Week 10- Assembly Workbench
OBJECTIVE: To create quick return mechanism and CV joint parts in part work bench or generative work bench and assemble them following all the guidelines
INTRODUCTION:
a) 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.
There are three types of quick return mechanism
- Hydraulic drive
- Crank and slotted link mechanism
- Whitworth mechanism
b) CV JOINT:
Constant-velocity joints (also known as homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly used in front wheel drive vehicles. Modern rear wheel drive cars with independent rear suspension typically use CV joints at the ends of the rear axle halfshafts and increasingly use them on the drive shaft.
